A 17 month field study showed that Mysis stenolepis in Passamaquoddy Bay lives for approximately one year. Young are released in shallow water early in spring and grow rapidly during the summer. In the fall, young adults migrate to deeper water where they reach sexual maturity. During winter, transfer of sperm takes place in deeper regions of the Bay, soon after which the males die. Females survive and in spring, migrate to shallow waters to release young after which they die. Females carry an average of 157 young per brood. Developmental stages of the marsupium, marsupial young and post-marsupial young are described and discussed.

Recent escalation of clam prices has contributed to an increase in fishing effort for the soft-shell clam (Mya arenaria) in eastern Canada. Fluctuations in reported landings demonstrate production variability and thus the desirability to manage stocks in an attempt to reduce the interannual variability. The first step is to identify stock differences and multivariate analysis is used for the first time on morphometrics of clams taken from 14 important fishing areas. The computer program, multivariate analysis of covariance (MANCOVA), was employed to "adjust" morphometric characters for variations in size, which was used as the covariate. The union-intersection procedure was used in the comparisons of adjusted mean vectors of samples and multiple comparisons of sample character combinations. The analysis suggests that three identifiable stocks exist in the study area: one on the Atlantic side of Nova Scotia, and two in the Bay of Fundy. The analysis also showed two further areas within the Bay of Fundy which were significantly different, each showing independent characteristics. The study presents new data for clam fishery management, and demonstrates the strength and value of multivariate analysis for stock delineation of sedentary species. molluscs; clams; fisheries; Fundy; invertebrates; shellfish; fauna; Northwest Atlantic; bivalvesAmiro, P.

Retained catches of 1SW salmon in 1991 were 54% of the 1986-1990 mean in SFA, 19.60% in SFA 20, 16% in SFA 21 and 60% in SFA 23. Released catches of MSW salmon decreased to 68% of the previous five year mean in SFA, 19.57% in SFA 20 and 28% in SFA 21. Recreational fisheries in SFA 22 and portions of SFA 23 remained closed for the season because substantially less than the required number of spawners were counted in the index river for the inner Bay of Fundy stocks. Counts of salmon at most facilities in Scotia-Fundy Region were down from those of 1990 and of the previous year means. In-river counts of salmon in the Middle River (SFA 19), Alma, Point Wolfe and Big Salmon rivers (SFAs 22 and 23) were less than the minimum spawning requirement. Escapements to the Petitcodiac and St. Croix rivers (SFA 23) were extremely low. Return rates of hatchery smolts as 1SW fish were the lowest on record for the LaHave River, second lowest for the Saint-John River and third lowest for the Liscomb River. MSW return rates were similarly low. Hatchery returns, however, contributed from 18 to 29% of the MSW returns in rivers where counts are possible. Forecasts of MSW salmon returning to counting facilities in 1992, relative to 1991 returns, are about the same on the Liscomb, SFA 20, 35% lower on the LaHave, SFA 21, and 13% lower on the Saint John River, SFA 23. fish; salmon; fisheries; Fundy; fauna; vertebrate; anadromousAnderson, W.

Recent observations on sea-level change along the Maine coast have led to speculation that the rise in relative sea level is anomalously rapid in some areas, and cannot be solely the product of eustatic sea-level rise. A multidisciplinary study was initiated to determine whether the coastal submergence might be partly the result of neotectonic crustal subsidence. Project activities included bedrock mapping in eastern coastal Maine, where there is a concentration of recent earthquakes and faulting has occurred over much of Phanerozoic time, and in other areas of southern Maine with seismic activity and major fault zones. Evidence of Holocene crustal movement was sought through various research methods involving geodesy, geophysics, and measurement of relative sea-level change. Investigators used several means to determine the amount of vertical crustal movement indicated by sea-level fluctuations, each method being suited to a particular interval of postglacial time. These techniques included analyses of uplifted glaciomarine deltas, salt-marsh accretion, differential erosion of coastal archaeological sites, drowning of salt-marsh dykes and other historic coastal structures and tide-gauge records.The crustal warping study has shown that neotectonic activity in Maine is defined by recurrent seismicity and secular changes in relative sea level. Earthquakes have been recorded historically in the state since the 1700s. They occur most commonly in certain areas of Maine, such as the Passamaquoddy Bay region on the Maine-New Brunswick border. Earthquakes also occur in a less concentrated band subparallel to the coast. Although slumping of late Pleistocene and modern marine sediments was observed on the sea floor near mapped bedrock faults, neither the slumps nor the earthquakes have been conclusively linked to specific faults. No postglacial tectonic movement along bedrock faults has yet been recorded in Maine. The causes of Maine earthquakes are unclear, but probable mechanisms include plate tectonic and glacioisostatic stresses.
Sea level has fluctuated profoundly in the western Gulf of Maine during late Quaternary time, but the rate of sea-level change in this region has not been uniform. Maine has experienced the greatest amount of late-glacial marine submergence and subsequent isostatic emergence of any state or province bordering the Gulf of Maine. Sea level is now rising along the Maine coast at rates exceeding the average eustatic rise. Several lines of evidence suggest that eastern Maine is undergoing more rapid submergence than coastal localities to the southwest, probably because of differential crustal subsidence in the vicinity of Passamaquoddy Bay. The collapse and migration of a crustal bulge which formed along the margin of the Laurentide Ice Sheet may be contributing to the downwarping and seismic activity. However, this theory alone is not adequate to explain the apparent localization of more rapid subsidence in eastern coastal Maine, which is occurring at rates of up to at least 5mm/yr. The distinctive bedrock lithology, structure, and long-term tectonic mobility of this area are believed to cause its present instability. geology; sea-level change; Fundy; seismicity; Gulf of Maine; Passamaquoddy; Quoddy; bedrock; subsidence

Neotectonic activity in Maine is defined by a pattern of recurrent seismicity and secular changes in sea level. Earthquakes have historically been experienced, and continue to occur at several discrete locations in Maine, especially near the city of Eastport. Earthquakes also occur in a less concentrated band subparallel to the present coast. While slumping of modern and Pleistocene muddy sediment is observed near the trace of mapped bedrock faults, no ruptures of bedrock have yet been associated with specific earthquakes. Sea level has fluctuated profoundly in the western Gulf of Maine, and the rate of sea-level change has apparently not been uniform around the margins of the Gulf of Maine during the late Quaternary. Maine has experienced the greatest amount of postglacial drowning and emergence of any locality in the area, although work is needed to better document this. Mareographs indicate that eastern Maine is undergoing more rapid contemporary submergence than localities to the south and west, and that this may result from crustal subsidence in the Eastport area. The simplest explanation for neotectonic activity in the area involves vertical crustal movement as a consequence of the collapse of a "peripheral bulge" which formed during the last ice advance. Continued movement associated with bulge migration, as well as with other sources of stress, is accommodated by earthquakes in areas of weak bedrock and old fault zones. geology; sea-level change; seismicity; Eastport; Gulf of Maine; bedrock; Quoddy; Cobscook; subsidenceAngus, R.

Isoelectric focusing (IEF) was performed on soluble protein extract from whole specimens of third-stage larval sealworm (Pseudoterranova decipiens) recovered from the musculature of 3 fish intermediate host species: Atlantic cod (Gadus morhua), sea raven (Hemitripterus americanus), and rainbow smelt (Osmerus mordax). The fish were collected at various sites in the Canadian Atlantic, and IEF revealed the occurrence of two "variants" within what has previously been considered a single, uniform species of P. decipiens in these waters. The larvae were characterized by the absence ("type I" L sub(3)'s) or presence ("type II" L sub(3)'s) of a sharp, dark-staining protein band with a mean pH of 6.46 pH units. Type I larvae were predominant at two sites sampled in the lower Bay of Fundy, while type II larvae were predominant at three sites sampled in the Gulf of St. Lawrence region. worms; fish; Fundy; invertebrates; annelids; fauna; vertebratesAppy, R.

The fecundity of this common intertidal species has been examined at the point of spawning. The development of reproductive potential by the 2+ year-class, rather than by the 1+ year-class, is confirmed. However, a small reproductive potential was found in the largest members of the 1+ year-class. It is suggested that this capacity could be particularly significant under adverse environmental conditions.

A twelve month study was undertaken of bioaccumulation of PSP toxins in suspension cultured blue mussels in Lord's Cove and Chamcook Harbour, New Brunswick. Biweekly sampling indicated that in mussels unsafe levels of PSP were recorded at both sites between late May and mid August, but that for the remaining months no prohibitive levels were found. In oysters, also sampled biweekly, PSP scores never exceeded the safe levels, although slight increases were evident during the June-July period. Growth was recorded in mussels at both sites, but no net increase in length was seen in the oysters. It is concluded that if suspension culture techniques are utilized, there should be no impact of encysted G. excavata on autumn, winter and spring harvesting and marketing of blue mussels farmed in the southwest Fundy area.

No abstract available.From the introduction: During a stay of about ten days at the biological station such opportunities as presented themselves for the collection and study of the diatoms of the neighbourhood were gladly availed of. The material consisted of dredgings made at various points along the course of the St. Croix River and in Passamaquoddy Bay, together with such an as could be derived from the stomachs of various marine animals, as well as fresh water gatherings from adjacents brooks.
The St. Croix River is in this part of its course really an arm of the sea, being wholly salt and traversed by tidal flow, while the amount of fresh water which enters it, at a distance of about twenty miles from the station, is too small to have any appreciable effect upon its salinity. Near the station the width of the so-called river is about two miles, the depth from 18 to 40 fathoms, and the bottom usually a fine mud. The rise and fall of tide is about twenty-five feet. The rock ledges laid bare at low water are well covered with such algae as Fucus, Ulva, Enteromopha, Cladophora, and Ectocarpus, but are lacking in the Rhodophyceae and other delicate forms which are so often the home of attached diatoms, and from the former but few could be obtained. Tidal pools, contrary to expectation, also afforded but few species, and these not in large numbers. A much richer source of material and giving indirectly a much better notion of the forms likely to be met within the waters of Passamaquoddy Bay, was that of the stomachs of flounders speared at low water in Brandy Cove on the side of which the station is placed. Some interesting gatherings were also made on the shores of Campobello Island at Welshpool and elsewhere. No plankton netting was done during the time of my stay at the station.diatoms; Passamaquoddy; Quoddy; algae; tides; phytoplankton; benthic; flora; invertebrates; fauna; seaweed; St. Croix

No abstract available.Introduction: The Plankton Diatoms constitute a group of peculiar interest in a division of microscopic plants which, in all its branches, afford to the naturalist a field of pleasurable and instructive study.
The term "Plankton" is one which is applied to the entire assemblage of minute, mostly microscopic organisms, including both plants and animals, which are found, often in vast numbers, swimming or floating freely, in the waters of ponds, lakes or in the open ocean, having no connection with the solid earth, but deriving, their food supply from the medium in which they live. So far as the animal kingdom is concerned this floating population embraces members of several groups, such as Infusoria, Foraminifera, and Radiolaria, together with larval forms of Echinoderms, Annelids, Polyzoa, Crustacea and Mollusca, but, as regards plant life, this is confined, with the exception of the small group known as the Peridineae, to the family of the Diatomaceae. These are minute unicellular algae of which the most notable peculiarity is the secreting of a siliceous shell or lorica, determining their form and strength, and which is practically indestructible.
Existing as they do in such enormous numbers in the purer oceanic waters, the plankton Diatoms constitute a very large part of the food of higher oceanic organisms, as is proved by the fact that they are found in such large numbers in the stomachs of marine animals such as echinoderms, crustacea, molluscs and even fishes. Even where these animals are not themselves direct plankton feeders, like the members of the herring and mackerel families, they nevertheless rely for their nourishment upon smaller animals, Copepods and the like, which are thus supported, so that the Diatoms may very properly be regarded as affording the basic food supply for marine life, even in its highest forms.
The features which especially characterize the so-called Plankton Diatoms are those of their adaptation to a life of flotation. This is partly effected by a relative reduction in the amount of silica contained in their cell walls, reducing their specific gravity, but mainly in other ways, such as by the nature of their forms or the development of expedients which favor buoyancy. Thus in certain genera (Coscinodiscus, Actinocyclus, Actinoptychus & c.) the form is that of a nearly flat or slightly convex disc, exposing a large surface in proportion to the thickness of the cell; in others (such as Biddulphia, Melosira, Skeletonema, Rhabdonema, Tabellaria &c.) the frustules, though individually small, are attached to each other to form filaments or chains; while in still others, and these the most characteristic, the desired object is attained by the development of processes, arms or horns, projecting from the cells, and which are often of extravagant length?(Chaetoceros, Bacteriastrum, Nitschia, &c.)?the presence of oil globules in the cells probably also assists in certain cases.
The Biology of the Plankton-Diatoms has, until within a few years, been the subject of comparatively little study; but now that their importance in connection with their relations to the support of other forms of life has been generally recognized, observers at the principal Biological Stations, both in America and Europe, have been giving them much attention. Both their classification and nomenclature are, however, still in a very unsatisfactory state, and the literature of the subject is comparatively small. So far as New Brunswick is concerned absolutely nothing has previously been published, though references to some of the characteristic species have been made by the writer in earlier articles on the Diatoms of the New Brunswick seaboard. Dr. Ramsay Wright has also described and figured some of the species found by him in the Plankton of Canso, N.S. (Contributions to Canadian Biology, 1902-1905).
The materials upon which this paper is based were obtained mainly from Passamaquoddy Bay and the adjoining waters of the Bay of Fundy, and in connection with the work of the Marine Biological Station at St. Andrews. In making the collections very fine silken tow-nets were employed, and their contents examined while still fresh and in their proper element, chemical treatment being apt to disintegrate the concatenate forms, while mounting in balsam will often cause delicate forms, though readily seen in water or dry, to become nearly or quite invisible. It is, however, often necessary to treat the material, after removal of salt by washing and decantation, with Nitric acid, in order to remove the vast number of Copepods and other organisms with which they are associated as well as foreign matters adherent to the Diatoms themselves.
The most frequent accompaniments of the plankton-diatoms, in addition to the Crustacea, are silico-flagellate Infusoria of the genera Amphorella and Tintinopsis. The literature available to the author in his study of the Plankton of the New Brunswick waters includes the following: ? Smith's Synopsis of British Diatomaceae, Van Heurck's Diatomees de Belgium, Wolle's Diatoms of North America, Nordisches Plankton?Brandt and Apstein?Kiel, Brightwell?On the Filamentous, Long Horned Diatomaceae, (Quarterly Microscopical Journal, London, Vol. IV.). Of these the first three are of a general nature. Only the last two relate especially to the Plankton. In an article by Professor Ramsay Wright in "Contributions to Canadian Biology," published in 39th "Annual Report of the Department of Marine and Fisheries?Canada" some descriptions and figures of the forms occurring at Canso, Nova Scotia are given, and these have been of service in the study of the New Brunswick forms.
In the following account of the species entering into the composition of the Plankton those which may be regarded as especially characteristic of the latter, exhibiting the most marked adaptations to a life of flotation, will be first considered, to be followed by those which, though less marked in this respect, are nevertheless of general or frequent occurrence.
Professor W. A. Herdman, F.R.S. of Liverpool University, who has been in charge of special plankton investigations around the Isle of Man, gives six genera as those which are especially characteristic of the plankton flora of that region, and it is interesting to note that, with one possible exception (Lauderia) all of these occur and in most instances are abundant in the Bay of Fundy and adjacent waters. These genera are Chaetoceros, Rhizosolenia, Biddulphia, Coscinodiscus, Thalassiosira and Lauderia, to which may be added Skeletonema, Bacteriastrum and Asterionella.algae; diatoms; Fundy; phytoplankton; Passamaquoddy; flora; food web; Quoddy

Of those who visit the Biological Station at St. Andrews, whether as tourists or as members of the staff and participants in its work, there are many who, attracted by the unusual beauty of its surroundings, would like to know something of the causes to which that beauty is due. I have therefore been asked by members of the Biological Board to prepare a short sketch of the geological features of the region. These, of course, are fully detailed in the reports of the Canadian Geological Survey, but are contained in many different volumes, and are not always easily accessible and are so associated with the geology of wider areas as to make it somewhat difficult to obtain the desired facts. In this sketch only those are given which seem to be of general interest. geology; Passamaquoddy; St. Croix; QuoddyBailey, L. W. (1917). "Notes on the phytoplankton of the Bay of Fundy and Passamaquoddy Bay." Contributions of Canadian Biology 1915/16: 93.
In previous publications relating to the Diatoms of New Brunswick and Prince Edward Island, fairly complete lists of these, as found at a series of localities along the Atlantic coast, have been given, but no attempt has been made to distinguish between littoral or neritic and deeper water or planktonic forms, or to show the relations of either of these to differences of season and environment. Yet it is obvious that, as with other plants, such varying relationships do exist, and as their varying abundance must directly affect the food supply of the different animals, such as young fishes, oysters, etc., which feed upon them as complete a knowledge as possible upon these points is highly desirable.The present notes are intended mainly to apply to the Phyto-Plankton of the Bay of Fundy and Passamaquoddy Bay, though occasional references are made to points on the north shore of New Brunswick and to Prince Edward Island. Moreover, as the line between planktonic and non-planktonic forms is ill-defined, species ordinarily regarded as neritic are not unfrequently met with far from shore, and may even constitute a considerable part of any planktonic gathering. In the following pages, lists of such gatherings from numerous localities are given for the various months of the year, excepting December, for which latter month no data are yet available.phytoplankton; diatoms; Fundy; Passamaquoddy; flora; food web; Quoddy

To prepare anything like a complete list of the Diatoms of Canada is an impossibility. Not only is the region of enormous extent, embracing the whole breadth of America where that breadth is the greatest and extending northward into Arctic regions, but it also presents a great diversity of physical conditions to which these plants, not-withstanding their minuteness and comparatively simple structure, must, like other plants, respond to a greater or less degree. The species of the coast are, of course, as a whole unlike those of the interior, though the outflow of rivers and the inflow of tidal currents, such as that of the St. John River, produces in many instances a singular admixture of the two. In the interior also there is a wide diversity in the distribution, almost every locality having some features of its own; at some points one or two species, though abundant, make up the whole of the collection, while at others, possibly not far removed, they exhibit great diversity. Some of the interior lakes of Canada, like the Quill Lakes in Saskatchewan, are saline, and in these quite a number of typically marine genera have been met with in great abundance. It has been suggested that the presence of these may be due to transportation by migratory birds, but it is worth noticing that the species found are for the most part unlike those of either the Atlantic or Pacific seaboards. Differences of depth, temperature, density, salinity and composition in different waters all have their influence on the distribution of Diatoms, as do currents in those of the sea. algae; diatoms; phytoplankton; distribution; Northwest Atlantic; oceanography; inventory; flora; tides; hydrographyBailey, W.

Observations of temperatures and salinities, on a monthly basis, in the Outer Quoddy Region (Figure 1) of the Bay of Fundy since 1924, have provided a means of following the hydrographic conditions of the Bay of Fundy. These observations are taken about the middle of each month at Prince Station 5 (Lat. 44° 56'48"N.) ( Long. 66° 48'41"W.). Data from Station 5 have been used by several authors to illustrate the annual temperature cycle in relation to their specific investigations. Hachey (1934) determined replacements of the waters of the Bay of Fundy through variations in temperature at Station 5, and used these data as well to show the annual cycles of temperatures and salinities during his general survey of the hydrographic conditions in the Bay of Fundy in 1929 and 1930 (Hachey and Bailey, 1952). A similar procedure was used by Watson (1935) in dealing with the mixing and residual currents in the Bay of Fundy. Up to the present time, there have been no attempts to use this large body of data to establish mean values and to study variations that have occurred over the period 1924-52.

Journal of Biology Board of Canada 2(4): 401.
Using condition factor as criterion of fatness, investigation confirms the report of those handling them that herring are characteristically fat in each locality of the Passamaquoddy region of southern New Brunswick. Herring feed by an act of capture, moving towards the source of light in doing so. They do not feed in darkness, requiring light about as strong as moonlight. Gastric digestion takes 25 1/2 hours at 6° and 6 and 7 hours at 20° C. in herring 14 to 16 cm. long, where fattest, herring contain the most food and of the larger kinds. In some localities herring have more food and of special kinds after moonlight nights. Herring are mainly in upper layers of water in summer, and nearer surface when light intensity is low. Correlation between fatness of herring and either the total quantity of food present locally or the local degree of concentration of food in the water is quite imperfect. Good correlation exists between fatness and quantity of food present near the surface in the particular locality. In localities where herring have more food after moonlight nights, food organisms are much more abundant near the surface in moonlight than in sunlight. Food organisms are most concentrated in passages and near shoals where thorough mixing of the water occurs. In the passages at the mouth of Passamaquoddy Bay, deepwater forms from the Gulf of Maine are available at the surface at all times of the day, giving the fattest herring. To exhibit characteristic fatness herring must remain some weeks in the locality . herring; Passamaquoddy; Quoddy; feeding; fish; fauna; vertebrateBay of Fundy Weir Fishermen's Association (1973).

Shoreland quality for recreation, Fisheries Research Board of Canada Technical Report (No. 428-8), Fisheries Research Board of Canada.
The shoreline and coastal waters of southwestern New Brunswick have a significant potential for a wide spectrum of recreational activities. Of the approximately 150 square miles of shoreland from the Maine border to the city of Saint John, nearly 50 square miles have a high capability for family-oriented recreational pursuits based on the physical and aesthetic characteristics of coastal lands and waters. Passamaquoddy Bay has the highest potential for intensive recreational use with nearly the entire coastline being rated moderate to moderate-high according to the Canada Land Inventory recreation survey. For this coastal area practically all of the best potential uses identified are among those which would be seriously affected by oil contaminating the beaches and inshore waters. Although it is difficult to forecast the exact nature of the effects of a marine oil spill on water-based recreational activities it is important to recognize that not only would the impact have to be evaluated in terms of immediate and long-term financial losses to private and commercial interest, but some realistic appraisals would have to be made of significant aesthetic and social losses.

The Dennys River: An Atlantic salmon river management report, State of Maine, Atlantic Sea Run Salmon Commission.
No abstract available.Introduction: The Dennys River is reported to have been the only Maine river where Atlantic salmon angling preceded the erection of impassable dams (Kendall 1894). This long history of angling may account for the sustained interest in the fishery as evidenced by the involvement of local citizens over a period approaching 150 years.
The Dennys River was selected as the site of the first intensive study of Atlantic salmon in eastern Maine (Goodwin 1942). It was selected because of its native salmon population, lack of pollution and obstructions, and its famed Atlantic salmon angling...
This updated Dennys River report includes a condensation of the original survey data made by Fletcher (1960) as part of a statewide biological survey of Maine lakes, rivers and streams. The anadromous Atlantic salmon, the center of concern of this report, is discussed from a broad base of knowledge of the biology of the species and an accumulation of field experience involving the management and enhancement of the Atlantic salmon resource in the Dennys River.

During the summer of 1912 the Bureau of Fisheries, with the cooperation of the Museum of Comparative Zoology of Harvard University, commenced an oceanographic and biological survey of the Gulf of Maine, with special reference to its fishes, to its floating plants and animals (plankton), to the physical and chemical state of its waters, and to the circulation of the latter. Cruises were made on the Fisheries schooner Grampus during the summers and autumns of 1912, 1913, 1914, 1915 and 1916, and during the winters and springs of 1913 and 1915. The work was interrupted by the war, but was resumed with a cruise of the Fisheries steamer Albatross in the late winter and spring of 1920, and was continued by the Fisheries steamer Halcyon, during the winter and spring of 1920-21, and the summers of 1921 and 1922.The first part of the general report, dealing with the fishes, was published in 1925, as Bulletin 40 (Pt. 1) of the United States Bureau of Fisheries; subsequent parts describing the plankton of the offshore waters of the Gulf and the physical characteristics of its waters were published in 1926-27, as Part 2.
The preparation of the section on the fishes was assigned originally to W. W. Welsh, who had gathered a large body of original observations on the growth, reproduction, diet, and other phases of the lives of many of the more important species. The report was far advanced when it was interrupted by his untimely death, and H. B. Bigelow undertook to carry it to publication along the lines originally laid down. The new edition, entailing a general revision and the addition of much new material, has been prepared jointly by H. B. Bigelow and by W. C. Schroeder. fish; Gulf of Maine; fauna; inventory; life history; plankton; vertebrates

From the introduction: During the summer of 1950, a preliminary survey of aquatic invertebrate fauna was conducted by the writer in the coastal regions of the Canadian Maritime Provinces. The services of Mr. Colin L. Thacker, who accompanied the author from June 1 to August 31, contributed greatly to the success of the field work. The purpose of the survey was twofold?namely: (1) to determine the distribution of the fouling barnacles of Canadian Atlantic coastal waters and find a locality suitable for detailed study of the ecology of estuarine forms, and (2), in connection with this work, to make a collection of marine and fresh-water organisms for acquistion to the invertebrate collections of the National Museum.

During the period June 16 to August 22, 1958, the writer conducted a survey of intertidal and shallow-water marine invertebrates of the Bay of Fundy region, Eastern Canada. The material and station data from Minas Basin and Minas Channel have been included in a previous report (Bousfield and Leim, 1960). Records of molluscs have been embodied in a general account on Canadian Atlantic sea shells (Bousfield, 1960). Herewith is presented a list of the crustaceans and other arthropods collected intertidally in the Bay of Fundy proper, with a discussion of zoogeographical and ecological affinities of the fauna. A total of 68 stations were visited, at 32 of which marine specimens were collected and hydrographical measurements made (see Figure 1; Table 1). Also included are selected records of crustaceans obtained in 1950 from the St. John estuary and other Fundy localities (Figure 1; Table 2; and Bousfield, 1952, Figure 12).

The Maine herring fishery during the period 1947-1958 has averaged 148 million pounds and has ranged from 75 to 200 million pounds. Catches in the Passamaquoddy Project area have averaged over 6 million pounds and ranged from 2 to almost 11 million pounds. Maine herring landings immediately outside the dams averaged 6 million pounds, and the remainder of Washington County 28 million pounds. Yearly catch fluctuations in the Project area fisheries are great, for example, the low pool fishery caught 49 thousand pounds in 1947 and over 6 million pounds in 1954. The Maine herring fishery is seasonal; most of the catch occurs between June and October. In the two pools, most of the herring have been caught between August and October. Along the entire Maine coast, stop seines have been the most productive gear; in the Project area, seiners took 77 per cent of the low pool catch, but only l7 per cent of the high pool catch. Since 1947, the number of weirs has fluctuated markedly, from none to 16 in the low pool and 14 to 31 in the high pool. herring; fisheries; Passamaquoddy; Quoddy; Gulf of Maine; tidal power; fauna; fish; vertebratesBrady, S.

Examination of 1041 trap-caught lobsters from the Bay of Fundy, Grand Manan, Browns and German Banks, south and east Nova Scotia, and Northumberland Strait indicated that P. homari occurs on American lobsters, H. americanus, throughout Canadian Maritime waters. Male lobsters were rarely infected and ovigerous females generally had a higher prevalence (percentage infected) and mean intensity of infection (number of nemerteans per infected lobster) than nonovigerous females. lobsters; distribution; Fundy; Northwest Atlantic; parasites; fisheries; annelids; invertebrates; crustaceans; fauna; shellfishBraune, B.

A study of three species of migrating larids was undertaken off Deer Island, New Brunswick, to compare feeding methods and diving rates of birds exploiting various prey types. Bonaparte's gulls (Larus philadelphia) fed mainly by diving (dipping and plunging) and surface seizing, whereas Common and Arctic terns (Sterna hirundo and S. paradisaea) acquired food by diving only. Common and Arctic terns foraged from greater heights than Bonaparte's gulls, and both the gulls and the terns maintained a higher foraging height while feeding on small fish than while feeding on euphausiids or, in the case of the gulls, insects. Common and Arctic terns had a steeper dive angle than Bonaparte's gulls, and both the gulls and the terns dove more steeply when feeding on small fish than on euphausiids. The highest diving rate occurred when Bonaparte's gulls were dipping for insects trapped in the water surface layer. There was no significant difference in mean dipping or plunging rates between the gulls and the terns feeding on euphausiids or small fish. Bonaparte's gulls had a lower mean rate of incomplete dives than did terns, probably because of the gulls' lesser aerial maneuverability reducing the likelihood of altering course after dive initiation. The mean dipping rate was higher than the mean plunging rate for both the gulls and the terns since most food was taken at the surface, and plunges were necessary only for deeper prey (usually small fish). Intervals between hovering and diving were similar for both the gulls and the terns. Passamaquoddy; Quoddy; migration; seabirds; gulls; terns; ecology; feeding; fauna; vertebrates; birdsBraune, B.

A bioenergetics-based budget that predicts net total Hg loss during the period of autumn moult was calculated for adult Bonaparte's gulls (Larus philadelphia) in the southwestern Bay of Fundy, Canada. Daily food consumption and, hence, ingestion of Hg measured in prey samples, was calculated from estimated energy requirements during the period of moult. The amount of Hg eliminated was estimated from analyses of Hg content in-excreta and feathers. Elimination of Hg via the feathers accounted for 68% of the total loss from the body in females and 59% in males during the period of autumn moult. metals; contaminants; gulls; moult; Fundy; feeding; seabirds; fauna; vertebrates; pollution; birdsBraune, B.

No significant sex differences were detected in Hg concentrations in primary feathers, pectoral muscle, brain, liver, and kidney tissues of fall migrating juvenile and second-year Bonaparte's gulls (Larus philadelphia) collected in the Quoddy region. Adults showed sexual differences only in the first 5 primary feathers, and in muscle, kidney and brain. Differences in Hg concentrations among age groups were reflected in the primary feathers and body tissues, but as the molt progressed, Hg concentrations decreased as they converged toward a minimum asymptotic Hg level for each tissue. This suggests that the body burden of Hg was reduced through its redistribution from the body tissues into the growing feathers. Mercury concentrations in premolt head feathers (pre-egg-laying) did not vary significantly between adult females and males, whereas Hg concentrations in postmolt feathers (post-egg-laying) were significantly lower in females, suggesting that egg-laying was also a route for Hg elimination.metals; Quoddy; gulls; moult; contaminants; reproduction; ecology; seabirds; fauna; vertebrates; pollution; birdsBrawn, V.

The depth of schools of immature herring in Passamaquoddy Bay was determined from echo sounder records taken from 1947 to 1958. The records gave no information on the presence of herring between the surface and 14 ft, and any herring in this zone have been omitted from the calculations. The herring schools showed diurnal vertical movements, being closer to the surface by night than by day in every month of the year. From May until December the median depth varied from 30 to 44 ft by day and from 21 to 26 ft by night. From January to April the schools were deeper in the water by day with a median depth of 83 to 126 ft, though still rising towards the surface at night, to a median depth of 36 ft in February. No correlation was found between the mean solar radiation for the daylight hours and the median depth of herring by day in each month. Between 2° and 4-7° C there was a significant inverse correlation between water temperature and the depth of the herring by day, but as temperature increased above 7° C, up to 12° , there was no further decrease in median depth. herring; Passamaquoddy; Quoddy; distribution; ecology; fish; fauna; vertebrates; temperatureBrinkhurst, R.

Genetic structure of eight Northwest Atlantic populations of the marine polychaete Glycera dibranchiata Ehlers was examined with starch gel electrophoresis. Samples were collected during summer and fall 1981, and seven polymorphic and four monomorphic loci were consistently scored. Average heterozygosity (0.126) and percent polymorphic loci (59.3) were comparable to the averages reported for marine invertebrates. Minimum genetic distances between populations ranged from 0.003 to 0.093, levels typically associated with local populations of the same species in other taxa. Based on these data, inter- and intra-estuarine migration and gene flow appear to be low. Only two populations, separated by 13 km along the same river in New Brunswick, Canada, were not genetically different from each other. These findings may have relevance for management strategies in bloodworms.Gulf of Maine; genetics; annelids; invertebrates; fauna; wormsBrooks, A. (1993).

A terrain-following (sigma-coordinate) hydrodynamic model with 10 vertical levels and horizontal resolution of 225 m on a 70 x 60 grid has been applied to Cobscook Bay, located in the eastern Gulf of Maine near the mouth of the Bay of Fundy. The model-predicted tidal circulation is consistent with many of the known aspects of the water movements in the bay. Comparison against the current measured at a near-shore site shows reasonable agreement in amplitude, but finer model grid resolution approaching 100 m is necessary to resolve the eddy characteristics of the observed currents.

A three-dimensional sigma-coordinate numerical model was used to simulate the circulation in Passamaquoddy Bay, eastern Gulf of Maine where the mean tidal range is 5.6 m. The model was forced by tidal height variations at the oceanic boundary, fresh water runoff from rivers, and parameterized fluxes of heat and momentum at the sea surface and sea bottom. Simulations were run for cases approximating the natural system, and also for cases modified to include the gates, dams and powerhouse structures of a tidal power project that was previously under consideration for the region.tidal power; Passamaquoddy; Quoddy; hydrography; circulation; currents; oceanographyBrown, B. (1993). A classification system of marine and estuarine habitats in Maine. Part 1: Benthic habitats, Maine Natural Areas Program, Department of Economic and Community Development.
Summary: This report describes a preliminary classification system for marine and estuarine benthic habitats in Maine. It builds on a number of other classification schemes for natural assemblages. An ecosystem approach to this habitat classiflcation has been taken that addresses abiotic as well as biotic factors. Factors included in the hierarchy are substratum, depth, energy level, and salinity. Additional modifiers are also included where appropriate. Diagnostic and common species known to be associated with the habitats are described. Representative sites for the reported habitats are presented. Based on analysis of literature and discussions with marine scientists, a total of 56 intertidal and subtidal habitats are described for marine and estuarine areas.Several trends were identified by this effort. Some areas are better studied than others. More is known about intertidal habitats than subtidal ones, common species than rare ones, nearshore habitats than offshore habitats, summer composition of assemblages than the winter composition, and polyhaline estuarine habitats than oligohaline estuarine habitats. This classification system can be used in numerous ways including, but not limited to, the following: (a) to prioritize habitats for management and protection, (b) to inventory biodiversity of Maine's marine and estuarine areas, and (c) to assess the influence of human disturbance of these natural systems. It is anticipated that future work will entail developing a classification for pelagic habitats, ranking of habitats for uses in their management, and initiating inventory of selected habitats as well as verifying some of the literature analyzed in development of the classification. intertidal; subtidal; estuarine; benthic; habitats; inventory

The possible effects of oil spills on marine birds, Fisheries Research Board of Canada Technical Report (No. 428-5), Fisheries Research Board of Canada.
The Passamaquoddy Bay area is an important wintering area or migratory stopover for several species of diving ducks, as well as phalaropes, Greater Shearwaters and Kittiwakes. All of these could be directly affected by oil slicks in the area. Brant Geese could be indirectly affected, through contamination of the eelgrass beds on which they feed. It is unlikely that any single spill would lead to the extinction of any of these species; however, the cumulative effect of relatively small spills could be serious.

"The pelagic ecology of the grey and red-necked phalaropes Phalaropus fulicarius and P. lobatus in the Bay of Fundy, eastern Canada." Ibis 130: 234.
The outer Bay of Fundy, eastern Canada, is an important feeding area for migrant grey and red-necked phalaropes Phalaropus fulicarius and P. lobatus in late summer. The birds feed on copepod-sized zooplankton, brought to the surface by the passage of strong tidal streams over shallow, rocky "ledges", and concentrated there in upwelling and convergence "streaks". Feeding phalaropes are significantly more abundant in the "streaks" than in adjacent "control" areas. Red-necked phalaropes are the more common species; they prefer the New Brunswick shore, where copepod biomass is high and the species-community is dominated by large, Stage VI-V Calanus finmarchicus. It is concluded that upwellings, convergences, and other oceanographic phenomena that concentrate zooplankton at the surface are the principal factors influencing the pelagic ecology of phalaropes.ecology; Fundy; feeding; phalaropes; shorebirds; invertebrates; zooplankton; fauna; vertebrates; rocky; birdsBrown, R.

Copepods and cladocerans were collected, mainly in August, from the top 0.25 m of the water column in the outer Bay of Fundy, off Brier Island, Nova Scotia in 1975-1978, Deer Island, New Brunswick in 1977-1978, and Grand Manan Island, New Brunswick in 1981. In 1975-1977, the dominant species at the surface off Brier Island were stage CIV-I Calanus finmarchicus and CVI-V Pseudocalanus sp. The copepods Acartia spp., Anomalocera pattersonii, Centropages sp., Eurytemora spp., and Oithonia similis and the cladocerans Evadne sp. and Podon sp. also occurred regularly. The relative abundance of Calanus finmarchicus declined during the period July-October 1976, though the proportion of stages CVI-V increased. The relative proportions of Pseudocalanus sp., and of its stages CVI-V, both declined during the same period. zooplankton; Fundy; distribution; copepods; invertebrates; faunaBumpus, D. F. (1960).

Significant positive correlations were found for Atlantic cod (Gadus morhua) haddock (Melanogrammus aeglefinus), alewife (Alosa pseudoharengus), Atlantic herring (Clupea harengus harengus), and scallop (Placopecten magellanicus), with lag times that are biologically appropriate for the time from hatching to recruitment into the fishery. A significant negative correlation with the nodal cycle was evident for Atlantic menhaden (Brevoortia tyrannus), for which this area constitutes the most northerly part of its range.

Chandler (1976). Historical statistics of landings of inshore species in the Maritime Provinces, 1947-73, Fisheries Marine Service Res. Dev. Technical Report (No. 639).
Statistics Canada (formerly Dominion Bureau of Statistics (DBS)) landing figures from 1947-1973 have been compiled for 22 species or species groupings of fish, shellfish, and marine plants that are principally harvested in Canadian coastal waters, and for which Statistics Canada statistics are the single most reliable information source on trends in marine production. In selecting species to include in this compilation, priority was given to those that best reflect local changes in production of renewable resources around the Maritimes. However, in a commentary on the main features of the biology of fishery for, and trends in production of, the selected species, attention is drawn to numerous exceptions to the above generalization, that are not immediately apparent from the landing figures themselves.An overall examination of landing trends distinguished two principal groups of species: those for which fisheries have been in effect since before the present system of fisheries districts was instituted (1947). These include most of our high unit-value species, for many of which downward trends in landings are in effect. A second group of fisheries began, or intensified, in the 1960s, largely as a result of diversion from more traditional resources. This group includes a number of high volume, low unit-value species (e.g., Irish moss, Chondrus crispus), and has contributed to an overall increase in landed weights since the mid-1960s. There is evidence, however, that, after allowance is made for rapid increases in unit price paid over the last decade, the upward trend in total landed value for all "inshore" species would be reversed to show a slow decline in real value of landed resources over the last two decades. fish; shellfish; fauna; fisheries; distribution; Northwest Atlantic; Fundy; vertebrates

No abstract available. Introduction: The commerical landings of invertebrates and marine plants during the years 1973-78 are presented and discussed for the Bay of Fundy in general and the Passamaquoddy region (Charlotte County, New Brunswick) in particular (Figure 1). The purpose of this paper is to indicate quantities and values of these landings that would be at risk should an oil spill occur in the Passamaquoddy region, and to update the similar biological information contained in Wilder et al. (1974). Most of the statistical information was obtained from Statistics Canada, Halifax.

Sphyrion-tagged lobsters (H. americanus) recaptured in the Bay of Fundy during 1977-80 yielded mean annual molt increment and molt probability data for male and female lobsters of 60-171 mm carapace length from which growth curves were calculated. In addition, a multiple regression model was used to generate growth curves from premolt size, number of molt periods lobsters were exposed to, and growth increment data for 850 tagged lobsters at liberty for 1-5 years. Von Bertalanffy parameters were calculated from these empirical growth curves, which suggest that lobsters take 20-35 years from time of hatching to reach 200 mm carapace length in the Bay of Fundy. Analysis of pleopods indicated that the majority of lobsters molt during August-October each year.

A total of 2,139 ovigerous lobsters (Homarus americanus) were tagged and egg development recorded off Grand Manan during 1982-83. Recaptures August 1982 to January 1984 totalled 1877, representing 1046 individuals including 457 captured two to ten times. Single recapture data indicate that the majority (75%) of the lobsters moved <15 km. Multiple recapture and depth at recapture data gave more information on the movements. Many lobsters showed seasonal shallow-deep migrations of >20 km with recaptures in shallow (>20 m) water during summer-fall and in deep (>200 m) water during winter spring. Many ovigerous females returned to the Grand Manan area the following summer. Seasonal depth migrations of ovigerous lobsters appear to be associated with maximizing temperatures which provide sufficient degree-days for completion of egg development. migration; lobsters; fisheries; Fundy; reproduction; crustaceans; invertebrates; shellfish; fauna; Grand Manan; QuoddyCampbell, A.

The relative abundance, size, and sex frequencies of trap-caught lobsters (Homarus americanus) were determined from 5 areas near the northern end of Grand Manan during August-September 1982 and August 1983. Berried females may seek and congregate in areas favourable for egg development and larval dispersal. During summer, shallow areas provide warmer water than deeper areas and therefore allow faster egg development and egg extrusion. Also, the shallow waters with strong tidal currents would allow rapid dispersal of newly hatched larvae.

Historical (1877-1980) annual landings, values, effort and regulations are presented for the Grand Manan lobster fishery. Lobster landings have been relatively stable at 322,000 kg although the value of lobsters has increased from <$l.O to >= $6.0/kg from 1948 to 1979. Over 80% (by weight) of all commercial lobsters trapped each fishing season are caught in the shallow < 40 fath, 73 m) waters off southern Grand Manan. Fishermen from North Head, however, have increased their catch from 9% of the total Grand Manan landings during the 1974-75 season, to 13% in the 1979-80 season by directing their efforts in searching for large, mature lobsters in deep (41-110 fath, 75-201 m) waters east and south of Grand Manan. The percentage of 'jumbo' lobsters (>=127 mm carapace length) of total landed catch at North Head has increased from 27% in 1975-76 to 52% in 1979-80.Initial population biomass estimates of commercial-sized lobsters by using Leslie regression analysis of catch-per-unit-effort data for 7 yr ranged from 346,432 to 569,320 kg for the 1978-79 and 1952-53 fishing seasons, respectively, off southern Grand Manan. Exploitation rates have generally increased from 56.4% during l948-49 to 84.9% during 1979-80 in southern Grand Manan. lobsters; fauna; Grand Manan; Quoddy; fisheries; crustaceans; invertebrates; shellfish
Campbell, A. and A. B. Stasko (1986). "Movements of lobsters (Homarus americanus) tagged in the Bay of Fundy, Canada." Marine Biology 92: 393.
Of the 18,359 American lobsters (H. americanus) tagged and released at three locations in the Bay of Fundy during 1977-1980, 5,375 lobsters (29.3%) were recaptured within 6 years of release. Mature lobsters (greater than or equal to 95 mm carapace length, CL) on average moved significantly greater distances than immature lobsters (<95 mm CL). Many (16.4%) of the mature lobsters were recaptured >92.6 km (50 nautical miles) from the release sites; the farthest distance moved was 798 km for a male at liberty for 3.5 years. Examination of the direction of movements indicates some intermixing of lobsters within the Bay of Fundy, and throughout the Gulf of Maine and the adjoining continental shelf and slopes. Mature lobsters were recaptured in deeper waters during winter than during summer. The seasonal shallow-deep migration of mature lobsters in the Bay of Fundy is possibly associated with maximizing degree-days for molting, growth, gonadal development, and egg development. In some areas, mature females on average moved farther and seasonally earlier into deeper waters than mature males. lobsters; Fundy; Gulf of Maine; crustaceans; invertebrates; shellfish; fauna; distribution; life history; moultCampbell, D.

The possible effects of tidal amplitudes altered by Fundy tidal power development upon potential fish production in the Gulf of Maine are examined with a marine ecosystem model. Three areas off the Maine coast are delineated on the basis of winds, tides, and the extent of vertical mixing. If the construction of a tidal power dam in the upper Bay of Fundy results in a 5-10% increase in tidal amplitude, the first-order model predicts that enhanced vertical mixing from May to October will increase potential fish production along the Maine west coast by 7-12%. Fish production along the Maine east coast and in offshore waters is predicted to remain at present levels. tidal power; Gulf of Maine; hydrography; fish; fauna; vertebrates; oceanography; FundyCanada Department of Fisheries and Oceans, Maine Department of Marine Resources, et al.

The St. Croix River, a US/Canada international river bordering the state of Maine and the province of New Brunswick, drains southwesterly into Passamaquoddy Bay of the Bay of Fundy. The St. Croix River has undergone dramatic changes over the years as the result of development of industry related activities; mainly pulp mill and power generation activities. Atlantic salmon and other anadromous fish species decreased dramatically as the industrial development expanded throughout the system. Fisheries management to rehabilitate these species became a matter of international concern and to deal with this a joint US/Canada St. Croix River Steering Committee was established for the purpose of seeking mutual agreement on a course of action to rebuild the depleted stocks and to develop a long-term river specific management strategy. This report is a result of the Steering Committee and its subcommittee's deliberations and recommends the appropriate steps to be followed to manage the anadromous fish resources of the St. Croix during the 1980s and 1990s. fisheries; Passamaquoddy; Quoddy; industry; anadromous; fish; salmon; fauna; St. Croix; vertebrates; plansCanada Department of the Environment (1974).

Introduction: In response to the request for current and recent information on seabirds and other species using the coastal zone in the Passamquoddy and adjacent region, the following data are taken from hitherto unpublished files. Caveats concerning the utility of the data are included as appropriate in each section. Detailed counts for many species, and particularly the seasonal variations, are wanting; nevertheless, there are ample data to illustrate the very high usage of the Passamaquoddy area by seabirds and others throughout the year.

Dinoflagellates belonging to the Protogonyaulax catenella/tamarensis species complex are causative organisms responsible for paralytic shellfish poisoning in coastal waters. Morphological features used to discriminate between members of this group can be variable, particularly when brought into culture. Other characteristics, including bioluminescence and toxin profiles also vary within a morphological species, and appear inadequate as species descriptors. Electrophoretic profiles of 10 enzymes, including both non-specific hydrolases and pyridine-linked dehydrogenases, have been compared for clonal and multiclonal isolates. Variability both within and between populations from diverse geographical locations (B. C., Washington State, Bay of Fundy, England, Portugal, and New Zealand), has been assessed.paralytic shellfish poisoning; Fundy; dinoflagellates; genetics; phytoplankton; floraChas. T. Main Inc.

The green sea urchin has recently become one of Maine's most valuable resources. Urchin roe is a delicacy in Europe, Japan, and in some of the ethnic markets of the northeastern US, but it is the Japanese market that has provided the stimulus to the rapid development of this fishery. The success of the fishery is due to an abundant resource, a favorable value between the yen and the dollar, and the development of harvesting and processing techniques that suit the quality that is demanded by the Japanese market. Can the market be maintained, given the distance and the demand for product quality? What fishing practices will best sustain the resource? What are the ecological implications of removing large quantities of urchins from the bottom habitat along the coast? These are questions that we will face over the next few years as this new fishery becomes established. urchins; fisheries; ecology; Gulf of Maine; invertebrates; fauna; economicsChenoweth, S. and J.

During 1957 and 1958, approximately 10,000 drift bottles were released in the Quoddy Region with a return of 25%. The results have been analyzed and the surface drift inferred on a monthly and seasonal basis. It is concluded that, on the average, there is a counter-clockwise circulation in Passamaquoddy Bay, an outflow through Western Passage, a variable flow in Letite Passage, an outflow on the Campobello side of Head Harbour Passage, and an inflow along the Deer Island side of the Passage. In the Outer Quoddy Region, there is evidence of a clockwise circulation around The Wolves, a variable flow in Grand Manan Channel, and a southerly movement off the east coast of Grand Manan Island.

This chapter includes a checklist of 220 bird species found in the Quoddy region.The coastal situation and varied habitats attract a large variety and quantity of birds to the Quoddy Region. Of most interest are the aquatic species of inshore marine habitats, the large numbers of phalaropes and gulls which congregate around Head Harbour Passage, and certain pelagic birds of the Grand Manan Channel. Also offering ample opportunities for study are shorebirds, of which the wintering Purple Sandpipers are most significant, and many terrestrial species that frequent coastal habitats.
The birds most poorly represented in the Quoddy Region are the dabbling ducks, rails, and other species of freshwater marshes which can be studied just outside the region at Moosehorn National Wildlife Refuge in Maine.
Despite many interesting features there has been relatively little systematic study of the avifauna of this region. With a few exceptions, the description that follows results from preliminary, restricted studies and from the casual observations of birdwatchers. inventory; Quoddy; habitats; phalaropes; gulls; seabirds; shorebirds; fauna; vertebrates; birds

Previous field manipulations with the predatory polychaete Nereis virens have indicated the existence of a 3-level interactive system within the infauna in Maine, USA (N. virens-Corophium volutator-other infauna). The purpose of this investigation, carried out in 1980, was to test the hypothesis that the addition of N. virens to a community where the intermediate predator/disturber C. volutator is absent should cause infaunal densities to decrease. Experimental results did not support this hypothesis. benthic; Gulf of Maine; annelids; invertebrates; ecology; faunaCook, R. H. (1988). "Salmon aquaculture in the Bay of Fundy: A quiet success."

The development of salmon Salmo salar aquaculture in the Bay of Fundy has been essentially a "grass-roots" movement. Production and good husbandry have been the goals and progress has not been measured on the number of sites approved or the magnitude of capital investment. Extreme precautions have been taken to monitor, screen, control and eradicate, when necessary, diseased fish within the system. These and many other factors have brought the essential elements together for a major salmon aquaculture industry and have given the New Brunswick salmon farmers a firm foundation. The purpose of this overview is to provide a perspective, from one who was there at the beginning, on this quiet success of Atlantic salmon aquaculture development in the Bay of Fundy. salmon; aquaculture; Fundy; fish; fauna; vertebratesCopeland, G.

The following represents the introduction: Upon my arrival at the Biological Station at Saint Andrews in July, 1910, Professor Penhallow asked me to investigate the waters of Passamaquoddy Bay and its neighbouring waters and rivers. This was to be undertaken from two standpoints; firstly, for its scientific and secondly its commercial aspect, it being the desire of the Department of Fisheries to ascertain whether or not there were suitable waters for oyster culture in the neighbourhood, and just what were the exact conditions in relation thereto. The work had more than a scientific interest for, incidently, we had the good fortune to see some beautiful scenery, and I would this were the place to describe the magnificent panorama of hill and vale, river and ocean and the gorgeous sunsets, but these must be left to another. Before I leave this heading I should like to thank my fellow workers for valuable assistance and especially Mr. A. B. Klugh, M.A., Mr. MacDonald, M.A., and Mr. Macdermot, as they were my most constant companions and I am deeply indebted to Prof. A.B. Macallum for having analyses done for me.

Diastylis sculpta was collected from shallow water (1-15 m) in Passamaquoddy Bay over a 26-month period. D. sculpta produces a rapidly growing and developing summer generation between two successive winter generations. The overwintering generation releases young in mid-July and late August. The summer generation releases young in November. The mean fecundity of the summer-gravid females (78.4) is much greater than the mean fecundity (20.0) of the fall-gravid females.

The distribution of each species is discussed and compared with previous findings.crustaceans; Northwest Atlantic; distribution; invertebrates; faunaCorey, S. (1981). "The life history of Crangon septemspinosa Say (Decapoda, Caridea) in the shallow sublittoral area of Passamaquoddy Bay, New Brunswick, Canada." Crustaceana 41(1): 21.
Crangon septemspinosa Say, 1818, the sand shrimp, inhabits coastal and estuarine waters from New Foundland to eastern Florida in depths of 0 to 450 m. The sand shrimps form an important part of the diet of many commercially and non-commercially important fish. The life history of C. septemspinosa has been described in several parts of its geographical range: Delaware Bay; Georges Bank; Lamoine, Maine. These studies have illustrated that many of the aspects of the life history of the sand shrimp vary greatly within its range. The waters of Passamaquoddy Bay are boreo-arctic in nature and thus C. septemspinosa may be near the extreme of its thermal range. This study forms an integral part of a larger ongoing project in which seasonal ecological aspects of the trophic interrelationships of a very shallow water sublittoral region are being investigated. shrimp; crustaceans; fisheries; Passamaquoddy; Quoddy; ecology; feeding; food web; life history; distribution; invertebrates; shellfish; faunaCorey, S.

No abstract was provided. From the introduction to Chapter 12:Zooplankton consists of the drifting animals of the sea. Weak locomotor capabilities cause these animals to be at the mercy of currents as they are unable to swim against them. Zooplankton can be categorized or subdivided according to duration of time spent as a zooplankton and size. Those remaining zooplankton for the entire life cycle are holoplankton, e.g. euphausiids and chaetognaths: meroplankton are plankton for only part of their life cycle, e.g. larvae of benthic invertebrates such as crabs and barnacles. Microzooplankton are those less than 1 mm and macrozooplankton those more than 1 mm in size. The latter classification is arbitrary and should be used cautiously. For example, some copepods would be considered microzooplankton as larvae but macrozooplankton as adults.
Chapter 13 deals with microzooplankton and copepods. This chapter is about holoplankton of which adults are usually greater than 5 mm. Included are chaetognaths, pteropods, ctenophores, cnidarians, euphausiids, and amphipods, and also benthic species which undergo a diurnal vertical migration and hence become members of the zooplankton community at night (mysids and cumaceans). (Paragraph on geography deleted)
Both qualitatively and quantitatively, the zooplankton of Passamaquoddy Bay is far less rich than that of the adjacent Bay of Fundy. The variety and quantity, especially of the larger zooplankton, decreases drastically from the Bay of Fundy into the Passages and is generally very poor in the inner portions of Passamaquoddy Bay. None of the holozooplankton listed above form endemic populations within the Quoddy Region. Specimens occurring in this area are part of much larger populations in the Bay of Fundy. The pelagic amphipods, pteropods, and ctenophores are not endemic to the Bay of Fundy and probably originate in the Scotian shelf and/or the Gulf of Maine. As a result, the relative abundance of these taxa varies greatly in time and space, especially in the Quoddy Region. The zooplankton in Passamaquoddy Bay and the Passages is most diverse and abundant in summer, less so in fall and winter, and least diverse and abundant in the spring (Legare and Maclellan 1960).
Other taxa frequently occurring in the zooplankton such as mysids, cumaceans, and decapods inhabit the Quoddy Region throughout the year. The jellyfish, Aurelia aurita, occurs seasonally. The pelagic polychaete, Tomopteris helgolandica occurs spasmodically and is most common during winter. Table 1 provides a brief, generalized summary of the larger zooplankton of the Quoddy Region, their respective habitats, relative depths, and seasonal abundance.zooplankton; Quoddy; fauna; inventory; copepods; benthic; distribution; invertebrates; habitats

Diastylis quadrispinosa inhabiting depths of 5-60 m in Passamaquoddy Bay breeds during late fall. Gravid females overwinter and release young during April to about mid-May. The life span is 5-6 months for males and 12-13 months for females.

Three mysids, Erythrops erythropthalma, Mysis stenolepis, and Neomysis americana occurred in the zooplankton of the Bay of Fundy and adjacent waters from 1973 through 1981. Erythrops erythropthalma occurred in low numbers in scattered areas, such as the mouth of Passamaquoddy Bay, Grand Manan Channel, the coast of Maine, and off St. Mary's Bay and southwest Nova Scotia. Mysis stenolepis was taken rarely and only in the shallower stations near the coast and in the inner Bay of Fundy. Neomysis americana was the most abundant mysid and the most widespread in its distribution. Populations were found at the head of the Bay of Fundy and in St. Mary's Bay. Seasonally, N. americana was least abundant in the spring, with numbers and area of distribution increasing in the summer and fall. crustaceans; zooplankton; fauna; distribution; Fundy; invertebratesCorey, S.

Three species of alcids-the razorbill Alca torda, the common puffin Fratercula arctica, and the black guillemot Cepphus grylle-reach the southern limit of their western Atlantic breeding range on the Maine coast. The presence of these species lends variety and excitement to the birdlife along the Maine coast. The common murre, Uria aalge, may possibly nest as far south as Maine.The history and current status of alcids nesting in Maine is reviewed. Razorbills and puffins are found on only two islands-Matinicus Rock and Machias Seal Island, the latter claimed by both the United States and Canada. Guillemots nest in substantial numbers along the coast.

From the introduction: During the month of August, 1914, the writer, under the direction of Dr. J.W. Mavor, and with his constant and active assistance, undertook to make a series of hydrographic observations in Passamaquoddy Bay and the St. Croix River. The object of this work was to obtain as much information as possible not only about the actual temperatures and densities of the water, but also about the nature of the currents of warm and cold water, how these are affected by this tides, etc. Such observations, besides being of importance and interest in themselves, are valuable on account of their bearing upon the haunts and habits of fish frequenting the waters studied, or passing through these waters in their migrations.hydrography; St. Croix; Passamaquoddy; circulation; oceanography; Quoddy; currents; temperatureCraigie, E.

From the introduction: During the summer of 1914 a hydrographic section of the Bay of Fundy was made, a report of which appeared in the Contributionsto Canadian Biology, 1914-1915. At the beginning of July, 1915, it was suggested that a considerable amount of dredging should be done with a view to working out the fauna of the Bay of Fundy, and the opportunity was taken to combine with this work a repetition of the hydrographic observations made in the previous year and to extend them over the greater part of the Bay. It was thus possible to collect sufficient data to give a general idea of the conditions existing in the water of this important and interesting region. hydrography; Fundy; oceanographyCummings, L.

R. (1984). Zooplankton studies in the upper Bay of Fundy since 1976, Can. Tech. Rept. Fish. Aquat. Sci. (No. 1256).
Extensive collections of zooplankton have been made in the Bay of Fundy in association with larval fish studies. Within the upper portions of the Bay of Fundy system, collections have been made with a variety of gear, for several months during the year, utilizing sequential time-series sampling over whole tidal cycles and general surveys. Zooplankton diversity declines with distance up the Bay toward the inner reaches. Abundance and biomass decline to a minimum in Chignecto Bay and Minas Basin where suspended sediment levels are <50 mg L-1, but rise dramatically in extremely turbid waters (>500 mg L-l). The zooplankton of inner waters is dominated by small estuarine species such as Eurytemora herdmani and Acartia tonsa. High biomass in extremely turbid waters suggests the plankton food web is detritus-based. Visual feeders are absent and vertical movements eliminated, except in the clearer waters of Chignecto Bay and Minas Basin. Specific studies of Eurytemora herdmani and Neomysis americana indicate high production in the most turbid waters, and both species are utilized extensively by fish. In moderately turbid areas fish feed primarily on benthic organisms.

The status of the southwest New Brunswick-Grand Manan scallop stock in 1983 was assessed on the basis of logged catch and effort records from the commercial fishery and the age-frequency distribution from a research survey cruise.The number of licenses in this fishery has remained stable at about 275 since 1981 but, according to log records, total days-fished has declined by a half. Although total landings has also declined by half, the CPUE has only declined marginally, from 4.53 kg/hm in 1981 to 3.55 kg/hm in 1983. Model age-groups of recruited scallops were seven and eight years, reflecting the dominant 1974 and 1975 year-classes which first entered this fishery during 1979. Catch and effort trends from log data for specific fishing sites suggest there may be movement of scallops from bed to bed.
In spite of high fishing pressure, large scallop year-classes appear in the Bay of Fundy in a cyclic fashion. It is speculated the appearance of these year-classes is caused by environmental factors. scallops; Grand Manan; Quoddy; fisheries; distribution; molluscs; invertebrates; fauna; shellfish; bivalves

Adult Placopecten magellanicus spawn between July and September in Passamaquoddy Bay, and larvae are present in the water column from July to October. Observations on spat settlement in collectors, however, indicate the major settlement takes place during a period of about 2 weeks; and this time of settlement varies from year to year, occurring from late August to October. Numbers of spat per collecting bag were relatively constant from year to year (X-200-400) but varied with depth. After settlement in September, spat reach a mean height of 5 millimeters (mm) by December and 40 mm by the next November in suspended culture. Natural bottom growth is slower. Depending on site, mean height ranges from 25-35 mm after the first summer of growth.

Larval herring samplings were carried out in the Bay of Fundy-Gulf of Maine area from September 1960 to June 1963. Plankton samples obtained confirm spawning areas off the southwest coast of Nova Scotia and on Georges Bank. Larvae were in greatest abundance in September and October in St. Mary Bay area; post-larvae were found in considerable numbers in spring. The estimated average seasonal larval mortality in autumn in the area was 99.53%. Growth was rapid initially for the autumn-hatched larvae; growth declined during winter. Growth-rate increased in spring, being higher than that of late fall and winter. There was evidence to suggest that the autumn-hatched larvae from southwest Nova Scotia are the major contributors to the herring stocks in the Fundy area. It is possible that Georges Bank spawnings contribute to the herring population in this area, although not, of course, to the same extent as does that from southwest Nova Scotia. reproduction; distribution; fish; herring; Fundy; Gulf of Maine; hydrography; growth rate; vertebrates; fauna; life history; oceanographyDas, N.

Initial growth rate for autumn-hatched herring larvae in the Bay of Fundy-Gulf of Maine area is about 2 mm per week. It gradually declines to less than 1 mm per week during the late autumn and winter months, and then increases geometrically in the spring and early summer to an average of 2.5 mm per week. herring; fish; Fundy; Gulf of Maine; growth rate; fauna; vertebratesDavidson, L.

Collections made during a period of seven and a half years (1924-1931) weekly at a station of 30 m depth in the St. Croix estuary and monthly at a station of 90 m depth in the outer bay show three dominant species. Thalassiosira Nordenskioldi dominates during spring at both stations, being definitely stenothermic, finding somewhat under 6° C. most favourable, and disappearing at that temperature, which is reached earlier in the estuarine station. Chaetoceros debilis dominates in June at that station. It is most abundant at 10-12° C., but occurs at lower as well as at higher temperatures up to the summer maximum of 15° C. Biddulphia aurita, an early spring littoral species, reaches its maximum at about 2° C., and disappears when the spring freshet takes place. The forms were arctic-neritic in spring (beginning with the melting of the snow), arctic and boreal in June and July, and temperate and oceanic in late summer and autumn.There is no apparent lack of nutrient salts, nitrates, phosphates and silica being reduced but never depleted. Light is an important factor, but its effect is not clearly distinguishable, the peak of diatom production being reached usually in June at the outer station and in late June or early July at the inner station, while July had the most effective light. Marked reduction in surface salinity from river discharge with consequent stability of the water precedes the spring maximum of phytoplankton, and to a less degree local rainfall of summer has a corresponding effect.diatoms; Passamaquoddy; distribution; phytoplankton; inventory; Quoddy; nutrients; temperature; flora; estuarine

It is estimated that tourists spent approximately $10.0 million in Charlotte County, New Brunswick, in 1973 and that $2.8 million of this was associated directly with shoreline use. Total tourist expenditures in the Bay of Fundy Region, for 1973, are estimated to be $24 million of which $13.9 million is directly attributable to the use of the coast. Approximately 25% of all travel accommodations along the coast of the Bay of Fundy are in the Passamaquoddy Bay region (Charlotte County, New Brunswick) and approximately 40% of total Bay of Fundy tourist expenditures are in coastal Charlotte County. There are, as well, unquantified recreational values of local residents using the coast. Possibly, angling in fresh water streams could be affected by an oil spill, particularly salmon angling. The striped bass fishery might also be affected. The extent of recreational boating is not known. There are boat clubs at St. Andrews, New Brunswick, Cornwallis and Digby, Nova Scotia.

Of a total population of approximately 25,000 in Charlotte County, New Brunswick, 2850 people or about 11% of the population are engaged directly in the fishing industry either as fishermen or employees of fish processing companies. The number of persons dependent upon the fishing industry would, of course, be several times as great. In regions such as Grand Manan and West Isles, virtually the whole economy depends upon this industry. In the entire Bay of Fundy, the fishing industry is somewhat less important with approximately 2% of the population employed directly in fishing industry. At the mouth of the Bay of Fundy (Charlotte County, Nova Scotia, and Digby and Yarmouth Counties, Nova Scotia), the fishing industry is of about the same relative importance as in Charlotte County with approximately 9% of the population deriving part or all of their income from fishing or working in fish processing plants. Along the coastal areas of the mouth of the Bay, virtually the entire economy is dependent upon the fishing industry as very little other industry exist. oil spills; Passamaquoddy; fisheries; Quoddy; Fundy; contaminants; pollution; industry; economicsDickerson, S. (1994). A method for the selection of ecological reserves in regions lacking well-developed ecological data, Master of the Philosophy of Human Ecology, College of the Atlantic.
This thesis presents a method for selecting ecological reserves for the conservation of biological diversity in regions which lack extensively developed ecological data. Such areas are generally distant from academic, research, and governmental institutions, yet draw the greatest interest of conservation biologists because the biota of the regions are often less impacted by human activities. The method defines the general goal of ecological reserves, states specific objectives, and describes nine strategies that may be used as surrogates for inadequate ecological data. The strategies, based on ecological concepts and information available in the subject region, include: 1) selection of an appropriate planning boundary, 2) evaluation of existing public lands, 3) inclusion of identified priority biological diversity sites, 4) representation of physical gradients, 5) inclusion of areas least-disrupted by human activities, 6) accommodation of the natural disturbance regime, 7) use of umbrella species, 8) reserve size, linkage, and buffer configuration, and 9) considerations to minimize the impact of global climate change. The ecological reserve recommendations that result from application of the method can be integrated with economic, cultural, and political interests of the subject region in a public process of comprehensive planning for the conservation of biological diversity.Application of the method is demonstrated in the Dennys River and Bay Watershed, located in eastern Maine. The first seven strategies were applied to delineate a preliminary set of ecological reserve areas. Application of the final two strategies were found to be more effective at a later stage in planning and implementation of the potential reserve system. Emerging technologies--geographical information systems (GIS), satellite imagery, and global positioning systems (GPS)--were used to inventory, develop, and analyze data, and display application results as illustrative maps. The results of this demonstration are discussed, and recommendations made for monitoring the effectiveness of the ecological reserve system at conserving biological diversity in the Dennys Watershed, if the system is implemented in the future. Such monitoring is essential to improve future selection and management of ecological reserves. Advisor: John Anderson. ecology; conservation; Cobscook; Quoddy; maps; GIS; Dennys River; inventory

Intertidal Bedrock Areas of High Species Diversity in Maine, and Their Relevance to the Critical Areas Program, Maine Critical Areas Program Planning Report (No. 55), Critical Areas Program, Natural Resource Planning Division, Maine State Planning Office.
Intertidal bedrock areas have a high species diversity when specific conditions are met. A relatively high energy level due to wave action and a heterogeneous substrate which contains tidepools and crevices in the lower intertidal zone are among the most important conditions determining the level of species diversity. A number of the species present in these high diversity areas are unusual and noteworthy. Brittlestars, sponges, sea spiders, and nudibranchs (shell-less gastropods) are examples of the fauna present.This report documents and describes areas of high species diversity at 18 intertidal bedrock sites. Also included (for the 12 sites which were field checked) are species lists which state the zone in which the species was found and the relative abundance of the species.
General information on marine invertebrates is provided. Abiotic and biotic factors as they pertain to the species in this habitat are discussed. Descriptions of the intertidal zones and the species which were present at the sites which were checked are included.
Criteria for determining significant sites are stated. It is recommended that additional sites be considered and that they be evaluated based on the criteria presented in this report.
Intertidal bedrock areas of high species diversity can be disturbed and/or destroyed by over-collecting and excessive foot traffic. Therefore, this report recommends that the 18 sites described here be evaluated for inclusion in the Register of Critical Areas. geology; intertidal; diversity; inventory; invertebrates; conservation; Gulf of Maine; bedrock; fauna; tide pools; rocky; habitats
Doucet, W. F. (1960). "Economic study of the herring fishery of Charlotte County, New Brunswick, 1956-1957." Journal of Fisheries Research Board of Canada 17(6): 815.
This report presents the results of an economic survey of the herring fishery of Charlotte County, New Brunswick, conducted in 1957 and 1958. It contains: (a) a detailed account of the capital investment and income position of the fishermen who were engaged in the herring fishery during the years 1956 and 1957; (b) some evaluation of the economic effects which the construction of hydro-electric power dams in Passamaquoddy Bay would have on the herring fishery of the area. Except for a small complement of men employed on purse seiners, draggers and a few other modernized fishing craft, the fishing activity of Charlotte County fishermen is largely confined to inshore operations. As a result, the primary fishing industry is not highly capitalized. Average net incomes are also low compared with those prevailing in other industries, even with those derived from a number of fisheries elsewhere in the Maritime Provinces. Incomes from the weir fishery are particularly uncertain, in view of the wide fluctuation in yearly catches and the high rigid operating costs. In contrast with weir fishing, purse seining has proven to be an efficient method of fishing in the region, and holds considerable promise for the improvement of earnings in the herring fishery.It is expected that the construction of the proposed power dams would add to the cost of maintaining and operating weirs in Passamaquoddy Bay, thereby reducing returns to owners and fishermen in this segment of the industry. In view of the low earnings now derived from weir fishing in certain sections of the area, it is likely that a number of weir owners would not continue to maintain their weir investments if the power dams were built. herring; fisheries; Passamaquoddy; Quoddy; tidal power; economics; fish; vertebrates; fauna

To predict possible effects of the proposed Passamaquoddy Tidal Power Project dams and gates on herring movement in and out of the Passamaquoddy Bay region, information was first needed on the swimming performance of the fish. Maximum and sustained swimming speed tests designed for this purpose indicated (1) that the maximum swimming speed for herring 60 to 219 mm. long ranged from 2.3 to 4.4 feet per second and (2) that the swimming endurance for herring exposed to currents of 1.2 to 3.2 feet per second ranged from 0 to 89 minutes. Considering the length of the passages into the bay, and considering that the speed of the currents within these is ordinarily too great for a herring to stem, movement could occur only by the fish being swept in and out passively. The construction of filling gates that operate at flood tide and emptying gates that operate at ebb tide would, therefore not appear to hinder herring migration.

A survey of the scallop fishery in the Passamaquoddy Bay area of Maine was made as part of a larger investigation into the past, present, and future status of fish and shellfish species that might be affected by the construction of a proposed tidal power plant in that region. The past record of commercial production, and the present abundance level and environmental conditions are described, together with deductions as to the effects on the scallop fishery of predicted oceanographic changes. scallops; Passamaquoddy; Quoddy; molluscs; fisheries; tidal power; invertebrates; fauna; invertebrates; inventory; shellfish; bivalvesDuncan, C. D. (1996). "The migration of red-necked phalaropes." Birding (December 1996): 482.
No abstract available. Summary: This article provides some background biological information regarding the feeding and migration habits of the red-necked phalarope. Hundreds of thousands of red-necked phalaropes used the Cobscook Bay region during fall migration as a resting and feeding area. In the 1980's the author noticed a drastic decline in the number of birds returning to these areas and proposes three theories for this crash: 1) The crash is prey-related, perhaps due to a decline in plankton. 2) The crash is unrelated to conditions in the Quoddy region, but linked to other areas along their migratory route. 3) The fall staging concentration has not collapsed, but has simply shifted to less visible areas. The author explores each of these theories but does not present conclusive evidence supporting any one. Cobscook; Quoddy; feeding; migration; shorebirds; birds; vertebrates; faunaE.G.&G (1973).

The earthquake activity of Maine appears to be similar to that of other parts of the Appalachian province. The recent seismicity is generally occurring in the same areas which were active historically. Eastern, central, coastal, and western Maine have most of the earthquakes and are the areas where the largest known events have occurred. Return times estimated from recent instrumental data for earthquakes of magnitudes 5, 6, and 7 are about 50 years, 350 years, and 2600 years, respectively, in the state. While the earthquakes probably are caused by reactivations of old zones of weakness in the present plate tectonic stress field, no individual faults or other structural features have been confirmed to be seismically active.geology; seismicityEmerson, C. W. and J. C. Roff (1987). "Implications of fecal pellet size and zooplankton behaviour to estimates of pelagic-benthic carbon flux." Mar. Ecol. Prog. Ser. 35: 251.
Numbers, volumes and carbon content of fecal pellets collected by sediment traps and bottle casts were measured with an image analysis system, from samples collected in the lower Bay of Fundy, Atlantic Canada. Analysis of sinking, resuspension and biodegradation rates indicated that small fecal pellets must be heavily grazed within the water column. Measurement of rates of coprophagy and vertical distribution of pellets without peritrophic membranes may lead to estimates of resuspension. Differences in size-frequency spectra of pellets collected in 5 h and 24 h sediment trap developments indicated that large fecal pellets which reach the benthos are produced primarily by migratory copepods and euphausids. The effects of diel vertical migration may bias estimates of pellet carbon flux made from short sediment-trap deployments.

Canadian Journal of Zoology 69(2): 449.
The feeding mechanism of the euryaline basket star Gorgonocephalus arcticus from the Bay of Fundy is described from in situ and laboratory observations of feeding behaviour, analysis of gut contents, and examination of the anatomy and microanatomy of the arms. G. arcticus, which is abundant in areas of moderate to strong current flow, is a fortuitous predatory suspension feeder, coiling and bending its arms to capture prey. The predominant food item in the gut was the euphausiacean Meganyctiphanes norvegica. Food capture by arm bending and coiling is assisted by the adherence of food to rings of sharp hooks on the arm. The role of the tube feet in food capture appears to be minor. Owing to the form of the feeding fan, the animal is adapted for life in strong currents. There is morphological evidence for the presence of mutable collagenous tissues which may be important in maintaining the feeding fan. echinoderms; Fundy; feeding; invertebrates; faunaFamous, N. and M.

The American Eider (Somateria mollissima dresseri) in Maine and its Relevance to the Critical Areas Program, Maine Critical Areas Program Planning Report (No. 27), Critical Areas Program, Natural Resource Planning Division, Maine State Planning Office.
The American eider, Maine's only breeding sea duck, is known to have nested on 215 coastal islands of the State in 1976. In Maine, eiders seem to prefer to nest on relatively small, uninhabited islands. The numbers of eiders on the Maine coast have fluctuated greatly since colonial days. Eider populations declined in the late l9th and early 20th century due, presumably, to egg collecting and overshooting at concentration points, especially on breeding islands in the spring. Early in this century, protective policies were implemented. As a result, the population began to increase and this trend has continued to the present. The 1976 breeding population is estimated to be a minimum of 20,000 pairs.The major threat to breeding populations of eiders is human disturbance during the nesting season. The production of young in a disturbed colony can be seriously diminished for the breeding season. Other limiting factors include the presence of either predatory birds and mammals or domestic animals.
Criteria for determining significant nesting areas for the eider duck in Maine are defined and a historical review of eider duck nesting on the Maine coast is presented. In 1976, the birds nested on at least 215 islands in Maine of which 49 were of significance for eiders. These significant areas provided breeding habitat for at least 60 percent of Maine's 1976 eider population. It is suggested that these nesting areas be maintained in their present condition and that human disturbance on such islands be restricted during the nesting season (1 May - 15 July). ducks; reproduction; eiders; fauna; population; life history; vertebrates; habitats; birds

Solvent extraction of C. frondosa, collected in Passamaquoddy Bay, has afforded a variety of natural products. Silica gel chromatography of the chloroform extract has provided an abundance of sterol glycosides, sterol sulfates and free sterols. By methanol extraction, a mixture of triterpenoid saponins has been obtained. Partial hydrolysis of this material has yielded several monosaccharides, aglycones and one aglycone with a xylose unit attached. A new triterpenoid lactone has been isolated and its structure is proposed. echinoderms; Passamaquoddy; Quoddy; invertebrates; faunaFink, L. K., Jr., D. M. Pope, et al. (1976). Heavy metal levels in suspended particulates, biota and sediments of the St. Croix estuary in Maine, Land and Water Resources Institute, University of Maine, OWRT Project No. B-010-ME, University of Maine.
This report presents the results of an investigation to determine the impact of a pulp and paper mill effluent on various environmental compartments of the St. Croix River and Estuary System. The data include 7,940 analyses for ten metals (Ag, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn) in samples of suspended particulates in water, biota, and sediments from thirty-three sites located along the freshwater and marine sections of the St. Croix River.A fact that emerges from this report is that, despite the relatively small scale of industrial activities in the St. Croix River, the accumulation of heavy metals, which are direct consequences of anthropogenic activity, in the biota and sediment is equivalent to the levels reported from areas characterized by large-scale industrialization. The main distinction between the two scales of activity seems to be more one of the areal extent of the impact and not the degree. In general, the elevated levels are restricted in areal extent in the St. Croix River and are not observed throughout the system.
The results of this study have provided a basis for evaluating water quality assessment techniques for heavy metals. Increased heavy metal contributions were indicated, not by analyses of the water compartment, but by analyses of the biota and sediment compartments, thereby strongly suggesting a revised approach to water quality assessment and monitoring techniques. The impact-assessment techniques also demonstrate the significance of using sediment cores to increase the understanding of heavy metal transport mechanisms and pathways among compartments in estuaries. The results from sediment cores are highly reproducible and afford a means for a) assessing factors influencing metal accumulation levels, b) comparing variable areas, c) establishing background levels, and d) defining reference sections for assessing future changes in heavy metal contributions from anthropogenic activities. These conclusions are consistent with theoretical predictions based on the carrier-reservoir equilibrium model proposed as a working concept for this study.
The sequestering of most of the anthropogenic contributions of heavy metals within the estuarine environmental compartments is consistent with findings of other studies and suggests that additional efforts now be directed toward determining the potential for back-transport mechanisms from metal-laden sediments which may result even after toxic effluent treatment schedules are realized. metals; Passamaquoddy; Quoddy; contaminants; pollution; sediments; estuarine; St. Croix; effluent; industry

No abstract available. Introduction: Although Oithona similis, one of the two microcalanids found breeding in the Gulf of Maine, is small in size, the relative abundance of larvae indicates that at times it forms a significant factor in the natural economy of the region. It is particularly favorable for quantitative study because adults, larvae, and egg cases all appear to be sampled representatively with fine nets (No. 10 silk) and the pump.This paper forms the third of a series on the biology of zooplankton species in the Gulf of Maine and Bay of Fundy with special reference to production and dispersal, and is based on material obtained between July 28, 1931 and September 29, 1932, in the course of investigations carried on for the International Passamaquodddy Fisheries Commission.

Fish, C. J. (1955). "Observations on the biology of Microsetella norvegica." Papers in Marine Biology and Oceanography Supplement to Volume 3 (Deep Sea Research): 242.
No abstract is available. Summary: Microstella norvegica is one of two microcopepod species which appear significant in the natural economy of certain western Atlantic boreal waters. During the winter months it extends its range southward at least as far as the latitude of Chesapeake Bay. North of Cape Cod in the Gulf of Maine region it is widespread with a tendency to form concentrations of limited area.Propagation in 1932 began in March in the outer area between Georges Bank and Cape Cod and gradually expanded as the season progressed until it reached a peak in the Gulf along a band seaward of the 100 meter curve from Casco Bay to the Bay of Fundy.
There is evidence of three and possibly four generations between March and September. As in other endemic pelagic species there was a progressive delay to the eastward in the time of spawning, but unlike most of these Microstella was found propagating successfullly at low summer temperatures averaging 11-13.5 degrees celcius, in the turbulent eastern (Frenchman's Bay) area.

Fish, C. J. and M. W. Johnson (1937). "The biology of the zooplankton population in the Bay of Fundy and Gulf of Maine with special reference to production and distribution." Journal of Biological Board of Canada 3: 189.
Analyses in the Gulf of Maine and Bay of Fundy show the zooplankton population to be dominated by a relatively few species of boreal endemic crustaceans. Calanus finmarchicus, the most abundant form, averaged 39.9 per cent by number in the total region during the period, April to September in 1932, and 35.5 per cent for the year in the Bay of Fundy. Fluctuations in the volume of zooplankton reflect to a large extent numerical changes in the stock of this species. The vernal rise in 1932 occurred following propagation of Calanus, and the rapid downward trend in June coincided with the critical period of maturation and subsequent mortality of adults after spawning.Due to differences in the time of spawning in different parts of the region, two, and in some cases three, breeding stocks of boreal plankton animals can usually be distinguished. The distinct spawning periods are continued in subsequent generations that year no matter where distributed.
Productivity was found to be closely correlated with temperature and stability of the water mass, and dispersal with the nontidal circulation in the region. The vernal crop of boreal plankton species appears to be derived largely from adults maturing in the western or outer gulf. With the advance of the season the center of production moves to the eastern basin. The turbulent New Brunswick-eastern Maine coastal zone as far west as Mount Desert is relatively unproductive, and characterized by small zooplankton volumes.

Annual cycles of plasma antifreeze peptide levels were compared in winter flounder Pseudopleuronectes americanus from 3 areas: Conception Bay, Newfoundland; Passamaquoddy Bay, New Brunswick; and Shinnecock Bay, Long Island, New York. Winter flounder from the most southerly population, Shinnecock Bay, initiated antifreeze peptide production at the same time of year (Nov) as did flounder from the most northern population (Newfoundland). Flounder from a geographically intermediate population, Passamaquoddy Bay, produced antifreeze peptides approximately 2 mo later (Jan). It is hypothesized that the time of antifreeze production is a genetically determined population characteristic which reflects the earliest data that antifreeze peptides would be essential to their survival.

Temperature and salinity data were collected in a series of 43 cruises in the Quoddy Region during 1957 and 1958. Spatial and temporal distributions of temperature and salinity are given and departures from the normal noted. Between high water and low water differences in temperature and salinity were slight but complex in the Outer Quoddy Region. Near the heads of the estuaries the variations were more marked and corresponded with the phase of the tide. Flushing times in Passamaquoddy Bay vary from 8 to 17 days depending on the season. In the Magaguadavic and St. Croix estuaries, flushing times were found to be 2 and 6-7 days, respectively. Chapter 1.

Early in 1957 the Canadian Hydrographic Service accepted a request from the Fisheries Research Board of Canada to cooperate with its Atlantic Oceanographic Group in conducting physical oceanographic studies in Passamaquoddy Bay and the Bay of Fundy. These studies form part of a program to determine the physical conditions contributing to the existence of commercial fisheries, particularly the herring fishery, in Passamaquoddy Bay. It is further hoped they will make it possible to predict the effect on these physical conditions, and hence on the fisheries, of damming the entrances to the bay to construct a tidal power plant.The immediate concern of the Atlantic Oceanographic Group and the Canadian Hydrographic Service was to determine the tidal and non-tidal water movements in Passamaquoddy Bay and its approaches, and to measure the physical properties such as temperature, density, and chemical composition of the water at various depths and locations. From this information it is hoped to obtain better knowledge of such matters as general circulation and mixing of different water types in Passamaquoddy Bay. Marine biologists will then carry the study further by attempting to interpret the results in terms of transport of food, movements of fish, and any effects on the environment of the fish. All information gathered and conclusions drawn by the various agencies will later be embodied in a report by the International Passamaquoddy Fisheries Board to the International Joint Commission.

Currents were measured at sixty stations in Passamaquoddy Bay and the Bay of Fundy during the summer of 1957 and 1958 (Figure 1). This project was carried out jointly by the Canadian Hydrographic Service of the Department of Mines and Technical Surveys, and the Atlantic Oceanographic Group of the Fisheries Research Board of Canada, and an interim report was prepared (Forrester, 1958). The program, aimed at determining the tidal and non-tidal water movements in Passamaquoddy Bay, in its approaches, and in part of the Bay of Fundy, constituted an important element in the oceanographic studies carried out for the International Passamaquoddy Fisheries Board (Hart and McKernan, 1960). Field surveys were conducted during the summer months of 1957 and 1958 using two vessels, the 84-foot Harengus belonging to the Fisheries Research Board, and the 49-foot Mercury, a chartered fishing boat. During the early part of the 1957 season, observations were made from a drilling barge employed by the United States Corps of Engineers to take bottom core samples in the entrances to Passamaquoddy Bay. Most of the data were gathered with current meters suspended from an anchored ship and read at half-hour intervals. At each station, water samples and temperatures were taken at various depths using reversing water bottles and bathythermographs.None of the current-measuring equipment was ideal for the conditions encountered. The Ekman current meter was used most extensively and was supplemented by the Chesapeake Bay Institute drag and the Gurley current meter. The Ekman propeller releasing and locking device did not function properly at the high velocities encountered. The Gurley meter registered unreliable velocities in rough seas, and the drag assumed exaggerated wire angles at high velocities. Only by using the three methods and balancing the flaws of one against the advantages of another were reasonably reliable results obtained.
Tides in the Bay of Fundy are characterized by a predominant semidiurnal component. For this reason, some stations were observed over only a 13-hour period, ignoring longer-period components, to enable more stations to be occupied. However, most of the stations were observed over a 25-hour period. Three key stations were occupied for 72 hours to strengthen the accuracy of the results.
In the mentioned interim report tidal stream and residual current information obtained at each anchor station was presented in both tabular form and in the form of synoptic charts showing the tidal stream at hourly intervals with reference to time of high water at Saint John, New Brunswick. Tidal stream velocities and directions were shown for three depths at each station. Velocities were adjusted proportionately to a range of tide of 21 feet at Saint John. Velocity and direction of the residual current at each of the three depths were shown. The report was essentially an analysis of data and no conclusions were drawn.
Results indicate that the tidal currents vary markedly throughout the region. Maximum recorded speeds were found in Letite Passage where mean maximum speeds reached 8 feet per second (4.8 knots). In Passamaquoddy Bay, speeds were mostly less than 1 foot per second. Near the mouth of Cobscook Bay mean maximum speeds were 5 feet per second. In the outside area, mean maximum speeds seldom exceeded 5 feet per second. Currents were usually maximum in the surface layer and decreased slowly with depth. Residual flows were mostly less than 2 miles (nautical) per day in Passamaquoddy Bay, Cobscook Bay and the approaches. In the Bay of Fundy, residual flows were variable and in some areas were as much as 10 miles per day. currents; Passamaquoddy; Quoddy; Cobscook; Fundy; oceanography; hydrography; circulation; tides; temperature

If tidal range in Cobscook Bay and tributary bays is modified to run between present half tide level to 6 feet above that (a regime compatible with tidal power generation), the water would be warmer in summer and conditions for some types of fisheries production would be better than they are at present. Well managed intertidal areas may be capable of producing 135 thousand bushels of soft shell clams annually worth $1.5 million. Subtidal area could produce 193 thousand bushels of oysters worth $5.8 million. Alewife and Atlantic salmon runs could produce $41,000 and $12,500 worth of fish each year. Rainbow trout could be cultured in net pens with production of 6 million pounds each year worth $10.4 million if present sources of fish food were utilized. The area has a capacity for producing 35 million pounds of trout worth $57 million if underutilized and wasted sources of fish protein were incorporated as fish food.

Wetland trends for selected areas of the Cobscook Bay/St. Croix River estuary of the Gulf of Maine, U.S. Fish and Wildlife Service, Hadley, MA. Ecological Services (No. R5-94/3).
Conclusion: The study area has approximately 14.2% of its land mass covered by wetlands. Wetlands totaling 20,805 acres (in the mid-1980s) were identified in the study area by the Service's National Wetland Inventory. Palustrine wetland is the dominant type, representing 56.7% of the wetlands in the study area.Between the mid-1970's and the mid-1980's, the study area lost about 77 acres of vegetated wetlands, all of which were converted to nonvegetated wetlands or deepwater habitats. No changes were observed in estuarine wetlands during the study period. Pond construction added about 88 acres of palustrine nonvegetated wetlands; however, there were 20 acres of pond succession to vegetated wetland, reducing the net gain in ponds to 68 acres. Beaver converted over 58% of the palustrine vegetated wetlands that changed to nonvegetated wetlands, and were the cause of 54% of all changes recorded in the study area.
While this report documents recent trends in the study area's wetlands, it does not address changes in the quality of remaining wetlands. As development increases, the quality of wetlands can be expected to deteriorate due to agricultural runoff, increased sedimentation, groundwater withdrawals, increased water pollution, and other factors, unless adequate safeguards are taken to protect not only the existence of wetlands, but their quality.wetlands; Cobscook; Quoddy; St. Croix; estuarine; distribution; inventory; Passamaquoddy

The present report contains the conclusions reached by the investigators appointed by the International Passamaquoddy Fisheries Commission to determine as accurately as possible the effect of the proposed tidal power dams on the fisheries of the Passamaquoddy Region and adjacent areas. In as much as the herring (sardine) fishery forms by far the most important industry in the region under consideration, and since the resource of the commission were limited, this report is confined to this species. The investigators, have reported that they anticipate that construction of the proposed dams would practically extinguish the herring fishery inside the dams; that the fishery in the adjacent area outside the dams (Quoddy Area) would be affected to an unknown degree, either adversely or favorably; and that there appears little probability of the dams affecting the fishery along the coast of Maine or even seriously of Grand Manan. tidal power; Passamaquoddy; Cobscook; fisheries; herring; Quoddy; fauna; vertebratesFowler, J.

No abstract available. From the introduction:"On June 9, 1900, the writer arrived at the Biological Laboratory, at St. Andrews, and devoted his time till August 18, to the study of the flora in the neighbourhood, and to the collection of herbarium specimens. The special object of his visit was to collect and study the marine algae that might be found in that part of the Bay of Fundy. At the time of his arrival the retreating tide had left the rugged shore bare for a considerable distance, and the rocks, covered with a dense growth of rock-weed (Fucus) presented an attractive field for exploration. After spending a couple of days among the slippery rocks and mud, he discovered that very few species of algae could be secured, and only those of the most hardy species. The rugged character of the shores, formed by the waves and tides from the red sandstone in some localities, and from volcanic rock in others, renders it impossible to travel along the beach any considerable distance in search of specimens. The aid of a boat is indispensable to the collector who wishes to extend his researches beyond the immediate neighbourhood of the station; but unfortunately the writer was precluded from more extended investigations. Disappointed at the small number of species where the prospects seemed so bright, he endeavoured to discover the reasons of their paucity, and is of the opinion that the following facts explain the phenomenon:?
l. The great tides of the Bay of Fundy produce currents which sweep away all plants not firmly anchored to the rocks. The fucaceae, possessed of tough and flexible stems, and attached to the rocks by holdfasts that cannot be separated from them by any force tugging at the stems and branches, are naturally adapted to resist the action of waves and currents, while other more delicate species are swept away and carried out to sea or thrown up on the rocky shores.
2. At low water, a large extent of shore is left bare, and the algae attached to the rocks are exposed for several hours every day to the warm winds and drying power of the summer sun. All plants unable to endure this ordeal must give place to the hardier species. The delicate forms that inhabit the pools or marshy shores are consequently unknown.
3. The great rise and fall of the tides stir up the waters of the bay to a great depth and as no broad areas of sand are exposed to the sun's rays to absorb heat and impart it to the waters that cover them at the return of the tide, these waters are always cold, hence only algae capable of flourishing in the cold waters are adapted to these rugged shores.
The combination of these factors constitutes an environment which is fatal to all but the most hardy species of littoral algae. All delicate forms must betake themselves to retired creeks and sheltered inlets where many of them may doubtless be found; but they can only be reached by the collector who is fortunate enough to enjoy the advantage of appropriate transit by water.
Having failed, owing to the causes mentioned above, and the lack of necessary facilities for identifying species, to secure the number of marine plants anticipated, the collector immediately turned to the streets and fields of the town and its neighbourhood which promised a more abundant harvest." flora; Passamaquoddy; Quoddy; algae; seaweed; intertidal; inventory; tides; rocky
Frazer, C., J. R. Longcore, et al. (1990). "Habitat use by postfledging American black ducks in Maine and New Brunswick." Journal of Wildlife Management 54(3): 451.
We examined habitat use by 112 postfledging American black ducks (Anas rubripes) in eastern Maine and southwestern New Brunswick from September through early December of 1985, 1986, and 1987. Ducks were captured on Moosehorn National Wildlife Refuge (NWR), Maine. Palustrine Emergent Wetland was the most preferred habitat type. Riverine habitats were avoided in September, but were used more than, or in proportion to, their availability in November as ice formed on lentic habitats. Black ducks used a greater variety of habitat types during the day than at night, when ducks used mostly large (> 30 ha) Emergent Wetland marshes. Managed impoundments of Moosehorn NWR were the most used wetlands (66% of all diurnal, 90% of all nocturnal locations). For black duck management, we proposed maintaining large (30-50 ha) marshes containing dense emergent vegetation that are located near a complex of diverse wetland types. habitats; ducks; Gulf of Maine; wetlands; birds; fauna; vertebrates; distribution; Moosehorn NWR; Cobscook; QuoddyFrazer, C., J. R. Longcore, et al. (1990). "Home range and movements of postfledging American black ducks in eastern Maine." Canadian Journal of Zoology 68(6): 1288.
We monitored the movements of 97 female and 15 male juvenile American black ducks (Anas rubripes) in the vicinity of Moosehorn National Wildlife Refuge in eastern Maine and southwestern New Brunswick from September through mid-December, 1985-1987. Movements were described by estimating home ranges and radial movements from the primary roost marsh. Overall home range sizes averaged 4987 ha (range 54-28,070 ha), and maximum distances moved from the roost averaged 9.9 km (range 0.9-42.8 km). Home ranges were linear (linearity index 2.8), and home range area and distance of movements from the roost both increased monthly. Ducks that used >15% riverine habitat had larger home ranges and moved greater distances from the roost than ducks using <15% riverine wetlands. Movements did not differ between ducks usually alone and those usually in flocks. Juvenile black ducks moved in small flocks and were often alone (34% of 355 observations). Most ducks showed fidelity to one roost-marsh complex from September until migration in late November. Daily and seasonal movement patterns were similar to those predicted for refuging systems. habitats; ducks; Moosehorn NWR; Cobscook; Quoddy; distribution; wetlands; birds; vertebrates; faunaFritz, C.

From the introduction:If a bottle of water be drawn from the sea and examined with the naked eye nothing presents itself but the clear, sparkling liquid; but if this same sample be centrifuged for half an hour and the residue examined under the microscope, it will be found that many organisms of unparalleled beauty have been extracted. Chief among these are the diatoms, unicellular plants, exquisite in beauty of symmetry and design. The object of the investigations recorded in the following pages is to add some facts to the present knowledge of these interesting forms.
Collections of material were made throughout the year from October 1916 to October 1917 at various points in Passamaquoddy Bay and the adjoining waters of the the Bay of Fundy. Careful examination of these has revealed the presence of eighty-two species, representative of twenty-six genera. Material collected during the different months was found to vary greatly. Attention was, therefore, given to the seasonal distribution and relative abundance of the many forms. Ordinary tows were taken at the surface and at a depth of from five to six metres, but during the summer of 1917, a series of samples was drawn from certain stations at various definitely recorded depths, and the contents examined in order to ascertain the bathymetric range of species.
Eighty-two species were found, and figures are furnished of those which are rare, or, owing to their similarity, difficult to classify. The system of classification used is that introduced by W. L. Smith and followed by Van Heurck (1) and by the Challenger Report (3)-.
I desire to take this opportunity of expressing my thanks to Dr. A. Willey, under whose guidance the problem was commenced; to Dr. A. G. Huntsman, Director of the Biological station, and to his assistants, for their careful attention to the collection of material and to Professor C. M.

A population of Mytilus edulis is described which is numerically dominated by young (< 2 yr old) individuals. Growth within this population is indeterminate, i.e. no maximum shell length is attained throughout the realized life span. Predation pressure, principally by Carcinus maenas and Asterias vulgaris, results in a population mortality rate of 42% in a 6 month period and also probably prevents growth from being determinate. The partitioning of organic matter between shell and body growth is discussed in connection with the cycling of energy within the ecosystem of the rocky intertidal zone. mussels; intertidal; ecology; Quoddy; predation; growth rate; invertebrates; shellfish; fauna; life history; molluscs; bivalves; rockyGardner, J.

The rocky shore intertidal population of the periwinkle, Littorina littorea, at Welchs Cove, Bay of Fundy, is composed of three or four cohorts depending upon the time of sampling as related to the time of recruitment. Cohort growth was relatively constant with time as a result of a comparatively short life span (3-4 years). Daily growth rate of shell deposited at the aperture lip varied significantly with time in the period from May until November 1985. Production by this population was estimated to be 0.055 g dry body weight/day for the period of 3 June until 8 November 1985. Estimates of the calorific value of the population in June and November 1985, obtained from the value of 5.45 kcal/g ash free body weight were 226.98 and 337.52 kcal/m-2, respectively. intertidal; invertebrates; molluscs; Fundy; recruitment; growth rate; life history; fauna; rockyGarrett, C. and R.

This report summarizes the discussions of about a dozen physical oceanographers, together with a few of our biological and geological colleagues. However, the emphasis reflects the opinions of the rapporteurs, and does not necessarily represent even a majority viewpoint.For the purpose of considering the environmental changes due to Fundy tidal power, we divide the Bay of Fundy and Gulf of Maine somewhat arbitrarily into inner and outer regions. The inner region consists of the area that would experience large changes in tidal elevation and currents. It comprises the headpond, together with a small region outside the barrage. The outer region consists of the rest of the Bay of Fundy and Gulf of Maine, in which changes in tidal regime would be only a few percent or less. oceanography; hydrography; Fundy; tidal power; Gulf of Maine; currents; circulation

The Bay of Fundy and Gulf of Maine form a complex oceanographic system, with considerable spatial and temporal variations in physical properties and behaviour. Freshwater input from rivers, wind, solar radiation, surface cooling and external water masses all play important roles in determining the patterns of water characteristics and currents, but the region is most remarkable for the exceptionally large tides of the Bay of Fundy.It is now generally accepted that these large tides are due to the near-resonant response of a system comprising the Bay of Fundy and the Gulf of Maine out to the edge of the continental shelf (Garrett 1972, 1974; Greenberg, 1975). The distinct tidal response of this system is partly due to its separation from the main body of the Atlantic by a change of depth by a factor of 30 or so.
It is only recently that we have realized the need for inclusion of the Gulf of Maine in any assessment of the impact of Fundy tidal power. Whether we need to look further away still is debatable. Garrett & Greenberg (1976) predicted changes in North Atlantic tides of at most a few mm, but the possibility of greater changes on the continental shelves adjacent to the Gulf of Maine has not been completely excluded. It is also possible that potential changes in water quality in the Gulf of Maine, to be discussed in this paper, might be felt "downstream" on the continental shelf of the East coast of the U. S. A.
A number of major papers (Bigelow 1927; Watson 1936; Hachey 1952, 1961; Bailey 1957; Bumpus 1974, 1975) have been written on the hydrographic structure and current patterns of the Bay of Fundy and Gulf of Maine. I shall refer to the findings of these and other authors only as required to illustrate my main theme: that the physical oceanography of the region is greatly influenced by tidal effects, and that changes in tidal current and elevation can be expected to lead to changes in other properties. Much of what I have to say is speculative, even as far as an understanding of the present regime is concerned, but where possible I hope to pinpoint some of the physical oceanographic phenomena that require further study if we are to predict, with sufficient accuracy, the results of developing tidal power.

A general summary of findings related to harbour porpoise from 1969 to 1975 is submitted, with preliminary data on numbers, distribution and movement (seasonal) in the vicinity of the Bay of Fundy. The data point to a low population size estimate. A life span of only 6-9 years is suggested, coupled with a low reproductive rate, which makes the species inflexible in response to exploitation. The magnitude of incidental catches gives cause for considerable alarm. porpoises; Fundy; distribution; population; cetacea; vertebrates; fauna; marine mammalsGaskin, D. E. (1983).

No abstract available. The following is part of the introduction to Chapter 16 which contains species description, keys to identification and distributions within the Quoddy region.The Bay of Fundy approaches are ecologically unique. The tidal range averages more than 7 m, and this causes extensive vertical mixing and hence cooler surface water temperatures during the summer months than in adjacent regions. Production is relatively high, and strong tidal currents and upwellings produce nutrient enrichment at certain locations which are, within broad limits, geographically constant in summer. Large local eddies also bring about concentrations of zooplankton between June and October (see Chapters 12 and 13), in amounts which attract numerous large baleen whales and keep them in the region for most of the summer and early fall. Considerable quantities of herring and mackerel enter the bay from late spring onwards, and these are prey for three or four species of small toothed cetaceans, the most abundant being the harbour porpoise, Phocoena phocoena. In former times, the harbour seal, Phoca vitulina was abundant in the region, but the population was reduced to a low level by bounty hunting. This bounty was imposed by the Federal Department of Fisheries because of the apparent involvement of the harbour seal in spreading the cod worm parasite. Despite reduction in harbour seal numbers to an insignificant level, the parasite continued to extend its range; the bounty was suspended for a time in the 1970's and harbour seals increased in numbers. By 1979, the bounty had been reimposed, largely in response to complaints by weir fishermen that seals were interfering with the netting of herring. The grey seal, Halichoerus grypus occurs in small numbers in the Grand Manan area, but is not a common species in the bay. While the grey seal is also a carrier of the adult form of cod worm, a bounty imposed in the Miramichi Estuary was designed to prevent numbers increasing to the point where the seal population might significantly interfere with the salmon fishery.

Information on the North Atlantic right whale, Eubalaena glacialis, accumulated since the previous COSEWIC report, prepared in late 1983, is summarized. The Bay of Fundy approaches still seem to be the most important summer ground for mothers with newborn calves. An analysis of historical data suggests that no comparable calving area existed on the west coast of Canada. The wintering areas for the majority of the eastern seaboard population remain unknown, although a significant concentration of mothers with calves has been found on the coastal shelf off Georgia. Photo-identification methods confirm a minimum population of about 207 animals on this coast. An increase in the size of this population remains unconfirmed. whales; Fundy; conservation; cetacea; marine mammals; vertebrates; fauna; distribution; populationGaskin, D. E., R. Frank, et al.

Arch. Environ. Contam. Toxicol. 12(2): 211.
Polychlorinated biphenyl (PCBs) levels were measured in tissues from harbor porpoises collected during 1971-77 from the Bay of Fundy (Canada) and adjacent waters. Levels of chlordanes and hexachlorobenzene (HCB) were measured in smaller numbers of the same series of specimens from 1975-77. PCB levels were relatively high in all tissues of sexually immature specimens of both sexes as well as adult males, and relatively low in adult females. Particularly high levels in four-year old males and three-year old females were related to a growth spurt at puberty with correspondingly elevated food (and hence PCB) intake per unit of time. Chlordanes were present in most tissues, with a maximum of 14 ppm in blubber. Only small quantities (0.12 to 0.43 ppm) of HCB were recorded. toxins; pollution; Fundy; contaminants; porpoises; marine mammals; vertebrates; fauna; cetaceaGaskin, D. E., R. E. Frank, et al. (1973).

Samples of blubber, longissimus muscle, liver, and cerebrum from 12 harbour seals (Phoca vitulina) were analyzed for DDT, dieldrin, PCBs, and total mercury content. The results were compared with those obtained previously for harbour porpoises (Phocoena phocoena). DDT and PCB levels appear to be of the same magnitude in the fat of seals from both southern New Brunswick and southern Maine, being lowest in a lactating female. Virtually no o,p'-DDT and relatively little dieldrin were found in seal fat, in contrast to porpoises, which contained significant amounts of both in the depot fat. Mercury levels were generally similar to those found for porpoises, but total liver Hg was considerably greater in adults from the New Brunswick islands than in those from the southern Maine ledges.contaminants; pesticides; pollution; metals; marine mammals; seals; pinnipeds; Fundy; porpoises; toxins; vertebrates; fauna; cetaceaGaskin, D. E., M. Holdrinet, et al. (1971). "Organochlorine pesticide residue in harbour porpoises from the Bay of Fundy region." Nature 233(5320): 499.
Organochlorine pesticide residues, together with polychlorinated biphenyl compounds of industrial origin, occur in many forms of life in the marine ecosystem. These compounds are concentrated through progressive trophic levels until relatively high levels accumulate in lipid-rich tissues of predatory seals, toothed whales and sea birds. The highest levels in marine mammal tissues published so far were in the blubber of ringed seals, Pusa hispida, from the Gulf of Bothnia (ÓDDT range 11-130 p.p.m., mean 120 p.p.m.), and in the blubber of grey seals from the Baltic Sea (ÓDDT range 97-310 p.p.m., mean 170 p.p.m.). One porpoise, Phocoena phocoena, from the east coast of Scotland contained a total residue concentration (dieldrin+DDT compounds) of 73.3 p.p.m.Sixty harbour porpoises, Phocoena phocoena, were collected by D. E. G. in western North Atlantic waters in 1969-70. Blubber samples from thirty and liver samples from twelve animals were chilled to sea water temperature (about 10° C) and frozen to ?20° C as soon as field conditions permitted (2-7 h). A two column fractionation separated organochlorine insecticides from the polychlorinated biphenyls (PCBs). The first step consisted of a 'Florisil' column for the separation of fatty coextractives from organochlorine insecticides. Up to 10 ug PCBs or 1 ug of DDT, DDE, or DDD were handled by the column to give a 90 to 100% separation. For best separation, two elutions with quantities most favourable to each group of compounds were made. Eluates were concentrated almost to dryness and redissolved in hexane for gas chromatography. Qualitative residue confirmation was achieved principally with thin-layer chromatography. Percentage recoveries were checked periodically by fortification directly into the oil obtained from hexane extraction. Average recoveries were: p,p'-DDE, 98 %; o,p'-DDT, 91%; p, p '-DDT, 90 %; p,p'-DDD, 95%; dieldrin, 89%. Data in Table I are not corrected for percentage recovery. Further study of the PCB residues is in progress. Their occurrence was, however, quite high, ranging from one to three times the levels recorded for p,p'-DDE.
Average dieldrin, ÓDDT levels in pregnant and lactating females were much less (1.37 p.p.m. of dieldrin, 69.03 p.p.m. ÓDDT) than in immature and resting females' blubber (7.75 p.p.m. dieldrin, 214.27 p.p.m. ÓDDT). Three sucklings had high levels (range 75.1-186.7; mean 138.8 p.p.m. ÓDDT). Residues may move into the depot fat in the foetus, or to the neonate through milk, or both.
The average ÓDDT level in the blubber of males (306.74 p.p.m., excluding sucklings) seems to be the highest published for a wild population of any mammal. The small sample size precludes speculation on residue variation at this time with respect to age, season and distribution. These results are ominous enough to merit further immediate attention to the status of contaminants in the higher trophic levels of the Bay of Fundy food web. pesticides; pollution; Fundy; porpoises; Gulf of Maine; contaminants; food web; marine mammals; toxins; vertebrates; fauna; cetacea

Samples of blubber from 60 male and 55 female harbour porpoises (P. phocoena) collected from 1969 to 1973, all but 11 from the east and west coast approaches to the Bay of Fundy were analyzed for DDT residues. The results were then compared according to sex, age class and year of collection. Factors complicating the study included variation of the levels of residue in individuals of the same age, perhaps due in part to differences in diet, and the relatively small size of samples. DDT residue levels showed a positive correlation with age in male harbour porpoises and a negative though less pronounced correlation in females, indicating that a significant portion of the accumulated DDT may be passed by females to the foetus or to the calf during lactation. It appears that DDT levels in porpoises of both sexes collected at the end of the study were very markedly lower than those of animals collected at the beginning. toxins; contaminants; pollution; pesticides; porpoises; marine mammals; Fundy; cetacea; vertebrates; faunaGaskin, D.

During 1969-71, 41 muscle and 20 liver samples were collected from harbour porpoises (Phocoena phocoena) in the Bay of Fundy region. These tissues were analyzed for total mercury content. Total Hg levels ranged from 0.21 to 1.92 ppm (average 0.75) in muscle tissue of males and from 0.26 to 2.58 ppm (average 1.02) in muscle tissue of females, from 0.89 to 18.30 ppm in liver tissue of males and from 0.55 to 91.30 ppm in liver tissue of females. Averages for the two latter series would be meaningless. A limited number (four muscle and six liver samples) of determinations of the methylated fraction were also made. In the muscle, Hg was virtually 100% methylated; in the liver the methylated fraction varied from 7.4 to 41%, being lowest in livers with highest total Hg. metals; contaminants; pollution; marine mammals; porpoises; Fundy; cetacea; toxins; vertebrates; faunaGaskin, D.

"Changes in mercury levels in harbor porpoises from the Bay of Fundy, Canada, and adjacent waters during 1969-1977." Arch. Environ. Contam. Toxicol. 8(6): 733.
Mercury levels were studied in a sample of 146 harbor porpoises taken in the Bay of Fundy, Canada, and adjacent waters during 1969-77. There was a clear correlation of increase in total Hg with age in the tissues examined. Except in the liver, mercury levels were less well correlated with weight and body length than with age. Levels in liver were thought to be those giving the best indication of changes in background levels of mercury in the food chain. Significant changes in Hg tissue levels appear to have occurred during the 9-year study period. Liver Hg levels in both sexes decreased from 1970 to 1971, remained low for 3 years, increased again in 1974, and continued to do so in the years following. Data are presented suggesting that this also occurred in other tissues. Since there is no evidence of a change in diet in this period, it is speculated that the decline in Hg levels could be correlated with a dominance of relatively mercury-poor Gulf Stream water in the Bay of Fundy approaches in 1971-73, as opposed to the usual dominance by waters of the Nova Scotia current. metals; pollution; contaminants; toxins; Fundy; porpoises; marine mammals; vertebrates; fauna; cetaceaGaskin, D.

No abstract available. From the introduction.The University of Guelph, Department of Zoology, has maintained a research presence on the southern New Brunswick coast since 1968-69. The cetacean research unit moved its summer base of operations to Lords Cove, Deer Island in 1970-71. Since that time the unit has collected cetacean sighting data, carried out species collections, and studied the environmental characteristics of the Quoddy region and adjacent areas.
In 1974 a pilot study was begun of the seabird and cetacean concentrations off Long Island and Brier Island, and on the Fundy coast of Nova Scotia in conjuction with the Canadian Wildlife Service. In 1976, with funding from the Department of Fisheries and Oceans, we started a comparative study of the interrelationships of upper tropic level animals and their prey species in three selected areas of the Bay of Fundy, one of which was the Inner Quoddy region.
In 1977, seabird species were inventoried in the Inner Quoddy region; coverage was limited to the area directly adjacent to Deer Island and Campobello Island because of manpower and time restrictions. Since then, more sporadic attention has been given to all species, but intensive studies of Bonaparte's gull and common and Arctic terns were made in 1978.

Gates, O. (1989). "The geology and geophysics of the Passamaquoddy Bay area, Maine and New Brunswick, and their bearing on local subsidence." Neotectonics in Maine. Augusta, Maine Geological Survey Bulletin 40. 11.
The basement rocks of the Passamaquoddy Bay area are Precambrian volcanics and Lower Ordovician shales, perhaps part of the Avalonian terrane. They are overlain by a thick section of Silurian-Lower Devonian marine volcanic rocks which are bimodal and accumulated in an extensional, subsiding tectonic regime. During the late Early Devonian Acadian orogeny, the volcanic pile was folded and faulted and intruded by gabbro, diorite, and granite. In the Late Devonian, coarse alluvial red-bed conglomerates and arkoses derived from erosion of the underlying volcanic pile and plutonic rocks accumulated in a fault-bounded basin apparently largely confined to the Passamaquoddy Bay area. Carboniferous faulting divided the rocks into separate fault blocks of differing stratigraphy and structural complexity. Intrusion of Lower Jurassic diabase dikes and development of the Fundian fault along the western margin of the Triassic-Jurassic basin beneath the Bay of Fundy marks the end of the bedrock record. The bedrock geologic record suggests that the Passamaquoddy Bay area has been one of crustal weakness prone to subsidence and faulting at least as far back as the Silurian. A concentration of historical seismicity and an abrupt change in magnetic patterns suggesting a crustal discontinuity further imply a weak underlying crust.In coastal Maine, postglacial rebound between about 13,000 and 9,000 yr BP was about 100 to 120 meters, ending with a stillstand at -65 meters. Since then the coast has submerged, rapidly at first but then slowing to a rate of 1.44 mm/yr by 5,000 yr BP. In Passamaquoddy Bay the differential downwarp of about 12 meters relative to the coast farther west, as shown by the reentrant of glaciomarine delta elevation contours, was largely completed by 5,000 yr BP. Limited archaeological and radiocarbon data suggest that from then to perhaps historical times subsidence was not much greater than that to the west along the Maine coast. Currently, subsidence appears to be faster than to the west, but the data from different sources give conflicting rates.
Most of the 12 meter differential subsidence of the Passamaquoddy Bay area was the response of a weak crust to the large stresses resulting from the large and rapid postglacial warping ending some time prior to 5,000 yr BP, augmented perhaps by isostatic disequilibriums due to the contrasting densities of neighboring rock bodies and to hydroisostatic loading of the crust beneath the Bay of Fundy as the sea rapidly deepened following the low stillstand.

A relict breeding assembly of grey seals (Halichoerus grypus) is present at Muskeget Island, Massachusetts. Additional grey seals are regularly observed along the coast of Maine, most likely originating from Canadian stocks. Archeological and historical records indicate the grey seal was previously more abundant in New England. Probable reasons for this decline include killing by man and disruption at haulout sites. The desirability of increasing the grey seal population number and breeding distribution is advanced as a management goal and justified on a biological and legal basis. A management and research program is proposed which includes monitoring, management recognition, habitat protection, and experimental translocation to establish new breeding assemblies of grey seals in New England waters. seals; marine mammals; pinnipeds; conservation; Gulf of Maine; population; vertebrates; faunaGilbert, J.

Aerial censuses of harbor seals in March 1981, revealed a late winter distribution throughout New England, from Long Island north to the Canadian border. An aerial census in June 1981, resulted in a total of 10,483 harbor seals counted hauled out on ledges and islands of the coast of Maine. This is nearly double the 5,786 seats counted by Richardson in 1973. Pupping occurs throughout the coast of Maine. Two harbor seals were captured at night using a spot light and hoop net. Both were tagged and one fitted with an ankle radio-bracelet and followed for 22 days. Repeated counts at ledges indicated consistent use by harbor seals throughout the summer. Disturbance resulted in local shifts in distribution, but not abandonment of the area. Fisheries with real or potential interactions with marine mammals, were identified. For each, a qualitative summary of documented interactions is presented. Certain fisheries have potentially significant interactions for fisheries. seals; marine mammals; population; distribution; Gulf of Maine; fisheries; pinnipeds; vertebrates; faunaGilbert, J.

Results from the second year of research on harbor seals (Phoca vitulina) and marine mammal-fisheries interactions in New England are presented. Objectives of the second year elaborate on our preliminary results in an effort to (1) investigate the status, distribution, and population discreteness of harbor seals in New England and (2) document interactions existing between commercial fisheries and marine mammal populations in New England.Seasonal distribution and movement patterns of harbor seals were monitored through aerial surveys and volunteer ground surveys. In addition one subadult was radio tagged and 19 seal pups were tagged to monitor movements of individuals and assess population discreteness. Varying degrees of seasonal haul-out site affinity were observed; certain haul-outs were used year round while others showed seasonal peaks of use. Ledges used by pups or for whelping were identified and their physiographic characteristics noted.
Marine mammal interactions with several commercial fisheries were investigated. A surface gillnet fishery for mackerel in Cape Cod Bay was sampled in mid-winter. Loss of netted fish to harbor seals was estimated at 0.3% of the season's landings and was not considered, by the gillnetters interviewed, to be as great a problem as gull depredation. Marine mammal damage to gear was difficult to assess but is apparently low. Twenty-four entanglements of Atlantic white-sided dolphins, harbor porpoise, and harbor seals, resulting in 7 deaths, were reported. Seventeen groundfish gillnetters, representing 3 regions of coastal Maine, were interviewed.
Loss of netted fish to marine mammals was reported as insignificant although occasional gear damage was reported due to whale collisions. In total, an averaged annual take of 118 small cetaceans (predominately Phocoena phocoena) and 22 harbor seals was reported by the 17 groundfish gillnetters. The rate of marine mammal entanglement was reported to be greatest during summer months on midcoastal fishing grounds and is likely related to the abundance of marine mammal species in the area.
Marine mammal interactions with other sport and commercial fisheries are discussed. The economic impact of codworm infestation on Maine groundfish packing plants was assessed through phone interviews. Nine of 16 firms contacted candle all cod received and report that the increased value of candled fillets outweighed the additional processing costs. seals; marine mammals; fisheries; conservation; distribution; cetacea; economics; Gulf of Maine; pinnipeds; vertebrates; fauna; population

Results from the third year of research on the harbor seal (Phoca vitulina concolor) population and the marine mammal-fisheries interactions in New England are presented. Our objectives were to elaborate on previous findings through (1) continued investigation of the status, distribution, movements, and population discreteness of harbor seals in New England and (2) developing means to document and monitor marine mammal conflicts with commercial fisheries in New England.Seasonal movement patterns and shifts in distribution of harbor seals in mid-coastal Maine were suggested from repeated aerial surveys of the study area. Sheltered ledges in upper reaches of the study area appear traditionally important during the rearing of pups. A mid-summer shift in seal numbers from relatively protected, inshore to more exposed, offshore ledges was noted.
Pups were captured to enable the marking and identification of individuals and aid in the determination of harbor seal population discreteness. Results suggest pups are capable of long-distance offshore movements in the first few weeks after weaning. The January 1983 and 1984 observations in the Cape Cod, MA area of pups tagged in Maine the previous summers, support the hypothesis that Maine seals contribute to the migrant group that overwinters in southern New England.
A small-take exemption permit was drafted on behalf of the New England groundfish gillnetters to allow their legal reporting of marine mammal conflicts. In conjunction with this permit application, we requested and acquired a scientific collection permit to allow the collection of biological data from legally taken specimens. These were the first steps necessary to document the actual extent of marine mammal entanglement and assess the impact that net-related mortality has on harbor seal and harbor porpoise populations in New England.

This report summarizes research activities conducted during 1984 under contracts NA-80-FA-C-00029 and NA-84-EA-C-00070 to the Northeast Fisheries Center, NMFS. The assessment of marine mammal-fisheries interactions was a primary goal under both contracts and represented the focus of 1984 research activities. Objectives were to:1) document the species and number of marine mammals incidentally taken in New England groundfish gillnets.
2) document the circumstances of entanglement and identify potential means of reducing or mitigating losses associated with entanglement.
3) identify population characteristcs of the marine mammals taken and assess the impact of this take on the populations involved.
4) assess the distribution and timing of the entanglements relative to the distributions of marine mammal populations and
5) investigate marine mammal conflicts with other fisheries to identify those qualifying for a small-take exemption. seals; marine mammals; fisheries; population; distribution; Gulf of Maine; pinnipeds; cetacea; vertebrates; fauna; conservation; economics
Gilbert, M. A. (1975). Distribution, reproduction, feeding and growth of Macoma balthica in New England, Doctoral Dissertation, University of Massachusetts.
This dissertation examines several aspects of the ecology of Macoma balthica (Linnaeus, 1758) on the New England Coast. The distribution of this bivalve and associated species across the intertidal were determined by sampling along transects at four sites; two in northern Maine and two on the south shore of Cape Cod. The zone of abundance moves from high in the intertidal in the north to progressively deeper in the subtidal toward the south, presumably due to the effects of temperature. The boundaries of this zone often appear to be further limited by competing species of amphipods. Two other sites on the south shore of Massachusetts one subtidal and one with varying sediment composition at one intertidal level, were also sampled. Analyses of the density and mean length relationships with sediment composition and tidal level at the six sites indicated that the most important influence on larval settlement within a site is probably the organic and silt-clay content of the sediment. Diversity indices (Shannon function, evenness, and richness) for the macrobenthos of the intertidal sites increased from north to south. Advisor: Dr. D. Craig Edwards.

Musculus niger and M. discors are small, rectangular to oval, dark brown, filter feeding mytilid bivalves that live attached to rock crevices or seaweed fronds by byssal nests. Their main area of distribution is high Arctic shores and their biology shows many adaptations to these conditions. In turn, these adaptations make them vulnerable to extinction in a locality by overcollecting. Malacologists contacted in a preliminary survey reported populations of these species at ten localities in northern Maine south to Starboard Island, Machias. I field-checked six of these localities and found populations at Crow Neck, Clarks Ledge, and possibly at Starboard Island.

The gaper clam, Mya truncata, is a fairly large, whiteshelled, filter-feeding bivalve that can be found intertidally in northern Maine, perhaps as far south as Mount Desert Island and generally subtidally elsewhere. A survey of malacologists resulted in reports of intertidal populations of this species in five localities, most of them in already protected areas (e.g. Mount Desert Island). During field checking, populations were found at Crow Neck, previously reported, and at Gleason Cove and possibly Starboard Island, both unreported previously.

During the late fall of 1987, domoic acid contamination of shellfish was responsible for severe illness in many Canadians. The contamination of the shellfish has subsequently been attributed to the occurrence of a toxic variety of the diatom, Nitzschia pungens. The toxin was first detected in mussels (Mytilus edulis) and soft-shell clams (Mya arenaria) collected from the shore in late July-early Aug. in the Bay of Fundy and vicinity. In this area, peak toxin accumulation occurred in these species in Sep.-Oct., then declined to not detectable. In the Cardigan River, P.E.I. and environs, the toxin accumulation did not become significant until late Nov. and peaked in Dec. toxins; Gulf of Maine; shellfish; Fundy; molluscs; diatoms; invertebrates; Fundy; fauna; phytoplankton; floraGilpin, J.

To estimate biomass and production, the cell volume of tintinnine ciliates has been assumed to be 50% of lorica volume. This assumption was tested using a high-precision digitizing system which measured individuals of 17 tintinnine species in samples taken in two annual studies of biomass and production in both tropical (Kingston, Jamaica in 1986) and temperate (Passamaquoddy Bay, Canada in 1983-1984) regions. Using this assumption, percent occupancies and hence, biovolume estimates, were overestimated by as much as 317% for tropical species and 178% for temperate species. Daily production estimates of the tropical tintinnine assemblage were overestimated by as much as 147%. Passamaquoddy; Quoddy; plankton; productivity; floraGodin, G. (1969). "Theory of the exploitation of tidal energy and its application to the Bay of Fundy." Journal of Fisheries Research Board of Canada 26(11): 2887.
Considerable progress has been made in the understanding of the concepts underlying the exploitation of tidal energy during the last 20 years; this progress has culminated in the actual construction of a tidal plant at the mouth of the Rance River near St. Malo, France. Since the Bay of Fundy is one of the largest reservoirs of tidal energy in the world, the theory of exploitation of tidal energy has been reviewed with a view to its application to the Bay of Fundy.The rate of change of the energy contained in an oscillating mass of water in a basin on a rotating earth can be written out using the equations of hydrodynamics. The concept of power transfer arises immediately, which enables one to follow the transit of power from one part of the basin to another. This makes it possible to establish a balance of the power present in the basin.
Only the potential energy present in the tide can be profitably exploited, and it is obtained by enclosing part of the basin by a dam in which some turbines and pumps are imbedded, as well as some complementary sluices. The emptying and filling of the enclosed part of the basin through the turbines during the fall and rise of the sea leads to the production of energy. The upper bounds of the energy available in this way can be easily established and it can also be readily shown that the use of pumps increases the amount of energy available. The actual amount of energy drawn from the reservoir is limited by the smaller range of the tide inside the reservoir and the efficiencv of the turbines. The timing and duration of the various operations involved in the operation of a tidal plant, pumping, generating power, opening or closing the sluices, waiting for a head to develop, can be studied quantitatively.
For this purpose the type and number of fundamental operations are carefully studied and accurate definitions are given of them, permitting calculations on a number of possible sequences of operations up to 25 tidal periods. The number of possible sequences is very large and it is not possible to study all of these sequences individually.
Under some circumstances a given sequence of operations for the actual times of starting and stopping the turbines, starting and stopping the pumps, opening and closing the sluices, waiting for a head, and the changes of level inside the reservoir can be calculated with the help of the calculus of variations. For instance, these quantities yield to systematic calculation if the plant is operated with the purpose of producing the maximum amount of energy. The calculus of variations, however, cannot help directly when other modes of operation are considered, such as operating the plant in such a way as to supply power only during peak demand.
The response of the basin to the oscillating ocean will be altered after the construction of the reservoir needed for the operation of the tidal plant. This modification may be important when the plant draws considerable amounts of energy from the tide.
With the help of the concepts developed it becomes an easy task to make a balance sheet for the tidal power present in the Bay of Fundy, restricting ourselves to M2, the main lunar semidiurnal constituent that is representative of average conditions. Many sites in the Bay of Fundy are found to be suitable for the generation of energy; some involve relatively simple engineering and yield modest amounts of energy such as the Digby site; others, such as the Minas Channel site, could yield very considerable amounts of energy but the engineering difficulties associated with their construction might prove prohibitive. tidal power; Fundy; hydrography; economics; oceanography

The following is the introduction to Chapter 15. A checklist of amphibians and reptiles of New Brunswick and Nova Scotia is included.Although this is basically a marine treatise the inclusion of the amphibians and reptiles of our marine coastal shoreline is justified if only to stress the gaps in our knowledge. There has never been, in the Bay of Fundy area, quantitative research on salinities in local coastal habitats nor examination of coastal amphibians and reptiles for marine prey species in their gut contents. Few persons are aware that barachois pools on both the open coast and in protected bays can have breeding choruses of anurans in early spring. The authors have observed Wood Frogs Rana sylvatica sylvatica, Leopard Frogs Rana pipiens pipiens, American Toads Bufo americanus, and the Northern Spring Peeper Hyla crucifer crucifer in such barachois habitats where cat-tails and cranberry were present, but where extreme spring tides flooded into that vegetational zone. These coastal habitats are essentially freshwater marshes in the spray zone or saline pools with a freshwater surface layer, although some supralittoral marine species occur there and may serve as food. Even on the exposed rocky shore we have seen toad tadpoles in the highest spray zone rock pools, where salinities (although not yet measured) were probably low due to rain or runoff.
Turtles have not been reported from barachois pools. The ubiquitous Eastern Garter Snake Thamnophis sirtalis certainly preys on coastal frogs and probably marine fish in tide pools. This snake is highly aquatic, so there is no reason not to suspect that it fishes in tide or marsh pools, as the closely related species T. elegans has been observed to do in British Columbia (F. Cook personal communication). Salamanders may be more sensitive to chemical changes in water bodies near the coast; nevertheless, the stream-loving habitat-specific Northern Dusky Salamander Desmognathus fuscus fuscus has been reported within 10 ft of the seashore. Recent research in the Appalachian Mountains has shown that salamanders are much more sensitive to acid-rain than frogs and may be completely eliminated from ponds and lakes where frogs are still maintaining populations. A monitoring of the effect of acid-rains and saline-rains along the coast of the Quoddy Region would be a worthy project. Another aspect worthy of study is related to hibernation and involves a significant difference at the ordinal level. Frog larvae hibernate and thus escape temperature extremes, oxygen depletion, and other winter stresses; salamander larvae are active in winter, even under ice, and are subject to winter kill in ponds due to oxygen depletion and perhaps, along the coast, from winter storms, tides, and spray.
In summary, we emphasize that coastal amphibians and reptiles in New Brunswick do occupy aquatic habitats at the shore, but ones that are basically freshwater, with non-marine flora. However, these habitats can be submerged during spring tides and storms and are undoubtedly subjected to saltspray. amphibians; reptiles; Fundy; vertebrates; fauna; inventory; salinity; rocky; habitats
Graham, M. (1936). "Investigations of the herring of Passamaquoddy and adjacent regions." Journal of Biological Board of Canada 2(2): 95.
The young herring ("sardine") fishery is seen as partly dependent on extremely local conditions. The fish first appear in the catches when about 12 months old in August. They are generally segregated into shoals of similar length (within an age-group). Certain areas tend to have herring of particular sizes. The "sardine" region is poorly supplied with herring fry rather than well supplied. Turbidity of the water is the only physical factor found possibly rendering the region specially attractive to herring. Euphausiids at the surface are one of the striking features of the heart of the "sardine" region. The principal species of plankton animals (Thysanocssa, Calanus, Sagitta) behave in a manner best explained by diurnal quiescence and nocturnal activity. Large landings of "sardines" in the "sardine" region as compared with other places is partly to be explained as due to especial ease of capture in that region, but it is uncertain whether there is a larger population of fish. It is clear that the proposed dams across the mouths of Passamaquoddy and Cobscook Bays would make considerable havoc of the exceptionally rich fishery in their neighbourhood. The fishery inside the dams would almost certainly be reduced to negligible proportions, since it seems dependent on immigration. It cannot be foretold whether the total effect on capture immediately outside the dams would be deleterious or not. There appears little possibility of a wide-spread effect, for example along the coast of Maine, or even seriously at Grand Manan. herring; fisheries; Passamaquoddy; Quoddy; oceanography; population; distribution; tidal power; life history; vertebrates; fauna; hydrographyGran, H. H. and T. Braarud (1935). "A quantitative study of the phytoplankton in the Bay of Fundy and the Gulf of Maine (including observations on hydrography, chemistry and turbidity)." Journal of Biological Board of Canada 1: 279.
In the Gulf of Maine life conditions of the phytoplankton were found to be in agreement with those described from the coastal waters of Northern Europe. The surface layers are during summer more or less stratified, indicating a fairly low degree of turbulence. Where the stratification is broken up, by vertical mixing, the waters are so transparent that the total effect of the turbulence on the productivity is favourable, the supply of nutrient salts resulting in an increase of the population, exceeding the loss by vertical transport.In the bay of Fundy, on account of the exceptionally high tidal range, the turbulence of the waters is so strong throughout the year that their nitrate and phosphate content nearly always was found to be high, even at the surface. The production of phytoplankton, therefore, can hardly be limited by the lack of nutrient salts. A relatively high turbidity of the waters and much cloudy weather make the productive zone shallow. Consequently the high degree of turbulence may even diminish the productivity of the waters by carrying the diatom cells down below the illuminated zone for a greater part of their life. A pronounced phytoplankton minimum in June probably is mainly a result of this effect of turbulence.

Thirty-seven sandpipers (29 semipalmated and 8 least) were collected in early September 1983 on an intertidal flat on the outer Bay of Fundy. Analysis of esophagus and gizzard contents revealed a variety of benthic invertebrates but the diets of both species were dominated by the amphipod Corophium volutator (Pallas). Females of both species ate larger Corophium than did males of the same species. Both least and semipalmated sandpipers were underutilizing a cohort of large (7-10 mm) Corophium. It is possible that the large amphipods have reached a size refuge from predation such that the energy required to handle and ingest these large prey offsets too great a portion of the energy obtained. shorebirds; Fundy; food web; feeding; vertebrates; invertebrates; fauna; predation; mudflats; birdsGroom, W.

The fishermen of the Grand Manan area expressed concern about the catching of large lobsters in the area from North Head, Grand Manan to White Head Island. It is believed by some of the fishermen from the southern part of the Island that the stock of large lobsters are the spawning stock for the Grand Manan lobster fishery. The Seal Cove fishery consists of lobsters in the one to one and one-half pound range with a considerable number of sub-legal sized lobsters present. The North Head fishery consists of large lobsters in the three to seven pound range (see Figure 1) with very few sub-legal sized lobsters caught. The fact that a large number of berried females are caught in this area raises the question-does this stock of large berried females actually supply the Seal Cove area with its small lobsters? lobsters; population; Quoddy; Grand Manan; fisheries; crustaceans; invertebrates; shellfish; fauna; inventoryHachey, H.

It would seem that the biggest factors concerned with the transportation of herring as "plankton" into Passamaquoddy Bay are the changing tidal amplitudes and the vertical movements of the fish. Once in the bay, the general circulation coupled with the vertical movement determine when and where the fish become available to the weirs.

Samples of Echinarchnius parma, collected during summer 1988 from three sites along the eastern coast of Canada (the northern Gulf of St. Lawrence, Chaleur Bay and the Bay of Fundy), showed sexual dimorphism in the shape of the oral surface in addition to marked changes in the camber of the abora surface related to the strength of wave and current activity. The oral surface is more concave in males than in females. The dimorphism develops as individuals become sexually mature and is pronounced for individuals measuring >4 cm in diameter. Associated with this shape difference, the volume of females is greater than for males, and this corresponds to the larger size attained by the ovaries compared to the testis. Shape differences between males and females are rare in echinoderms, and E. parma is the first species for which the sexes can be separated with a high degree of accuracy (>80%) on the basis of shape.

In his search for sources of power to meet growing domestic and industrial needs, man has always been intrigued by the thought of harnessing tidal forces. Nowhere in the world is there a more favourable place for such a project than the Bay of Fundy, for here are the world's greatest tides. Various circumstances determine that the bay itself is not an ideal site, but near its mouth, at the eastern end of the boundary between Canada and the United States, lie Passamaquoddy and Cobscook Bays. Separated from the Bay of Fundy and from each other by a series of islands and promontories, and with a mean tidal amplitude of about 20 feet, these bays are an ideal site for tidal power.Since the 1920s when Dexter Cooper first advocated a tidal power project, the possibility of harnessing the tides has been under general consideration or serious survey almost continually. In 1956, the governments of Canada and the United States of America referred the matter to the International Joint Commission, requesting examination "To determine the effects, beneficial or otherwise, which such a power project might have on the local and national economies in the United States and Canada, and, to this end, to study specifically the effects which the construction, maintenance, and operation of the tidal power structures might have upon the fisheries in the area".

The upper surfaces of sublittoral hard substrates in the Deer Island region of the Bay of Fundy, New Brunswick, support diverse, depth-zoned epibenthic communities of which ascidians form a minor part. Their population density was quantitatively studied from photo-transects taken between mean low water (MLW) and 30 m depth at four sites off the Deer Island coast and from 30-140 m depth along two photo-transects in Head Harbour Passage. All photo-analyses were aided by collections from transect survey sites, wharf pillings and salmon cage floats, to yield a total of 15 ascidian species encountered. The community in Head Harbour Passage is animal-dominated and in its deeper sections often shows three-dimensional bottom relief from horse mussel shells.

Mussels (Mytilus edulis) and clams (Mya arenaria) sampled from Brandy Cove and Chamcook Harbour in the Bay of Fundy, New Brunswick during August-October, 1988 had domoic acid concentrations from 1.2-38.0 mu g/g wet weight of whole tissue. 96.5% of the domoic acid in the mussels was in the digestive gland. Domoic acid was not detected in shellfish from Deadmans Harbour in the Bay of Fundy during the above period or from all 3 sites during the summer-fall of 1989. When domoic acid was detectable in shellfish, domoic acid was detectable in plankton tows (0.8_3.5 mug/g wet weight), and the dominant species was Nitzschia pseudodelicatissima. mussels; clams; molluscs; fauna; Fundy; toxins; invertebrates; shellfish; phytoplankton; flora; bivalvesHaya, K., J.

During July to September 1988, Atlantic mackerel, Scomber scombrus, were sampled from 10 locations in the Southwest Bay of Fundy, New Brunswick, Canada. Intestines and livers were extracted by the AOAC procedure for paralytic shellfish toxins. Intraperitoneal injections of the liver extracts were lethal to mice and the observed symptoms were typical of paralytic shellfish poisoning (PSP). Toxin concentrations ranged from 40 to 209 mug saxitoxin (STX) equivalents per 100 g of liver. Intestines sampled from mackerel with the most toxic liver extracts had toxin concentrations corresponding to 57 mug STX equivalents per 100 g of intestines. None of the other extracts from intestines were lethal to mice. Analysis of water samples collected during the same period indicated that a small bloom of Gonyaulax excavata occurred mid-to late July. mackerel; paralytic shellfish poisoning; Fundy; fish; vertebrates; fauna; toxins; phytoplankton; red tide; dinoflagellates; floraHaya, K., J.

During July 1988 a small bloom of Alexandrium fundyense occurred in southwest Bay of Fundy, New Brunswick, Canada. The highest concentration observed in a surface water sample was 7.5 x 10-3 cells/L on July 12. From July to the end of September, Atlantic mackerel (Scomber scombrus) were sampled from 9 locations. Concentrations of PSP toxins in liver extracts were measured by mouse bioassay and ranged from 40 to 209 mug saxitoxin (STX) equiv/100 g wet wt. PSP toxins (2-26 mug STX equiv/100 g wet wt.) were detected by HPLC analysis in 5 of 6 gastrointestinal tract extracts. In all but one sample, saxitoxin was greater than 97% of the total PSP toxins content in liver.

The toxin profiles of dinoflagellates and zooplankton collected during a Gonyaulax excavata bloom in the Bay of Fundy 1980 were analyzed. Results indicate that the zooplankton did not appreciably alter the toxin composition after ingestion of G. excavata. It is believed that fish kills involving toxin transfer through herbivorous zooplankton are caused by the same complex of toxins as present in the dinoflagellates. zooplankton; paralytic shellfish poisoning; toxins; Fundy; dinoflagellates; fauna; phytoplankton; red tide; invertebrates; floraHehre, E.

Executive Summary:
Public law 381 was enacted by the Maine Legislature in 1991 and sets forth the process for application for net pen aquaculture leases in Maine as well as the requirements of the Finfish Aquaculture Monitoring Program (FAMP), the responsibility for which rests with the Maine Department of Marine Resources (DMR). The FAMP is a comprehensive monitoring program covering benthic impacts as well as water quality impacts, specifically affects to dissolved oxygen. This report presents and summarizes results of sampling conducted from September 19 through October 27, 1994 at all 25 currently active finfish culture sites in Maine.In accordance with the FAMP, dissolved oxygen profiles were taken at three specific distances from the finflsh cage structures: 1) at 100 meters, or » 300 feet, upcurrent of the structure, 2) within 5 meters, or » 15 feet, downcurrent of the structure, and 3) 100 meters, or » 300 feet downcurrent of the structure. A Sea-Bird Electronics, Inc. SBE 19 SEACAT water column profiler equipped with a pump, a Senso-Metrics Sp 91FFS pressure sensor (S/N 8M187), a temperature-conductivity sensor (S/N 254), a Beckman dissolved oxygen sensor (S/N 0-10-13), and an Innovative pH sensor was used for this survey.
As a general rule, dissolved oxygen concentrations in the vicinity of finfish culture operations in Maine are either at or slightly above saturation, even during early morning hours. Dissolved oxygen saturation depression can be observed immediately downcurrent of the cage systems (within 5 meters) and is usually in the order of 5% to 10% lower than the upcurrent saturation values. Two saturation levels below 80%, the Maine Department of Environmental Protection's standard for Class B marine waters, were recorded at the most intensively operated of the currently active sites, but both were only one percentage point below the standard at 79% of saturation.
Dissolved oxygen concentration recovery occurs rapidly only a short distance from the cage structures. In most cases, D.O. saturation 100 meters downcurrent of the cage structures is the same or only slightly below upcurrent values. Even in cases where significant D.O. saturation depression occurs adjacent to the cages, D.O. saturations 100 meters beyond the cages are only 3%-4% lower than upcurrent values.
Based on the results of this monitoring survey, finfish culture sites can be expected to meet or exceed the dissolved oxygen standards for Class B waters. This conclusion, however, should not be taken as a suggestion that finfish culture operations have little or no overall environmental affect, for as other parts of the Finfish Aquaculture Monitoring Program have shown, substantial impacts to the benthos can occur while having only limited affect on water column dissolved oxygen concentrations. aquaculture; fish; vertebrates; fauna; nutrients
Hicklin, P. W. (1987). "The migration of shorebirds in the Bay of Fundy." Wilson Bull. 99(4): 540.
Large populations of 34 species of shorebirds migrate in late summer and fall to the wide muddy intertidal areas of the upper Bay of Fundy in preparation for the transoceanic flight to South American wintering grounds. Southward migration through Fundy extends from 1 July to 11 November, although the main passage usually occurs between 20 July and 20 September. Shorebirds are most numerous during August. The average length of stay for the Semipalmated Sandpiper (Calidris pusilla) is 15 days. Estimates of total numbers for the migratory period of the nine most common species range between 800,000 and 1,400,000 birds. migration; shorebirds; birds; Fundy; intertidal; population; inventory; vertebrates; fauna; mudflatsHicklin, P.

This paper presents a brief summary of the major groups of birds which occur in the Bay of Fundy and discusses ecological studies of birds undertaken since 1970. Intertidal mudflats, salt marshes and areas of upswelling tidal currents near small islands are the major habitats used by birds in Fundy. Waterfowl, shorebirds (plovers, sandpipers and phalaropes) and seabirds (shearwaters, gulls and terns) are most numerous during autumn migration. Many of the studies discussed are recent and in large part remain unpublished.

No abstract available. The following is the introduction to Chapter 17.The coastal forest in the Quoddy Bay area is a highly variable product of both maritime and terrestrial processes. It is here defined as the forest or dominant vegetation above the high-tide mark of all tides and extending inland to the point where marine influences and the biotic communities associated with these become negligible components in the ecosystem (Dickinson 1977). It is a transition zone between tidal and terrestrial characterized in its entirety by a great diversity of species, a reflection of less extreme ecological conditions and a variety of niches. The vegetation of the Quoddy Bay Region of southwestern New Brunswick is the result of many factors including glacial, climatic, geological, and human historical, and has been affected by fire, disease, drought, wind, salt spray, plant migration rates, and the availability of a seed source. Chance is also involved in the distribution of plants. terrestrial; Passamaquoddy; Quoddy; ecology; distribution; flora

Seventeen parasitic copepods of the family Pennellidae were found on a Minke Whale, Balaenoptera acutorostrata, captured at Blacks Harbour, New Brunswick. The characters of five specimens examined in detail agree with published descriptions of Pennella filosa.

The occurrence of Caligus elongatus on Atlantic salmon (Salmo salar) cultured in marine waters in the Passamaquoddy Bay region of the lower Bay of Fundy is reported. Two size classes of cultured salmon (smolts and market size) were examined. Prevalence of C. elongatus was 54.5% on market fish and 54.7% on smolts. Intensities of infection for market fish and smolts were recorded as 2.41 and 2.58, respectively. Overall sex ratio of adult C. elongatus on infected salmon was 1:1.4 females to males; mean number of eggs per gravid female C. elongatus was 169. copepods; salmon; aquaculture; Passamaquoddy; parasites; fish; vertebrates; fauna; invertebrates; Quoddy; zooplanktonHogans, W.

The biology of three species of sea lice, Caligus curtus, Caligus elongatus and Lepeophtheirus salmonis from Atlantic salmon (Salmo salar) cultured in marine waters of the lower Bay of Fundy was examined in 1988-89. Three cage-culture sites in and adjacent to Passamaquoddy Bay were the sites of host examinations for sea lice during a 9-mo period (July through March). Both field and laboratory experiments were completed during the study period. Abundance and distribution of all three species were found to be related to water temperatures in the study area. Increased water temperatures resulted in greater numbers of parasites. parasites; salmon; aquaculture; Quoddy; Passamaquoddy; invertebrates; zooplankton; fish; vertebrates; fauna; copepods; temperatureHollingshead, K.

Meganyctiphanes norvegica (M. Sars) is a very common euphausiid in the North Atlantic. In the North East Atlantic, the life history and biology has been worked out in great detail. However, very little work of this nature has been done in the North West Atlantic. In view of this fact, a life history study of M. norvegica in Passamaquoddy was carried out. Monthly field collections for a 19-month period, helped to determine the growth rate for this crustacean as well as the time of breeding and spawning. This euphausiid spawns from July to August and the resulting adolescent attains sexual maturity in one year. Growth begins in April and continues to August; from September to the following April, there is very little growth of the euphausiid. In April, it resumes the same pattern as the previous year. However, after breeding, these year I animals (now year II), will soon die and thus the life span is only two years. Advisor; Dr. S. Corey.

The Bay of Fundy is a peculiar body of water in a number of respects. From its broad opening into the Gulf of Maine, its rather straight sides converge towards its head, and at the same time the depths decrease considerably. It has, indeed, the shape of a half cone, considerably flattened out and with the plane surface horizontal. This shape lends itself to a very full development of the tidal oscillations, which has made it famous for its high tides.

No abstract available. Introduction:...The Bay of Fundy is a rather discrete body of water hydrographically and contains extremely well-mixed water, which possibly explains the apparent uniformity of the herring population... The Passamaquoddy region of southern New Brunswick (Fig. 1) offers exceptional opportunities for studying movements of these herring during the period in their life history from the stage of metamorphosis, when the adult form is assumed, up to the stage of approaching sexual maturity... They are captured almost wholly in weirs...As these weirs are stationary, herring are taken only when moving towards and into them. Capture, therefore, is evidence of movement of the fish, which may be either active or passive. Activity varies with the temperature of the water... The season for rapid growth and, therefore, presumably of most frequent and prolonged feeding is from May to September... the principal growing and feeding months, June, July and August show lower catches...

Development, beginning in 1876, of heavy fishing for "sardines", the yearling herring available in and near Passamaquoddy Bay between New Brunswick and Maine, was followed by decrease in numbers of older fish. The very local and very fat "Quoddy River" herring disappeared promptly. The immense accumulated stock of large-spawning herring lasted ten years or more after recruitment was thus greatly reduced. This stock was being coincidently shifted from the Quoddy region, apparently owing to reduced rainfall.The normal seasonal shifting of these fish is between the outer side of Grand Manan Island in summer and near the mainland in winter. In midsummer of 1871, their numbers at Grand Manan began to diminish and for four years remained very low. They were as abundant as ever in winter near the mainland, but farther from shore and more numerous eastward. They appeared inside the Reversing Falls of the Saint John River, whose outflow goes to Grand Manan, in all four years of their scarcity at Grand Manan. Large herring appeared in unexplained numbers at Quaco, east of Saint John, from 1878 to 1881 and then declined. A movement across the Bay to Nova Scotia became evident by a marked rise in Annapolis County in 1881, and, farther in, in Kings County in 1882, in each case lasting for four years and not going beyond the mouth of Minas Channel. These fish seemed to make the circuit of the Bay, affecting catches at its head and on to the New Brunswick side, with return to the Saint John outflow by 1884. Farther out, other lots reached the Nova Scotian coast from Digby to Cape Sable in 1881, remained high for four years and then declined. By 1891, catches everywhere were down to a very low level, indicating exhaustion of the stock. herring; fisheries; Quoddy; Passamaquoddy; ecology; distribution; conservation; population; vertebrates; fauna

The explanation for the concentration of weirs and of the sardine fishery in the archipelago across the entrance to Passamaquoddy Bay is seen as being the way in which the sardines are carried from their wintering grounds outside into the archipelago, which provides many and varied locations for their capture in weirs. The object of the oceanographic party in H.M.C.S. LABRADOR was to make a preliminary survey of water conditions in the Canadian Arctic, to note marine mammal populations, to make a collection of plankton for studies in marine biology, and to gather data on ice and weather conditions. herring; Passamaquoddy; oceanography; fisheries; Quoddy; hydrography; faunaHurley, P. C. F., S. Corey, et al. (1983). "Distributional patterns of chaetognaths in the Bay of Fundy." Canadian Journal of Zoology 61(10): 2257.
Nine species of chaetognaths were found in the Bay of Fundy: Sagitta elegans, S. tasmanica, Eukrohnia hamata, S. maxima, S. lyra, S. enflata, S. hexaptera, S. serratodentata, and Pterosagitta draco. Sagitta elegans was the dominant and only native species and maintained a centre of very high abundance in the study area. It is suggested that surface circulation carries young out of the Bay of Fundy and that the center of abundance is maintained principally by immigration from outside the Bay and by interaction of adult specimens with the hydrographic conditions. Sagitta tasmanica was the second most abundant species and an immigrant carried into the Bay of Fundy by surface circulation. The distribution and abundance of E. hamata indicated a regular but variable inflow of slope water. The occurrence of S. maxima and S. lyra, and S. enflata, S. hexaptera, S. serratodentata, and P. draco indicated periodic inflow of oceanic boreal and (or) Gulf Stream waters.

Technical Report No. 428 (which was dated December 1973 and published in March 1974) referred to a Bay of Fundy herring situation that has since been transformed. The report did not, in fact, take into account changes that had already occurred by the end of 1973 and, since 1973, further developments have taken place along lines that could not have been predicted in detail at that time. As a result, virtually all of the data and analysis presented here are new. This section discusses the nature of the changes. Their direct relevance to the proposed construction of the refinery will be dealt with separately.The changes fall into three categories. Changes in the management regime, in the industrial regime, and in our understanding of the biology of the herring stocks of the area.

Summary. The number of genetically distinct herring stocks is determined by the number of distinct, geographically stable larval retention areas. Spawning sites in these areas may be highly localized or dispersed. Absolute population size mostly depends on the retention area available to the density-dependent larval-postlarval stage. Although the extreme seasonal range of spawning time shown by Atlantic herring is not fully accounted for by a new hypothesis, current theory is not supported by the hypothesis or by empirical data. The management implications are discussed. herring; fisheries; distribution; genetics; reproduction; Northwest Atlantic; population; vertebrates; faunaInternational Passamaquoddy Fisheries Board (1950). Report to International Joint Commission on scope and cost of an investigation of Passamaquoddy Tidal Power Project, Washington, D.C.
In April 1949 the International Joint Commission appointed the International Passamaquoddy Engineering Board to assist and advise the Commission in carrying out the assignment in accordance with the terms of reference by the Governments of the United States and Canada of November 9, 1948. The reference related to plans for the development of hydroelectric power at Passamaquoddy Bay in the State of Maine and the Province of New Brunswick. The Commission was requested to review existing plans, report on the scope and cost of the investigation which would be necessary to determine whether any existing plan, or any other plan to use the waters of Passamaquoddy and Cobscook Bays is practicable and desirable from the point of view of public convenience and necessity, and recommend as to the basis for apportioning the cost of such an investigation between the two countries.

"An inventory of distribution and variation in salt marshes from different settings along the Maine coast." Neotectonics in Maine, Maine Geological Survey Bulletin 40. 69.
Planimetry studies of maps of coastal geology prepared by the Maine Geological Survey show that over 3000 separate tidal marshes, encompassing approximately 79 km2, lie along the coast of Maine. The distribution of tidal marshes as well as their size and vegetation are shown to be related to geologic setting, sediment supply, and developmental history, all of which vary greatly along the 5970 km long coast. Systematic surveys of vegetation in 18 marshes reveal much variability in species composition, species richness, and zonation patterns. Species composition is influenced by freshwater input. Species richness is higher in older marshes situated in stable geologic settings. Zonation patterns represent a transition between those of southern New England and those of the Bay of Fundy region. inventory; distribution; wetlands; geology; Gulf of Maine; salt marsh; diversity; estuarine; floraJacobson, H.

Systematic studies of vegetation on 18 salt marshes along the coast of Maine show that the vegetation is highly variable in species composition, species richness, and zonation pattern. Marshes with high species richness are found in relatively stable geologic settings, while unstable marshes at the base of erodible bluffs have low species richness. Species composition is influenced by freshwater input. Salt-marsh zonation varies greatly in both the number of zones present per marsh and the species assemblages within zones. With a few notable exceptions, the vegetation of salt marshes in southern Maine is similar to that of marshes in southern New England. Salt-marsh vegetation in northeastern Maine is more similar to that of marshes in the Bay of Fundy region. wetlands; zonation; Gulf of Maine; salt marsh; flora; estuarineJacobson, H. A., G. L.

Planimetry studies of coastal geology maps prepared by the Maine Geological Survey show that there is more than an order of magnitude more tidal marsh area in the state of Maine than documented in previously published estimates. The highly convoluted coast of Maine, which is approximately 5,970 km long, contains approximately 79 km2 of salt marsh, far more than any other New England state, New York, or the Bay of Fundy region. Reasonable estimates for the per unit primary productivity of salt marshes lead to projections of total marsh productivity on the order of 1010 g dry weight/yr for the Maine coast and 1011 g dry weight/yr for the Gulf of Maine as a whole. Distribution of tidal marsh area is strongly controlled by coastal geomorphology, which varies considerably along the coast of Maine. wetlands; tides; geology; maps; Gulf of Maine; geomorphology; salt marsh; flora; estuarine; distributionJamieson, G.

Levels of Gonyaulax ecavata toxin in sea scallop (Placopecten magellanicus) tissues were monitored in eastern Canada on a monthly basis between 1977 and 1981. All tissues but the adductor muscle were found to be highly toxic in Bay of Fundy scallops, with negligible toxicity observed in scallops from Georges Bank, the outer Scotian Shelf, and Northumberland Strait scallops. Level of Bay of Fundy toxicity was much higher than previously observed (maximum digestive gland toxicity: 150,000 mug/100 g in March 1978), and recent average monthly toxicity for Bay of Fundy scallop the roe ranged from 184 to 286 mu g/100 g. Considerable fluctuation in toxicity can occur between adjacent months, and peak toxicities in sea scallops occur during fall and winter months. Scallop roe fisheries should be permitted to be established for scallops from the northern part of Georges Bank and Northumberland Strait. However, a closed zone for scallop roe should be established in the Bay of Fundy and adjacent Scotian Shelf. paralytic shellfish poisoning; Fundy; scallops; molluscs; toxins; Northwest Atlantic; invertebrates; fauna; bivalvesJohnson, W.

Canadian Journal of Fisheries and Aquatic Sciences40 (2): 139.
A simulation model of Atlantic herring (C. harengus harengus) locomotion was used to predict the movements and distribution of 2-year-old juveniles during the summer within the Quoddy region of the southwestern Bay of Fundy. The model assumed herring (i) swim at speeds of 1-2 body lengths per second, (ii) exhibit positive rheotaxis, and (iii) display cross-current movements whose frequency varies inversely with the speed of the current. Independent sets of simulated fish schools were introduced into a computer model of the study area at two sites (Letete approaches, Head Harbor approaches) and tide phases (slack low water, slack high water). Only those simulated schools entering through the Letete approaches at slack low water yielded the spatial pattern showing significant concordance with catch-by weir records, acoustic survey data, and the distribution of foraging flocks of common terns (Sterna hirundo). The simulation indicated high mortality due to the weir fishery and the possibility of size-segregation in Quoddy herring. model; herring; distribution; Quoddy; fish; vertebrates; faunaJury, S.

A literature review and new data are used to clarify geographical patterns of community response to release from heavy grazing by green sea urchins, Strongylocentrotus droebachiensis (O.F. Mueller), within the north-west Atlantic region. Large geographical areas identified where urchin-removal experiments have not been conducted are the Passamaquoddy Bay area of the northern Bay of Fundy, the south and west coasts of Newfoundland, and southern Labrador. Within the north-west Atlantic region, there has been variation in the degree of domination by Laminaria species of post-urchin-removal communities. This is probably due, at least in part, to variation in the availability of Laminaria populations in refugia from urchin grazing. The following hypothesis is developed and given a preliminary test: in eastern Newfoundland, the absence of refugial Laminaria longicruris populations is due to periodic ice-scour. urchins; distribution; algae; seaweed; Northwest Atlantic; invertebrates; flora; fauna; ecology; food webKehoe, F.

Apparent increases in cormorant Phalacrocorax auritus populations have coincided with decreases in return rates of Atlantic salmon Salmo salar smolts from the Salmon Genetics Research Program in Passamaquoddy Bay, New Brunswick. In 1986, cormorants were collected to investigate the possibility of cormorant depredation contributing to this decline. The proportion of smolts in the stomachs of a sample of 117 cormorants was approximately 0.10%. One Carlin and 16 micro tags were recovered in guano samples taken from four cormorant colonies. Fourteen of these tags were identified with eight different year classes of smolt released between 1976 and 1986. The estimated depredation rate from the 1986 release was 0.20%. It was concluded that cormorants are a relatively minor factor affecting return rates of salmon in the SGRP. seabirds; salmon; Passamaquoddy; Quoddy; vertebrates; fish; fauna; feeding; anadromous; birdsKelley, J.

Seven embayments along the Maine coast (Saco Bay, Casco Bay, Sheepscot Bay, Eggemoggin Reach, Machias Bay, Cobscook Bay, and Oak Bay) were surveyed for evidence of late Quaternary faulting by seismic reflection methods. The bays are representative of all coastal compartments in Maine, and all are located near regions of Paleozoic or older faults. In more than 1,000 km of seismic reflection profiles one possible recent fault was resolved along with numerous slump and gas deposits. While one might argue that faulting triggered the slumps that were observed, no consistent association of slumps and faults was recognized. Slumps appear confined to the margins of deep channels where tidal current action, possibly in conjunction with natural gas evolution, triggers their occurrence. Instead of finding continuous slumping along a basin, as might be the case if faulting initiated the slumping, the slump deposits were widely scattered and even occurred in basins with no inferred bedrock faults.The possible recent fault was observed in Oak Bay, along the Canadian border. In this area of frequent seismic energy release tidal range is also extreme. The feature indicated as a possible fault may, thus, be a manifestation of current reworking of Quaternary sediment. It is significant that this area was the least well known from previous work and interpretation of subbottom reflectors was often ambiguous. seismicity; geology; Gulf of Maine; Cobscook; Quoddy; tides
Kerswill, C. J. (1960). "Effects of proposed Passamaquoddy power project on anadromous fishes in Canadian waters." Journal of Fisheries Research Board of Canada 17(5): 713.
Atlantic salmon, smelt, alewives, shad, eastern brook trout, and introduced brown trout occur in waters that will be affected by the Passamaquoddy power project. The first four species are taken occasionally in herring weirs but total annual landed values did not exceed $6,000 in the period 1937 to 1956. Salmon and trout have high potential value for angling, subject to improvements in local river management.Construction of tidal power dams should overcome the present lack of typical estuarine conditions in the Passamaquoddy area and favour production of anadromous species. An improved sport fishery for sea-run trout could develop. Realization of the potential production of Atlantic salmon, alewives and shad, but possibly not sea-run trout, would depend on satisfactory access from the Bay of Fundy to the impounded areas. tidal power; Passamaquoddy; Fundy; Quoddy; fisheries; ecology; anadromous; recreation; economics; vertebrates; fauna; tourism

A bacteriological study of the Chamcook portion of Passamaquoddy Bay, Shellfish Area New Brunswick 41, was conducted by the Mobile Laboratory Service of the Public Health Engineering Division during the October 5-November 4, 1966, period. A total of 100 water samples and 4 clam (Mya arenaria) specimens collected from 22 sampling stations were subjected to standard coliform and fecal coliform density tests.

On the occurence of silica in the waters of the Passamaquoddy Bay region. Contributions to Canadian Biology and Fisheries New Series. Hydrographic Series D 4.
A study of the occurrence of silica in the waters of Passamaquoddv Bay region has shown very little difference in amount from top to bottom in localities where the turning over of water was very marked, but where the water movement was not so pronounced the values varied considerably with depth. The silica content of the water decreased during the summer months. Fresh water tributaries to the bay had a higher silica content than that of the waters of the bay itself.

The work which forms the basis of this report was done at the Marine Biological Station, St. Andrews, New Brunswick, in April, May and June, 1912, and May, June, August and September, 1913. The region covered is from St. Stephen, at the head of navigation on the St. Croix river, to Grand Manan.The Algal flora of this region is distinctly boreal in character, as is shown by the luxuriant growth of Fuci and Laminariae, and by the occurrence in comparatively shallow water of Dictyosiphon hippuroides, Halosaccion ramentaceum, Saccorhiza dermatodea, Agarum turneri and Monostroma fuscum blyttii.
There is a considerable difference in the Algal flora of what we may term "inside" and "outside" points. By "inside" we mean on the mainland side of Passamaquoddy bay, by "outside" the shores of the islands (Deer, Pendleton's and Macmaster's) which form the outer boundary of the bay, and all points beyond these islands. These differences in the Algal flora may be pretty definitely traced to differences in the salinity of the water "outside" and "inside." Inside the water has a specific gravity at the surface of from 1.0226 to 1.0235, and a percentage of total salts of from 2.99 to 3.202, while outside waters have a specific gravity of from 1.0235 to 1.0242, and a total salt content of from 3.201 to 3.280 per cent. For these figures I am indebted to the work of Mr. G. G. Copeland in 1909, published in the report of the Biological Stations of Canada "Contributions to Canadian Biology, 1906-1910."
The only paper dealing with the algae of this region of which I have any knowledge is Professor D. C. Eaton's "List of Marine Algae collected near Eastport, Maine, in August and September, 1873, in connection with the work of the United States Fish Commission," and, where his records are for Canadian stations and for species which I have not collected, I quote them here.
In many countries the marine algae are of great economic importance, as food, as the source of food products such as isinglass, in the production of a "size" for textile fabrics, in the clarifying of beer and wines, as the source of iodine and potassium, in the manufacture of a very strong adhesive known as seaweed glue, in the production of a demulcent for use in relieving coughs, and as a fertilizer. Except that some are put to the last-mentioned use along the coast, and small quantities of dulse (Rhodymenia palmata) are gathered and dried for eating, the marine algae are made no use of in Canada, and therefore represent one of our undeveloped resources. algae; Passamaquoddy; Quoddy; Fundy; flora; distribution; economics; seaweed; inventory

Despite over 50 years of international protection, the North Atlantic right whale population remains precariously low. Current estimates indicate that no more than 350 individuals are alive today in the western North Atlantic (Crone and Kraus 1990). The relationship of the western North Atlantic whales to the few right whales observed in other areas of the North Atlantic during this century (Brown 1986) has been a mystery. However, recently acquired photographs and the subsequent identifications have expanded our view of right whale population ranges and stock differentiation, and the data are presented here. whales; distribution; population; conservation; Northwest Atlantic; marine mammals; vertebrates; cetacea; faunaKohler, A.

It was thought possible that differences in feeding and resultant growth were related to some other seasonal factor besides water temperature. Therefore it was decided to carry out some further tests under conditions of controlled water temperature to measure its effect alone. These controlled water temperatures were also useful for running experiments on changes in the cod's maintenance requirements at various temperature levels. One series of experiments was carried out in 1952 and another series in 1963. fish; cod; growth rate; Gulf of Maine; feeding; temperature; vertebrates; faunaKohler, A. C. (1979).

No abstract available. From the summary: Presented below is a summary of our conclusions regarding the proposed listing of Atlantic salmon as threatened in the seven Downeast rivers, and comments on State/Federal management plans for salmon.We conclude that formal listing of salmon in these rivers is not justified on the basis of the scientific information presented in the Proposed Rule. For our evaluation, we used a metapopulation perspective whereby definition of Maine Atlantic salmon is dependent upon the magnitude of temporal presistence of individual populations and exchanges of fish among them. Consideration of all available data and population genetic and demographic theory suggest that the proposed listing is not based on objective evidence, but rather on a general "conservative scientific philosophy." By extension, this conslusion implies that additional rivers in the State, and, specifically, the four rivers of concern, should also not be listed. The principal observations supporting this position are: (1) the magnitude of past stocking of Maine rivers with Atlantic salmon of sythetic origin facilitated introgression and eliminated local variability, and (2) current "natural" or "wild" reproduction is likely that of offspring from hatchery alterations, the Proposed Rule seeks to list organisms that no longer represent an evolutionary significant component of this species.

North Atlantic right whale mortality rates range from 2% to 17% over the first four years of life. Sources of mortality in this population include ship collisions, entanglements, and natural causes. A combined analysis of stranding data, entanglement records, and photographic information indicates that approximately one third of all right whale mortality is caused by human activities.

Advances in technology during this century, coupled with world population increases and changes in socio-economic patterns, have had a profound impact on our traditional way of life. Heavy industry has developed to an unprecedented level and has spread from the original centres of development to new areas; including coastal sites which have historically drawn their sustenance from resource-based industries such as fishing. As a result, resource-based industries are increasingly in conflict with heavy industry since they can be, and have been, eliminated by heavy pollution. In addition, technological advances in fishing methods and resultant overharvesting have resulted in greatly reduced stocks of many fish species. At the same time, and largely as a result of these developments, man is currently looking at new ways to grow and harvest marine food species by controlled methods in the ancient, but new, science of aquaculture. Also, applied science is looking to previously unutilized food, drugs, additives and so on. Advisor: Dr. A.J. Hanson. conservation; Fundy; Gulf of Maine; fisheries; aquaculture; economicsKu, L.

Observations, numerical modeling, and theoretical calculations show how the 18.6-year modulation of the main lunar semidiurnal tide in the Bay of Fundy and Gulf of Maine is reduced from its astronomical value of 3.7 percent to 2.4 percent by the effects of friction and resonance.

A 4-year study of the life history of T. inermis was conducted in Passamaquoddy Bay. A comparison of the growth pattern and eye morphology showed that T. inermis in Passamaquoddy Bay is part of a Bay of Fundy population centered in the Grand Manan Basin. Spawning occurs in the spring and the young stages are found near the surface during the summer. Thysanoessa inermis lives for 2 years in the Bay of Fundy and spawns at the end of the 1st and 2nd years. Gonadal development is described in detail. Growth in both years is rapid during the summer months with little or no increase in size during the winter. The growth rate of the female surpasses that of the males in the 2nd year. The neglecta form of T.inermis (year class 0 animals) lives in the middle to upper layers and is morphologically different from the inermis form (year class 1 animals) which lives in the deepest layers.

Length to weight and other morphometric relationships were examined and the effects of preservatives on M. norvegica and Thysanoessa inermis (Euphausiacea) from the Bay of Fundy were described. Weight increased exponentially with length, showing no significant difference between sexes. The relationships between two different total length measurements and carapace length are given. The change in slope of the line for the carapace to total length relationship for 0 and 1 year class animals revealed a change in body allometry. A series of 14 weight change relationships from fresh to formalin through alcohol to dry weight demonstrated significant weight loss and change in total length depending on preservative or combination of preservatives used. euphausiid; crustaceans; Fundy; invertebrates; fauna; growth rate; zooplanktonKulka, D.

Seven species of euphausiids were found in the Bay of Fundy: Meganyctiphanes norvegica, Thysanoessa inermis, T. longicaudata, T. raschii, T. gregaria, Euphausia krohnii, and Nematoscelis megalops (listed in descending order of abundance). A high-intensity sampling scheme during November and March facilitated detailed distributional studies which revealed that M. norvegica, T. inermis, and T. longicaudata each had a specific stationary center of abundance in the study area, and each species performed a different pattern of diurnal vertical migration. Meganyctiphanes norvegica formed 90% (constituting 70 kt) of the euphausiids. The last four species were occasional immigrants from areas south of the Bay of Fundy. From the relationships between life history stages, vertical migration patterns, distribution, and currents in the Fundy Region, the authors suggest that these euphausiid species form stocks. euphausiid; crustaceans; Fundy; distribution; zooplankton; invertebrates; fauna; ecologyLacalli, T.

Periods of larval occurrence are reported for 19 polychaete species and 10 other common planktonic larvae. Egg sizes are given for 19 polychaete species with estimates of spawning period for 14 of these based on studies of the adult worms. Spawning periods are shown to correlate better with larval type (e.g. whether planktotrophic) than with the zoogeographic distribution of the adults. Among the planktotrophic larvae, the evidence suggests that some larvae (e.g. polynoid larvae) develop successfully only during the spring diatom bloom, and gamete wastage may result from any substantial mismatch between the diatom bloom and spawning period.

Seasonal aggregations of berried (ovigerous) female lobsters, Homarus americanus, in shallow water (1-22 m depth) within Flagg Cove, Grand Manan have been described. Subsequent to these surveys, a salmonid aquaculture site was approved within Flagg Cove. In response to expansion of aquaculture activity in spring 1989, and concern expressed by traditional fishing interests, SCUBA divers re-surveyed lobster populations occupying Flagg Cove during September 1989. Dives were also conducted at several other locations around Grand Manan. Lobsters were discovered in abundance in shallow water near Seal Cove, southern Grand Manan; however, there were significantly fewer berried females at this site. Further seasonal monitoring of mature lobster utilization of shallow water embayments off Grand Manan is planned for 1990. Problems associated with objectively assessing the importance of particular "breeding" sites, and determining cause-effect relationships between aquaculture development and changes in the numbers and proportion of berried female lobsters utilizing such sites, are discussed. lobsters; fisheries; aquaculture; distribution; Grand Manan; crustaceans; shellfish; invertebrates; fauna; population; Quoddy; habitatsLawton, P. and D.

Between June and November, 1990, diving surveys in shallow (<20 m water depth) inshore areas around Grand Manan documented lobster (Homarus americanus) population size and sex composition. Lobster populations occupying Seal Cove and Flagg Cove differ in size and sex composition, and in the proportion of animals in soft shell condition. Different origins of lobsters participating in seasonal movements to these areas are suggested, as well as contrasting functions; Seal Cove being used for molting purposes, Flagg Cove representing a seasonal spawning area. Surveying within Flagg Cove addressed fishermen's concern over potential effects on lobster habitat use of recently expanded salmon aquaculture activity. As compared with data from surveys undertaken in 1982, 1983, and 1989, a population displacement, away from the aquaculture site, is apparent in 1990. As well as discussing the biological significance of these distribution patterns, a rationale is presented for the focus on spatial and temporal distribution, rather than on cause: effect linkages in addressing lobster: aquaculture interaction. lobsters; fisheries; Quoddy; Grand Manan; distribution; population; aquaculture; crustaceans; shellfish; fauna; invertebrates; moultLeahy, R.

T. and S. F. Diehl (1989). "Geomechanical aspects of subsidence in eastern Maine." Neotectonics in Maine. Augusta, Maine Geological Survey Bulletin 40. 209.
Information from several sources indicates that the eastern Maine coast is subsiding. Recent releveling surveys indicate a current rate of subsidence in eastern Maine as much as 9 mm per year relative to Bangor. The anomalously rapid rise in sea level accompanying the subsidence has led to shoreline erosion, landsliding, and submergence of archaeological sites and historical manmade structures. In situ stress measurements, well-bore breakouts, and earthquake focal mechanisms show that the maximum principal stress is horizontal, strikes N 80° E, and is correctly oriented to produce thrusting on north-south faults, right-lateral motion with minor thrusting on northeast and east-northeast faults, and major thrusting with left-lateral motion on northwest-striking faults.Maximum seismicity in Maine occurs in the subsiding zone which also includes the maximum (positive) gravity anomaly in the State. Epicenters are diffusery aligned with the Oak Bay fault which strikes N 20° W.

Quantitative and qualitative analyses have been made of plankton samples collected monthly outside Passamaquoddy Bay (Prince 5) and in the St. Croix River estuary (Prince 6) for the years 1937 to 1959. Seasonal variations in zooplankton were great at Prince 5 but relatively nonexistent at Prince 6. Over-all zooplankton volumes for the period were 1.5 times larger at Prince 5. Many groups of zooplankton are seasonally abundant at Prince 5 while at Prince 6, the zooplankton is always dominated by copepods, except in April when barnacle nauplii swarm for a short time. The population dynamics of the copepods and most other zooplankters found at the Prince stations are discussed. zooplankton; Passamaquoddy; Quoddy; distribution; copepods; invertebrates; population; fauna; St. Croix; estuarineLegare, J.

Journal of Fisheries Board of Canada 17(3): 409.
Investigations of the composition, abundance, and distribution of plankton communities within the Passamaquoddy region of New Brunswick and Maine were carried out in 1957 and 1958. Studies of the food of herring and possible relationships between zooplankton abundance, feeding activity, fat content, and catches of herring were included in the program. Similar quantities of zooplankton were found outside Passamaquoddy Bay and in Cobscook Bay. Slightly smaller volumes were taken in the passages into the Bay, but only one-fifth as much was taken in samples inside Passamaquoddy Bay. Differences in zooplankton abundance suggest incomplete mixing of outside waters with those of Passamaquoddy Bay. The smallest volumes of zooplankton were taken in the spring and the largest in the summer months. Overall zooplankton volumes were much higher in 1958 than in 1957.There was evidence that herring were feeding in the upper water layers. A period of low feeding activity from March to August was followed by a period of active feeding from September to November. There was a positive correlation between feeding activity and fat content of herring but no relationship between quantities of zooplankton and feeding activity could be established. Nor was it possible to demonstrate any relationship between zooplankton volumes and catches of herring over a period of 10 years.
Higher zooplankton volumes are foreseen for Passamaquoddy Bay after the dams are built. Volumes in Cobscook Bay are expected to reach values similar to those of Passamaquoddy Bay while those outside should remain unchanged.

This volume attempts the first step in filling the need for an authoritative reference book on the fishes taken off the twenty-one thousand miles of Canadian Atlantic coastline from Grand Manan to Cape Chidley. It attempts to include reference to all official records. However, despite much effort and full cooperation by many interested people, numerous matters of fact remain unresolved and the volume must be regarded as a base from which to expand and consolidate knowledge. inventory; fish; Northwest Atlantic; fauna; vertebrates; distributionLeim, A.

Fat determinations, by ether extraction, were made on 205 samples of "sardine" herring (Clupea harengus L.)from the Quoddy region of the Bay of Fundy on the east coast of Canada. The period covered was from 1942 to 1952. The fat content was lowest in April to June and highest from August to November, with few exceptions. It varied between 1.2% and 27.5% of the wet weight of the fish. There was marked variation from year to year. Until sexual maturity was reached, the fatness increased with size. The herring were extremely fat in the winter of 1942-43 and quite poor in the next winter; a remote connection with plankton abundance is discussed. Certain regions are noted for very high fatness. A fungus disease did not greatly affect the fatness of recovering fish. herring; Fundy; feeding; growth rate; fish; vertebrates; fauna; QuoddyLeim, A. H. and L. R. Day (1959).

Juvenile stages of the marine nematomorph genus Nectonema were found in the rock crab, Cancer irroratus, jonah crab, C. borealis, hermit crab, Pagurus acadianus, and the shrimps, Pandalus montagui and P. borealis, in the Bay of Fundy. No effects on the internal organs of most parasitized hosts could be detected although some male rock crabs had atrophied gonads suggesting parasitic castration by Nectonema. In the area of highest parasite incidence 48% of the rock crabs and 11.6% of the hermit crabs sampled were parasitized with Nectonema.

The impact of organic enrichment due to Atlantic salmon (Salmo salar) farms on the benthic community in the Bay of Fundy was investigated. Monthly bottom grab samples were collected from 2 farms along 2 transects. Results from the first 8 mo showed that at site 1, a "transition zone" was established 55 m from the net-pens. At this station, species diversity and biomass peaked. High numbers of Capitella and high microbial biomass were detected at the station closest to the cages, indicating that organic enrichment had occurred in the vicinity of the farm. At site 2, no trends were evident when species diversity, abundance and biomass curves were compared with respect to distance from the farm. At the station closest to the cages, however, there was a significant increase in the number of Capitella. salmon; aquaculture; bacteria; Fundy; vertebrates; fisheries; fauna; benthicLinkletter, L.

From a study of living materials and specimens in several regional herbaria, a list has been drawn up of all the common and several of the rarer tube-dwelling diatoms of eastern Canada. Descriptions, illustrations of living material and acid-cleaned valves, and a key to the species are provided. Most specimens were from the Atlantic Provinces and the St. Lawrence Estuary, but a few were from the Northwest Territories. By far the most common species is Berkeleya rutilans. Other species occurring commonly in the Quoddy Region of the Bay of Fundy, and sporadically in space and time elsewhere, are Navicula delognei (two forms), Nav. pseudocomoides, Nav. smithii, Haslea crucigera, and a new species, Nav. rusticensis. Navicula ramosissima and Nav. mollis in eastern Canada are usually found as scattered cohabitants in tubes of other species, Nitzschia tubicola and Mz. fontifuga also occur sporadically as cohabitants. inventory; diatoms; Quoddy; Northwest Atlantic; Quoddy; flora; algae; phytoplankton; estuarineLocke, A. and S.

More than 106 families of insects representing 12 orders, spiders, mites, and millipedes were collected in the neuston of the Bay of Fundy in spring, summer, and autumn. Homoptera, Diptera, and Hymenoptera were dominant in number of families and (or) number of individuals. Seasonal annual variations in taxonomic composition and in abundance were considerable. The abundant detritus of terrestrial and fluvial origin in the neuston, especially in summer, may be a potentially important food source for surface-feeding animals. inventory; invertebrates; Fundy; fauna; terrestrialLocke, A. and S.

The taxonomic composition and geographic distribution of Euphausiacea and Decapoda occurring in the neuston were examined in spring, summer and autumn surveys of a 2.4 x 104 km2 area of the Bay of Fundy. Adult Meganyctiphanes norvegica and Thysanoessa inermis (Euphausiacea) were present in every survey and were most abundant in autumn. Larval euphausiids were most abundant in summer but were also present in spring and autumn. Adults of three natantian decapod species were rarely collected; however, larval Natantia were common in summer and autumn. Larvae representing seven genera of reptantian decapods were collected in summer and autumn; the most abundant was Cancer sp., which was numerically dominant in summer samples. Distributional patterns divide the taxa into inner and outer bay components at a line drawn between Digby, Nova Scotia and St John, New Brunswick, corresponding to the boundary of the major counterclockwise gyre in the Bay of Fundy.

Six species of isopods and 18 species of amphipods were collected in the neuston of the Bay of Fundy and adjacent waters. Amphipods and isopods reach the neuston of the Bay of Fundy in three ways. Idotea metallica, the only euneustonic species present, was probably advected into the Bay of Fundy from southern waters in summer, and did not appear to overwinter in the Bay. Most species, including I. baltica, were collected with drifting littoral vegetation, and we suggest that transport by surface currents is an important factor in dispersal of some shoreline crustaceans. Midwater plankton, such as Parathemisto gaudichaudi, reached the neuston either by advection in upwelling waters or by an extension of their normal diel vertical distribution. distribution; Fundy; currents; crustaceans; zooplankton; invertebrates; fauna; circulationLogan, A.

No abstract available. From the introduction to Chapter 8. Sublittoral had substrates occur extensively in shallow coastal waters in the western part of the Bay of Fundy, particularly on the northwest shore; they are usually coincident with rocky or cliffed shorelines of resistant rocks, where the dominant destructive agent is subaerial weathering rather than marine erosion. Under these conditions rock rubble, ranging from boulder to pebble size, falls to the base of the cliff and forms a relatively steep zone of submerged rock debris, grading seawards into sand and mud at depths beyond about - 30 m. Occasionally, submarine rock outcrops may occur as jutting "ledges", exhibiting both inclined and vertical faces, depending upon the attitude and joint directions of the rock stratum. Isolated hard substrates also occur in some deeper water areas, where coarse relict glacial tills have remained free of mud due to strong bottom currents (Fader et al. 1977). geology; Quoddy; subtidal; rockyLogan, A. and J.

Three locations were selected for detailed study of the epibenthos of sublittoral hard substrates in the Deer Island region of the Bay of Fundy. A total of 10 transects, using photographic and quadrat methods, yielded data on precentage coverage, density and diversity of biota in relation to depth. The mid-depth zone has a mean depth of 10 m. The zone is characterized by higher species richness; greater coverage of sponges, bryozoans and hydroids; lower densities of sea urchins and limpets; and less areal coverage by encrusting algae. The cliff-face cluster is characterized by enrichment of bryozoans, anemones, sponges and brachiopods. The deep zone has a mean depth of 18 m, and is animal-dominated, supporting the greatest species richness, with sponges, hydroids, anemones, brachiopods and tunicates common, but algal coverage much reduced. zonation; ecology; Fundy; diversity; subtidal; benthic; invertebrates; flora; faunaLoring, D.

Total Zn, Cu, Pb, Co, Ni, Cr, V, Hg, Be, As, Ba, and Se concentrations vary regionally and in response to textural variations of the sediments of the Bay of Fundy. They are, except for local anomalies, at or near natural levels in relation to their source rocks and other unpolluted marine sediments. Chemical partition indicates that small but significant amounts (1-27%) of the total element concentrations are potentially available to the biota. Potential bioavailable metals are derived from natural and industrial sources and are held in the sediments by fine grained organic material (Hg, Pb), hydrous iron oxides (Cr, V, Co, Pb), ion exchange positions (Zn), and calcareous components (Cu, Zn, Ba). Of the total metal content, however, 73-99% is not readily available to the biota but held in various sulphide (Zn, Cu, Pb, As, Se), oxide (Cr, Ni, Co, V), and silicate minerals (Cr, V, Co, Ni). metals; toxins; Fundy; sediments; nutrientsLoucks, R.

Dispersion of spilled oil would be rapid and extensive in the Head Harbour Passage. The risk of contamination seems to be general rather than concentrated in a few 'collector-sites.' Thus all the waters and shores of the Passage would be vulnerable to contamination within 12 hours of a spill there. Waters and shores of Passamaquoddy Bay, Campobello and Grand Manan would be vulnerable to contamination within a week. Waters and shores of the Bay of Fundy and Gulf of Maine would be vulnerable to contamination with longer delays.

No abstract available. From the introduction.On Dr. McBride's suggestion I went to St. Andrew's station, intending to do some work on the early development of the egg of the herring, and allied food fishes, found in that locality. As the season wore on I found it would be impossible for me to do any work on this problem, owing to the lateness of the spawning this year. At time of writing (August 29) even, very few, if any 'ripe' herring have been observed by the fishermen among those captured in their weirs. Accordingly Dr. Stafford, the curator of the station, suggested that I should do some systematic work on the crustacea, and the following are the forms obtained during the few weeks devoted to the work by me.
Material was obtained by collecting at low tide and by dredging in the waters from Dochet Island to Grand Manan. crustaceans; Passamaquoddy; Quoddy; inventory; fauna; invertebrates
MacDonald, J. S., M. J. Dadswell, et al. (1984). "Fishes, fish assemblages, and their seasonal movements in the lower Bay of Fundy and Passamaquoddy Bay, Canada." Fish. Bull. 82: 121.
Five fish assemblages, dominated by pleuronectids, cottids, gadids, clupeids, and rajids, were identified from collections taken during a 5-year survey in the lower Bay of Fundy region, Canada. Individual assemblages occurred in each of estuarine, beach, pelagic, and offshore hard- and soft-bottom habitats. Species and/or age-class components within assemblages varied seasonally but, in general, each assemblage was distinct. There was a progressive seaward displacement of these assemblages from shallow, inshore to deeper, offshore habitats in winter followed by a reversal during summer. Yearly changes in species occurrence and abundance during the study period were predominantly attributable to variation in ocean climate. Long-term changes in abundance of two commercial species at one of the sampling sites, since a similar study there in 1965, appear related to population fluctuations in the Bay of Fundy and the Gulf of Maine. The beach habitat apparently served as a major nursery area for juvenile gadids, pleuronectids, and clupeids.

Information redundancy associated with three measurement variables were examined using food habit data from five species of demersal fish in the lower Bay of Fundy. Number, weight, and percent frequency of occurrence measures of three prey species all load heavily on the first principal component of a PCA and are therefore highly correlated. It is concluded that it is probably not necessary to create compound indices of prey species importance when documenting soft-bottom benthic associations or demersal fish food habits. Compound indices add little new information when compared with any single measure. fish; feeding; nutrition; Fundy; ecology; vertebrates; faunaMacDonald, J. S. and R. H. Green (1986).

Feeding relationships of various fish species, and their relationship to the composition of the surrounding sediments, were observed for 1 yr at two sites in the lower Bay of Fundy region. The fishes were the ocean pout (Macrozoarces americanus, Zoarcidae), winter flounder (Pseudopleuronectes americanus, Pleuronectidae), plaice (Hippoglossoides platessoides, Pleuronectidae), cod (Gadus morhua, Gadidae), and witch flounder (Glyptocephalus cynoglossus, Pleuronectidae). After reducing the size of the data matrix by removing redundant variables, the authors used discriminant function analysis to assess interspecific diet overlap and the degree to which stomach contents reflect benthic composition.

Stomachs of ocean pout (Macrozoarces americanus), Atlantic cod (Gadus morhua), winter flounder (Pseudopleuronectes americanus), and American plaice (Hippoglossoides platessoides) were removed and dissected 5, 12, 20, and 30 h after the fish had fed voluntarily to test the evacuation rates of three different prey species. Two evaluation procedures were used: a visual index of recognizability, and a graphical analysis of percent of each prey recovered versus time since feeding. Three decay models were tested for goodness of fit to the evacuation data. The polychaete worms were the first to become unrecognizable, followed by amphipods. These species showed significantly different rates of evacuation when compared with the bivalves which were recognizable for the longest time. The exponential decay curve gave the best overall fit to the data. However, a linear model gave a good or better fit to the decay rate of the bivalve. The evacuation rates of different prey should be considered in estimating daily rations of fish in their environment. feeding; nutrition; fish; Northwest Atlantic; vertebrates; faunaMacFarlane, C.

These rivers include the Dennys, Machias, East Machias, Narraguagus and Pleasant Rivers in Washington and Hancock Counties and the Ducktrap and Sheepscot Rivers in Lincoln, Kennebec, Sagadahoc, Knox and Waldo Counties. The Plan builds upon the strong foundation of Maine's long-standing commitment to restoration of salmon to natal habitat in order to identify the needs of the species. But the Plan and its implementation breaks new ground with a key innovation: a comprehensive review of the watersheds by a team of citizens (who know and use the resources in the watershed) to fashion a systematic plan to minimize adverse human impacts on the species and restore salmon through a series of reasonable and affordable measures. Maine believes that this collaborative and innovative approach to protection and restoration of salmon is vital to maintaining the commitment of Maine citizens to this important natural resource. Importantly, the Plan includes a novel restoration project for these salmon runs using the expertise of Maine's salmon aquaculture industry, a project that may serve as a model for future restoration efforts.

The grey seal in eastern Canada, Can. Fish. Mar. Serv. (No. 704).
The grey seal is widely distributed in eastern Canada with major breeding colonies at Sable Island and on the ice in the southern Gulf of St. Lawrence. Current estimated pup production is about 6400 and total population about 24,000. The population appears to be expanding steadily, resulting in increased predation of inshore fisheries for several species of commercial importance. Since controlled killing by the Federal Government has not halted this population increase, a bounty has been introduced to provide some measure of local control, but its effectiveness cannot be determined as yet. The grey seal is final host to a nematode parasite, the so-called codworm, which infests the flesh of commercially important groundfish. Recent analyses suggest that the grey seal is the predominant vector of this parasite in eastern Canada. seals; marine mammals; vertebrates; fauna; Northwest Atlantic; population; parasites; fisheries; pinnipedsMaranda, L., D.

Isolates of the dinoflagellate Gonyaulax tamarensis were established from benthic cysts or motile cells collected along the north-western Atlantic coast from the Bay of Fundy to Long Island. All clones were grown under the same conditions and assayed in a blind test for toxin content and composition. Differences in toxin content (mu mouse unit per cell) spanning two orders of magnitude were found, with decreasing toxicity from north to south. Some isolates had undetectable toxin levels. The low toxicity of southern strains of G. tamarensis may explain the historical absence of paralytic shellfish poisoning (PSP) in areas where cysts and motile cells have been reported. The cause of the observed geographic pattern is unknown, but it does suggest that there may be an environmentally-determined southern limit to the regional PSP problem.

A study into the feasibility of culturing Atlantic and pink salmon in sea cages: final report to the Department of Fisheries and Oceans, Marine Research Associates, St. Andrews, New Brunswick, St. Andrews, New Brunswick: Marine Research Associates.
An attempt to grow Atlantic salmon and pink salmon in sea cages at Deer Island New Brunswick was undertaken by Marine Research Associates for the Department of Fisheries and Oceans. The company was to, 1) document growth and mortality of these species in relation to environmental parameters, diet formulation and disease problems, 2) assist the Department of Fisheries and Oceans in the evaluation of the comparative cost and nutritional value of commercial dry foods and experimental moist foods, 3) assist the department in the evaluation and development of vaccines, 4) work towards the advancement of technology for the over-wintering of salmonids through cage design modifications and evaluation, 5) evaluate the feasibility of utilizing Atlantic salmon and pink salmon for commercial sea farming in the Bay of Fundy through analysis of research and marketing results and cost monitoring, 6) collect and store data on the following environmental parameters: water temperature, salinity, water quality (general observations), weather, boat traffic, fouling of nets, tides and currents, other parameters and operational activities, 7) compare costs and nutritional value of commercial dry pelleted food and moist food produced on the site, 8) carry out a market search over the life of the project and 9) obtain all necessary permits and licenses to insure the success of this operation.

(1982). "Identification of larval and juvenile Canadian Atlantic gadoids with comments on the systematics of gadid subfamilies." Canadian Journal of Zoology 60: 3420.
An attempt to identify larvae and juveniles of Gaidropsarus led to a broader survey of gadoid morphology. Representative specimens of all gadoid families and all Canadian Atlantic gadid species were examined for selected morphological characters. The polarity of these character states was examined using a cladistic approach and led to the conclusion that the gadids are composed of three groups, recognized herein as subfamilies: Gadinae, Lotinae, and Phycinae. The most informative structure examined was the caudal skeleton, which showed three characters with an obvious primitive state in some gadids: presence of X and Y bones, 6 "primary" caudal fin rays, and low (<40) total caudal fin ray counts. Dorsal fin structure, which has been the basis of previous gadid systematic arrangements, is also shown to be informative, providing good evidence of relationship within gadines and phycines. The proposed groupings receive some additional support in the gross morphological similarity of their larvae. cod; fish; vertebrates; fauna; Northwest AtlanticMarkle, D. F., D. A. Methven, et al.

Canadian Journal of Zoology 60: 2057.
The amount of coexistence in the sympatric sibling species. Urophycis chuss and U. tenuis, appears to be a function of ontogeny, with each life history stage showing different probabilities of interspecific encounters. Demersal juveniles coexist the least since U. chuss is inquiline with scallops and U. tenuis is in nearshore shallows. In U. tenuis there is also intraspecific segregation, with older juveniles and young adults bathymetrically segregated from the youngest demersal juveniles in summer.Relatively more coexistence is seen between neustonic juveniles. However, they show some seasonal and pronounced diel differences in availability to neuston nets (U. chuss predominates during the day and U. tenuis during night). The greatest coexistence is seen between adult U. chuss and adolescent to adult U. tenuis
Over its life, U. tenuis tends to move into deeper water while U. chuss is relatively stenotopic, its distribution largely a reaction to temperature. The life history strategy of U. tenuis is "get big quick" a goal achieved, in part, through delayed maturation (relative to U. chuss). The strategy of U. chuss seems to be avoid predation, concentration growth in the juvenile stage, and "get mature quick." We speculate that both species' life histories may be subordinate to getting the demersal juveniles into the right nursery area at the right time. fish; vertebrates; fauna; distribution; Northwest Atlantic; ecology; life history

The 1984 Atlantic salmon (Salmo salar) run on the Magaguadavic River, New Brunswick, monitored at the St. George fishway numbered 767 fish (512 multi-sea-winter salmon and 255 grilse). The alewife (Alosa pseudoharengus) run was estimated at 43,720 plus or minus 8665 fish within 95% confidence limits. Biological data for the 1984 and 1985 alewife spawning runs are presented. Timing of runs of alewives and salmon passing through the fishway was similar to 1983 and could serve as a guideline to schedule fishway maintenance. Observations on fish use of a newly installed downstream bypass sluice and predation by gulls are also presented. Cannibalism of emigrating juvenile alewives by subadults in the estuary was considered a major source of mortality. fisheries; predation; Passamaquoddy; Quoddy; salmon; alewives; anadromous; hydropower; predation; vertebrates; faunaMartin, J.

Circumstantial evidence is presented that domoic acid detected in softshell clams Mya arenaria and blue mussels Mytilus edulis from the southwestern Bay of Fundy, eastern Canada, during July to October 1988 was obtained by feeding on the pennate diatom Nitzschia pseudodelicatissima. This microalga was the most abundant organism observed in weekly samples collected at the surface, 10 m depth and bottom from nearly all of the 18 locations sampled during the same period. Phytoplankton net hauls consisting principally of N. pseudodelicatissima contained levels of domoic acid up to 3.5 mug g-1. Isolates of 9 dominant phytoplankton species occurring in the southwestern Bay of Fundy during July to October 1988 were cultured and tested for the presence of domoic acid; only N. pseudodelicatissima cultures produced the toxin at concentration of 7.0 x 10-15 to 9.8 x 10-14 g cell-1. molluscs; invertebrates; fauna; Fundy; feeding; diatoms; toxins; phytoplankton; shellfish; floraMartin, J.

Water samples were collected for five consecutive summers (1980-84) in the Bay of Fundy at the surface and at 5 m to examine the distribution patterns of the motile stages of the toxic dinoflagellate Gonyaulax excavata, which has caused shellfish toxicity in this area for years, as well as occasional fish kills. In 1980 and 1981, 128 and 122 stations were sampled, respectively, and 84 and 41% of the samples contained G. excavata cells. Results suggest the prevailing circulation in the Bay and the presence of tidal fronts are dominant factors in retaining G. excavata and its life cycle stages in the south-central and southwestern portion of the Bay and that this accounts for its perennial occurrence in this area. toxins; paralytic shellfish poisoning; dinoflagellates; phytoplankton; Fundy; distribution; floraMartin, J.

Soft-shell calms, Mya arenaria, were collected from two sites in the southwestern Bay of Fundy in January, April, May, July, September and November, 1986. The sites were Crow Harbour, where clams exceed the quarantine toxin level year-round, and Lepreau Harbour, where clams exceed the quarantine level only during the annual, summer Alexandrium bloom. Clams were dissected into digestive gland, gonad, gills, muscles (siphon, foot, pallial muscle and adductor muscle), and "remainder" which consisted of a small amount of material near the digestive gland and included the kidney, heart and brown gland. The concentration of total toxins ( mu g STX equiv./100 g) in the "remainder" was up to 10 times greater than in the other tissues throughout the year except in July. Also: Martin, J.L., A.W.

Algal blooms have been responsible for substantial losses to farmed fish in Europe, South America and western Canada. As a result of the increased use of coastal waters in the southwestern Bay of Fundy for salmonid aquaculture, an environmental study was begun in 1987 to establish a database and to monitor phytoplankton populations. Although by 1990 there had not been any salmonid mortalities linked to algal blooms in the Bay of Fundy, microalgae have been identified that have caused mortalities elsewhere in the world, such as: Alexandrium fundyense, Chaetoceros convolutus and Gyrodinium aureolum. algae; salmon; aquaculture; Fundy; phytoplankton; dinoflagellates; diatoms; fish; vertebrates; fauna; flora; seaweedMartin, W.

It is predicted that the construction of power structures will have no measurable effect on Charlotte County groundfish landings as a whole. It is expected that the 1,700,000 lb or 12% of the Charlotte County groundfish catch, taken in 1958 inside the dam sites, will be greatly reduced. Specifically, it is forecast that the pollock line fishery in Head Harbour Passage, which yielded 1,500,000 lb in 1958, will be greatly reduced, the haddock dragger fishery will be reduced or eliminated in the high pool, and the flounder fishery in Passamaquoddy and Cobscook Bays will probably increase. tidal power; fisheries; Passamaquoddy; QuoddyMathieson, A.

The present account gives a comparative phytogeographic evaluation of the seaweed populations at 15 northwest Atlantic sites, ranging from Woods Hole, Massachusetts, to South Wolf Island, New Brunswick. Major emphasis is placed upon the floristic affinities of the Isles of Shoals, an archipelago of eight offshore islands in southern Maine and New Hampshire. The pattern of seasonal occurrence of seaweed populations at the Shoals (i.e., eight islands combined) showed a pronounced summer maximum (150 taxa) and a winter minimum (77 taxa). A similar pattern was recorded for five other northwest Atlantic sites, with the southernmost location (Woods Hole) exhibiting the highest ratio of annual/perennial taxa (1.29) and all of the more northern sites, except Campobello Island, exhibiting ratios of <1.0. In contrast to the low floristic similarities of the southern California Channel Islands (x = 45.4%), all 15 northwest Atlantic sites had much higher floristic affinities (x = 71.9%). seaweed; Gulf of Maine; distribution; algae; floraMavor, J.

The object of the present series of investigations has been to determine what, if any, general movement of the water other than the tides occurs in the Bay of Fundy. The movement of sea water made evident in the tides is always of the nature of an oscillation, whether it be the rise and fall seen on all shores, or the flow to and fro seen in tidal streams. Such an oscillatory movement does not produce a constant flow in one direction and does not lead to any continuous translation of the water. It may often be in fact that the flow and ebb of the tidal streams in a given region obscure a slower but continuous movement of the water in one direction not due to the tidal force. The importance of such continuous movements in any consideration of the life history of marine organisms is obvious as eggs, larvae or post-larval stages may be transported far from the place of breeding to waters either suited or unsuited to their survival. circulation; Fundy; tides; currents; oceanography; hydrographyMcCollough, M. A. (1981). The feeding ecology of migratory semipalmated sandpipers, short-billed dowitchers, semipalmated plovers, and black-bellied plovers on staging areas in Eastern Maine, M.S. Thesis in Wildlife Management, University of Maine at Orono.
The feeding ecology of semipalmated sandpipers (Calidris pusilla), short-billed dowitchers (Limnodromus griseus), semipalmated plovers (Charadrius semipalmatus) and black-bellied plovers (Pluvialis squatorola) was studied on coastal staging areas in eastern Maine during their southward migration, July-September, 1980. Marine oligochaetes, polychaete worms (Nereis virens and Clymanella torquata) and amphipods (primarily Corophium volutator) were the major prey items of semipalmated sandpipers and short-billed dowitchers. Semipalmated plovers and black-bellied plovers ate mostly polychaete worms (Nereis virens), gastropods (Littorina sp. and Hydrobia sp.), isopods (Chiridotea coeca), and amphipods (Gammarus oceanicus and Corophium volutator). Shorebird diets varied between feeding areas and generally overlapped broadly by prey taxon taken.Only semipalmated plovers showed a significant numerical response to the density of their major prey on study plots. Shorebird foraging rates (pecks and probes per min) were not correlated with prey density. Short-billed dowitchers, semipalmated plovers, and black-bellied plovers captured more prey on areas where their prey were most numerous. These observations were consistent with the hypothesis that shorebirds would be most abundant in areas of high prey density because the number of prey captured is greatest in such areas.
Changes in the June-September density of potential invertebrate shorebird prey ranged from a 39% increase for Corophium volutator to a 84% decrease for Gammarus oceanicus. Some invertebrate taxa (Nereis virens, marine oligochaetes, Hydrobia sp., Littorina sp., and Gammarus oceanicus exhibited a density-dependent change in density. These changes were assumed to have been in response to numerical and functional behavior of shorebirds. Results of exclosure experiments to prohibit shorebird feeding were too variable to make valid conclusions about invertebrate population changes in the absence of shorebird predation. Evidence from this study indicates that invertebrate prey are plentiful in eastern Maine throughout the migratory season. The transitory nature of shorebird migration was apparently short enough to inhibit a largescale depletion of intertidal invertebrates.
Supplement Abstract:
Shorebirds (Charadriiformes) were censused on coastal staging areas in eastern Maine during northward (April-June) and southward (July-September) migrations in 1980. Twenty-five species of shorebirds were recorded. Maximum numbers of semipalmated sandpipers (26,174), short-billed dowitchers (761), semipalmated plovers (1,783), and black-bellied plovers (2,066) were recorded during July and August on 10 feeding and 10 roosting areas. Mud flats in the Eastport, Lubec, and Machias Bay areas supported the highest number of shorebirds. High tide roosts at Lubec and Sprague Neck (Machias Bay) were most heavily used. These data confirm that the coastal area in eastern Maine is of major importance to shorebirds especially during their fall migration. shorebirds; birds; Quoddy; feeding; migration; food web; invertebrates; inventory; benthic; fauna; vertebrates; predation; mudflats
McCollough, M. A. (1986). Post-fledgling ecology and population dynamics of bald eagles in Maine, Doctoral Dissertation in Wildlife, University of Maine at Orono.
Photographs of 135 wintering bald eagles (Haliaeetus leucocephalus) of known age from Maine were examined to document plumage changes. Criteria were established to age 1/2-year (Juvenal plumage), 1 1/2-year (Basic I), 2 1/2-year (Basic II) and 3 1/2-year (Basic III) eagles primarily from head plumage and iris, beak, and cere color. Body plumage varied between individuals and was not a reliable aging characteristic. Definitive plumage was observed in some 4 1/2-year (Basic IV) and all 5 1/2-year (Basic V) eagles. However, individuals were observed with gray or brown flecking in the head plumage up to 8 1/2 years-of-age. Photographs of wintering eagles demonstrated that yearly body molt is not complete.A winter feeding program for bald eagles was conducted in Maine during 1981-1985. Over 98,000 kg of carrion were distributed to feeding stations in 4 major eagle wintering areas. Numbers of individual eagles using the feeding stations increased from 66 in 1981-82 to 274 in 1984-85. Observations of 203 different banded eagles indicated that the wintering birds were primarily from Maine and the Canadian Maritime Provinces. First- and second-year eagles depended on the feeding stations for most of their winter diet and older eagles used the feeding stations less frequently. Dispersal of first-year eagles probably decreased as a result of feeding. Average regional productivity did not increase but local production near feeding sites was enhanced. Energetics of feeding, feeding interactions with corvids, and management implications are also discussed.
Resightings of 195 banded bald eagles at winter feeding stations in Maine from 1981-85 enabled calculation of survival estimates. Survival of first-year, second-year, and older eagles was 73%, 84% and 9l% respectively. Minimum age-specific survival estimates for eagles before feeding were 54%, 79% and 91%. Survival was much higher than previously reported and may have increased by as much as 18% for 1-and 2-year eagles as the result of winter feeding. Survival and productivity data indicate that Maine's bald eagle population should increase from 84 nesting pairs in 1981 to over 150 nesting pairs by the mid-l990's.
Eighteen young bald eagles in eastern Maine were observed from fledging to dispersal from their natal area. Young eagles stayed with their parents from 35 to 67 days before dispersing and relied entirely on their parents for food (primarily fish during this period). Home ranges of young eagles during the post-fledgling period were smallest for island nest sites (X = 8 ha) and largest (X = 69 ha) for interior nest sites. Young eagles used primarily large, supercanopy white pines (Pinus strobus) and spruces (Picea sp.) for perch sites and perched near the nest or in adjacent forested riparian habitats. From 30-60% of the 1982-85 cohorts initiated a long distance dispersal along the Atlantic seaboard during their first winter. Most of the eagles returned to Maine by their second winter. By their second summer young eagles were adept at capturing their own food and wandered throughout eastern Maine and western New Brunswick.
Retention rates of plastic color bands, anodized rivet bands, vinylcoated nylon band tags, and U.S. Fish and Wildlife Service rivet bands were determined by repeated observations of 157 triple-banded bald eagles at winter feeding stations in eastern Maine. Plastic color bands had the greatest loss rates and were removed by all birds by their fourth winter. Band tags, anodized rivet bands, and USFWS rivet bands were recommended as good markers for identifying individual bald eagles if the anticipated distance between observers and marked eagles is consistently <100m. Resightings of color-marked eagles has increased the proportion of Maine eagles reobserved from 8.2% to 56.3% and enabled the calculation of survival estimates.

From 1954 to 1957 haddock within Passamaquoddy Bay have been of intermediate sizes. Few small fish or large fish have been captured either by commercial fishermen or in small-mesh research nets. Tagged fish of the Passamaquoddy Bay region moved out of the Bay during winter and mingled mainly with haddock stocks off the New England States. In the following summer recaptures of tagged fish were again most numerous within Passamaquoddy Bay. Stocks of haddock within the Bay appear to result from annual migrations into the Bay in early summer. It is predicted that the proposed power structures would have no effect on haddock stocks outside the high and low pools but that they would probably seriously reduce the haddock population within the high pool. fish; Passamaquoddy; haddock; fisheries; population; tidal power; Quoddy; vertebrates; fauna; distributionMcCracken, F. D. (1963). "Seasonal movements of the winter flounder, Pseudopleuronectes americanus (Walbaum), on the Atlantic coast." Journal of Fisheries Research Board of Canada 20: 551.
Winter flounders occur from Labrador to Georgia and yield large catches off southern New England. This paper relates their distribution and seasonal movements to environmental factors.In spring immature and mature flounders are alongshore with spawning fish concentrated in shallow water. During "summer", winter flounders leave the shore zone in areas where water temperatures rise above about 15° C but not where bottom temperatures do not reach this level. This movement toward cooler water does not continue into depths at which temperature is below about 12° C. Flounders return to the shore zone in fall after temperature decreases below 15° C. These temperatures are well below the upper incipient lethal for flounders of about 26° C.
Flounders remaining alongshore in summer are distributed in depth according to size and maturity. Small, immature fish are in the shallowest water, the region of highest light intensity, immatures of medium size deeper, and mature fish in both regions. Under experimental conditions immature fish of medium size moved into shade at lower light intensities than either small immatures or large matures.
North of Cape Cod flounders move deeper in "winter" as the shallow water becomes colder than the deeper. To the south, spawning condition is reached earlier and mature flounders remain in shallow water during the cold-water period.
Off southern New England, a large, sustained fishery denotes a large population of flounders. In the Bay of Fundy and off the coast of Nova Scotia winter flounders are restricted to a narrow depth zone, and good exploratory catches there probably do not indicate large populations. In the broader shallow zones of the southern Gulf of St. Lawrence similar catches suggest a larger population. Exploitation will depend on increased efforts by small otter trawlers or possible development of marine sport fishing.

From June 20 to November 21, 1957, 87,495 herring were tagged in the southern part of the Bay of Fundy and Gulf of Maine. These fish were immature and ranged in total length from 14.0 to 18.7 cm. and in age from 1 to 3 years. Recovery of 792 (2.1%) tagged individuals indicated that the herring moved in and out of Passamaquoddy Bay throughout the summer and early autumn. No interchange of herring took place between Passamaquoddy Bay and the coast of Maine or Nova Scotia. Herring moved into Passamaquoddy from as far south as Grand Manan Island and as far east as Point Lepreau. The greatest straight-line distance moved was 55 miles, the mean time before recapture was 12 days, and the longest time 82 days.

Analyses of weir catches show no significant relationships between average catches inside Passamaquoddy Bay and catches in outside areas for the same year. Weirs inside Passamaquoddy Bay are more efficient and catch about twice as many herring per weir as those outside the Bay. Seasonal and annual variations both in individual weir catches and in total catches in the various statistical districts of Charlotte County are far greater now than any changes that can be forecast as resulting from the installation of the proposed Passamaquoddy tidal power dams. herring; Passamaquoddy; tidal power; fisheries; Quoddy; vertebrates; faunaMcKenzie, R.

During 1957 and 1958, 137,469 herring were tagged in the southern part of the Bay of Fundy and the western part of the Gulf of Maine. These fish were immature and ranged in mean total length from 9.9 to 20.0 cm and in age from 1 to 3 years. Recovery of 3,582 (2.6%) tagged individuals showed that herring moved in and out of Passamaquoddy Bay irregularly throughout the summer and autumn with some tendency to concentrate at the head of this bay. Outward movement reached a peak in July when there was a considerable movement eastward towards Point Lepreau. Herring moved into Passamaquoddy from as far south as Grand Manan and from as far east as Point Lepreau. Little interchange of herring took place between the Passamaquoddy area and the coasts of Maine and Nova Scotia. The greatest straight-line distance from release to recovery points was 55 miles. More than half of the recaptures were made within 2 miles of the tagging sites and nearly two-thirds within 5 miles. About 28% of the recaptures were made within 1 week after tagging and 63% within 2 weeks. The average time before recapture was 12 days in 1957 and 17 days in 1958. The longest time between release and recapture for both years was 165 days. Drift bottles released with tagged herring showed no apparent relationship between herring movements and surface drift. The results of tagging support a general conclusion that the proposed Passamaquoddy tidal power structures will have no significant effect on the herring fisheries of the Passamaquoddy area. herring; fisheries; Gulf of Maine; Passamaquoddy; tidal power; Quoddy; vertebrates; faunaMcLeese, D. W. and D. G. Wilder (1958). "The activity and catchability of the Lobster (Homarus americanus) in relation to temperature." Journal of Fisheries Research Board of Canada 15(6): 1345.
The activity (walking rate) of lobsters acclimated to various temperatures increased from 2 to 10° C. and from 20 to 25° C, but was constant between 10 and 20° C. Lobsters acclimated to low temperatures were most active above the acclimation temperature. Those acclimated to intermediate and high temperatures were most active at the acclimation temperatures. Experimental fishing of a relatively constant stock showed that the catch per 100 standard trap hauls (index of catchability) was linearly related to temperature. Slope of line is, however, dependent on stock density. Catchability is shown to be proportional to activity minus a constant. This relationship permits use of catch per unit effort and accumulated catch data to estimate lobster populations. lobsters; fisheries; temperature; crustaceans; Northwest Atlantic; invertebrates; shellfish; faunaMcLeese, J.

Winter flounder (Pseudopleuronectes americanus) from Passamaquoddy Bay, New Brunswick undergo an annual fast from November to May which results in a decrease in the slope of the length-weight relationship, in the condition factor, in the liver and white muscle lipid contents, and an increase in muscle water content. Winter flounder appear to have sufficient lipid reserves to support the winter fast, as muscle water content declined only at the onset of feeding. We propose that the continued need for salt and water transport for osmoregulation maintains the proximodistal gradient of mass and surface area and ameliorates the effect of starvation on mucosal mass and area. flounder; Passamaquoddy; feeding; Quoddy; fish; vertebrates; fauna; nutritionMcLellan, H. J. (1958). "Energy considerations in the Bay of Fundy." Journal of Fisheries Research Board of Canada 15: 115.
Following developments of Taylor, Allard and Redfield, the rates at which energy is dissipated in the Bay of Fundy in various ways are calculated. A total of 30.9X106 kw. is transmitted into the bay, of which 1.26X106 kw. is transmitted into Passamaquoddy Bay. Work is done on the moon at the rate of 2.18X106 kw. and 0.03X106 kw. is used to maintain the mixed state in the waters of the Bay of Fundy. The remaining 27.lxl06 kw. must be dissipated by tidal friction. This value is compatible with the usual concepts of turbulent flow over a rough surface if the "roughness length" (20) is equal to 0.4 cm. or the average size of the roughness elements (E) is about 11 cm.The effect which the extraction of additional power from the system would have on tidal ranges is evaluated. The range at the head of the Bay of Fundy would decrease at the rate of 0.84 foot (26 cm.) for each million kilowatts. The proposed Passamaquoddy Project would probably increase the mean tidal range at Hopewell Cape by 0.6 foot (18 cm.) tidal power; hydrography; oceanography; Passamaquoddy; Quoddy

Three distinct fault-bounded litho-tectonic units have been recognized on Campobello Island in southern Passamaquoddy Bay. These units are the Upper Silurian Wilsons Beach beds, the Lower Silurian Quoddy Formation and the Upper Precambrian Coldbrook Group. Contact relationship between these units and their correlations in the Passamaquoddy Bay area resolve correlation problems between coastal Maine and New Brunswick, and demonstrate the nature of the junction between the Avalon Platform and the Acadian mobile belt. These faults formed along pre-existing zones of crustal weakness that were generated during the late Precambrian by major strike-slip faulting. The present geological configuration of the area was basically established by episodic reactivation of northeast-trending faults (high-angle reverse movements) during the compressional regime of the Acadian Orogeny.

Introduction:In carrying out a qualitative study of the plankton of Passamaquoddy Bay with the object of determining its seasonal variations a number of interesting forms were observed, some altogether new and others hitherto unrecorded from the Eastern Atlantic. A record of certain of these forms seemed desirable, even although the information concerning them was by no means complete, and the present paper is an account of certain adult and larval Crustacea, all of which present features of interest. crustaceans; Passamaquoddy; zooplankton; invertebrates; fauna; Quoddy

No abstract available. From the introduction:With the object of determining the general character of the winter plankton in the vicinity of the Biological Station, St. Andrews, New Brunswick, the caretaker of the station A.B. Calder, was instructed to make collections of the plankton during the winter of 1914-15 and to preserve the material collected in formalin. Collections were consequently made at frequent intervals from the latter part of September, 1914, until the end of May, 1915, and in what follows, the results of a qualitative study of the collections are given. Acknowledgment must be made of the conscientious manner in which Calder fulfilled the task with which he was entrusted, the collections having been made with sufficient frequency to give an excellent idea of the character of the winter plankton, and the material being well preserved. Two collections were taken at each station in the majority of cases, one at the surface and one at a depth of about 6 metres (3 fathoms), and at each station the temperature of both the air and the surface-water was taken, and the condition of the tide noted. The only misfortune that occurred was the loss of the labels of some of the collections, chiefly of those made in the early autumn, so that these collections cannot be included in the table which forms an appendix to this report. Their omission, however, does not modify the qualitative character of the plankton as shown by the remaining collections. In studying the collections, the volume of the material contained in each one was measured, and since nets of the same mesh were used throughout and the time of the towing was the same, i.e., twenty minutes for each collection, the amounts obtained indicate approximately the relative abundance of the plankton in the different gatherings of the series. Obviously, however, they furnish no indication of the absolute amount of material present in the water of Passamaquoddy Bay, since no data were available as to the volume of water filtered through the nets during the towing. So many factors, uncontrollble in the series of collections under consideration, enter into the question of the determination of the absolute plankton volume that it did not seem worth while to attempt an estimation of the volume of water filtered by the nets. The amounts obtained have, therefore, only a relative interest. One feature is, however, shown very clearly by the figures, namely, that with rare exceptions the collections from the 6-metre level were considerably larger than those from the surface. This may or may not have a bearing in the distribution of the plankton, since the conditions under which the collections at the two levels were made were not quite identical, the surface collections having been made with a net of finer mesh than that used at the metre level. The greater fineness of the surface net may have caused so much diminution of flow through it, that much less water was actually filtered by it than by the fathom net, in which case a less amount of plankton, even though its distribution were uniform at both levels, would be expected in the surface collection. In future series the conditions for the gatherings at the two levels will be made more uniform, and it is hoped that a definite result will be obtained as to this question of distribution. zooplankton; Passamaquoddy; distribution; Quoddy; inventory; fauna

Only three molluscs in the Passamaquoddy region of the Bay of Fundy have economic significance. The annual soft-shell clam (Mya arenaria) production now at 4 million lb will drop 2 million and fishermen's earnings will drop to $100,000 because the area of clam flats in the High Pool will decrease 95%. Annual scallop (Placopecten magellanicus) production, now at 60,000 lb, will increase to about 90,000 lb and fishermen's earnings will increase to about $36,000 because reduced water exchange in the High Pool will favour survival of larvae and recruitment of scallop stocks. The shipworm (Teredo navalis), no problem now, will become an expensive pest in the Low and High Pools because higher water temperatures will encourage the build-up of heavy breeding populations.

"Surfacing on ice of frozen-in marine bottom materials." Journal of Fisheries Research Board of Canada 31(7): 1195.
In late winter and early spring, benthic materials have been observed in patches (maximum size 400 m x 10 m) on the surface of thick fast ice. They parallel the shores of estuaries and are commonest in the southern Gulf of St. Lawrence. Materials in the patches are often in strikingly natural postures and include layers of bottom sediment and plants and animals (eelgrass, shellfish [infauna and epifauna] starfish, flounders, and sticklebacks). Apparently these are frozen to the lower surface of the ice in early winter at low tides, when ice comes in direct contact with them. When the tide rises, the ice floats and raises frozen-on materials with it. Thereafter, the floating ice is thickened by freezing of water to its lower surface, and the bottom materials are thus frozen in between two layers of ice. At the same time the ice above the frozen-in materials is thinned by ablation (sublimation and melting) at its upper surface. Eventually the benthic materials are exposed on the surface of the ice. Allied phenomena have been observed in the Bay of Fundy region. Antarctica is the only other place where this has been reported to occur regularly. These phenomena and conditions favoring their occurrence in the two areas are compared. benthic; Fundy; oceanography; estuarine; hydrography; tidesMelvin, G. D. (1976).

Arrival, length of stay, fat deposition, flight range, and migration strategy of red-necked phalaropes (P. lobatus) were studied during the 1981-1982 autumn migrations through the Quoddy region, New Brunswick, Canada. Arrivals at this staging ground reflected the sequence in departures from the Arctic breeding grounds reported in the literature. Females arrived first, followed by males and finally juveniles, based on overall population composition during the season and patterns of fat deposition. Fat was deposited at the rate of 1.0 g per day over a period of about 20 days and maximum fat reserves amounted to between 40 and 45% of fresh weight, yielding enough for potential flight ranges of 4300-5100 km. The probable wintering grounds for the Quoddy region population are the waters off Peru, with the most direct migration route from the Bay of Fundy being some 6000 km long. This distance considerably exceeds the calculated nonstop flight capacities of red-necked phalaropes, and precludes their arriving at the wintering grounds without making another feeding stop, possibly off Panama.

During the summers of 1981 and 1982, feeding ecology was studied in migrating populations of red-necked phalaropes (Phalaropus lobatus) at their late summer-early fall staging ground in the Quoddy region of the Bay of Fundy (44o 55' 45o 00'N, 66o 54' 66o 59'W). Calanus finmarchicus was both the major prey item and the most plentiful zooplankton species in the area in which the phalaropes fed (mean density, 117 individuals/m-2). The birds were consistently found in sectors of the study area corresponding to maximum C. finmarchicus concentrations, made readily available at the surface by upwelling activity. The phalaropes fed almost exclusively on this species, which made up 88.6% of the total number of prey items found in the stomachs; smaller copepods, seeds, and insects made up the rest, with a size limit for ingested prey of 6 mm. The birds fed by pecking constantly at the surface of the water while swimming in a sinusoidal pattern; this differs markedly from the spinning behavior observed near the breeding grounds. seabirds; vertebrates; fauna; feeding; Quoddy; zooplankton; invertebrates; migration; nutrition; birdsMerrill, S.

The herring fishery on the Atlantic coast is the most rapidly developing fishery in eastern Canada. Landings have tripled since 1962 and landed values have more than doubled. In 1967 the catch amounted to approximately 380,000 short tons with a value of more than $8 million. In relation to other east coast fisheries, herring ranks second only to cod in landed weight and third after cod and lobsters in landed value.About 68% (260,000 tons) of the herring catch in 1967 was landed in the Maritimes--most of it (210,000 tons) in the Bay of Fundy region. Landings in Quebec were approximately 30,000 tons and in Newfoundland 90,000 tons. The greatest percentage increase has been in the Newfoundland area where landings have increased more than ten-fold since 1962. The most spectacular increase, however, has been in the Bay of Fundy area where catches have increased by 140,000 tons since 1962.
The Biological Station of the Fisheries Research Board at St. Andrews has been very much concerned about increases in the exploitation rates for herring stocks, and is accumulating as much information as possible in order to provide the best possible evaluation of the biological impact that these are having on the various stocks. There is an urgent need by both industry and government for a reasonably accurate long term estimate of the potential of the herring harvest. With a view to providing such an estimate one of the major projects within the herring research program at St. Andrews is to study changes in the population dynamics of herring stocks especially with regard to size and age composition, recruitment, growth, catch-per-unit effort, and migrations. This report attempts to assemble in a convenient and usable form the accumulation of data from 1956 to 1967 on two of these parameters (size and age composition) for herring stocks in the Bay of Fundy region. Its purpose includes an assessment of the project for use as a guide in future work of this kind. herring; fisheries; Fundy; population; life history; vertebrates; fauna

Understanding the factors that control year-class strength and the stage of the life history at which it is determined is one of the major problems of fishery science. Because of the belief that year-class abundance of herring is determined during the larval stage a great deal of attention has been given to the study of larval herring.Recent studies of the distribution, abundance and mortality of herring larvae in relation to changes in environmental conditions include those of Graham (1936), Fish and Johnson (1937), Leim (1958), Tibbo et al (1958), Tibbo and Legare (1960), Das (1968), Graham and Davis (1971) and Sameoto (1971) all of which deal with larval herring in Northwest Atlantic.

There has been no detailed analysis of the nudibranch fauna of the northwestern Atlantic shores. Information as it now exists is a result of occasional collections in New England by workers of the past century, most notably those of Gould (1870), Verrill (1873), and, more recently, Moore ( 1950, 1964). Work on the Canadian shores consists of collections on Grand Manan Island, New Brunswick, by Stimpson (1853) but, although La Rocque ( 1953) lists a number of species for Canada, for the greater part the reports are merely northern limits of the New England collections. Thus it is the purpose of this paper to consider in greater detail the distributions and zoogeographical relationships of 14 species of nudibranchs collected intertidally along New England north of Cape Cod, Massachusetts to and including Nova Scotia. Due to the difficulties of identification of nudibranchs, systematic descriptions and comments are included. distribution; molluscs; Gulf of Maine; invertebrates; benthic; fauna; inventory; shellfish; gastropodsMiddlebrook, K., C.

The seasonal cycle of tintinnid species compositions, numerical abundance, and average lorica oral diameter was examined along a nearshore-offshore transect in the Quoddy Region of the Bay of Fundy. Among 27 species identified, Stenosemella nivalis was most abundant. Highest abundances of tintinnids were observed near the surface; hyaline forms dominated near the surface while agglutinated forms were predominant in subsurface waters. Maximum abundances of 1.8 x 108 and 9.0 x 106 cells/m2 were observed at near- and off-shore stations, respectively, in summer. Annual tintinnid productivity was estimated as 250 kJ/m2 in Passamaquoddy Bay (nearshore) and total productivity from May to October was 34 kJ/m2 in the lower Bay of Fundy (offshore). The authors conclude that tintinnid ciliates are an important trophic intermediate in the planktonic food web because of their high productivity and their ability to feed on the small highly productive phytoplankton.

Annual productivity of the copepods Acartia hudsonica and Eurytemora herdmani was estimated over a 12-mo period at three sites in Passamaquoddy Bay, New Brunswick. The sites were chosen to represent the range of habitats present in the bay. Samples were collected in vertical hauls of a 64- mu m-mesh plankton net. Total copepod productivity, assuming productivity by the rare species to be proportional to their relative numeric contribution, was estimated to be 800-850 kJ/m-2 x yr-1. Through comparison of these estimates with previously published estimates, the authors suggest that copepod productivity in coastal areas may be similar over broad geographic areas. copepods; Passamaquoddy; Quoddy; population; invertebrates; fauna; zooplankton; habitatsMiller, D.

Some 30 species of filamentous fungi were isolated from littoral marine algae by several methods. These fungi were all Fungi Imperfecti and all but five were of a terrestrial nature. The seven most frequently isolated species were tested for growth on 20 carbon compounds found in seaweeds, using the methods of Sguros, Meyers and Simms (1962). Tests were conducted in an artificial seawater medium and a mineral salts medium at both 10 and 20 C. Tests to determine the effect of seaweed leachate on growth of these fungi were also undertaken. The results indicated that the fungi were generally unable to grow on the algal polysaccharides, but showed good growth on the other algal compounds. Seaweeds were also examined for higher marine fungal parasites and/or epiphytes. Didymella fucicola was found on Fucus vesiculosus and Mycosphaerella ascophylli on Ascophyllum nodosum. fungi; seaweed; intertidal; algae; Fundy; floraMilne, W. R. and S. Corey (1986).

The distribution and relative abundance of Pleurobrachia pileus (O.F. Mueller, 1776) and Beroe cucumis (Fabricius, 1780) within the Bay of Fundy and adjacent waters were examined. Pleurobrachia pileus occurred in all surveys, maintaining a persistent centre of abundance over the southwest Nova Scotia shelf. Secondary centres of occurrence were located within the upper bay and Grand Manan-Maine regions, and were maintained by immigration from the southwest Nova Scotia region. Small P. pileus were abundant during the summer and fall, while larger animals were found in the spring. Beroe cucumis was observed to be an immigrant into the Bay of Fundy in the spring and fall and generally occurred in areas of deeper waters, with recorded abundances usually low.

The observations upon which this paper is based were made while the writer was engaged in investigations in behalf of the joint commission, named by the United States and Canada, to inquire into the fisheries of the waters contiguous to the boundary of the two countries. The studies were carried on during the summers of 1893 and 1895, and extended from Portland, Maine, to St. John, New Brunswick, with special reference to waters on and near the boundary line between Maine and New Brunswick. For the purposes of the present report it is deemed desirable to consider as a whole all of the region lying between West Quoddy Head, Maine, and Point Lepreau, New Brunswick, including Grand Manan and the St. Croix River as far as Robbinston. The region thus outlined is a natural one from both a geographical and an economic standpoint. The shore line is one of extreme irregularity, the indentation produced by the Passamaquoddy system being the dominant feature. fisheries; Gulf of Maine; Passamaquoddy; Fundy; Quoddy; herring; vertebrates; faunaMoore, L.

No abstract available. Introduction: Anadromous Atlantic salmon (Salmo salar) are native to waters of the northeastern United States, but most runs were extirpated in the latter half of the nineteenth century and the early part of the twentieth century. The principal causes for the demise were pollution and the construction of impassable dams on many rivers of New England. Continued exploitation by commercial fishing further accelerated the decline and extirpation of this species from most waters. Only populations in seven rivers of Maine have continued to exist to date, although in low numbers. Restoration efforts, conducted jointly by state and federal agencies, Indian tribes, and other parties, showed early signs of success, with increasing runs until the mid-1980's. Since that time, however, runs have declined dramatically, including those in the "downeast" rivers of eastern Maine where populations were never extirpated.The causes of the recent declines are unknown, as water quality and fish passage have improved substantially in the past decades and commercial fishing has been significantly reduced and even halted in most areas, including New England waters. The principal causes of the declines likely relate to some factors during the ocean residence by salmon, perhaps cold water temperatures (DeMont 1994) but these are difficult to identify and quantify. Freshwater sources of mortality, however, surely play a role. Salmon smolts, during their downstream migration, are delayed by dams and are subject to predation by double-crested cormorants (Krohn et al. 1995), and other aquatic birds, as well as freshwater fishes (van den Ende 1993), seals, and other predators. In addition, certain land use practices are also known to affect Atlantic salmon, especially during their freshwater reference. While recent closures and moratoriums for commercial fishing in the marine environment are attempting to address some sources of marine mortality, the influences of land use practices need to be identified. With the strong possibility that some populations of Atlantic salmon may be listed and protected under the Federal Endangered Species Act, the freshwater phase of the life cycle is of particular concern.
As a consequence, a review of the impact of land use activities on Atlantic salmon and their habitat is timely. This is especially pertinent in Maine, where 89% of the state is still forested, where the forest products industry is a major influence on the economy, where most land is privately owned, and where 99% of the Nation's runs of Atlantic salmon currently exist. Extensive information is available on the effects of land use activities on salmonids, but only a small portion of it deals with Atlantic salmon. In addition, impacts of fish and habitat have been both positive and negative, and there has been some concern, from a statistical perspective, that the response of fishes to land disturbance can not be easily categorized in short-term studies (Pella and Myren 1974). Therefore, each account in the literature must be evaluated on its own merits. Gulf of Maine; fish; salmon; vertebrates; anadromous; fauna; conservation

Fundy Tidal Power and The Environment: Proceedings of a workshop on the Environmental Implications of Fundy Tidal Power held at Wolfville, Nova Scotia, November 4-5, 1976. Wolfville, Nova Scotia, The Acadia University Institute. 187.
Shorebirds are probably the most important group of birds likely to be affected by the proposed Fundy Tidal Power project. The group includes the plovers, turnstones, sandpipers, curlews, yellowlegs, dowitchers, godwits and phalaropes, amongst others, and forms one of the most important components of the Canadian avifauna. Many of these birds occur in large numbers on east coast estuaries during their autumn migration from arctic and sub-arctic breeding grounds to wintering areas in South America. Recent work has shown that Maritimes estuaries play a critical role in the life cycles of many birds as feeding and resting areas where the birds are able to accumulate large fat reserves which serve as the energy source for the long overseas migration --and without which the journey could not be made. This paper provides a general review of recent work by the Canadian Wildlife Service (CWS) on the distribution of shorebirds in the Maritime Provinces and elsewhere in eastern North America, which has indicated that the upper Bay of Fundy is an area of major international importance for shorebirds. tidal power; shorebirds; birds; Fundy; estuarine; fauna; migration; distribution; vertebrates; feeding; mudflatsMossop, B.

From the introduction:In 1917 the writer began a study of the growth of the sea mussel (Mytilus edulis, Linn.) primarily with the object of discovering the commercial possibilities of the mussells of our Atlantic coast. The investigation was conducted chiefly on the mussels of the St. Andrew's region, New Brunswick, with the Marine Biological Station, St. Andrews as a base, but brief surveys were also made of the beds at Digby, Nova Scotia, and at Grand Manan Island, Bay of Fundy. A very limited number of shells from Hudson's Bay were also examined. The problem soon presented five main aspects, vix.; (1) the distribution of the beds and the size and number of mussels in them; (2) the age of the animals forming the beds; (3) the enemies which prey on them; (4) the factors governing their rate of growth; (5) the factors governing their distribution. mussels; molluscs; ecology; Passamaquoddy; Quoddy; Fundy; distribution; shellfish; invertebrates; fauna; benthic; bivalves

Temperature, salinity, density of zooplankton patches, and the abundance of right whales (Eubalaena glacialis glacialis) were measured concurrently during summer and autumn of 1983 and 1984 over the Grand Manan Basin, outer Bay of Fundy. Right whales appeared to exploit patches of copepods at densities greater than about 820/m3 (170 mg m-3). Patches were composed primarily of stage V Calanus finmarchicus at depths - 100 m during daylight hours. Patch densities were similar in 1983 and 1984. Potential right whale feeding areas increased in extent from late July to October, with at least two peaks of copepod biomass occurring in 1984. Right whales appear to exploit euphausiid patches in the bay only incidentally; the whales departed in 1984 when euphausiid biomass was at a maximum. The topography of the basin, prevailing summer currents, and orientation of transition zones from mixed to stratified water all combine to facilitate accumulation of copepods from the Scotian Shelf and Gulf of Maine in the central lower Bay of Fundy. This area provides an important feeding ground for this stenophagous whale species. cetacea; whales; fauna; zooplankton; invertebrates; Fundy; copepods; euphausiids; feeding; marine mammals; vertebrates; distributionNational Marine Fisheries Service (1980).

The uniqueness of the area makes Cobscook Bay well worth preserving. Perhaps the most noteworthy aspect of this complex ecosystem is the occurrence of cold water and deepwater organisms in the harbor at Eastport. It appears that environmental risks from development of Cobscook tidal power are substantial and the benefits relatively minor, but long term studies should be conducted before any final decisions on this are made. tidal power; Cobscook; Eastport; Quoddy; conservationNational Oceanic and Atmospheric Administration (1975).

A study of the major intertidal communities of the Bay of Fundy has indicated variations in vertical distribution of Mytilus edulis within the widely separated regions observed. Whereas mussel communities of considerable size occur at levels below the mean low water level (M. L. W. L.) on the Nova Scotia side of the Bay, those in the St. Andrews region (New Brunswick side) are almost entirely confined to the intertidal zone. This pronounced difference in vertical distribution has suggested the problem of determining why extensive submerged mussel communities do not grow in St. Andrews waters. Attention to this phenomenon of distribution is warranted in light of the findings of Mossop ('22) which show that the most rapid growth rate, under experimental conditions, occurs when specimens are always submerged at a depth of one foot below the water surface. mussels; intertidal; Fundy; distribution; Passamaquoddy; shellfish; invertebrates; fauna; molluscs; benthic; zonation; ecology; bivalvesNewcombe, C.

Examination of zooplankton samples from Bay of Fundy and its adjacent waters over a 9-year period revealed two common pteropod species. Limacina retroversa (Thecosomata) and Clione limacina (Gymnosomata). Two other species, Clio pyramidata (Euthecosomata) and Corolla calceola (Pseudothecosomata) were infrequently collected. Long-term horizontal distributional analyses of L. retroversa and C. limacina indicated both seasonal and annual fluctuations in abundance. Reproductive hermaphrodites of L. retroversa were present within the Bay during the spring, and probably spawned during late spring and early fall. The distribution and reproductive stages are discussed in relation to water currents, temperature and salinity parameters and trophic relationships. zooplankton; Fundy; distribution; reproduction; fauna; inventory; invertebrate; temperature; salinityNissen, S.

A distinctive rocky subtidal community (the Terebratulina community) is described from the Bay of Fundy, Canada. It is shown to consist of three closely interspersed sub-communities: a cavity sub-community, characterized by chitons, coelenterates, brachiopods, bryozoans, chordates and annelids; a rock-face sub-community, similar in composition but enriched in brachiopods and sponges; and an upper-surface sub-community, dominated by algae, chitons, bivalves and echinoids.Comparison with recently described Jurassic, Cretaceous and Recent (Mediterranean) hard-ground communities suggests a relative constancy in composition, in terms of higher taxa since the Mesozoic. Development of these (sub-)communities occurs wherever crevice or cavity systems on hard substrates lead to microenvironments differentiated mainly on the basis of water energy and light.
The composition and trophic structure of the community and the life habits of Terebratulina septentrionalis (Couthouy) are related to aspects of the environment. Marked differences in composition between the living cavity sub-community and the death assemblages in the sediments are shown to be due to differential preservation, fragmentation, population dynamics and limited local transportation. subtidal; ecology; Fundy; benthic; invertebrates; fauna; diversity; rocky

Distribution and movement patterns are described for summering (nonbreeding) black guillemots in the Deer Island region of the southwestern Bay of Fundy, Canada. Guillemots were distributed in areas with moderate current velocities (range, 30-68 cm/s) and shallow to intermediate depths (range, 17-31 m). The birds appeared to avoid shallow and deep areas with fast- or slow-moving water. Guillemots preferred islands with extensive underwater ledges, presumably because these harboured sufficient prey and provided protection from fast-moving tidal waters. Guillemots moved in and out of the approaches passively with the tide and made only small-scale flights to reposition themselves in relation to food resources. seabirds; alcids; distribution; Fundy; Deer Island; vertebrates; fauna; Quoddy; Passamaquoddy; birdsO'Brien, M. (1979). A qualitative and quantitative study of the meroplankton in Cobscook Bay, Maine, Senior thesis in Biology, Wellesley College.
Qualititative and quantitative measurements of the meroplankton in the outer and inner regions of Cobscook Bay were undertaken in two studies during the summer of 1978. Group composition and abundance of the meroplankton in the outer region were determined in this study. The double oblique towing method was used to collect forty-two samples during a six week period. Thirteen meroplankton forms were identified. These were contained in the classes: Crustacea, Pelecypoda, Gastropoda, Polychaeta, Ascidiacea, and Hydrozoa. Fish eggs and larvae were also collected. The cirripedian nauplius was the dominant larval form throughout the sampling period.Sampling was designed to give insight into the dispersal patterns of the larval forms. Statistical tests revealed no significant differences in the meroplankton sampled from the two tidal phases. Therefore, no conclusive information on the movement of the larval forms was obtained.

Gawler, et al. (1978). Seven Unusual Sub-Arctic Plants of the Maine Coast, Maine Critical Areas Program Planning Report (No. 78), Maine Critical Areas Program, Maine State Planning Office.
There are a number of plant species of northern affinities that reach their southern limit in North America along the eastern coast of Maine. In late summer of 1980, Fred Olday, hired by CAP, conducted an inventory of four of these plants along the coast of eastern Washington County. Thirty-four miles of shoreline were surveyed with the study concentrating on the eastern high cliff shoreline between Cutler and Lubec. Stations were recorded for Iris hookeri, Penny, Sedum rosea (L.) Scop., and Primula laurentiana Fern. Significant headland shrub communities dominated by Empetrum nigrum L. and stations for Mertensia maritima (L.) Gray and Sagina nodosa (L.) Fenzl. were also noted. In addition, between 1978 and 1982 various CAP staff and contractors investigated additional mainland peninsulas and islands between Cutler and Monhegan Island for the above plants and Lomatogonium rotatum (L.) Fries and Montia lamprosperma Cham.Thirty-three new stations for Iris hookeri, forty-seven for Sedum rosea, and two for Primula laurentiana are documented in this report. These include stations discovered by Olday plus additional stations reported to him and CAP by other field biologists but previously unreported in the literature. The two currently known stations for Montia lamprosperma and four for Lomatogonium rotatum are also described in this report. The distribution, habitat preferences, distinguishing features, reproduction and possible reasons for rarity of these species as well as their significance in the context of Maine's flora are described and discussed.
Twenty-two of the most exemplary sites supporting these unusual species are described in this report. These sites are ranked according to their relative significance, with priority given to sites that support the species rarest in Maine, Montia, Lomatogonium, and Primula.

Stocking density effects on growth and survival of the giant scallop, Placopecten magellanicus, held in intermediate suspension culture. 8. Annu. Meet. of the Aquaculture Association of Canada, St. Andrews, New Brunswick, (Canada).
The effect of stocking density on growth of juvenile giant scallops (Placopecten magellanicus) was assessed for one year in Passamaquoddy Bay, New Brunswick. Scallop spat were held in suspension culture (pearl nets) at 6 stocking densities ranging from 136 to 818 spat/m super(2). Scallops were sampled at 5, 8, and 12 months in order to measure growth, yield, and survival. An inverse relationship was found between growth (shell height, meat weight, and whole weight) and stocking density, with a substantial amount of growth occurring at all densities. Production and areal coverage were also inversely related to density. Overall survival was 91% and was not influenced by density. scallops; molluscs; shellfish; invertebrates; growth rate; population; fauna; Passamaquoddy; Quoddy; bivalvesParsons, G. J. and M. J.

The reproductive cycle of giant scallops (Placopecten magellanicus) was examined over a 13-yr period from 1978 to 1990 at several sites within Passamaquoddy Bay. Gonosomatic index (GSI) and gonad weight were obtained from scallops sampled approximately monthly. From 1985 to 1990, samples were collected every 2 wk during the gonad ripening and about weekly during the spawning period. Scallops in Passamaquoddy Bay had one main spawning period between July and September, with peak spawning occurring during August. Spawning was not a continuous and complete process, but was intermittent, with 2 to 3 spawning events. Spawning was highly synchronous within local populations, between sexes, and within the bay. Onset, duration, and periodicity of spawning were also similar between years. The long-term GSI pattern and maximum level in the reproductive cycle of giant scallops from Passamaquoddy Bay were annually consistent. scallops; molluscs; reproduction; Passamaquoddy; Quoddy; invertebrates; shellfish; fauna; bivalvesParsons, G.

The swimming behavior of the giant scallop, Placopecten magellanicus, was studied on about a bimonthly basis over a four year period in Passamaquoddy Bay, New Brunswick to test the hypotheses that scallops showed a seasonal pattern of swimming activity in relation to environmental variables and that the size-related swimming pattern agreed with theoretical predictions of swimming efficiency. Underwater observations and video photography, using SCUBA, were made on the swimming response of scallops when approached by a diver. Few scallops swam in the winter months, when temperature was <4 degree C. Swimming activity increased in summer and was related to temperature. Swimming rates (claps/s and velocity) were also positively correlated with temperature. Peak activity occurred in autumn and coincided with the annual temperature maxima. Peak activity was also coincident with and subsequent to spawning. Scallops from 40 to 80 mm shell height were more active compared to other sizes which agreed with theoretical predictions based on the hydrodynamics of this species. Scallop aquaculturists considering a bottom growout strategy will have to account for the impact of movement and swimming on their operation. shellfish; invertebrates; aquaculture; scallops; molluscs; fauna; Passamaquoddy; Quoddy; bivalvesParsons, G.

"Influence of environmental factors on the maximization of spat settlement in the giant scallop, Placopecten magellanicus." J. Shellfish Res.8(2): 458.
The giant scallop (Placopecten magellanicus) is a commercially important species both in Canada and the US; in an effort to develop predictors of successful recruitment, the relationship of several environmental factors (larval occurrence, substrate conditioning, and potential predators) to maxima in spat settlement was examined. The temporal distribution of larvae in Passamaquoddy Bay, N.B. revealed a pattern of 3 pulses, in which the occurrence of new veligers was correlated with tidal periodicity. The microscale influence of a biogenic film was greater than substrate texture on the intensity of spat settlement. A concordance between peak settlement times was observed, with the starfish maxima occurring about 3 weeks prior to that of scallops. The application of these results with the manipulation of spat collecting techniques will allow for an enhanced procurement of scallops for aquaculture purposes. Furthermore, with a technique now developed for aging spat, it should be possible to construct a detailed pattern of settlement and determine if a correlation exists between spawning and settlement periodicities. scallops; molluscs; fisheries; distribution; Passamaquoddy; Quoddy; aquaculture; reproduction; recruitment; invertebrates; shellfish; fauna; bivalvesParsons, J., S.

The reproductive cycle of the sea scallop, Placopecten magellanicus was examined over a 13 year period from 1978-1990 at several sites within Passamaquoddy Bay, New Brunswick, Canada. Gonad weight and gono-somatic index (GSI) were obtained from scallop samples collected on approximately a monthly basis. The annual reproductive cycle in Passamaquoddy Bay had one main spawning period from July to September with peak spawning occurring during August. Spawning lasted from 20 to 35 days. Within this period, spawning was not a continuous process, but rather was intermittent, and was manifested as 2-3 spawning events. Annual differences in GSI maxima ranged from 16.6% in 1980 to 28.5% in 1985. The maximum reproductive level for this population was 43%. Onset, duration, and periodicity of spawning were consistent between years and between sites within Passamaquoddy Bay. Juvenile scallops initiated gonad development at 40 mm (shell height) and the majority were fully mature by 60 mm. This corresponded to an age of less than one to two years. Annually, male adult scallops ripened at a faster rate and attained a higher GSI than females. Gonad ripening and spawning were synchronous between sexes. scallops; molluscs; reproduction; Passamaquoddy; Quoddy; invertebrates; fauna; shellfish; bivalvesPeacock, G. (1979).

Rep. 428, 1974, there have been a number of changes in the distribution of fish processing and handling facilities, and considerable changes in the capital investment in fish processing plants. A number of companies have undergone major expasion or modernization which matches the modernization of the fishing fleet itself. Unfortunately, the method of reporting statistics has changed somewhat and it is not, therefore, possible to give data in format exactly comparable with the 1973 figures, nevertheless, some significant trends can be shown.

Epitoniids (wentletraps) are mesogastropod prosobranchs which forage for and/or parasitize a variety of benthic coelenterates. Epitonium greenlandicum (Perry) is circumboreal in distribution and occurs subtidally in the northwestern Atlantic. Laboratory and field observations indicate that this wentletrap feeds infrequently, and only on anemones. After feeding, E. greenlandicum burrows into soft mud and can remain inactive for as long as 80 d. Wentletraps are able, at least over short distances, to locate anemones by chemotaxis. Although E. greenlandicum can feed on at least 6 species of anemone, it shows a preference for Metridium senile and tends to parasitize this large anemone under laboratory conditions. In the shallow waters of the Bay of Fundy, M. senile occurs on exposed rocks and ledges and is not available to the primarily infaunal wentletraps. Consequently, E. greenlandicum must forage for small anemones on a mixed mud-cobble bottom. It is suggested that epitoniids are able to occupy a purely ectoparasitic niche only in areas where there is both a stable supply of the host coelenterate and a nearby refuge from visual predators. molluscs; distribution; feeding; anemones; Fundy; invertebrates; fauna; benthic; ecology; habitatsPezzack, D.

Neomysis americana in Passamaquoddy Bay produces two generations per year. Breeding occurs during the spring, summer, and early fall. Each female is capable of producing two or three broods; average brood sizes for spring and summer females were 45 and 32, respectively. Development time of eggs varied directly with temperature. The intermoult period of juveniles remained constant up to the time of the development of secondary sexual characteristics, between the eighth and ninth moults, and then increased. The life history of N. americana in Passamaquoddy Bay is compared with that in other areas.

Seasonal rise in shellfish toxicity in the Bay of Fundy in 1961 was coincident with increased abundance of a marine dinoflagellate, Gonyaulax tamarensis, and the appearance of toxin in plankton extracts. Experiments with unialgal cultures of G. tamarensis isolated from the Bay of Fundy provided overwhelming evidence that it is the primary source of toxin in shellfish in this area and the Gulf of St. Lawrence. G. tamarensis is widely distributed in the North Atlantic and there is evidence of toxic and non-toxic strains of this species. paralytic shellfish poisoning; Fundy; dinoflagellates; toxins; phytoplankton; floraPrakash, A., J. C. Medcof, et al. (1971). Paralytic shellfish poisoning in eastern Canada, Fish. Res. Bd. Can. Bull. (No. 177), Fisheries Research Board of Canada.
Outbreaks of paralytic shellfish poisoning (PSP) from consumption of toxic shellfish are common in eastern Canada and have involved over 200 reported illnesses and 23 deaths since 1880. The middle and lower reaches of the Bay of Fundy and the lower estuary of the St. Lawrence River are the affected areas. Poisonings occur mainly during summer (June-September) and are associated with abundance of the planktonic marine dinoflagellate Gonyaulax tamarensis. Features of poisonings, including symptoms, levels of human sensitivity to shellfish poison, treatment, and prevention, are described.Measurements of shellfish toxicity using mouse bioassays show that toxicity varies with species of shellfish, area, and position in the intertidal zone. Shellfish species also differ in anatomical distribution of the poison. Although 14 species of shellfish have been shown to become toxic, soft-shell clams and blue mussels account for about 90% of the poisonings. Blue mussels accumulate the largest amounts of toxin in the shortest time. Possible mechanisms of toxin accumulation in molluscan shellfish, both filter feeding and nonfilter feeding, are discussed.
The causative organism, G. tamarensis, synthesizes a potent endotoxin; its toxigenic and growth characteristics and environmental factors influencing its seasonal abundance are discussed. The toxins extracted from shellfish and from G. tamarensis cultures are identical in their pharmacological characteristics and there is little doubt that they are structurally similar. Methods for measuring shellfish toxicity are described and factors affecting accuracy of mouse bioassays are reviewed.
Home cooking and commercial canning each reduce shellfish toxicity by 70-90%, and storage of toxic canned shellfish further reduces their toxicity. Toxin in live shellfish can be reduced or eliminated if they are transplanted to nontoxic areas or subjected to sudden changes in salinity and temperature.
A control program to reduce risks of poisoning without jeopardizing the shellfish fishery has been instituted. This program involves classification of shellfish-producing areas according to patterns and levels of toxin accumulation; year-round monitoring of toxicity in seriously affected areas; closures and patrolling of areas when toxin scores reach hazardous levels; and warning the public of dangers. The effectiveness of control schemes and the problems in implementing them are discussed. paralytic shellfish poisoning; Fundy; dinoflagellates; distribution; molluscs; clams; mussels; fisheries; invertebrates; shellfish; fauna; toxins; phytoplankton; flora; bivalves

Juvenile shore crabs Carcinus maenas (L.) were observed feeding on rock barnacles Semibalanus balanoides on a Bay of Fundy rocky shore. This previously unreported predatory behaviour was further investigated in the laboratory. When given a choice of three common and abundant gastropods, Nucella lapillus, Littorina littorea, and Littorina obtusata, and the rock barnacle Semibalanus balanoides, juvenile shore crabs of both sexes ate mainly barnacles and consumed proportionately more barnacles than gastropods compared with adults, which ate mainly gastropods. As the shore crab attains a certain age (size), it must forage lower on the shore as gastropods become more important in its diets. crabs; barnacles; Fundy; feeding; invertebrates; crustaceans; fauna; predation; benthic; rockyRankin, D. (1977). A qualitative and quantitative study of the zooplankton in the inner Cobscook Bay area, Senior thesis, Suffolk University.
The composition and abundance of zooplankton in the two inner bays of the Cobscook Bay complex were determined. Over a period of three weeks, twenty-eight samples were obtained by taking double oblique tows. The zooplankton in each sample was sorted and counted. Numbers of the individual groups and species per 100m3 of water filtered were calculated. Eight species and two groups of copepods, one species and five groups of holoplankton, and ten groups of meroplankton were identified. The most abundant zooplankters were three species of calanoid copepods. Three meroplanktonic forms were also occasionally found in great abundance. The nonparametric Mann Whitney U-Test, which was applied to the data, showed that there were no statistically significant differences in the composition or abundance of zooplankton between Dennys Bay and Whiting Bay.

Journal Fisheries Research Board of Canada 25(6): 1097.
The one-dimensional channel equations are integrated numerically to determine the periods and structures of the lowest three longitudinal modes of free oscillations of the Bay of Fundy. It is found that the period of the lowest mode is 9.047 hr rather than somewhere in the vicinity of the M2 tidal period of 12.42 hr, as has been supposed hitherto. This estimate of the free period is obtained without considering the effects of rotation and friction, but an approximate treatment of these effects shows that their effect on the period is very small?rotation tends to decrease the period by less than 3% and friction tends to increase it by 1% at the most. The periods of the second and third modes are found to be 5.383 and 3.475 hr. The modal structures and their modification produced by rotational effects are presented.

Scallops (Placopecten magellanicus) collected from 19 sites of commercial importance in the Maritimes were analyzed for Cu, Zn, Cd and Pb in adductor muscle, mantle, gill and viscera. Concentrations of all metals were in the order, muscle<mantle<gill<viscera, with a few exceptions. Cu and Zn levels in all scallops from the study area were comparable to those from the control site near St. Andrews. Levels of Cd and Pb in scallops from Chaleur Bay; and Cd in those from Northumberland Strait, Bay of Fundy and the offshore sites were much higher than in the controls. Scallops collected from specific sites in Chaleur Bay, known to have anthropogenic input, had still higher levels of Cd and Pb. The very high concentrations of Cd in scallops from Georges Bank and still higher in those from Browns Bank, far away from any source of anthropogenic input, suggest a natural source for the metal. metals; toxins; scallops; molluscs; Gulf of Maine; Northwest Atlantic; invertebrates; fauna; contaminants; pollution; shellfish; bivalvesRead, A.

Age at sexual maturity and pregnancy rate were estimated from a sample of 108 female harbour porpoises Phocoena phocoena killed incidentally in a commercial gill net fishery in the Bay of Fundy during July-September, 1985-88. Estimates of sexual maturity ranged from 3.15 to 3.44 yr, depending on the method used; few individuals older than 7 yr of age were present in the sample. The mean age at first pregnancy was 3.76 yr. Pregnancy rate was estimated using two methods: (1) considering the entire sample and using the presence of a corpus luteum as indicative of pregnancy, and (2) by considering the sample collected after implantation and using the presence of a foetus as the criterion of pregnancy. Estimated pregnancy rates using these two methods were 0.86 and 0.74, respectively. porpoises; reproduction; fisheries; Fundy; cetacea; marine mammals; vertebrates; faunaRead, A. J. and D. E.

Eight harbor porpoises (P. phocoena) were radio-tagged (172-173 MHz) and released in the western Bay of Fundy between August 1981 and August 1983. The duration of contact with radio-tagged animals ranged from 0.3 to 22.4 days. One harbor porpoise was tracked for 22.4 days and utilized a home range area of 210 km-2. In all observed cases, the movement of radio-tagged porpoises coincided with the direction of tidal flow in the major channels and passages of the region. Analysis of 39.2 hours of ventilation sequences revealed that radio-tagged porpoises were relatively inactive from midnight until 0600 and more active during other periods. porpoises; marine mammals; fauna; vertebrates; distribution; Fundy; cetacea; distributionRead, A.

The authors examined the nature, magnitude, and impact of incidental catches of harbor porpoises (Phocoena phocoena) by groundfish gill nets in the southwestern Bay of Fundy between June and September 1986. They estimated that the total catch for the year was 105 plus or minus 10.8 animals (SE). Nets in areas with a high density of porpoises caught more animals than those in other areas. Apparently, porpoises are entangled while nets are on the bottom in water depths of 37-96 m. No change in porpoise density was detected between 1981-86, but 2 significant changes in length frequencies (an increase in length of calves and an absence of large porpoises in the recent sample) have occurred since 1973. These changes may be attributed to the gillnet fishery. porpoises; fisheries; Fundy; cetacea; marine mammals; vertebrates; faunaRead, A. J. and D. E. Gaskin (1990). "Changes in growth and reproduction of harbour porpoises, Phocoena phocoena, from the Bay of Fundy." Canadian Journal of Fisheries and Aquatic Sciences 47: 2158.
Changes in the growth and reproduction of harbour porpoises from the Bay of Fundy are described by comparing samples collected in 1969-73 and 1985-88. The most pronounced change was an increase in the length of calves, from 92.1 cm (SE 1.6) in 1969-73 to 108 cm (SE 1.3) in 1985-88. Females in 1985-88 attained sexual maturity at a significantly younger age (3.44 yr) and shorter length (143 cm) than females from the older sample (3.97 yr and 147 cm). These changes may be attributable to an increase in prey availability to individual porpoises. porpoises; reproduction; growth rate; Fundy; cetacea; marine mammals; vertebrates; faunaReeves, R., S.

The discovery of a previously overlooked concentration of animals is one of the richest rewards of field research, especially if the creatures involved belong to an endangered species. During the last three years, while conducting airplane and boat surveys of the lower Bay of Fundy, the authors found what they believe is an important summering ground for the few surviving representatives of the North Atlantic right whale, Eubalaena glacialis, a once abundant, widely distributed species. whales; cetacea; Fundy; distribution; marine mammals; vertebrates; fauna; conservationReid, P.

The incidence of Paralytic Shellfish Poisoning along the eastern seaboard of America has increased and spread during the last decade. One of the core areas for Paralytic Shellfish Poison (PSP), a poison that is derived from toxic dinoflagellates is centred on the Bay of Fundy. It is in the upper reaches of the Bay of Fundy that a proposal has been made to construct a tidal power generation plant; this project would have a considerable effect on the water circulation, tidal regime and sedimentation characteristics of the Bay of Fundy and Gulf of Maine. Alterations such as these to the hydrography of this area may lead to changes in the occurrence of toxic dinoflagellates and the associated patterns and intensity of PSP.

Investigation of leveling-circuit misclosures indicates the presence of an uncorrected systematic error in one of the critical surveys previously used to define rapid contemporary subsidence along the coast of Maine. Reanalysis of the leveling observations after removing the suspect survey continues to indicate subsidence of easternmost Maine relative to points farther inland; however, the average rate of subsidence is reduced from 9 mm/yr, reported by Anderson et al., to about 1-2 mm/yr. This rate is similar to that derived from the Eastport, Maine, tide gauge, assuming a 1.0-1.5 mm/yr "eustatic" rise in sea level. geology; subsidence; Gulf of Maine; Cobscook; Quoddy; sea-level changeRobert, G., M.

Fisheries Research Branch.
Up to recently, the scallop fishery in southwest New Brunswick was not very important with a 20-yr mean annual landing of 8.6 t of scallop (Placopeten magellanicus) meats. A strong recruiting pulse brought drastic changes to the fishery in 1980 with well-above average landings for the area (164 t). Landings peaked at 561 t in 1981 to decline slightly in 1982 (294 t). Inshore vessels (less than or equal to 25.2 G.T.) have been responsible for the majority of landings. Even though entry into the scallop fishery is limited, there are a high number of scallop licenses, approximately 300, in the area. Scallop beds immediately surrounding Grand Manan have supported and continue to support the bulk of the fishery and with the highest catch-rates. scallops; molluscs; fisheries; economics; Quoddy; Grand Manan; invertebrates; fauna; shellfish; bivalvesRobert, G. and D.

Assessments of soft-shell clam stocks were carried out in the closed shellfish growing areas of Charlotte County, New Brunswick. Tidal flats were surveyed in Oak Bay, Passamaquoddy Bay, Digdeguash Harbour, Letang Harbour, Beaver Harbour, and Maces Bay. Stocks of clams were present in considerable numbers over the areas surveyed. It is estimated that 1,000 mt of clams in the shell could be harvested. The clam producing grounds surveyed have very heterogeneous environments and huge variations occur in clam concentrations over a short distance. clams; distribution; molluscs; Passamaquoddy; fisheries; invertebrates; shellfish; fauna; Fundy; Quoddy; bivalvesRobichaud, D.

Size and sex of trap-caught lobsters (Homarus americanus) were recorded on commercial and chartered boats from selected areas in the Bay of Fundy during 1979-88. Size-frequency distributions varied considerably between geographic areas, over fishing seasons and between years. A higher proportion of large, mature lobsters was caught in the upper reaches of the Bay of Fundy and Passamaquoddy Bay. In contrast, areas off Chance Harbour showed evidence of high recruitment and lobster landings were characterized by a large proportion of smaller lobsters close to the legal minimum size (81 mm carapace length). lobsters; fisheries; Fundy; distribution; Passamaquoddy; crustaceans; shellfish; invertebrates; Quoddy; faunaRobinson, M.

In 1989 and 1990, a survey was conducted to examine patterns of spat settlement in the sea scallop, Placopecten magellanicus, around Passamaquoddy Bay (Canada). Temperature and salinity profiles were taken at each of the spat collection sites on a monthly basis to document temperature regimes and the extent of mixing of the water column. Results indicated that settlement patterns were nonuniform and that the highest settlement densities were found in the upper part of Passamaquoddy Bay. Areas of highest settlement had densities of spat up to 3000 per bag, had the largest individuals, and were in the areas with the highest water temperatures. There was a 2-3 fold increase in the numbers of scallop spat collected in 1990 compared to 1989. Observed patterns of spat distribution corresponded very well to measured hydrographic properties and appeared to relate to the circulation of a known gyre and prevailing wind patterns at the time of settlement. scallops; molluscs; reproduction; Passamaquoddy; Quoddy; distribution; oceanography; invertebrates; hydrography; fauna; shellfish; recruitment; temperature; salinity; bivalvesRobinson, S.

The objective of this study was to test the null hypothesis: there are no consistent inter-annual spatial and temporal settlement patterns of scallop larvae (Placopecten magellanicus) in the Passamaquoddy Bay area. Spat collection bags were placed in a uniform grid pattern in Passamaquoddy Bay and surrounding areas to collect settling scallop larvae during the fall of 1989, 1990, and 1991. During the course of the study, temperature/salinity profiles were taken throughout the area, horizontal and vertical transects were performed around the Bay for chlorophyll a, and samples for scallop larvae were taken. The results refuted the null hypothesis and showed very consistent inter-annual spatial patterns of scallop spat settlement with the northern part of Passamaquoddy Bay having the highest settlement rates and mean shell heights. The spatial pattern of spat settlement closely reflected the known oceanographic properties of the area and were consistent with observations on scallop larval densities and observed chlorophyll a levels. It is postulated that the northern part of Passamaquoddy Bay may be acting as a larval nursery area for the scallop populations in the area.

No abstract available. The following is from the introduction to Chapter 13.The term microzooplankton has no precise definition; Bougis (1976) presents some useful schemes for size ranking of planktonic organisms. Without specifying size too precisely, the organisms that form the subject of this chapter fall predominantly in the range of 100m to 10mm, the spanning two orders of magnitude in size. Excluded are the phytoplankton (Chapter 11) and the macrozooplankton > 1 cm (Chapter 12). For a general introduction to marine plankton, the practical guide by Newell and Newell (1963) is excellent and Smith (1977) is also useful. The general treatments of plankton ecology by Bougis (1976) and Raymont (1963) are highly recommended, and for more description, Hardy (1956). Detalied taxonomic references may be found in these texts.
The microzooplankton of the Quoddy Region has received little attention in recent years (see Legare and MacLellan 1960 for list of older studies). The most comprehensive studies of the area are still those by Fish and Johnson (1937) and Legare and MacLellan (1960) which deal with both micro- and macrozooplankton. The extensive report of Bigelow (1926) on the nearby Gulf of Maine is also indispensable.
The Bay of Fundy microzooplankton is a rich if somewhat unpredictable mixture of neritic, oceanic, and intermediate species including arctic, boreal, and southern forms. Several of these reach their limit of distribution in the Quoddy area. Like the macrozooplankton (Chapter 12), the microzooplankton of Passamaquoddy Bay is less diverse than that of the Bay of Fundy. However, unlike the macrozooplankton, several species of microzooplankton have substantial reproduction populations in Passamaquoddy Bay, and the populations of some estuarine species are virtually limited to the bay itself.
The largest fraction of the holozooplankton (the permanent members of the animal plankton) of the oceans consists of copepods. This is generally true also in the Quoddy Region, and the Copepoda will receive the greatest attention in this chapter. However, in order to at least give honorable mention to those planktonic organisms not covered elsewhere in the volume, the other groups of the microzooplankton, both holoplanktonic and meroplanktonic (temporary members of the plankton, as larvae), will be discussed. zooplankton; Quoddy; Passamaquoddy; distribution; inventory; invertebrates; fauna; copepods

Thirty female herring (Clupea harengus) (stage VI ripe and running), collected from a fishing weir at Money Cove, Grand Manan in the Bay of Fundy, were assessed for levels of PCB and three other organochlorines (HCB, alpha-HCH, PCBz) (Musial et al., 1979). The eggs of twenty-one of these females were spawned and incubated under standardized laboratory conditions to evaluate the fertilization and viability of hatch. The age, total length, standard length, somatic, gonad and liver weights, and the calculated condition factor (somatic weight x102/(standard length)3 of these same fish were correlated with the levels of the four measured contaminants. Three replicates (each holding between 169 and 527 eggs) were run for each of the fish which was selected for the fertilization and hatching experiments. The percentage of eggs which were fertilized, the percentage of fertilized eggs which were viable at hatch (% viable hatch), the volume of the fertilized egg, the volume of the yolk sac of the hatched larvae, and the total length of the hatched larvae for each female parent were plotted with the corresponding levels of the four contaminants which were measured in the ovaries of the parents. herring; reproduction; toxins; Grand Manan; Quoddy; Fundy; contaminants; pollution; fish; vertebrates; faunaRosenthal, H. and R.

Dark Harbour (Grand Manan Island, New Brunswick, Canada) is an enclosed small bay with a narrow tidal connection to the sea. The study included bottom surveys to determine the extent of dispersal and accumulation of suspended solids, the tidal current regime, the influence of the cage system on water flow patterns, and a comparison among cage sites on the severity of benthic habitat destruction are presented. The results indicated a substantial accumulation of bottom sludge, irregular patterns of settling of suspended particles, impaired water movements due to the cage structures, and significant changes of the bottom fauna. Possible improvement, by changing cage arrangements, reducing total biomass and adapting operational conditions (changing over from wet to dry feed) are discussed. Also: Rosenthal, H. and R.W.

Two species of polychaete, Clymenella torquata and Praxillalla praetermissa, are able to maintain sufficient numerical stability to be a regular food item of fish in Passamaquoddy Bay, New Brunswick. Each species is living near an extreme of its distribution in Passamaquoddy Bay and this has necessitated adaptations in habitat and in reproductive biology.

The project began as a single summer's study of spawning and egg production by Clymenella torquata in Passamaquoddy Bay, New Brunswick. Dr. A.V. Tyler's work (1968) had indicated that this polychaete is an important food species of bay groundfish. In 1959, however, it was shown that two species of maldanid polychaetes were involved and that both were present in large numbers in the waters of the Bay. It was decided to follow the life cycles of both species and especially to determine their reproductive cycles and spawning periods.

Analysis of archaeological site locations can be used to help assess localized rates of sea-level rise provided certain conditions are met, and assumptions about the relationship between sea level and archaeological land surfaces are accurate. Provided it can be shown that marine-adapted peoples lived on contemporary shorelines, and that a particular stretch of shoreline exhibited equal potential for habitation, then differential preservation by age of site may be indicative of differential land erosion rates. This model is used to discuss the relative rates of sea-level rise for the Maine coast, divided into four shore zones.For each of the zones the archaeological evidence is reviewed together with an assessment of site loss due to sea-level rise and coastal erosion. It is concluded that the oldest coastal sites are found in the Penobscot Bay area, where 5000 year old sites are still relatively intact. The shortest record occurs in Passamaquoddy Bay where sites are no older than 2500 years. Erosion of sites, and perhaps rate of submergence, is clearly greater in Passamaquoddy Bay than elsewhere in the study area.
In addition to documentation of differential site preservation, archaeology can contribute to sea-level rise studies through the analysis of changing habitats resulting from drowned estuaries. Research on the oyster shell middens along the Damariscotta River indicates just over 1 meter of sea-level rise over the past 2500 years.
These figures may be compared with data gathered by other methods to arrive at a synthetic statement of sea-level rise and/or coastal submergence due to crustal subsidence. Gulf of Maine; geology; subsidence; sea-level change

The first successful year-round sea-cage culture of Atlantic salmon (Salmo salar) and rainbow trout (Salmo gairdneri) began in 1978 in the southwestern Bay of Fundy of New Brunswick and Maine. Production of Atlantic salmon in New Brunswick and Maine reached 3864 tonnes in 1988. Of the various constraints to expansion of salmonid mariculture in the northeast (lethal winter-sea temperature, diseases, parasites and predators, plankton blooms, early sexual maturation and chronic shortage of smolts), only lethal temperature is currently preventing rapid expansion of the industry. This increased production, together with application of suitable technology to avoid lethal temperature in other areas, now considered only marginally acceptable, are expected to result in the northeast becoming a major salmonid producer. aquaculture; salmon; trout; Fundy; fish; vertebrates; fauna; temperatureScarratt, D.

Impact of spills and clean-up technology on living natural resources, a resource-based industry, Fish. Res. Bd Can. Tech. Rept (No. 428-4), Fisheries Research Board of Canada.
The effects of oil spills are a function of the type and quantity of oil and the conditions of spillage, but in principal five responses can be identified: (1) lethal toxicity to organisms, (2) physiological or behavioural disruption, (3) mechanical interferences, (4) accumulation in organisms, (5) changes in biological habitats. Generally, the refined oils are more toxic and residual oils are more messy. Crude oils occupy an intermediate position. The nature of the principal fisheries of the Charlotte County area and the Bay of Fundy is such as to render these fisheries particularly vulnerable to oil spills, which would seem to be inevitable if a refinery and marine terminal were built at Eastport. The value of these fisheries, the investment in gear, the vulnerability of many of the fish plants, the cost and difficulty of adequate protection are such as to throw serious doubt on the wisdom of siting an oil port in the Passamaquoddy region. oil spills; Passamaquoddy; Quoddy; Cobscook; ecology; pollution; oil refinery; fisheries; Eastport; contaminants; industryScarratt, D.

Wolfville, Nova Scotia, The Acadia University Institute. 131.
When dealing with the Bay of Fundy-Gulf of Maine system relative to potential tidal power developments, it is logical to consider those resources within the areas likely to be affected by changes in the tidal regime. The obviously affected areas are those behind tidal barriers, where tidal amplitude will clearly be affected, and particularly behind impermeable barriers where there may be major changes in salinity, water level, and periodicity, particularly if the area used for pumped storage. It is likely that such areas will effectively be written off for conventional fisheries production, although there rests always the possibility that new hydrographic regimes may permit controlled production of selected, introduced species. The less obvious areas of impact are those where the tidal regime may be altered to a lesser degree and where the effects, if any, will be more subtle, less easy to predict, and possibly difficult to document after the dam is in place. The logical point of departure is Greenberg (1975) who found it necessary to extend the boundaries of his mathematical tidal model southwards to include Georges Bank and the edge of the Continental Shelf in order to get a good definition of the tide. The problem with defining the renewable resources of this region is that it encompasses administrative and political boundaries of varying types within which the methods of reporting are inconsistent and to a degree overlapping (Fig. 1). For example, the fishery statistics of both Canada and the United States deal with the volumes and values landed at specific ports or within specific administrative districts without any reference to the area where the fish were caught, while the ICNAF statistics report catches within the statistical divisions or subdivisions but in a manner which in some cases makes separation of coastal and offshore fisheries quite difficult. Thus, the selection of data has been to a degree arbitrary, and additionally biased by the ready availability of statistics.

No abstract available. The following three paragraphs are from the general introduction to the report.In the latter part of 1971, proposals were announced for the construction of a marine oil terminal and refinery at Eastport, Maine, U.S.A. The site selected, in the mouth of Cobscook Bay, is approximately 2 nautical mi from the International Boundary and about 7 mi from the open Bay of Fundy. The only access for vessels larger than local fishing craft is through the Canadian waters of Head Harbour Passage.
Canadian scientists became alarmed at the prospect of large crude and product tankers plying these waters with the attendant risk of breakdown, collision or stranding with the high probability of acute oil contamination coupled with the inevitability of chronic pollution from routine spillages and refinery discharges. The area has tidal amplitudes which exceed 8 m at spring tides and currents which may exceed 6 knots, as well as tide rips and whirlpools. Fog can be extremely common, and although the area is effectively ice free, winter conditions can give rise to strong winds, reduced visibility, and vessel icing. These conditions make navigation hazardous, and the containment and cleanup of spills impossible.
The extreme tidal currents and intense turbulence of the water give the area extremely high biological productivity upon which the economic base of the area depends. Thus, an early assessment of the marine terminal project showed policy makers that important Canadian interests would be placed at risk. These included the local marine ecology, fisheries, tourism, and recreation, and the work potential of local research institutions.

Scattergood, L. W. (1949). "Notes on the marine shark fishery." Copeia 1: 69.
Along the Maine coast, Lamna nasus commonly known as the mackerel shark by New England fishermen, appears to be second in abundance only to the spiny dogfish (Squalis acanthias). As the mackerel shark often swims in the surface waters, it is seen to a greater extent by boatmen than other common shark which dwell near the bottom. The commercial catches of mackerel sharks and dogfish seem to indicate that these two species predominate in the cold water area of the Gulf of Maine.During 1947 and 1948, I had the opportunity to examine 18 mackerel sharks landed at Portland and Eastport, Maine. Before these fish are sold, the fishermen remove the head, fins (sometimes leaving the ventrals), viscera and the tail. Through the courtesy of Captains Willard Parker, of Grand Manan Island, New Brunswick, Canada, and Carl Baade, of Portland, Maine, 6 whole sharks were brought in so that I could identify them and ascertain what conversion factors should be used to convert the dressed or drawn fish to their original lengths and weights. Although 6 sharks comprise a rather small sample, I believe that the conversion factors of 1.6 for changing dressed weights to whole or round weights and 1.7 for converting dressed lengths to whole lengths will serve until more detailed studies of sharks are necessary. fisheries; Gulf of Maine; fish; fauna; vertebrates
Scattergood, L. W. (1959). "The herring fishery of the Northwest Atlantic." Bull. Fish. Res. Bd. Can. 121: 42.
A general account is given of the history of the Northwest Atlantic fishery for herring (Clupea harengus L.) from aboriginal days to the present. The average catch during the last three decades has been 142,000 metric tons annually (313 million lb). About half of the catch is made on the Maine coast and in the Bay of Fundy; the Canadian Atlantic and the Gulf of St. Lawrence regions yield almost all of the remainder. The size of the catch seldom reflects the availability of the species in the fishing areas. Expansion of the fishery depends upon increased demand accompanied by a price that will make the fishery profitable. Offshore herring stocks, yet unfished, can be harvested, and new and better types of gear can be developed to yield greater catches. herring; fisheries; Fundy; Gulf of Maine; Northwest Atlantic; vertebrates; faunaScattergood, L.

An analysis is made of herring data collected in the Passamaquoddy Region in 1957 and 1958 to study length and age composition, year-class variation, growth, and vertebral numbers to assist in assessing the effect of proposed power dams upon the herring fishery of that Region. The scale method is rejected in favor of length-frequency analysis as a means of determining age of immature Passamaquoddy herring. Assuming derivation from fall-spawned progeny, the fishery is sustained by fish growing to a total length of between 11 and 13 cm in their first year of life, and to between 16 and 19 cm in their second year of life. Length-frequency analysis of the 1957 and 1958 data compares well with those made by other investigators in 1915 and 1932. Lack of adequate environmental data and precise aging techniques preclude determining from the 1957-1958 vertebral counts whether one or more discrete parent stocks support the fishery. herring; Passamaquoddy; Quoddy; fisheries; tidal power; growth rate; vertebrates; faunaScattergood, L.

The Government of Canada and the United States asked the International Joint Commission to determine the feasibility desirability, and cost of constructing a hydroelectric power plant in Passamaquoddy and Cobscook Bays. This electricity-producing project has two proposed impoundments, the high and low pools. Turbines in the power plant would be activated by the flow of sea water, controlled and guided through the two huge pools by a system of dams with filling or emptying gates. The International Passamaquoddy Fisheries Board was created by the International Joint Commission and was charged with the responsibility for determining the effects that this proposed tidal power project might have on the fishery economics of the United States and Canada. Accordingly, Canadian and United States scientists studied the oceanographic, biologic, and fishery economic characteristics of the "Quoddy Region" to provide a basis for assessing the economic impact of the proposed project. tidal power; herring; fisheries; Passamaquoddy; Cobscook; Quoddy; economics; vertebrates; faunaSchaeff, C. M., S. D. Kraus, et al. (1993). "Assessment of the population of western North Atlantic right whales (Eubalaena glacialis) based on sighting and mDNA data." Canadian Journal of Zoology 71: 339.
Photoidentifications and 11 years of sighting data revealed that only two-thirds of the western North Atlantic right whale (Eubalaena glacialis) reproductive females took their calves to the Bay of Fundy, the only known summer nursery. Study of cow?calf pairs further indicated that female, and to a lesser extent male, calves were philopatric with respect to this nursery. To further examine population structure, mtDNA composite restriction morphs were determined for 150 animals (47% of the population). Using 11 restriction enzymes, three composite mtDNA morphs were identified. One morph was not found among reproductive females that brought all of their calves to the Bay of Fundy. In contrast, all three morphs were present, in the same relative frequencies, among males that were seen in the Bay of Fundy and those that were not. These findings support the hypothesis that this population may be divided into two subgroups, which are defined by their use of the Fundy nursery, and that males are generally less philopatric than females. Animals from both subgroups were seen on the southern Scotian shelf, where most right whale courtship behavior was observed. Hence, although segregated by nursery areas, the western North Atlantic right whales probably represent a single breeding population.

Examinations were made of nematodes from the stomachs of 150 common porpoises (Phocoena phocoena) collected from 1952 to 1956 from the lower Bay of Fundy, one common porpoise from St. Ann's Bay, Nova Scotia, and one white whale, (Delphinapterus leucas) from Mace's Bay, New Brunswick.One adult Porrocaecum was found. Larval Porrocaecum in numbers ranging from 1 to 21 were found in about 25% of 50 porpoise stomachs collected in 1955 and 1956. Eighty larval Porrocaecum were present in the stomach of the white whale. No trace of reproductive organs was observed in any of the larval Porrocaecum.
It is concluded that the common porpoise in the lower Bay of Fundy is not an important host of adult P.decipiens.porpoises; parasites; Fundy; cetacea; vertebrates; fauna; marine mammals

Examination of monthly samples of winter flounder (P. americanus) from Passamaquoddy Bay revealed seven digenean parasites (Genolinea laticauda, Poducotyle atomon, Stenakron vetustum, Fellodistomum furcigerum, Derogenes varicus, Lecithaster gibbosus, and Steganoderma formosum) in the alimentary tract and two metacercariae (Stephanostomum baccatum and Cryptocotyle lingua) in the body surface tissues and gills. Prevalence of alimentary tract parasites ranged from 0.2 in S. formosum to 39.8 in P. atomon and intensity ranged from 1.5 for D. varicus to 7.0 for S. formosum (one fish). Monthly and seasonal levels of prevalence varied: high in spring and autumn and low in summer and winter for most species. Prevalence and length-frequency distributions of the parasites did not support differential migration by size group or diminishing feeding activity from spring to winter in winter flounder, as proposed in other studies. flounder; Passamaquoddy; Quoddy; parasites; vertebrates; fauna; fishScott, W.

No abstract available. The following is from the introduction to Chapter 10.The fishes and the fisheries of Passamaquoddy Bay and adjacent waters have been investigated extensively since the early days of this century, largely because of the existence of a highly productive commercial fishery and the early establishment (about 1899) of a biological station at St. Andrews.
The comparative richness of the Quoddy fisheries has been documented for many years. According to Huntsman (1952) the Quoddy Region had the most productive fishery for the whole of the Bay of Fundy, the Charlotte County waters yielding 147 Ib/acre (The Digby waters of Nova Scotia were next with 33 Ib/acre.) The reasons advanced for such high productivity were the combination of heavy freshwater discharge, cold salt water, and strong tides for mixing.
If the fishery itself is unique, what of the fishes that make up the fishery? How does the fauna compare with other parts of Canadian Atlantic waters or even with Canadian Pacific waters? Quoddy; fisheries; Passamaquoddy; fauna; fish; vertebrates
Seeley, R. H. (1986). "Intense natural selection caused a rapid morphological transition in a living marine snail." Proc. Natl. Acad. Sci. USA 83: 6897.
Shell shape and shell thickness of the intertidal snail Littorina obtusata changed markedly between 1871 and 1984 in northern New England. Shells collected prior to 1900 were high-spired with thin walls, whereas shells collected in 1982-84 were low-spired with thick walls. An intertidal crab (Carcinus maenas) which preys on L. obtusata expanded its range into northern New England around 1900. This suggests that the change in snail shell form was a response to predation by Carcinus. Field and laboratory experiments demonstrated that the high-spired form of L. obtusata, which can still be found in some Maine localities, is more vulnerable to predation by Carcinus than is the low-spired form of L. obtusata. Electrophoretic comparisons of high- and low-spired populations of L. obtusata confirmed that these populations represent different morphological forms of L. obtusata rather than different species [Nei's D (unbiased measure of genetic distance) = 0.003]. These data demonstrate that classical Darwinian selection can produce a rapid morphological transition without speciation. snails; crabs; distribution; predation; genetics; invertebrates; fauna; molluscs; crustaceans; benthic; gastropodsSergeant, D.

Sharp, G. J. and D. M. Tremblay (1989). An assessment of Ascophyllum nodosum resources in the Bay of Fundy, CAFSAC Research document (No. 89/1).
From current and historical databases the Ascophyllum nodosum (Rockweed) resources of Scotia Fundy were estimated to be 290,000t standing crop. The annually harvestable biomass, 47,000t, is a function of harvesting technique, harvesting strategy, and resource productivity. The majority of the harvestable biomass occurs in Southwestern Nova Scotia and Southern New Brunswick. The dramatic increase in landings from Southwestern Nova Scotia, 5000t in 1985 to 27,000t in 1988, has resulted in a wide mix of residual biomass in a variety of recovering stages in Lobster Bay, Yarmouth County, Nova Scotia. Ascophyllum requires 2 to 5 years to recover from harvesting depending on the degree of harvest and local productivity. Haphazard open harvesting of the resource will lead to a steady decline in landings beginning in l989. Fundy; seaweed; economics; algae; floraShenton, E. H. and D. B. Horton (1973). Literature review of the marine environmental data for Eastport, Maine, TRIGOM publication (No. 2A), The Research Institute of the Gulf of Maine.
A one-month review of literature and ongoing search in the region surrounding Eastport, Maine, was conducted to collect all readily available marine environmental data. A total of over 250 marine scientists were contacted by mail and telephone to determine data availability; all major marine facilities within the State were visited. Data from previous studies in the Passamaquoddy Region are assembled and reviewed in summary form for use in determining the location and installation of a marine terminal and oil refinery. Topic chapters included physical oceanography: circulation patterns, temperature, salinity, meteorology/climatology, chemical oceanography: nitrates, phosphates, silicates, geology: bedrock and surficial deposits of Eastport, biology: system ecology, marine algae, phytoplankton, zooplankton, marine invertebrates, fin fish, marine mammals, and marine birds, commercial fisheries; and water quality. Data are summarized where possible in tabular or chart form. A bibliography of major topic areas is included. Results show that although many surveys have been conducted, beginning in the 1920's through the 1957-58 Passamaquoddy Power Project, little systematic research has been done except in physical oceanography. Coverage of data for Cobscook Bay is relatively poor, leaving large gaps with no baseline data.

Study explores problems and advantages of combining tidal power production with aquacultural investments in Cobscook Bay. Principal question is whether benefits of enhanced energy and fisheries output, together with employment impact at time of construction and moderate transport and recreational gains, might reasonably exceed costs of construction and operation. Unfortunately it cannot be answered with assurance at present time. The very tentative results, based on incomplete data, are negative; costs apparently would exceed benefits. It is difficult to come up with firm cost estimates until or unless new engineering studies are undertaken. tidal power; aquaculture; Cobscook; economics; fisheries; QuoddyShowell, M. A. and D. E.

Seston samples were collected at 42 surface stations located in the Quoddy Region, New Brunswick, Canada. In an attempt to separate ecologically important components, the seston samples were divided into two size fractions: 20 to 64 mm and 0.7 to 20 mm. Particulate organic carbon, particulate aluminum, chlorophyll a, particulate cadmium, and particulate lead concentrations were determined for both size fractions. Cadmium was found to be associated almost entirely with the organic detrital component of the seston, for both size fractions. In contrast, lead was associated with several seston components. For the 20 to 64 mm size fraction, lead was partitioned between the organic detrital and suspended clay aggregate components of the seston. Within the 0.7 to 20 mm fraction, lead was partitioned, in descending order of importance, between the organic detrital, suspended clay aggregate, and phytoplankton components. toxins; Quoddy; metals; contaminants; pollutionShumway, S.

No abstract available. From the introduction:Blooms of the toxic dinoflagellate, Protogonyaulax tamarensis, are a common, seasonal occurrence in the Gulf of Maine. Shellfish (e.g., mussels, clams, oysters, scallops) can accumulate the toxins produced by P. tamarensis rendering them vectors of paralytic shellfish poisoning (PSP).
Outbreaks of PSP present a problem with respect to optimal utilization of the shellfish resource as well as public safety. Magnitude of the economic losses is large, ranging from catastrophes (e.g., New England, 1972) and an estimated loss in excess of $7,000,000 in Maine in 1980 to the recurrent costs associated with the preventative shellfish monitoring programs.
Maine has established a comprehensive sampling program that has expanded over the years to accommodate the rising value of the resource (see Figure 1; Table 1) and the expansion of the species of shellfish utilized. Maine has the largest PSP monitoring/testing program in the country with approximately 3500 samples being run annually. This number, too, increases with the increasing number of areas affected.
In this paper we describe the monitoring program from its initial efforts to determine toxicity levels of shellfish to current efforts to effectively manage a resource in the presence of a potentially lethal phenomena. In addition, data are presented on detoxification studies in Placopecten magellanicus and their implications discussed. paralytic shellfish poisoning; dinoflagellates; toxins; economics; fisheries; Gulf of Maine; phytoplankton; flora

Two relatively new approaches to the study of populations and migrations of fish--serological reactions and the use of parasites as natural tags--have provided information about mature and immature Gulf of Maine herring. Two groups of immature fish were recognizable, and spawning fish from Georges Bank were distinguishable from those spawning on the Nova Scotia coast. Immature herring from the Quoddy Region were serologically more similar to Nova Scotia than to Georges Bank spawners.

The histology, ultrastructure, and absorptive capabilities of the body wall and intestine of the juvenile stages of Nectonema sp. (Nematomorpha: Nectonematoidea) that parasitize the shrimp Pandalus montagui in Passamaquoddy Bay, New Brunswick, were examined using histological, histochemical, ultrastructural, and in vitro labeling techniques. The body wall consists of a multilayered cuticle that rests on, and is produced by, a thin cellular hypodermis. The intestinal tract consists of a minute mouth, a cuticularized oesophagus, and a blind-ending intestine consisting of a lumen surrounded at different places by two, three, or four elongated cells. These cells consist of a maximum of two "absorptive" cells with microvillar luminal surfaces, and a maximum of two "secretory" cells, which contain numerous electron-dense granules. Acid and alkaline phosphatases and nonspecific esterases were detected in the outer layers of the body wall (cuticle and hypodermis) and in the intestinal cells. shrimp; crustaceans; Quoddy; Passamaquoddy; parasites; invertebrates; faunaSmith, D.

In turn, we interpret this amount of accretion as proxy evidence of relative sea-level rise and any related vertical movements of the earth's crust. Other historic structures were also investigated as corroborative evidence, together with related historic and scientific evidence from other investigators. The amount of relative sea-level rise reported in the area from Milbridge to Eastport, Maine, has averaged about 25 to 35 centimeters per century over the last two hundred years. This result is conservatively estimated in order to minimize apparent relative sea-level changes brought about by other processes such as salt marsh compaction and disturbance of the marsh stratigraphy by the activity of severe storms.sea-level change; geology; salt marsh; Eastport; Cobscook; Quoddy; wetlandsSmith, D.

A new, detailed history of earthquakes in Maine prior to 1900 is provided. Using accounts from diaries and newspapers to supplement earlier listings, many previously uncataloged earthquakes, as well as more detailed descriptions of previously known events, have been found. Modified Mercalli intensities have been assigned to these events where possible. Historically recorded Maine earthquakes tend to be centered in the coastal zone, clustering in the Eastport and Penobscot Valley areas. They occur mostly southeast of the Norumbega fault system. seismicity; geology; Gulf of Maine; Eastport; Cobscook; QuoddySmith, G. J. D. and D. E. Gaskin (1974). "The diet of harbor porpoises (Phocoena phocoena)(L.) in the coastal waters of eastern Canada with special reference to the Bay of Fundy." Canadian Journal of Zoology 52: 777.
Stomach contents of 81 harbor porpoises (Phocoena phocoena (L.)) collected from eastern Canadian coastal waters during 1969-72 were examined. A total of 454 free otoliths and 54 undigested specimens representing a minimum of 281 fish, consisting of nine species in seven families, were recovered from the copious semi-digested fish remains in 52 of the stomachs. Clupea harengus (herring), Gadus morhua (cod), and Scomber scombrus (mackerel) otoliths accounted for more than 78% of the total. Osmerus mordax (smelt), Pollachius virens (pollock), Merluccius bilinearis (silver hake), Sebastes marinus (redfish), and Macrozoarces americanus (ocean pout) otoliths were also identified. Squid (Illex sp.), hagfish (Myxine glutinosa), and polychaetes (Nereis sp.) were identified in a few stomachs. Fifteen of the stomachs examined were empty or contained only fluid. Examination of the stomachs of the 16 smallest animals indicated that weaning occurred at body lengths of 100-104 cm. feeding; porpoises; cetacea; Fundy; fish; vertebrates; fauna; marine mammals; nutritionSmith, G.

The Bay of Fundy is a known area of concentration of Phocoena phocoena during the summer months. In this study, 698 females with calves and 5473 porpoises of other social status were sighted during 1858 hours of observation from July-September 1970-1977. It was noted that segregation of mother-calf pairs occurred in certain sectors of the study area. To evaluate habitat utilization by mother-calf pairs, a numerical index was developed. Statistical analysis revealed a significant relationship between uncorrected sightings per unit effort (S/UE) for mother-calf pairs and the habitat index. It is suggested that a complex interaction of physical and biological factors influences the distribution of mother-calf pairs. There were no strong correlations between S/UE values and individual index components, with the exception of significant correlations with increase in bottom depth and Calanus density. Females with calves appear to seek out areas of warm, stable water with high secondary productivity. Since such areas occur both inshore and offshore, the concept of a protected inshore nursery area does not seem valid for the Deer Island region. porpoises; Deer Island; Fundy; reproduction; habitats; cetacea; marine mammals; vertebrates; fauna; distribution; Quoddy; PassamaquoddySmith, G.

The Quoddy region is an ecologically unique area noted for its complex oceanographic and biological events. The interaction of large amplitude, semi-diurnal tides and the complex physiography of the region causes anomalies in the tidal current regime that affect local concentration and distribution of zooplankton. These local concentrations are important feeding sites for fish, seabirds and marine mammals. This report provides summaries of data concerning currents, water temperatures, zooplankton and schooling pelagic fish with a finer spatio-temporal resolution than any previous records for the Quoddy region. The data were collected during an extended study of upper trophic level species that are present in large numbers during the summer months, in an effort to understand the feeding and distributional ecology of such species. ecology; oceanography; hydrography; Quoddy; feeding; distribution; fish; zooplankton; food web; fauna; invertebrates; vertebrates; tides; currents; circulation; temperatureSmith, G.

In this report we examine the indirect exploitation of harbor porpoises, Phocoena phocoena, by the weir fishery for herring (Clupea harengus) in Charlotte County, New Brunswick, in the lower Bay of Fundy. This fishery is of considerable economic importance to the region; the landed value averaged 2.2 million dollars annually from 1974 to 1979 (table 11 in Iles 1979). Although herring constitute 50% of the harbor porpoise diet (Smith and Gaskin 1974), the level of competition and conflict between P. phocoena and the fishery is unknown.The harbor porpoise is taken accidentally by several commercial fisheries throughout the world (Mitchell 1975), including a pound net fishery in Denmark (Andersen l974) similar to the weir fishery of eastern Canada. In Canadian waters, harbor porpoises have been caught frequently in Newfoundland cod traps (Sergeant and Fisher 1957) and an unknown number are killed annually in gill nets in the Gulf of St. Lawrence (Laurin 1976). In addition to the indirect catch in the Bay of Fundy, harbor porpoises have been hunted for food and oil by native people and fishing families from at least the 19th century to the present (Gilpin 1878; Leighton 1937; Prescott et al. 1981). An unknown number of animals were also used as mink food in the 1950s (Fisher and Harrison 1970).
As part of a continuing study of P. phocoena, we had the opportunity to examine 48 specimens trapped in herring weirs since 1969. Eleven were tagged or equipped with radio-telemetry packs and released (Gaskin et al. 1975). The remainder were routinely autopsied and ages of 30 specimens were estimated from dentinal growth layers (Gaskin and Blair 1977). porpoises; fisheries; herring; economics; cetacea; Fundy; Northwest Atlantic; marine mammals; vertebrates; fauna

Summary:A population of the marine polyehaete Nereis virens at Brandy Cove, New Brunswick has been analyzed on the basis of weight distribution in monthly collections made throughout a year. Gametogenesis, spawning and larval life were also studied and information which adds to or differs from earlier accounts is reported. An age structure is postulated, involving a lifespan of up to 6 years. Suggestions are made as to the age at which sexual differentiation and spawning normally take place. These conclusions are compared with the results of a reinterpretation of an earlier study on a British population of the same species. worms; Fundy; reproduction; annelids; invertebrates; life history; fauna; benthic

From the introduction:Since the appearance of the first documentation of marine algae from within the political boundaries of eastern Canada (South & Cardinal, 1970), a sufficiently large volume of new information has become available to warrant the revision presented here. Taxonomic and systematic changes, together with further additions, corrections and emendations are incorporated as far as possible. A total of 346 species, subspecies and varieties are listed, comprising 131 Rhodophyta, 127 Phaeophyta and 88 Chlorophyta. The treatment is largely restricted to macroscopic forms. Inclusion of microscopic species of Chlorophyta and representatives of other marine Phyla is planned for the future.
Recent compilations are now available, with this list, of the marine algae of Iceland (Caram & Jonsson, 1972), Denmark (Christensen & Thomsen, 1974), Britain (Parke & Dixon, 1976) and Norway (Rueness, 1976). While not all Phyla are treated for the different regions, the benthic marine Rhodophyta, Phaeophyta and Chlorophyta are now documented for a considerable portion of the North Atlantic Ocean. inventory; algae; Northwest Atlantic; flora; seaweed

Twenty-three fish pen systems in Maine have been studied, and benthic conditions under these systems have been evaluated. A model has been developed to evaluate the amount of carbon accumulation and benthic deterioration under fish farms. An important feature of the model is that it deals with the dynamics of the interaction between the farm and the benthos and shows how bottom conditions change over time. There is a high degree of agreement between the predictions of the model and the field data. The model appears to provide a quantitatively useful tool to managers and regulators alike for estimating the potential benthic impacts of fish farming. aquaculture; model; Gulf of Maine; benthic; nutrientsSpeel, J.

The brachiopod, Terebratulina septentrionalis (Couthouy) is widespread in moderate depths along New England and eastern Canada. It rarely occurs intertidally in the Eastport vicinity of Passamaquoddy Bay and there only at the extreme low water mark of the lowest spring tides.

No abstract available. The following is from the introduction.The possibilities of our Canadian clam fishery, whether viewed as an industry offering employment to numbers of men, or viewed as a source of food supply to both maritime and inland people, have, undoubtedly, not yet been sufficiently appreciated. The importance of the clam for bait purposes in the catching of fish, has not in this country received the attention that has been given it or its relatives in some other countries. Its wide distribution, its abundance, and the readiness with which it may be procured on our coasts, as well as the high market value it commands in the New England States are considerations that are full of promise.
Numerous shell heaps on the coasts of New Brunswick, Nova Scotia and Prince Edward Island, sometimes more than two feet deep and occupying several acres of surface, are convincing proof that the food value of the clam was early understood by our Indians. Clams have long been handled as food and as bait in this country, in the United States and elsewhere; next to the oyster they are the most important shell-fish of the American continent; yet, until a few years ago, little of real value had been gathered respecting its habits, its mode of propagation, etc., and even at the present time there are numerous questions with regard to organization, function, food, time and manner of spawning, development, change of form and of habits in the young, rate of growth, etc., etc., which demand time, patience, trained observation, and inventive experimentation to elucidate. clams; shellfish; fisheries; molluscs; economics; ecology; Passamaquoddy; invertebrates; fauna; Quoddy; bivalves

The following is from the introduction.The second report of the Canadian Marine Biological Station (that for Canso, 1901-1902) gave a list of Porifera, Coelenterata (with the exception of the Hydroids), and Echinodermata,of St. Andrews, New Brunswick, and Canso, Nova Scotia. The present report is a continuation and embraces lists of the Hydroids, Polyzoa, Brachiopoda,and Mollusca from all five localities occupied by the station up to the present time,'viz.: St. Andrews, New Brunswick; Canso, Nova Scotia; Malpeque, Prince Edward Island; Gaspe, Presque Isle; and Seven Islands, Presque Isle.
Such lists of themselves are more or less unreadable or uninteresting, and besides give but little indication of the labour of collecting and identifying the species. Much could be said about the size, shape, colour, organs, activities, variations, reproduction, habitat, distribution, or other attributes of each. But with every change of locality of the station new forms and new features have arisen, so that the subject has been continually growing and contributing a clearer perspective of its contents as well as indicating the direction of future work. In the meantime these lists will preserve, in briefest form, much information that, through accident to specimens or notes, might otherwise be lost. Since leaving Canso it has seemed advisable to give special accounts of the faunas of the localities visited and to continue the more comparative work on phyla in a separate series.
Irrespective of the Hudson Bay regions, we may consider the study of our Atlantic fauna to have originated at three different centres.
(1) New England zoological pioneers crept up along the shores of the great Gulf of Maine to Grand Manan and reached out along the Atlantic coast of Nova Scotia for 'curios' brought back by the hazardous expeditions of Gloucester fishing fleets to Lahave, Sable Island, Banquereau, and the Grand Banks. Foremost of these were Stimpson and Verrill, whose works were afterwards supplemented by those of Nova Scotian and New Brunswick naturalists such as Willis and Ganong. (2) Naturalists from our great inland institutions wandered down the River St. Lawrence and spread over a considerable area of the gulf with Gaspe as the centre. Of these Dawson, familiarized in his youth with the rocks, weeds, and animals of the seashore at Pictou in the Acadian gulf, besides contributing most valuable papers of his own, inspired students of McGill University and the Montreal Natural History Society, his influence spreading through Bell, Whiteaves, Lambe and others to various parts of the Dominion. (3) We are again indebted to the United States naturalists Packard, Verrill, Stearns, &c., who may be regarded as having made the bleak coast of southern Labrador their centre. fauna; Northwest Atlantic; inventory; invertebrates

Pressure-sensing ultrasonic transmitters in the gut were used to determine the swimming depth of five American eels (Anguilla rostrata) in Passamaquoddy Bay, New Brunswick, in autumn. The eels made frequent dives from surface to bottom, in places diving at least 45 m deep, at vertical speeds to 76 cm/s. About one quarter of the time was spent near the surface; very little time was spent near the bottom or at any constant intermediate depth range. eels; distribution; Passamaquoddy; Quoddy; fauna; fish; vertebratesSteele, D.

No abstract available. The following is from the introduction to Chapter 5.When bedrock is exposed above the surface of the ocean it is immediately subject to erosion. The most important agents are the waves that wear away the rock and hurl loose fragments at the surface, grinding it away. Weak points in the rock structure are worked on and the more resistant sections that then lack support tumble down. The rate of erosion is therefore determined by the amount of wave energy at work on the rock and by the hardness of the rock itself.
The Quoddy Region is not normally subject to high wave energies, as the winds are not usually strong (mean velocity in the windiest month is only 20 km/h compared, for example, to 31 km/h in the Magdalen Islands). Also, the maximum fetch for most wind directions is limited. Campobello and Deer islands shield Passamaquoddy Bay from the Bay of Fundy, and the Grand Manan archipelago partially screens the eastern shore of Campobello Island. Only on the outer coasts of these islands and on the eastern shore of the mainland is the coast not sheltered. Here the maximum fetch varies from 120 to 400 km but the exposure is easterly, whereas the prevailing winds are from the west. Thus, high-energy shores with a potential for rapid erosion do not occur in the Quoddy Region.
In addition, the bedrock consists of old hard rocks that are not easily eroded. These are mainly Devonian and Silurian sedimentary and volcanic rocks, but granite occurs just to the north of the region and outcrops along the coast in the eastern portion of the region (Cumming 1967). During the Pleistocene, the Quoddy Region was traversed by glaciers and is now mantled by glacial and fluvioglacial deposits. In contrast to the bedrock, these unconsolidated deposits erode readily and supply a rich source of sedimentary material for the beaches. geology; Quoddy; sediments; bedrock; rocky
Steele, D. H. (1963). "Pollock (Pollachius virens L.) in the Bay of Fundy." Journal Fisheries Research Board of Canada 20(5): 1267.
Observations made on the biology of the pollock in the western Atlantic, and primarily in the Bay of Fundy region of the northern Gulf of Maine, are presented. The largest landings of pollock in the western Atlantic are made in this area (ICNAF Division 4X). The best catches of large fish are made at temperatures above 1.1° C, at depths of 20-100 fathoms (35-185 m) on the edges of shoals and banks where food is abundant. Spawning occurs in the winter and takes place in the southern Gulf of Maine and probably also on the Scotian Shelf, but not in the northern Gulf of Maine. The Bay of Fundy pollock are recruited from spawning in the southern Gulf of Maine and possibly on the Scotian Shelf. The pollock found in the Bay of Fundy appear to remain separate from those of the southern Gulf of Maine and the Scotian Shelf in the summer, but migrate south, spawn and probably mix with those of the southern Gulf of Maine, and possibly also those of the Scotian Shelf in the winter. The offshore pollock have a regular gradient in size across the Bay of Fundy; large fish (65-85 cm) are caught on the New Brunswick side, mediumsized fish (60-75 cm) around Grand Manan and smaller fish (45-60 cm) off western Nova Scotia. Catches with different size compositions are also found in small areas. Segregation by size into schools is therefore an important feature of pollock behaviour. The growth rate of pollock is rapid until the approximate time of sexual maturity, which occurs at ages of 4-7 years (50-65 cm) in the males and 5-7 years (55-70 cm) in the females. The growth rate of the immature and young, mature fish is similar to that recorded for other areas, but the older, mature fish appear to grow more slowly. It is suggested that this discrepancy may be due to biased sampling of the old fish in the Bay of Fundy due to the segregation by size. The 0-class pollock found in the shallow, sublittoral zone feed mainly on algae-inhabiting organisms and to a lesser extent on plankton. The 1-year-olds in the same location have a similar diet but consume a greater proportion of planktonic animals. The larger, offshore pollock in the Bay of Fundy are predominantly plankton eaters, and the euphausiid Meganyctiphanes norvegica isby far the most important organism in the diet. On the Scotian Shelf and in the Laurentian Channel fish is the dominant type of food, except for the smallest sizes of pollock.

Wolfville, Nova Scotia, The Acadia University Institute. 82.
Tidal power development within the Fundy Basin depends as much on geological and geophysical criteria as on knowledge of the tidal mechanism and engineering feasibility. Construction of a major barrier in any of several critical places within the tidal stream can only be undertaken if the bedrock floor is known to be both suitable and stable. Furthermore, interference with natural tidal rhythms will cause unfamiliar floor strains in the impounded basin due to altered loads of water and sediment, and the basin rim is likely to be subject to new erosional patterns. The placement of dams is generally cost-controlled, based chiefly on topographic criteria that aim at maximum impoundment using the smallest possible barrier. The selection of straits, narrows, and channelways for barrier construction is thus logical, but not necessarily geological, because foundation and wingwall characteristics may not always be suitable at such geometrically convenient locations.Understanding of the regional geology and tectonic evaluation of the Bay of Fundy system is a vital part of any tidal power development study. Initial planning and decisions should be guided by these perspectives, and actual construction at any particular site must be preceded by detailed and complete geological engineering studies. In view of the unusual tectonic framework of the Fundy region, careful monitoring by geodetic and geophysical means are called for before, during, and long after actual construction.
The present paper provides a broad overview of the regional geology, geophysics, and tectonic history of the Bay of Fundy region. It also considers the present tectonic-seismic regime of Nova Scotia in terms of suitability for the major engineering works of tidal power development. A more detailed analysis of potential seismic effects of barrage construction is provided by Beaumont and Quinlan (this volume, p. 262). geology; tidal power; Fundy; seismicity

Iles (1971) presented a hypothesis of larval retention in the Bay of Fundy whereby herring larvae spawned in the Trinity-Lurcher area off southwest Nova Scotia, sub-division 4Xa, were carried into the Bay of Fundy by the residual non-tidal currents on the Nova Scotia side, but were not transported out of the Bay along the New Brunswick coast by the same gyral system. It was suggested that the head of the Bay of Fundy was an overwintering area for the bulk of the larval population of the Nova Scotia stock and that post-larval movement was to the Nova Scotia rather than the New Brunswick side. This in turn implied that the Nova Scotia stock did not contribute to the New Brunswick sardines (two year old herring) fishery, a possibility that had been suggested earlier on other grounds (Iles 1970). It was also suggested that a larval concentration found to the immediate south of Grand Manan Island on the Maine-New Brunswick border, represented a separate small local stock spawning in that area.Coverage of the area was insufficient both spatially and temporally to determine larval distribution throughout the Bay of Fundy and its approaches and thus to test the hypothesis thoroughly. In particular, late or post winter sampling had not been carried out to determine post-winter distribution. In view of the large tidal fluctuations and currents in the area, dispersion throughout and transport out of the Bay of Fundy might be extensive over the winter.
A program of larval surveys in the area has been designed to give more complete spatial and temporal coverage and preliminary results of two of these are presented here.

Fifty individual right whales were identified and 34 of these were re-sighted at other locations including four from the of Georgia-Florida coast (n = 25), 20 from the Bay of Fundy (n =130), and 10 from the southern Gulf and Maine (n = 55). These results indicate the Nova Scotian continental shelf is a summer-fall right whale habitat used for social activities and feeding. whales; cetacea; Northwest Atlantic; Fundy; Gulf of Maine; distribution; migration; marine mammals; vertebrates; fauna; habitatsStone, R., E.

Experimental salmonid rearing trials (1978-79) were undertaken as a joint venture between Federal and Provincial Fisheries Departments and the private sector. Atlantic salmon, pink salmon, and rainbow trout were placed in 4- and 12-m diameter ocean pens near Deer Island, New Brunswick, and their growth was followed for 4-18 mo. Pink salmon weighing 10 g were placed in ocean pens at the beginning of June, reached a size of 248 g in 6.5 mo, and survived the winter. Under the same rearing conditions, 120-g rainbow trout reached a weight of 461 g in 4 mo. Atlantic salmon smolts, stocked in pens on May 12, 1978, at a weight of 60-80 g, were harvested 18 mo later at a weight of 3.3 kg. Small differences were observed in the growth rates of 1+ and 2+ Atlantic salmon smolts during the second summer in the sea. Pink salmon brood stock held in indoor tanks matured later in the season than expected but yielded viable products with eggs hatching normally. Two kilograms (dry weight) of a homemade moist pellet were required to produce 1 kg wet weight of Atlantic salmon or rainbow trout. Instantaneous growth rates of 450-g salmon during their first summer were double the instantaneous growth rate of 2300-g salmon during the second summer. The magnitude of salmon growth in fish pens closely resembled the growth of fish with comparable sea age on ocean feeding grounds. However, the incidence of maturation as grilse in the caged fish was less than 1% compared to 50% for hatchery returns of sea-ranched smolts of the same strain and hatchery rearing history. It is suggested that low winter temperatures and/or reduced feed intake may alter maturation rates. Despite winter sea temperatures as low as 0.9° C, it is possible to feed and overwinter Atlantic salmon with few mortalities. A marine farm, operated by two people with an annual production of between 50 and 60 tons of salmon, appears to be the minimum-sized unit necessary for economic viability. Special problem areas concerning disease, biofouling, predation, and overwintering are also considered. salmon; aquaculture; Deer Island; Quoddy; trout; fish; growth rate; feeding; vertebrates; fauna; PassamaquoddySutterlin, A.

Large concentrations of sea cucumbers (Cucumaria frondosa) are found in Passamaquoddy Bay and perhaps exist in other sheltered areas of the Maritimes. Trawl and drag methods were found suitable for their harvest in Passamaquoddy Bay. Slight modification of methods in existing fish-meal plants in the area permitted test batches of the cucumbers to be processed without difficulty. The dried cucumber meal was found to be composed of 60% crude protein, low in lipids, but containing some carotene pigments. Amino acid profiles of the meal indicate that the meal may be less suitable as dietary ingredient than herring meal. Rainbow trout fed for three months, using a moist pellet consisting of 50% substitution of cucumber meal for herring meal, exhibited low mortalities but reduced growth and reduced food intake. Pigmentation of trout flesh was yellow to orange and probably would not be appealing. echinoderms; aquaculture; Passamaquoddy; invertebrates; Quoddy; feeding; nutrition; fisheries; vertebrates; trout; faunaSwetnam, A.

No abstract available. The following is from the introduction.Diadromous fisheries management has been dominated by the ban on commercial salmon fisheries which has been in effect since 1972. This was imposed in an attempt to reduce fishing pressure on the stocks to allow them to recover from the effects of heavy fishing and habitat deterioration. Not all rivers were closed, and salmon are still allowed to be landed as a legal bycatch in other fisheries where the occasional taking of salmon is unavoidable. Commercial landings of salmon are presented in Table 1 and angling statistics in Table 2. In the angling data for New Brunswick rivers black salmon (kelts) are included in the salmon and grilse totals. Landings of other diadromous species are presented in Table 3.

Because of the unusually large tidal range in the Bay of Fundy, the intertidal zone is an extremely extensive ecosystem. This is particularly true in the upper reaches of the bay where, for instance in the Minas Basin, over one-third of the bottom is exposed at low tide. No other comparably sized marine bay in the world shares this phenomenon (Bousfield and Leim 1960). Even in the outer portions of the bay the intertidal zone is extremely extensive. The large tides coupled with local geology also account for the extreme variety of shore types within the bay. In the outer reaches of the bay where tidal range is smallest, shorelines are predominantly of rock or coarse sediment. For example, in Grand Manan Island over 95% of shores are of rock or coarse sediment and only about 2% are of mud, whereas in Charlotte County as a whole, 90% are rock and coarse sediment and 10% are mud or saltmarsh (Thomas 1973). The middle reaches of the bay although still displaying predominantly rocky shores have more muddy areas and larger saltmarshes. The upper parts of the bay principally contained in Chignecto Bay and Minas Basin have shores composed primarily of mud or sandy mud which form very extensive intertidal flats and salt marshes. In Chignecto Bay the mud flats are up to 3.5 km wide and in the Minas Basin they extend up to about 5 km from shore. These areas also show characteristically high sediment loads in the water, maintained by vigorous tidal currents. As a result of this, layers of sediment also settle on rocky intertidal areas particularly in calm weather. Even close to the mouth of the bay, sediment loads are high and light penetration consequently very limited. tides; Fundy; intertidal; sediments; habitats; oceanography; diversity; rocky; mudflats; hydrography; salt marsh; wetlandsThomas, M.

The book describes the main marine and biological systems of Passamaquoddy Bay and adjacent waters and the oceanographic and meteorological characteristics of the area. The 17 chapters, written by scientists active in this region, are grouped to cover general subject areas beginning with meteorology and oceanography. The second group covers the intertidal systems with chapters on rocky intertidal shores, rock pools, coarse sedimentary shores, and salt marshes. The third general section, containing two chapters, covers hard and sedimentary sublittoral habitats. The following four chapters discuss pelagic systems under the headings fishes, phytoplankton, larger zooplankton, and microzooplankton, respectively. Subsequently three chapters deal with the birds, amphibians and reptiles, and marine mammals. Finally coastal vegetation is described. Each chapter presents basic scientific background material, describes appropriate methods, gives particular attention to the local situation and, if appropriate, gives specific information on particularly useful or interesting localities. This wide subject treatment makes the book useful to naturalists, students, teachers, and researchers. The unique conditions fostered by the high tidal range and vigorous water exchange in the area, dominating the oceanography and moulding the biology, will be of interest to scientists throughout the world. oceanography; meteorology; Passamaquoddy; Quoddy; intertidal; subtidal; fish; plankton; birds; marine mammals; amphibians; reptiles; flora; fauna; vertebrates; hydrography; rocky; salt marsh; wetlands; habitatsThomas, M.

No abstract available. The following is the introduction to Chapter 2.The climate of the Quoddy Region is generally similar to that of the Bay of Fundy as a whole, as it results from meteorological conditions affecting much of the Maritimes and Maine. However, there are certain local effects which modify this general pattern.
There are two general air masses which govern the weather of the region: the continental air mass moving from the west and the Atlantic air mass moving in from over the ocean. These two air masses are very different in character and thus there is often a comparatively wide range in temperatures, humidities, winds, etc. from day to day and season to season. Fog occurs frequently in spring and summer and results in cooler temperatures over and near open water than inland. However, winter temperatures are milder in the bay and along the coast. The variable weather can result in large daily temperature ranges. In winter these occasionally exceed 20° C.
Spring is usually characterized by cool but changeable weather, often with a sudden transition to summer conditions. Early fall, however, is normally very settled and pleasant, with a comparatively gradual transition to winter. Snow normally starts in October or November, becomes more frequent from December to March and then declines. Frost is general from December to April, although there are brief periods with temperatures well above freezing.
As a consequence of the large tidal range and intense mixing there is negligible formation of sea ice, except in the deep bays and estuaries. Most shipboard activities are possible throughout the year. Shores ice up in intense cold but usually clear on the next tide. Shorelines and their communities such as salt marshes, headlands, etc. are usually frozen and snow-covered from January to March. In very sheltered locations, sampling from the ice is possible. meteorology; climate; Fundy; Quoddy; temperature

No abstract available. The following is the introduction to Chapter 7.Salt marshes are not well represented in the Quoddy Region, as most bays and estuaries have shores with relatively steep profiles which are not conducive to marsh formation. However, the Bay of Fundy area as a whole, as shown in Fig. 1 has extensive areas of extremely well developed and interesting salt marshes. Some are quite close to the Quoddy Region, such as the ones at Dipper Harbour and Musquash just southwest of Saint John. Within the Quoddy Region itself there are several small but well-developed salt marshes (for instance near St. George and on Campobello Island) and, in addition, most sedimentary shores have a narrow fringe of salt marsh species at about high-water mark.
Salt marshes have been extensively studied around the world, as shown by a number of comprehensive reviews of their structure and functioning (Chapman 1964, 1977; Ranwell 1972; Teal and Teal 1969). This attention has resulted partly from their wide occurrence and great ecological importance but also because they are one of the most readily studied marine systems. Being on shore and high in the intertidal zone they are inaccessible for only a few hours a day.
Good basic information and ready access are the main requirements for field teaching sites. This fact, combined with the local importance of salt marshes, dictates their inclusion in this book. Fundy; Quoddy; salt marsh; intertidal; ecology; estuarine; flora; fauna; productivity; wetlands

No abstract available. The following is from the introduction to Chapter 6.Chapter four of this book covers the rocky intertidal community and it may be considered that rock pools should have been included therein. However, detailed study has shown that tide pools are a completely separate system from that of the rocky shore. Rock pools have different physical, chemical, and biotic structures and functions which make them unique. They form a sort of intermediate situation between the coastal sea and the well-drained intertidal zone, and thus give insights into factors controlling the structure and function of these two bordering systems. For instance, they show the importance of the desiccation factor on the open shore: they are also ideal for observing pH and buffering phenomena, as well as all types of diel and annual changes in environmental parameters and environmental and biological interactions in coastal waters.....
Although there is a wealth of information on seashores, there is a paucity of information on tidal pools, particularly their functional aspects. There are no texts on pools and those on shores in general (Amos 1966; Carefoot 1977; Clayton 1974; Lewis 1964; Southward 1966; Stephenson and Stephenson 1972; Yonge 1949) provide little critical information about tidal pools. This undoubtedly results from the scarcity of scientific papers on tidal pools. This material has been most recently summarized by Ganning (1971) and includes only two studies of the Bay of Fundy region, those of Klugh (1924) and Bell (1927). Both studied a series of tide pools in front of the Biological Station St. Andrews, in an area now virtually obliterated by wharf and slip construction. Other regional studies are those of Williams and Williams (1976) on pools on the St. Lawrence northshore, Johnson and Skutch (1928) on pools in Maine, Sze (1980) on macrophytic algae at the Isles of Shoals, and Lubchenco (1978) on plant species diversity in tide pools in New England and on the Bay of Fundy.

No abstract available. The following is from the introduction to Chapter 4.Among the marine communities, those occurring on rocky intertidal shores probably receive the most attention. They are easily accessible from the land, well drained, and offer a great diversity and abundance of biota. From a teaching point of view the advantage of accessibility is augmented by the wealth of life available, which demonstrates a great variety of taxonomic, morphological, physiological, and ecologial principles and processes. They are prime collecting grounds for laboratory work on both fauna and flora.
However, despite this concentration of attention at a fairly elementary level, the ecosystem is not well understood. It seems that specific adaptations may be rather obvious but that the factors governing the structure and function of the whole system are complex and often unknown. This may partly explain the relatively low level of scientific research on rocky shores on the east coast of Canada. For the Quoddy area, despite the presence of a federal government research laboratory, an independent research laboratory, and a university, there are less than half a dozen published studies on the intertidal zone. The level of effort has expanded greatly in recent years, largely owing to the need to gather scientific information on the possible harmful effects of shoreline energy-related projects and proposals. Those of importance have been the Passamaquoddy Bay Tidal Power Proposal (Anon 1959), the Colson Cove Thermal Electric Generating Plant at Lorneville (Anon 1973a), the Eastport, Maine, Oil Refinery Proposal (Anon 1976) and the Fundy Tidal Power Proposals (Anon 1977a). Unfortunately, few of these projects have yielded published reports.
With this paucity of information, it is therefore fortunate that the intertidal zone has many universal features on a world-wide basis (Stephenson and Stephenson 1949, 1972: Lewis 1964: Southward 1966) so that studies elsewhere are applicable here. However, Bay of Fundy shores are unique in many respects. The very large tidal range results in an unusually wide and important intertidal zone. Of the total coastline of 2745 km in the bay there are 1052 km2 of intertidal zone (Thomas 1977)--a relatively huge area.
The lengths of various types of shoreline in the Canadian Quoddy Region have been tabulated by Thomas (1973) and are shown in Table 1. As the table shows, the dominant shoreline type is material ranging from broken rock to sand. Probably half of this distance consists of stable shores of large rock fragments and supports a rocky shore community. This, together with 35.2% of bedrock shores, shows that about half the shoreline is rocky intertidal. Thus there is a large area available for study. It should be emphasized that this table gives lengths of shoreline: aerial relationships would show different proportions.
This chapter includes a general description and discussion of this rocky intertidal community, appropriate study methods, and detailed descriptions of a variety of specific locations. The ecosystem described will be only that of the well-drained shore. The ecology of pools on rocky shores in markedly different and will be the subject of a separate chapter (Chapter 6).

Lacuna vincta appeared at Musquash Head, New Brunswick, in large numbers from June to August 1981 principally on lower midlittoral and infralittoral fringe Fucus edentatus. The population reached a mean maximum of 280/m2 in June; by mid-September the animals had disappeared. The L. vincta grazed heavily and deposited egg masses on Fucus edentatus but little on other species. All fine and filamentous and encrusting algal species and rock were avoided for egg deposition. Egg mass abundance peaked with the population in June with a mean of 180/m2. Mean egg production in June was 83,000/m2.Both snail and egg mass distributions were correlated with the percentage cover of F. edentatus, reaching a maximum at 40-75 cm above mean low tide level.
The snails ranged in length from 2-7 mm, consisting of three cohorts from different larval settlements. Growth was rapid in July averaging 0.6 mm/month slowing later.
The food plant Fucus edentatus showed a heavy impact of the herbivore. Weight reductions attributable to grazing rose from 56% in June to 79% in August and grazed plants tended to thicken rather than elongate with growth. Grazing removed about 79% of the net production of F. edentatus which averaged 61 g dry wt/m2/day. The impact of the L. vincta population on F. edentatus seems extraordinarily severe. molluscs; snails; growth rate; reproduction; feeding; seaweed; Fundy; invertebrates; algae; flora; fauna; population; gastropods

(1989). "Glaciomarine deltas of Maine and their relation to Late Pleistocene-Holocene crustal movements." Neotectonics in Maine. Augusta, Maine Geological Survey Bulletin 40. 43.
The deglaciation of southern Maine in late Wisconsonian time was accompanied by marine submergence of the isostatically-depressed coastal lowland. Glacial meltwater streams deposited over 100 Gilbert-type deltas into the sea during the transgressive phase of submergence, between about 14,000 and 13,000 yr B.P. These deltas were deposited either in contact with the ice margin or very close to it. They are classified into four categories based on depositional environment: ice-contact deltas (39%), esker-fed ice-contact deltas (30%), leeside deltas (26%), and distal outwash deltas (5%). Most of the deltas for which subsurface data are available accumulated in water less than 80 m deep, and the ice-contact deltas are believed to have formed along a grounded tidewater-glacier margin. Bedrock strike ridges and other hills slowed the retreat of the ice margin, causing brief standstills during which deltas were deposited adjacent to these topographic highs. The sequence of glaciomarine deltas in Maine probably formed when the transgressing sea had reached its maximum depth and relative sea level was beginning to fall in response to isostatic crustal uplift.The elevations of the contacts between the topset and foreset beds of 65 deltas in Maine and New Brunswick were measured in order to locate the positions of sea level to which the deltas were graded. These elevations were plotted and contoured to determine whether the late-glacial crustal uplift pattern has been modified appreciably by Holocene crustal movements. The elevation data for southwestern Maine indicate a minimum postglacial tilt of 2.82 ft/mi (0.53 m/km) in the central Kennebec Valley region, with higher elevations to the northwest. Deltas in eastern coastal Maine have anomalously low elevations relative to those in adjacent parts of Maine and New Brunswick. The delta elevations in the eastern region may have resulted from variations in the glacio-isostatic tilt direction across Maine and/or lowering of relative sea level by crustal uplift as the deltas were deposited. Alternatively, these elevations may define a zone of Holocene crustal subsidence with maximum relative downwarp (at least 40 ft) in the Machias-Eastport area. Contouring of delta elevations also revealed variation in the spacing of the contours between central Maine and the southern extremity of the state. This variation probably resulted from regional differences in the history of late-glacial sea-level change and/or crustal uplift in response to deglaciation. geology; Gulf of Maine; sea-level change; subsidence; glaciation

Crude laboratory experiments indicate that young herring (Clupea harengus L.) 10-15 cm long are attracted to the surface by incident light intensities which do not exceed 15-16 m-c and that the speed of attraction varies inversely with the light intensity. Sonic-sounder recordings in depths of 7-22 m show that "sardine" herring lie on or very close to the bottom on sunny, winter afternoons. At twilight they rise from the bottom in dense shoals and after dark become widely dispersed in the upper water layers. herring; fisheries; distribution; FundyTibbo, S. N. and V. M. Brawn (1960).

The Passamaquoddy investigations (Hart and McKernan, 1960) included an exploratory-fishing project designed to supplement the shore-sampling program and to locate schools or populations of herring that were not being subjected to commercial exploitation. Most of the work was done in the Passamaquoddy area of New Brunswick but there were cruises to Georges Bank and in the Kennebecasis and Long Reach areas of the Saint John River.The program included fishing experiments with bottom and pelagic trawls, with baited long-lines ("line trawls"), and with gill nets. Sonic-sounder surveys were made weekly in Passamaquoddy Bay during the summer and early autumn of 1958 and frequently but irregularly in other areas and seasons.

So seldom do capelin, Mallotus villosus (Muller), occur in the Bay of Fundy that their appearance there in substantial numbers during the winter and spring of 1965 is worthy of record. Between March 23 and May 12, 1965, more than 80,000 lb of capelin were caught in the Bay of Fundy. The catches were made in Passamaquoddy Bay and along a short stretch of coast between Deadman's Harbour and Seeley's Cove (a straight line distance of about 10 nautical miles).

Plankton surveys in the Bay of Fundy and Gulf of Maine in 1958 and 1959 indicated that the largest herring spawning areas in this region are on the northern edge of Georges Bank and off the southwest coast of Nova Scotia. The drift of larvae from the spawning grounds as indicated by increasing size and by the direction of non-tidal surface currents suggest that Bay of Fundy herring stocks are supplied chiefly from the Nova Scotia spawnings.

A major portion of the Bay of Fundy and Gulf of Maine has been surveyed for occurrence and distribution of herring larvae. Plankton samples obtained with Hardy continuous plankton recorders and plankton nets confirm major spawning areas off the southwest coast of Nova Scotia and on the northern edge of Georges Bank. Newly hatched larvae were found in abundance in these areas, but nowhere else. Drift of larvae as indicated by non-tidal surface currents suggests that Nova Scotia spawnings may contribute substantially to commercial stocks of herring in inshore areas of Maine and New Brunswick. It is possible that Georges Bank spawnings also supply herring to this region. Fundy; Gulf of Maine; herring; reproduction; distribution; fisheries; vertebrates; faunaTimson, B. S. (1976).

Thesis in Wildlife Management, University of Maine.
The status of bald eagles (Haliaeetus leucocephalus Linnaeus) breeding and wintering in Maine was evaluated to assist eventual definition of critical habitats and development of specific management guidelines.The breeding population is dispersed but locally high densities occur in coastal Maine. Most nests are near marine habitats (49%) or freshwater lakes (32%). The majority (88%) are in predominant trees, mostly (73%) eastern white pine (Pinus strobus).
Sixty-two of 99 known breeding sites were occupied in 1978. The 1977-78 productivity averaged 0.60 fledglings/occupied site. Greater production was evident at successful sites, but nesting success has not increased. Forty-nine percent of the resident pairs exhibited complete reproductive failure from 1972 to 1978. Only 36% were successful in at least 50% of their nesting attempts during this period.
Productivity was highest in eastern Maine which supports 84% of the known breeding population. Population declines in western Maine correspond to depressed production. Statewide productivity is below minimal rates estimated for population stability.
Fourteen contaminants have been detected in bald eagle eggs and carcasses from Maine. DDE, DDD, dieldrin, PCB's and mercury were in all samples. Only DDD, DDT and dieldrin residues in eggs declined during 1967-78. Contaminant levels were higher in unhatched eggs from western Maine and unsuccessful nests than from eastern Maine and successful sites. Mean eggshell thickness was 0.53 mm, 13% below the pre-1946 norm.
Midwinter surveys indicated a minimum of 116 eagles in 1977 and 109 in 1978. Age composition averaged 83% adults and 17% immatures. Low subadult proportions resulted from survey bias, low productivity of eagles breeding in Maine and possible age-dependent migration. Wintering adults were often associated with nest sites suggesting year-round residency. Wintering eagles resided primarily in marine (52%) and estuarine (31%) habitats. Sixty-seven percent were in coastal regions of eastern Maine. Midwinter populations in 4 primary wintering areas of mid- and eastern-coastal Maine averaged 43% of the state total. Undeveloped shorelines near open water were favored.
Fish, primarily bottom-dwelling species, constitute 95% of the diet at inland breeding sites. Wintering and coastal-breeding eagles occupy higher trophic levels. Birds, particularly black ducks (Anas rubripes) and gulls (Larus spp.) are utilized more as food.
Environmental contaminants found in Maine bald eagles and eggs were also detected in potential foods sampled in the state. Limited data indicate DDE residues declined in 4 food groups during 1966-76. Trends in PCB contamination are uncertain but are apparently stable or increasing. In addition, high mercury levels were found in several waterfowl species from major bald eagle wintering areas. eagles; birds; reproduction; distribution; population; Gulf of Maine; contaminants; feeding; toxins; vertebrates; fauna; ecology; pollution; habitats

The distribution, abundance, and seasonality of planktonic sea scallop larvae are important both for understanding the dynamics of the offshore fishery and for the successful development of extensive culture of sea scallops. To address questions about the distribution of sea scallop larvae, plankton sampling was carried out in a coastal area (Mahone Bay) in 1983 and the next several years. Surveys were carried out where commercial fishing is important (Georges Bank, the Bay of Fundy, and the Scotian Shelf) and in Passamaquoddy Bay. Using plankton nets and a pump system to obtain vertically stratified samples to determine vertical distribution accompanied by profiles of temperature and conductivity. Sea scallop larvae are most abundant in the waters overlying Georges Bank. Spawning there begins as early as August, but the major pulse of larval production occurs in September. In inshore areas, where sea scallop beds are smaller, shallower, and often less dense, larval production is lower and appears to be more seasonally protracted. If a thermocline is present, larvae are generally confined to the region above it. In well-mixed areas, such as in the central part of Georges Bank, sea scallop larvae are evenly distributed over the entire water column. scallops; molluscs; recruitment; Northwest Atlantic; zooplankton; invertebrates; fauna; distribution; shellfish; bivalvesTremblay, M.

Vertical distribution of sea scallop (Placopecten magellanicus) larvae was studied while anchored for 50 h at a shallow location (<25 m) off Grand Manan Island in the outer Bay of Fundy. Changes in the depth-averaged concentration of larvae (no. m super(-3)) were unrelated to changes in the centre of mass (ZCM) of larvae, and appear to reflect the movement of a patch (or patches) of larvae back and forth past the anchor station. A small-amplitude diel vertical migration, comparable to observations under controlled conditions, was indicated by changes in the ZCM. During the day the ZCM ranged from 5.2 to 11.5 m, while at night the ZCM was shallower and less variable (4.1 to 6.8 m). The concentration of all size groups was greatly reduced within 1 to 8 m of the bottom, and evidence for vertical stratification by size was lacking.

The proposed Passamaquoddy power project involves the construction of a series of dams across the mouth of Passamaquoddy and Cobscook Bays. Passamaquoddy Bay, the proposed high pool, will be filled near high water by 90 filling gates, and Cobscook Bay, the proposed low pool, will be emptied near low water by 70 emptying gates. Water will flow continuously from the high pool to the low pool, through a 30 turbine powerhouse. Tidal range will be reduced to approximately 4 ft and 8 ft in the high and low pools respectively. The effect of this proposed installation on oceanographic conditions in the region has been considered. It is concluded that currents, within the impounded bays and in the area lying inside the Bliss Island-Head Harbour region, will be altered markedly. In the Outer Quoddy Region, tidal stream directions will be altered only slightly, while the changes in speed will probably not exceed 20% of their present value. No significant change in tidal streams or residual flow is expected outside the Quoddy Region. A one per cent increase in tidal range is anticipated for the entire Bay of Fundy. Inside the impounded bays, there will be increased stratification. Seasonal variations in temperature of the surface layer will be increased. The summer maximum is expected to reach 20° C and the winter minimum will be less than 0° C. Ice cover is expected to occur over part of the impounded waters. Salinities at the surface will be reduced. Only minor changes in temperature and salinity of the deep layer are anticipated. No significant changes are expected in temperature or salinity in the Outer Quoddy Region. tidal power; Passamaquoddy; Fundy; Cobscook; oceanography; tidal; Quoddy; hydrography; temperature; salinityTrites, R.

Temperature and salinity data were collected at 14 stations for 43 cruises in the Quoddy Region during 1957 and 1958 (Fig. 1). These were designated "Qp Cruises", and were carried out as one phase of the program of the Research Committee of the International Passamaquoddy Fisheries Board in order to assist with prediction of the effects of the proposed tidal power project on the fisheries (Hart and Mckernan, 1960).In addition to the above-mentioned cruises, surveys were made in the Saint Croix and Magaguadavic estuaries in the spring and summer of 1958. Surface salinity samples were taken twice daily at the wharf of the Fisheries Research Board of Canada, Biological Station. St. Andrews, New Brunswick from December 4, 1957, until December 31, 1958. Surface temperatures have been taken there daily since 1921. Prince Sta. 5 and 6 which correspond with Sta. QP-2 and QP-8 respectively have been occupied monthly for approximately 40 years.
Many other temperature and salinity observations were made during 1957 and 1958 in conjunction with current measurements, drift bottle releases, and herring taggings. The above-mentioned data, combined with the results of observations from numerous surveys of the Quoddy Region over the past 50 years, formed the basis of a manuscript report (Forgeron, MS. 1959). The purpose of this report was to present the temporal and spatial distributions of temperature and salinity, and to infer and evaluate, where possible, the residual flow, flushing time, and controlling oceanographic factors.
In spring and summer, water temperature throughout the Quoddy Region decreases seaward with the maximum temperature of the column found at the surface. In autumn and winter the temperature in general increases seaward with the minimum temperature of the column found at the surface (Fig. 2).
The annual temperature curves in the Inner and Outer Quoddy Regions are Sinusoidal with an average surface range of 13 and 10 C° and a bottom range of 11 and 9 C° , respectively. Temperatures in the Quoddy Region generally reach a maximum in late August or early September and a minimum in late February or early March. In 1957 and 1958 the maximum and minimum monthly mean temperatures recorded for the region were 15.9 and -0.6° C, respectively.
Pyroheliometer records of insolation were collected from April 1957 through December 1958 as part of a heat budget study. A notable feature was the markedly higher solar radiation received during the recorded period of 1957 as compared with a similar period in 1958, while the corresponding water temperatures were lower. In addition the water temperatures followed air temperatures more closely than solar insolation. The dissimilarity between curves of water and air temperatures, and that of solar insolation, suggests that the air masses moving through the area are more important in producing abnormal water temperatures than is the local solar radiation.
Salinity in the Quoddy Region increases seaward throughout the year. The average ranges of surface and bottom salinities for Sta. QP-8 in the Inner Quoddy Region were 5.7 and 1.5o/oo, respectively. In the Outer Quoddy Region, at Sta. QP-2, the average annual salinity range at the surface was 1.4o/oo, and at the bottom, 0.9o/oo. Salinities in the Quoddy Region generally reach a maximum in October and a minimum in April or May. The maximum and minimum salinities recorded in the Inner Quoddy Region in 1957 and 1958 at QP stations were 32.78 and 21.91o/oo. In the Outer Quoddy Region the maximum and minimum values recorded were 33.08 and 26.52o/oo. The ranges of salinities observed in the Quoddy Region in 1957 and 1958 are probably as extreme as are likely to be found because 1957 was a relatively "dry" year and 1958 a relatively wet year in terms of fresh water discharged from the rivers.
The difference in temperature between high water and low water varied from near zero in the Outer Quoddy Region to about 0.5 C° in Passamaquoddy Bay. Average salinity differences varied from zero in the Outer Quoddy Region to about 3o/oo near the heads of estuaries. Generally between April and October there is an inverse correlation between salinity and temperature changes from high water to low water. For the remainder of the year the temperature and salinity changes occur in the same sense. Throughout the year the lowest salinity over a tidal cycle occurs near low water.
The strong tidal currents create vigorous mixing and provide rapid flushing of the region. Flushing times computed on the basis of the tidal prism and fresh water discharge were found to vary from 8 to 17 days in Passamaquoddy Bay. In the Magaguadavic. and St. Croix estuaries flushing times were 2 and 6 to 7 days respectively.
Significant differences in temperature and salinity between Western and Letite Passages were observed on a seasonal basis. If the mixing processes are similar in both passages it is concluded that residual flow is variable both in direction and magnitude from season-to-season. The wind pattern varies seasonally. It is believed that this contributes significantly in determining the non-tidal surface circulation in the Inner Quoddy Region.

The electromagnetic induction method of measuring water transports was applied to the St. Croix estuary and the Passages of the Quoddy Region in 1957 and 1958. The electrical potential differences recorded by the installations systematically followed the changing tidal streams, both diurnally and from neaps to springs. The average duration of the flooding tide into Passamaquoddy Bay was found to be approximately six hours, and for the ebbing tide, nearly six and one-half hours. The records showed that slack water in Western Passage occurred at a later time than in Letite Passage. This phase lag varied from 15 to 60 minutes with some degree of periodicity. Although difficulty and uncertainty arose in establishing the true recorder zero corresponding to slack water, it was concluded that the residual flow, while seldom very pronounced, was on the average, outward through Western Passage.

No abstract available. The following is the introduction to Chapter 3.Perhaps the single most striking oceanographic attribute of the Quoddy Region (Fig. 1) is the large tide. The visual impact from the shore is most striking, and the first impression of a town like St. Andrews may vary, depending on whether one arrives at high water or low water. In fact, if one were arriving by water aboard a ship of any great size, the arrival time would have to be timed to coincide with high water to permit docking. One can thus immediately appreciate that the tides play an important and direct role in determining man's activities in the area. The tide also plays an important but indirect role through its effect on living marine resources, and through effects on local climate and weather. Indeed, the Quoddy Region provides a small-scale demonstration of man's use of the oceans. It sustains a valuable fishery, both commercial and recreational, which creates problems of resource management. It provides port facilities and has been suggested as a site for an oil refiner and a supertanker terminal. The basins of Passamaquoddy and Cobscook bays have bene proposed for tidal power development. The St. Croix Estuary receives the effluent from the pulp mill at Woodland, as well as from the human settlements on its shores. The area attracts many tourists and has served since the early 1900s as a base for research into fisheries and oceanography. All of these present and potential uses depend on, or are influenced by, the oceanographic conditions of the region. These conditions need to be understood to permit wise management, as well as for their intrinsic interest.
From a physical oceanographic point of view, the area is diverse and interesting. The St. Croix Estuary in particular shows the competing effects of fresh water discharge and the mixing associated with strong tidal currents. There are major seasonal and inter-annual variations in the water properties. For the student, the St. Croix Estuary provides a natural laboratory for the investigation of many of the physical processes that occur throughout the world's oceans.
This chapter summarizes briefly what is known about the physical oceanography, and suggests projects which could provide some interesting insights. oceanography; tides; Quoddy; hydrography

Stomachs of young cod were opened at various time intervals after they had voluntarily eaten measured meals. More digested food left the stomach in the first few hours after the meal was given than towards the end of digestion. Instantaneous depletion rate increased rapidly with increase in acclimation temperature from 2 to 15° C. The rate was not increased at 19° C and was possibly depressed. Fish would not feed at 21° C. When meal size was varied, a straight-line relation was found between rate of gastric emptying and quantity of food in the stomach. This implies that in young cod intestinal absorption is coupled to food intake by regulation of the gastric volume. It is likely that digestion rate data could be used to estimate daily rations for fish in their own environment by measuring quantity of food in the stomach.

From trawling at least monthly on a station in Passamaquoddy Bay, New Brunswick, four groups of species were distinguished. One group of species was present on station during winter only, another group in summer only, and a third group was present throughout the year. A fourth group of species was present only occasionally. This type of temporal component structure was found in previously published data for stations with similar habitat but at different latitudes and different temperature regimes. With increased annual temperature fluctuation by locality there were proportionately more species in the periodic components and fewer in the regular component. Comparable tropical communities had very small periodic components. Passamaquoddy; fish; distribution; Quoddy; ecology; vertebrates; fauna; temperatureTyler, A. V. (1971). "Surges in winter flounder, Pseudopleuronectes americanus, into the intertidal zone." Journal of Fisheries Research Board of Canada 28(11): 1727.
Movement of winter flounders, Pseudopleuronectes americanus (Walbaum), into the intertidal zone was observed by underwater television situated in a herding fence. Flounders enter the intertidal zone with the rising tide. Peak movement occurs 2-2.5 hr after low tide. Movement generally falls off 3.5 hr after tide begins to rise. Flounders occupy the area for 6-8 hr and then surge back to the sublittoral 2.5- 0.5 hr before the next low tide. Small flounders move with the same synchrony as large flounders, but tend to make short movements up and down the beach, with net movement away from shore while tide is falling. Large flounders are more strictly directional. Movements of eight species that occurred with the flounder are compared. Because of the scale of the flounder movement, and because of published observations of pleuronectids feeding in the intertidal zone, it is proposed that the intertidal zone is a major feeding area for northern populations of winter flounder. Actions that interfere with productivity in the intertidal zone (oil pollution, tidal impoundments) are likely to reduce productivity of flounder populations. flounder; distribution; fish; feeding; intertidal; vertebrates; fauna; tidesTyler, A. V. (1972). "Food resource division among northern, marine, demersal fishes." Journal of Fisheries Research Board of Canada 29(7): 997.
The division of food resources among 13 demersal fishes was examined over a 16-month period in an area of Passamaquoddy Bay, New Brunswick. Though over 100 prey species were found in the stomachs of the predators, each predator took only three or four principal prey, and these prey made up 70-99% of the mass of the food for each predator species. Which species that a predator took as principal prey depended on prey body size, whether the prey were nekton, epi-fauna, or in-fauna; and whether or not they had a hard test or shell. Within predator species there was significant heterogeneity in diet related to size of predator individual.The seasonal predators did not feed as a group on their own set of prey species. Most principal prey species of the seasonal predators were taken simultaneously by one or two of the regulars.
Data were compared with published results from two other northern marine areas. Within Irish Sea, Sea of Okhotsk, and also Passamaquoddy winter and summer communities, only 10-24% of the possible recurrences of principal prey among predators actually occurred, i.e. there was relatively little overlap among diets. Such specialization would have adaptive significance in a food-limited production system. fish; feeding; Passamaquoddy; Quoddy; Northwest Atlantic; vertebrates; fauna; predation; ecology

Six ration levels were established among 120 large, adult winter flounder (Pseudopleuronectes americanus) by setting different feeding frequencies, but with unlimited feeding at each meal. All fish were maintained at 7° C. With decrease in feeding frequency, fish ate less food per month but more food per meal?i.e. ration compensation was attempted. At the lowest frequency, two meals per month, fish did not compensate. At any one feeding frequency, fish ate progressively more per meal from the first to the fourth (final) month of the experiment.Maintenance ration was 7.9 kcal/g per day. Weight loss on starvation was equivalent to 2.14-2.35 kcal/g per day. Gross conversion efficiency ranged from 1 to 16%, and was positively correlated with ration. Net conversion efficiency averages 24.3% and was not related to ration.
Positive correlations were found between mean calories consumed per day and condition, liver weight, percent fat in the liver, percent of fish with yolk-bearing ovaries, ovary weight, and percent of ovarian follicles with yolk. The decrease in proportion of yolked oocytes with decrease in ration was not due to increased follicular atresia, but to a decrease in number of oocytes starting vitellogenesis.
Comparisons with flounders sampled directly from Passamaquoddy Bay, New Brunswick showed that the negative correlation between condition index and percentage of oocytes not in vitellogenesis was the same for Bay and laboratory fish, the range of response being greater in the laboratory fish. The existence of this relationship was interpreted as evidence that some flounders within the Bay were not getting all the food they could use. In the face of food scarcity, the winter flounder's adaptive reproductive strategy seems to be to sacrifice egg production and maintain body weight, and so when a good year comes its body will be large and able to carry a larger ovary. fish; flounder; feeding; growth rate; reproduction; Passamaquoddy; Quoddy; vertebrates; fauna

This brochure is a digest of information about the Cobscook Tidal Power Study. It contains basic background material in a non-technical form for use at public meetings. Major topics covered: purpose of study, evaluating tidal energy (economics, timing of energy production, marketing, pooling, repayment), the need for power, delivering the power (New England power grid), profile of study area (General description with notes on geology and ecology, economic base, the people), economic aspects of tidal generation, the plan of study, and digest of 20 key issues raised at five workshops conducted in preparation for the public meetings.

(A) Contents: Section I, Introduction. Presents scope of the economic analysis, the study participants and tasks, design changes affecting the analysis, past tidal power studies, and why tidal power has been re-studied. Section II, Tidal Power Alternatives, provides sketch maps of the various alternatives considered and reflects the different dam configurations. Pertinent data in table form are presented for the alternatives with respect to installed capacity and annual energy produced, et cetera. Section III, 1979 Project Cost Estimates, describes the cost methodology, assumptions, and criteria utilized. The Cost Estimating Computer Program, which was developed for costing on the alternatives, is discussed as well as a few sample project estimates. Some general observations are made on different types of projects as a result of the study. Section IV, Relative Price Shift Analysis, discusses economic feasibility of the project using preliminary method in 1977 and the current relative price shift analysis which considers changes in underlying (real) price relationships that might occur over the life of the project. (B) Conclusions: The utilization of relative price shift analysis results in the various tidal power projects benefit-to-cost ratios being enhanced. However, tidal power, while eventually providing net benefits during several years in the high escalation rate case, does not provide net benefits over the life of the project. The reasons: high initial cost, lack of dependable capacity, and the more recent infusion of funds into alternative, less expensive forms of energy. Thus tidal power, though more competitive today, is still not justified. Cobscook; tidal power; economics; QuoddyU.S. Army Corps of Engineers (1980).

A description of water quality conditions currently existing in Cobscook Bay and those projected if the proposed tidal power project is constructed are drawn from existing literature. Sections: existing conditions (watersheds contributing to Bay: drainage area, discharge, water quality classification and listing of the little data available; Cobscook Bay: tide ranges, volumetric exchange, currents, water quality classification and data on suspended solids, temperature, salinity); future conditions (project layout, cycle of operation, water levels and flow conditions, tidal response, water quality); recommendations for future study. Construction of the tidal power project will significantly alter hydrodynamic conditions in the Bay; however, little effect is expected in the open ocean.

Results of an expanded reconnaissance study of feasibility of developing large scale tidal hydroelectric power at Cobscook Bay are presented. 4 single pool alternatives are considered: Dudley Island, Goose Island Birch Point, and Wilson Ledges. These range in size from 18 to 970 megawatts. After preliminary cost estimates, Birch Point and Goose Island were selected for further analysis. The question of financial feasibility is addressed but is unresolved. The project was found to be economically feasible using current U.S. Water Resources Council criteria. Environmental impacts would include significant alterations to the existing marine, estuarine, and riverine ecosystems. Relatively favorable long term socio-economic impacts are identified. Further steps to an operating tidal project in 1995 are outlined. Cobscook; tidal power; economics; ecology; QuoddyU.S. Army Corps of Engineers (1980).

Pittston Company proposes to process crude oil which will be delivered to the refinery on tankers up to 250,000 DWT. Principal products will be low sulfur heating and industrial fuel oils; gasoline production will be limited. In addition to EPA's review of wastewater discharge, U.S. Army Corps of Engineers must review dredging, and U.S Federal Aviation Administration must decide on releasing the City from maintaining the Municipal Airport. Environmental impacts reviewed include: air quality (refinery should have minimal impact on the area's relatively good air quality); odor (should be undetectable); noise (homes in vicinity will be severely impacted; minimal impact elsewhere) solid waste (handled on the site); water quality (discharge through a diffuser on Deep Cove pier of process water, ballast water, and sanitary wastes will meet Maine standards); socio-economic (payroll during construction will be $20 to $30 million; in operation 1200 new jobs will be created in the area with 300 employees at the refinery). Potential impacts: oil spill possibility will increase with greater amount of traffic in the area. oil refinery; oil spills; Cobscook; Eastport; economics; Quoddy; pollution; contaminants; effluentU.S. Environmental Protection Agency (1976).

From the introduction: This report summarizes biological information gathered in conjunction with an Endangered Species Act (ESA) status review for current and historic US populations of Atlantic salmon (Salmo salar). As amended in 1978, the ERA allows listing of "distinct population segments" of vertebrates as well as named species and subspecies. The Atlantic Salmon Biological Review Team, composed of staff from Region 5 of the US Fish and Wildlife Service and the Northeast Region and Science Center of the National Marine Fisheries Service (collectively the "Services") is suggesting that a distinct population segment (DPS) comprised of seven individual river populations of Atlantic salmon is "distinct" for purposes of listing under the ESA. The Team also recommends four rivers for further review, classifying Atlantic salmon in these rivers as candidtae species.

No abstract available. From the introduction:The laws that regulate the distribution of the plankton in the sea furnish a problem of paramount importance in the progressive industry of fisheries. Qualitative and quantitative determinations of the plankton are made at selected hydrographic stations, since the plankton is followed by multitudes of fishes which live on it, and those fishes are followed by others which serve as food for men.
As the plankton, which regulates, to a great extent, the migrations of the fish, is itself at the mercy of the chemical, physical and mechanical conditions of the sea, it is easily understood of what economical importance a correct knowledge of those conditions will prove. We speak of the migrations of the herrings and sardines; they are the same as those of the plankton which serve as food for them, and the presence of the plankton is ruled by depth, light, temperature, salinity, pressure and density. hydrography; oceanography; Passamaquoddy; food web; Quoddy; plankton; feeding; fish; vertebrates; invertebrates; fauna; distribution

During late summer and early autumn of both 1984 and 1985 we observed and photographed the development of a green algal bloom on intertidal mudflats in eastern Maine. The bloom culminated in the formation of thick (8-10 cm) mats and long (>50 m) serpentine rope-like structures. The algal mat was polytypic but composed primarily of Enteromorpha intestinalis L. We describe the probable sequence of events which led to the formation of algal ropes. The processes involved appear to parallel the development of ball-like masses in other algae. Algal ropes developed after mat formation, as prevailing winds and tidal currents rolled individual and entwined strands across the mudflat. The great mass of algae eventually became embedded into the sediment surface producing anoxic conditions in the substrate up to several cm deep. The ecological significance and possible negative effects of this altered environment on a commercially important bivalve species are discussed.

"Experimental evaluation of aggregation behavior in the sea urchin Strongylocentrotus droebachiensis: A reinterpretation." Mar. Biol. 90: 433.
Defensive aggregation by Strongylocentrotus droebachiensis has been invoked as the fulcrum for the transformation of macroalgal beds into coralline barrens in the northwest Atlantic. We critically examined some of the mechanisms contributing to aggregation behavior by experimentally manipulating sea urchins, purported predators and food during autumn 1983 and spring 1984 both in the laboratory and field. We utilized several approaches to examine a range of sea urchin responses to the presence of food, tethered predators, caged predators, crushed conspecifics in the field and predators in laboratory tanks. Some of the field cages had the property of allowing free passage to sea urchins while retaining lobsters; this allowed distinctions to be made between artifacts caused by cage walls or topographic barriers and unrestricted behavioral responses of sea urchins. The results falsified the hypothesis that aggregations of S. droebachiensis are elicited by predators. Except in the presence of algae, sea urchins always avoided decapod predators (but not sea stars) and fled from the vicinity of injured conspecifics. However, avoidance behavior was subordinate to feeding responses, demonstrated by mass migrations of sea urchins into cages (with lobsters) to feed on algae. We reaffirmed by observation and manipulation previous studies which showed that sea urchins aggregate only in the presence of food. Two types of sea urchin groupings were delineated: (1) surficial two dimensional associations, often caused by topographic or other features which inhibited dispersal and (2) cohesive three-dimensional aggregations induced by food. urchins; feeding; Gulf of Maine; lobsters; invertebrates; echinoderms; fauna; ecology; predation; crustaceans; shellfishVan Name, W.

The coastal volcanic belt of the northeastern United States and New Brunswick consists of a bimodal sequence of marine to subaerial Silurian and Early Devonian volcanic and associated sedimentary rocks. The Mascarene lithostratigraphic terrane of New Brunswick is probably the northern extension of this belt. This paper describes the volcanic stratigraphy, eruptive and depositional styles, paleogeography and tectonic setting of a 125 km-2 area of the mascarene terrane located along the coast of Passamaquoddy Bay. The area mapped includes a similar to 3.5 km thick bimodal and subalkaline volcanic sequence of interbedded rhyolitic and basaltic flows and pyroclastic rocks and terrigeneous shale and sandstone. The most likely setting is a volcanic plateau lacking large calderas located within a continental rift. geology; Passamaquoddy; Quoddy; bedrockVandermeulen, J. H. (1980).

Heterozygosity and growth rate have been correlated in many molluscs, although the phenomenon is not universal. Enhanced growth of heterozygous molluscs has been attributed to lower energetic requirements for basal metabolism. We have investigated heterozygote deficiency, and the correlation between single-locus and multiple-locus heterozygosity and phenotype in juveniles of the scallop Placopecten magellanicus. Six samples were collected between 22 November 1984 and 11 December 1985 at Passamaquoddy Bay, New Brunswick, Canada. On average, heterozygote deficiency was small, although somewhat higher at the octopine dehydrogenase (Odh) locus, and decreased with age. No correlation was observed between genotype and growth rate. However, we have observed in P. magellanicus a correlation between allozyme heterozygosity and octopine accumulation, a trait that relates to functional anaerobiosis, and may be related to the scallop's scope for movement. scallops; molluscs; growth rate; Passamaquoddy; Quoddy; invertebrates; fauna; genetics; shellfish; bivalvesWagner, F.

Four basic chemical and physical characteristics of Cobscook Bay were investigated: salinity, temperature, dissolved oxygen and pH. The bay was sampled at different stations, times, tides and levels in the water column. The concentrations of calcium, magnesium and DDT in the bay were also studied. The results of this study gave baseline data on temperature and salinity, combined with pH determinations. Correlations were found between the movement and turbidity of the water and the levels of the chemical constituents within that water. Advisor: not indicated.

Thesis in Geological Sciences, University of Maine, Orono, Maine.
The Lubec Embayment (LE) is a small coastal re-entrant (2.7 km2) in eastern Maine, which has undergone significant change within late Holocene time. Major geomorphic elements in the LE include two small barrier spits (Lubec and Quoddy Spits), back-barrier salt marsh (Lubec marsh), and an extensive macrotidal flat comprised predominantly of coarse grained sediments. Active wave erosion of a freshwater bog peripheral to the embayment (Carrying Place Heath) suggests the existence of an ancestral barrier prior to historical documentation. The main objectives of this study include determining major trends in historic shoreline change in the LE (that is, spit, bluff and marsh), as well as characteristics and distribution of the major sedimentary environments that have resulted from shoreline change. The principal mechanisms involved in sediment redistribution within the LE were also determined. Finally, the role of sea level rise rate and storm frequency in controlling shoreline dynamics was examined. Inspection of historic maps, charts, and air photos dating from late 1700s to present delineated major phases of shoreline change in the LE. Inferences drawn concerning paleogeography (approximately 11,500 B.P. to ca 1770) were based on interpretation of terrestrial and marine surficial geology. The development of the Lubec Marsh was reconstructed from over 50 cores (55 Eijkelkamp (or "Dutch") cores and 3 vibracores), with interpretive support from historic maps and charts. The relative importance of specific sediment transport mechanisms, such as swash bar migration and seaweed transport of gravel-sized clasts, was determined by estimating the volume of sediment transferred from intertidal sources to barrier spits. In addition, movements of seaweed colonized clasts at 16 stations across the tidal flat were checked at various intervals over a 2 month period to determine local trends in clast transport. Shoreline evolution in the LE from late Pleistocene time (approximately 11,500 B.P.) to ca 1770 involved formation and partial destruction of an ancestral gravel barrier. Disitegration of the late Pleistocene barrier (approximately 4000 B.C.) was followed by rapid erosion of Carrying Place Heath forming a large, shallow bay in which future spits would form. Historic barrier evolution can be summarized in 3 states, roughly corresponding to formation and subsequent erosion of successive barrier spits. Stage 1 (ca 1770-1805) involves continued breakup of the ancestral barrier, forming an island stranded in the intertidal zone. Spit growth from the north merged with the island, forming a second spit (ca 1830), similar in size to the present spit, though positioned farther seaward (stage 2, ca 1805 - 1850). Wave and tidal reworking of the ca 1830 spit's distal end supplied the materials necessary for growth of the modern Lubec Spit (stage 3, ca 1850 - present). Evolution of the modern Lubec Spit over the last century has allowed salt marsh to colonize the back-barrier in a fashion similar to that observed by Redfield (1972) for the Barnstable marsh in Massachusetts. Spit development within the LE has occurred rapidly through historic time, and appears to be cyclical in nature. Major processes associated with spit evolution in the LE are spit breaching, landward sediment reworking by waves and tides, and spit regeneration into forms more stable under contemporary marine conditions (that is, rate of sea level rise and sediment supply). Shoreline dynamics within the LE during the early 20th century (particularly erosion of Carrying Place Heath) appears to have been influenced by acceleration of rates of local relative sea level rise (since approximately 1930; Hicks et al., 1983). Increased rate of growth of the Lubec Spit may also be related to changing rates of sea level rise or sediment supply. The most important mechanisms of landward sediment transfer from relict intertidal sources to the Lubec Spit are migration of intertidal swash bars and seaweed transport of gravel sized clasts. The role of ice rafting in sediment redistribution has been variable through time, though is largel responsible for rapid growth of the Quoddy Spit and is important in marsh sedimentation.

Cobscook Bay tidal power: Is small really beautiful?, Senior Project, College of the Atlantic.
The harnessing of tidal power has a long history, going back to at least the 16th century. This indicates that the harnessing of tidal power probably occurred concurrently with the taming of the winds and the rivers. Back in the 1930's work was begun by the Army Corps of Engineers on a two basin tidal power project in Cobscook Bay and Passamaquoddy Bay. This work was halted in 1936 when Congressional funding was cut off. Interest in tidal power has sprung anew, as oil prices have grown. The rise in prices has brought with it a rise in electricity costs, which in turn has notified New England of its dependence on oil as an electrical generating fuel. Exploration of alternatives in energy sources has become an active field in the region.Scope of Paper: The intent of this paper is to explore the question of small scale power production in comparison with large scale centralized production. This exploration will take place along the lines of a comparison of two proposed tidal power plants in the Cobscook Bay area of Maine. Assessment of the projects will be in the light of their economic feasibility and financial viability. Advisor: Dr. Susan Mehrtens. tidal power; economics; Cobscook; Quoddy; Passamaquoddy
Watson, A. P. and D. E. Gaskin (1983). "Observations on the ventilation cycle of the harbour porpoise Phocoena phocoena (L.) in coastal waters of the Bay of Fundy." Canadian Journal of Zoology 61: 126.
The ventilation cycle of the harbour porpoise was studied through analysis of 700 dive sequences recorded in the Fish Harbour region of southern New Brunswick. Two basic ventilation patterns were recognized one (pattern A) was exhibited by travelling animals and was characterized by short submergence periods (24.4 +/- 1.6 s/SE) the second (pattern B) by animals apparently feeding and was characterized by restricted ventilation periods between which the submergence periods averaged 1.44 +/- 0.07 min. Submergences during pattern B behaviour ranged from 35 s to 4 min 4 s. One animal observed over an extended period took considerably more breaths (6.6 +/- 0.4) after dives of above-average duration than after dives of less than average duration (3.6 +/- 0.2). We found that the number of breaths per minute in each behaviour pattern were very similar (2.4 and 2.3 respectively), supporting statements by other workers that the energetic demands of diving in marine mammals may not be greater than that required for surface activity. In behavior patterns A and B respectively, harbour porpoises in this area were at the surface for only 7.2 and 7.5% of any observation period. The maximum to mean dive-time ratio in P. phocoena was noted as being almost identical to that observed in Orcinus orca. This may be a generalized relationship in all odontocetes. porpoises; cetacea; Fundy; marine mammals; vertebrates; faunaWatson, E. E. (1936). "Mixing and Residual Currents in Tidal Waters as Illustrated in the Bay of Fundy." Biological Bulletin of Canadian Zoology 2(2): 141.
The Saint John estuarial water flows out to sea as a strongly stratified layer, about 10 meters thick, retaining its lower boundary as far as Grand Manan island, a distance of 74 km. Persistence is due to the high density gradient combined with the low velocity gradient through the layer as it flows out over the deep homogeneous water. (2) The homogeneity produced in shoal water by tidal stirring excludes permanent residual currents if sufficient light water is available, the outward gravity force balancing the inward dynamic force of the peripheral current. (3) Where the waters of the bay shoal gradually the turbulent influence of bottom friction extends upward 20 to 50 meters, causing the isosteric surfaces to bend downward as they come within this distance from the bottom, but for a steep rise of the bottom the isosteres continue horizontally to meet it. (4) There are found in juxtaposition (a) stratified regions where tidal mixing causes an outflow of mixed water at an intermediate depth with an inflow both at surface and bottom, and (b) regions where a local supply of fresh water is mixed with saltier water and flows away at the surface, with a compensating inflow at bottom only. (5) Calculation shows that of the total mixing in the bay of Fundy that is effective in producing a circulation, 3% occurs in the Saint John estuary, 6% in the Quoddy passages and 14% at the head of the bay.

Oceanographic deductions as to possible changes in salinities (a minimum of 2.8 per cent as compared with present 3.1-3.2 per cent levels) temperatures and other related factors in the Passamaquoddy Project area after impoundment suggest that these changes would not be of sufficient magnitude to have any greatly adverse influence upon the abundance or quality of resident species of fish and shellfish.Anticipated reductions in erosion, scouring and turbulence together with higher water temperatures resulting from impoundment and the less rapid transportation of soluble compounds and mineral elements carried into the area and by fresh-water runoff should enhance the supply of fish and shellfish-supporting nutrients, except for those species which would be denied access by engineer structures.

In 1978, the bald eagle (Haliaeetus leucocephalus) was designated as endangered in Maine and 42 of the other contiguous states, and threatened in the remaining 5 states (USFWS 1979). Environmental contaminants adversely affected many eagle populations, and were partially responsible for this status, (Krantz et al. 1970, Wiemeyer et al. 1972). Other factors contributing to the eagle's decline included human disturbance at nest sites, habitat loss, and shooting (Palmer 1988).In addition to the conservation measures afforded by the federal designation, many states have passed laws to further protect endangered and threatened species. In 1988, Maine amended its Endangered Species Act (MRSA Title 12 Chapter 713, Subchapter V) and designated bald eagle nest sites as essential habitat, which protected these sites from many of the activities detrimental to the species.
The relationship of bald eagle productivity to environmental contamination has been a concern in Maine for many years. In 1992, Maine bald eagles occupied 140 nest sites and produced 113 eaglets, representing an average of 0.81 young/occupied nest (Figure 1). This level falls below the threshold production level of 1.00 young/occupied nest typically associated with healthy populations (Sprunt et al. 1973), a level regularly attained by other major breeding populations of eagles in the United States (USFWS 1990). It is believed that environmental contaminants may be limiting reproductive capabilities of Maine eagles to a level 15-40% below other North American populations (Owen et al. 1991). Wiemeyer et al. (1993) found that unhatched eagle eggs collected from Maine nests between 1980 and 1984 contained higher DDE, PCB, and mercury residues than elsewhere in the United States.
This report presents data from a study initiated to determine the contaminant burdens of bald eagles breeding in Maine. The study was cooperatively conducted and funded by the U.S. Fish and Wildlife Service (USFWS), Maine Department of Inland Fisheries and Wildlife (MDIFW), and the University of Maine (UM). The interpretation of these data are preliminary, and are subject to revision as additional data become available. Additional analyses conducted during this study, such as the H4IIE Rat Cell Bioassay are still unreported. Final results will be available in the thesis entitled "Contaminant Burdens and Reproductive Rates of Bald Eagles Breeding in Maine", which is currently undergoing review.

Flounders captured in summer in the intertidal zone at high tide fed mainly on food species that live in that zone. Flounders captured in the subtidal zone fed partially on food species that live there, and partially on intertidal food species. From these feeding habits, and from, the magnitude of the movement into the intertidal zone (previously reported), we conclude that large intertidal areas are major feeding grounds for winter flounder. The quantities of filamentous algae in the stomachs suggest that winter flounders can utilize plant material. flounder; fish; Fundy; feeding; intertidal; vertebrates; fauna; tidesWells, B. F. (1974).

During the past few years toxic dinoflagellate blooms have caused fish kills in the Bay of Fundy. Historically these annual blooms have had substantial impact on fisheries resources and public health in Canada because of toxin accumulation in shellfish. We are now learning that the blooms cause problems for finfish as well. Recognition of this comes during a period of intensification of the toxic blooms in the Bay of Fundy. Implications of toxic blooms for finfish extend to the St. Lawrence River Estuary, to the coastal waters of British Columbia, and to many other parts of the world.This report attempts to assess the scope of the impact of toxic blooms on Canadian finfish resources. The available information is summarized, and additional concerns and gaps in our knowledge are discussed. It is concluded that it is still too early to be able to assess the total impact of the toxic blooms on finfish resources with any degree of accuracy; but the earmarks are present to indicate that toxin-caused fish kills are recurrent events, that a variety of fishes may be affected including adult and larval stages, and consequently that these toxic blooms may well have substantial impact on finfish. The effect of toxic blooms on fish larvae is considered to be the most potentially significant aspect for finfish populations. A knowledge of these effects on larvae is sorely needed, along with a better understanding of the dynamics of toxic blooms and red tides, and of mechanisms of toxin transfer to fish. fish; toxins; dinoflagellates; Fundy; vertebrates; fauna; paralytic shellfish poisoning; phytoplankton; flora

Stomachs of C. h. harengus from a kill that occurred in the Bay of Fundy during a bloom of the toxic dinoflagellate Gonyaulax excavata contained pteropods, algal remains, and paralytic toxins. Experiments show that comparable amounts of G. excavata toxins can kill herring rapidly. It is likely that the kill was caused by paralytic dinoflagellate toxins, and that the pteropod Limacina retroversa, a planktonic herbivore, acted as a vector of the toxins. herring; toxins; dinoflagellates; phytoplankton; feeding; invertebrates; paralytic shellfish poisoning; fish; vertebrates; fauna; Fundy; floraWhite, A. W. (1980). "Recurrence of kills of Atlantic herring (Clupea harengus harengus) caused by dinoflagellate toxins transferred through herbivorous zooplankton." Canadian Journal of Fisheries and Aquatic Sciences 37(12): 2262.
Kills of adult herring occurred in two localities in the southwestern Bay of Fundy in July 1979 during a bloom of the toxic dinoflagellate Gonyaulax excavata. Fish showed the same symptoms as in a herring kill linked to G. excavata toxins in 1976. Herring stomachs contained G. excavara toxins (66-245 g/100 g guts), the cladoceran Evadne nordmanni, and yellow-brown material probably of algal origin. At the time of the kills the zooplankton community was overwhelmingly dominated by E. nordmanni. Furthermore, bioassays showed the presence of G. excavata toxins in the zooplankters (18 g/g wet plankton). Combined with evidence from the 1976 kill in which pteropods were vectors of the toxins, and with results from recent field and laboratory studies, these new observations and results substantiate that (1) G. excavata toxins can, and do, cause herring kills in nature with planktonic herbivores, E. nordmanni in this case, acting as vectors, and (2) the toxin transfer mechanism is a general phenomenon among herbivorous zooplankton. Similar food chain events may affect finfish in other areas of the world which experience blooms of toxic dinoflagellates.

Marine fishes (Atlantic herring, American pollock, winter flounder, Atlantic salmon, and cod) were dosed orally and intraperitoneally (i.p.) with "paralytic shellfish toxins" extracted from Bay of Fundy Gonyaulax excavata (tamarensis) cells. The toxins are lethal to these fishes in low oral doses, and in extremely low i.p. doses. Symptoms are the same among these fishes, both for oral and i.p. administrations, including loss of equilibrium within 5 to 15 min, followed by immobilization and shallow, arrhythmic breathing. Death generally occurs within 20 to 60 min of toxin administration. Dose responses are also similar among these fishes. Oral LD50 values are 400 to 750 mug saxitoxin (STX) equivalent kg-1 body weight. Intraperitoneal LD50 values are 4 to 12 mug STX equivalent kg-1. Toxins are undetectable in fish muscle tissue following lethal oral doses. The similarity of symptoms and dose responses suggest that fish as a group are sensitive to G. excavata toxins. Results, in combination with reports implicating these toxins in herring, sand lance, and menhaden kills, show the plausibility that the nearly worldwide blooms and red tides of G. excavata and its relatives may cause kills of a variety of fishes. fish; dinoflagellates; toxins; Fundy; vertebrates; paralytic shellfish poisoning; fauna; phytoplankton; flora; red tideWhite, A.

Shellfish toxicity records for the Bay of Fundy show that during the past 8 years or so toxic Gonyaulax blooms and shellfish toxicity have been more intense than at any time in the preceeding 30 year period. In addition to dangerously high shellfish toxicity levels during the summer, there has been a recent trend of persistence of toxicity throughout the rest of the year, probably caused by prolonged depuration of high summer toxin loads and by recombination of shellfish upon ingestion of overwintering Gonyaulax cysts. Recent year-round closures of major shellfish areas are unprecedented in the 39 year history of the shellfish toxicity monitoring program. Possible courses of action which may help the shellfish industry cope if present trends continue include development of detoxification methods, production of canned shellfish, and exploration of the possibility of slightly relaxing the present shellfish toxicity limit during non-bloom periods. toxins; Fundy; dinoflagellates; paralytic shellfish poisoning; phytoplankton; floraWhite, A.

During the winter of 1980-1981 sediment samples were collected from 115 stations throughout the southern Bay of Fundy to determine the distribution and abundance of G. excavata resting cysts. An improved, semiquantitative method of cyst enumeration was developed for this purpose. Resting cysts of G. excavata were widely dispersed in the Bay, occurring both offshore and inshore, including the intertidal zone. The great majority of cysts occurred in a large, extremely rich deposit located offshore in the southwestern Bay of Fundy in a zone of fine brown mud at depths of 80-160 m. The location of this deposit was consistent with hydrographic and sedimentary processes in the Bay. Cyst concentrations ranged from 2000 to 8000 cysts/cm-3 wet sediment at many stations in the approximately 2000-km-2 deposit. Cyst toxicity is examined. The offshore seed bed serves as the primary source of the motile cells which initiate the annual G. excavata bloom in the Bay of Fundy. dinoflagellates; toxins; distribution; Fundy; paralytic shellfish poisoning; phytoplankton; floraWhite, A.

A red tide caused by Mesodinium rubrum was observed in Passamaquoddy Bay, New Brunswick, during August 1975. The chlorophyll and phycoerythrin composition and ultrastructure of the endosymbiotic alga are similar to those described for M. rubrum from Ecuador and British Columbia, including the fact that the endosymbionts do not appear to contain a nucleus. Special ultrastructural features are a complete endoplasmic reticulum surrounding symbiont chloroplast, pyrenoid, and starch bodies, ciliate trichocysts with electron-dense and electrontranslucent regions, and curious symbiont mitochondria-ciliate macronuclei associations.

Carapace measurements of lobster larvae caught in the western part of Northumberland Strait showed that in this area the natural growth in length per moult is 34.4 per cent from stage 1 to stage 2, 31.8 per cent from stage 2 to 3, and 30.3 per cent from stage 3 to 4. The seasonal distribution of the first four larval stages was determined from plankton tows made continuously from mid-June to late September each year from 1948 to 1952. To determine natural annual growth, lobsters of 15 to 25 cm., total length, were sorted into five or six size groups and were distinctively marked by means of holes punched through the tail fan. These were liberated on six widely separated fishing grounds in the Maritime Provinces. Recoveries of these marked lobsters four to twelve months after release showed that in the southern Gulf of St. Lawrence, 15 to 20 cm lobsters grew 8 to 9 mm. (13 to 15 per cent) in carapace length, 22 to 25 mm. (13 to 14 per cent) in total length and 80 to 95 grams (45 to 53 per cent) in weight. In southern Nova Scotia and Grand Manan 20- to 25-cm. lobsters grew 10 to 12 mm. (13 to 15 per cent) in carapace length, 27 to 34 mm. (12 to 15 per cent) in total length and 170 to 220 grams (43 to 54 per cent) in weight. From the carapace length of 4th-stage larvae and straight-line equations relating carapace length before moulting and carapace length after moulting, the average carapace lengths of lobsters in stages 5 to 20 were calculated. From observations and calculations on the growth per moult and moulting frequency, it is estimated that in the Northumberland Strait area lobsters reach a length of 14 cm. (5 1/2 in.) at the end of the fifth growing season (4 1/2 years old) and 24 cm. (9 1/2 in.) at the end of the ninth growing season (8 1/4 years). lobsters; growth rate; Northwest Atlantic; crustaceans; shellfish; invertebrates; fauna; moultWilder, D. G. (1960).

Lobster stocks outside Passamaquoddy Bay are not expected to be affected by the proposed development. Within the bay, the hatch, survival and settlement of larvae are expected to increase. An increased rate of exploitation, a modest increase in poundage of commercial landings, and a decrease in the average size of the lobsters caught are to be expected. The use of the bay as an important commercial collection, storage and distribution centre for live lobsters will be seriously affected. tidal power; lobsters; Passamaquoddy; Quoddy; economics; crustaceans; shellfish; fauna; invertebratesWilder, D.

The state of knowledge of marine and estuarine sublittoral benthic synecology may be said to be still in a descriptive stage of study. Much of the recent literature of the subject concerns either qualitative and quantitative descriptions of communities or associations, or concepts of such associations including diversity, stability and succession. It is the purpose of this paper to present a theory, based on a hierarchy of multiple limiting physical and biotic factors, for study of the controls governing community composition, biomass and productivity. Three major biotic factors are considered as qualitative and quantitative controls: food supply, supply of colonizing larvae, and interspecies competition. They are discussed and new techniques are suggested which may help in understanding the mechanisms of control. subtidal; benthic; Fundy; ecology; fauna; invertebrates; vertebratesWildish, D. J.

With respect to the first proposals in the 1920s, to dam Passamaquoddy Bay for tidal power generation, Huntsman (1952) posed the right question: "How are the fisheries of the Bay of Fundy produced and what will be the effect of damming on fisheries production?" This presentation is an attempt to see whether the question can be answered today and, if not, what further research is needed to do so. tidal power; Passamaquoddy; Quoddy; fisheries; ecology; Fundy; subtidal; vertebrates; invertebrates; faunaWildish, D.

The reproductive bionomics of two Canadian sublittoral amphipods, Casco bigelowi and Leptocheirus pinguis, are compared in a Bay of Fundy estuary. Casco is semelparous and Leptocheirus iteroparous, although both have a biannual life history. The relatively high reproductive potential of each species, Casco with a reproductive potential of 12.5 and Leptocheirus with 25.5 young per year, is dictated by a combination of wave-caused sediment washout and predation within the estuary. reproduction; Fundy; estuarine; invertebrates; fauna; benthic; subtidal; faunaWildish, D.

Study of the fauna and flora living near the interface between sedimentary substrates and seawater, below the reach of the lowest tides, dates from before the first Challenger expedition in 1872. Although the early studies were of purely scientific interest (perhaps enhanced in the minds of the pioneers by the difficulties of sampling), a renewed interest in benthic biology has blossomed in the last 25 years. This results at least partly from the realization that benthos, by their distribution patterns, provide a record of man-made impacts such as pollution because mature, benthic infauna are unable to move away from polluting sources. It was recognized early that benthic production is a major contributor to groundfish production (Petersen and Jensen 1918). Another focus of interest is from recent sedimentary geologists who need to study contemporary animal-sediment interactions to fully understand the stratigraphic record (see Johnson 1978).Despite this interest in subtidal benthic biology, sampling techniques have changed little since the Challenger expedition sailed, although the introduction of the first quantitative grab (Peterson and Jensen 1911) may be said to date the origin of the subject as a scientific study. Since 1911 many novel methods have been tried, but all have limitations serious enough to discourage their general use among benthic biologists. Because of this and perhaps also because of the youth of the subject and the relatively few scientists involved at any one time, a satisfactory conceptual base has yet to emerge (Wildish 1977). This state of affairs should attract any embryonic marine biologist worth his salt to this field where so much has yet to be achieved by so few.
This chapter concerns the sublittoral animals of estuaries and the near-shore of the Bay of Fundy which live attached at the sediment-water interface, the epibenthos, or which live within the sediment, the infauna. Benthic animals may be classified arbitrarily by their body dimensions, since sieves are commonly used to separate them from the sediment matrix in which they live. The following classes are recognized throughout this work (adapted from Wolff 1977):..... subtidal; fauna; benthic; oceanography; Fundy; ecology; invertebrates; sediments; hydrography

Seasonal observations for tidal periods of 12 or 24 h in, or near, Bay of Fundy salmonid mariculture sites were made. Variables measured included dissolved oxygen, salinity, temperature, chlorophyll a, current velocity, dissolved inorganic nitrogen, phosphate, and silicate. Levels of nitrate, phosphate, and silicate were not increased by the salmonid mariculture industry above those typical of the oligotrophic Bay of Fundy, although ammonia levels were higher near the salmon net pens. During the summer, levels of silicate and dissolved inorganic nitrogen were diminished coincident with uptake by the microalgal bloom. aquaculture; Fundy; salmon; fish; vertebrates; fauna; oceanography; hydrography; salinity; temperature; nutrientsWildish, D.

A quantitative hypothesis is presented that current velocity and roughness at the sediment-water interface control the numbers, biomass, and growth of suspension-feeding macrobenthic animals. The controls are the effect of tidal currents on turbulent mass transfer of food to suspension-feeding animals and direct inhibition of growth and settlement by currents in excess of 12-30 cm/s. The rate of turbulent supply of ATP associated with seston is proposed as a practical way of determining growth potentials of suspension feeding macrobenthos at current velocities <30 cm/s. tides; feeding; benthic; fauna; subtidal; Gulf of Maine; vertebrates; invertebrates; growth rate; ecologyWildish, D.

The relationship between ambient seawater flow velocity and growth of the giant scallop Placopecten magellanicus Gmelin is shown to be a reverse ramp function with growth inhibition at flow velocities of >10-20 cm/s. The mechanism of inhibition involves a reduction in ration as velocities around the scallop increase. In ambient flow which are sufficient to cause overloading of the scallop gill, the feeding/filtration rates is reduced by an unknown mechanism, possibly involving the mantle edge closing or a gill bypass mechanism operating. scallops; molluscs; growth rate; tides; Gulf of Maine; invertebrates; fauna; shellfish; bivalvesWildish, D.

Negative redox values, indicating microbial denitrification respiration, were present at three of nine salmonid farm sites investigated. Uneven distribution of redox values within sediment cores can be explained by periods of net depositional and erosional activity. A temporal study of phytoplankton species number and density at 12 sampling stations within the Western Isles region was initiated beginning in May 1987. It is hoped that the phytoplankton data can be used as a benchmark against which to measure possible future changes of species spectra and density. salmon; Fundy; aquaculture; fish; plankton; vertebrates; faunaWildish, D.

An identification strategem for benthos collected to assess marine and estuarine pollution, Fisheries Research Board of Canada (No. 450), Fisheries Research Board of Canada.
An identification strategy for benthos collected to determine some biological effects of pollution is presented. The concept is illustrated with sublittoral infauna collected during 1969 to 1972 to assess the effects of a pulpmill effluent in L'Etang Inlet, New Brunswick, Canada.The tabular key method of Newell was modified to provide rapid, accurate identifications with the least number of character states possible. Information from the developing key was computer compatible, allowed the user to reach the primary ecological and toxicological literature for given taxa and avoided information redundancy because it applied in a specified geographical area at a specified time.

Local extinction of the eukaryotic macrofauna in L'Etang Inlet, New Brunswick, as a result of anoxia or hypoxia caused by the presence of pulp mill effluent is described. Temporal changes of species composition, including repopulation by opportunistic anoxia-tolerant species, are described. The ecological relevance of the changes is assessed by computing the standing crop and production potentially available to fish and invertebrate carnivores lost in the affected zone.The precise stage during the development of anoxia causing local extinctions was not determined in this study. Circumstantial evidence implicates low dissolved oxygen, presence of hydrogen sulfide, and changes in microbial food affecting larvae or adults.

A multi-disciplinary study of pollution in L'Etang estuary caused by sulfite pulp mill effluent is reported. The pulp mill indirectly caused closure of a soft-shell clam fishery and has made the landward 4 km of the estuary completely anoxic, giving rise to offensive air pollution. Remedial measures are suggested which would eliminate these two major multiple-use resource conflicts. From the point of view of aquatic resource management, the results emphasize the need for careful consideration of siting point source effluents, the further development of numerical simulation techniques for predictive purposes, and long-term planning for water resources.

Four final grow-out methods for culture of the giant scallop (Placopecten magellanicus) were tested in small, pilot scale trials at two locations near St. Andrews, New Brunswick. With all of these methods: long-lines anchored by concrete blocks, weir-pole stakes, benthic cages and benthic relaying, it was biologically feasible to produce market-size giant scallops. Based on their pilot scale experience, the authors have attempted an economic analysis of each final grow-out method employed. Ten-year predictions show only one of the four grow-out methods, benthic relaying, to be economically feasible. scallops; molluscs; aquaculture; Quoddy; Passamaquoddy; economics; invertebrates; fauna; shellfish; bivalvesWildish, D.

Salmonid net-pen sites located above a depositional sediment rapidly accumulate deposits consisting of silt/clay particles, salmonid faecal matter and food wastes. This material, with its biotic community (mariculture sludge), appears to be similar to the sewage sludges of freshwater environments. The redox (Eh) values within mariculture sludges are typically negative and analysis of gases escaping from the sludge shows that they included: methane, nitrogen, carbon dioxide and hydrogen sulphide. Our studies show that the predominantly chemical oxygen demand of mariculture sludges can be a significant factor influencing the dissolved oxygen budget of salmonid net-pen sites in the Bay of Fundy. aquaculture; salmon; Fundy; contaminants; fish; vertebrates; fauna; sediments; nutrients; pollutionWilley, A.

From the introduction:Few imagine, when crossing the ocean, that the prow of the ship is cleaving its way through teeming myriads of foamlike creatures and that every turn of the screw is a marine catastrophe, bringing sudden death to multitudes of sensitive beings.
That this is a fact is frequently demonstrated in the darkness of the night when the swarm of life approaches nearer the surface which it illuminates by phosphorescent scintillations.
An ingenious method of testing the vitality of the sea from the seemingly unfavourable situation of a passenger on an ocean liner, has been adopted in recent years by Professor Herdman of Liverpool, the founder of the successful Marine Biological Station at Port Erin (Isle of Man). The method simply consists of straining the sea-water as it flows from a tap through a silk bag, at intervals during a voyage.
Even in the daytime, in calm weather, the presence of living matter may, be made manifest by the occurrence of smooth oily-looking streaks and patches in the midst of the rippling water. The remarkable character of these so-called animal currents was first recognized by Carl Vogt as long ago as 1848. A graphic description of their appearance around Lanzarote, one of the Canary Islands, was published by Professor Richard Greeff in 1868. Similar streaks may be observed in the bay of St. Andrews; they are due in part to the tidal currents and in part to the organisms which are contained in them.
The floating fauna and flora of the oceanic and coastal waters consitute what is known as the Plankton of drifting life of the sea. This technical term, which is now universally employed at Biological Stations, was introduced by Professor Victor Hensen of Kiel in 1887. The only single vernacular term, previously in use, which conveyed the same meaning, was the German word 'Auftrieb', this was commonly borrowed by other tongues, and the custom of using it continued for several years after the more international expression 'Plankton' had been happily suggested; but now it is seldom heard.

No abstract available. From the introduction:The first part of these studies was published in Contributions to Canadian Biology, New Series, Vol. I, pp. 305-334, 1923. There are one or two corrections which I take this opportunity of inserting here. The species named by me Laophonte calamorum n. sp. is the same as Laophonte Mohammed, Blanchard et Richard, from sale lakes of Algeria, since found elsewhere in the palaearctic region. At the time of writing I was unacquainted with the original description. The species uncertainly referred to Epischura nevadensis (op. cit. p. 310) should be an immature stage of Epischura lacustris. In another paper on Northern Cyclopidae and Canthoacamptidae (Wiley, 1925), the species named Cyclops bissextilis n. sp. (p. 141) is the same as Cyclops crassicaudis, G.O. Sars.
Owing to the extent of the tides, the Bay of Fundy offers exceptional opportunities for the study of bottom-feeding species, which are not less valuable in their own sphere than are the calanoids of the open sea. Not only do rockpools serve as inshore nurseries for numerous broods of young harpacticoids, but by gently creaming off, with a spoon, the exposed surface layer of the fine, moist sand between tide-marks, many of the characteristic forms are to be found, often in couples, the male grasping some part of the body of the female with his prehensile antennae. The particular mode of amplexus varies somewhat from one species to another. The mud-flat where they are collected was swarming with the amphipod Corophium volutator. copepods; Fundy; invertebrates; zooplankton; fauna; mudflats

(Charadriiformes: Scolopacidae)." Can. J. Zool. 66(10): 2265.
Skrjabinoclava morrisoni of the proventriculus of semipalmated sandpipers (Calidris pusilla) developed to the infective stage in the marine amphipod Corophium volutator. The first moult occurred 8 d and the second, 11 d postinfection at 20 degree C. In the final host, fourth-stage larvae were recovered from one experimental bird examined 8 d postinfection. Juvenile birds collected at Long Point, Ontario, were not infected with S. morrisoni suggesting that transmission may not occur on the breeding ground. Transmission occurs, however, in the Canadian Maritimes and the Gulf of Mexico, as evidenced by the presence of juvenile S. morrisoni in birds collected on Grand Manan Island, New Brunswick, and birds recently arrived at Delta Marsh, Manitoba, from the Gulf Coast. shorebirds; birds; parasites; Grand Manan; Fundy; Quoddy; vertebrates; fauna; moultWoodley, T. H., M. W. Brown, et al. (1991). "Organochlorine levels in North Atlantic right whale (Eubalaena glacialis) blubber." Arch. Environ. Contam. Toxicol. 21(1): 141.
Polychlorinated biphenyls (PCBs), total DDT (DDT + DDE + DDD), dieldrin, heptachlor epoxide, chlordanes, and hexachlorobenzene (HCB) were found in blubber biopsies from endangered North Atlantic right whales (Eubalaena glacialis) in the Bay of Fundy and on Browns-Baccaro Banks. Analyses included four sex and age class composite samples from 1988, and 21 individual samples from 1989. Generally, PCBs demonstrated the highest wet weight residue levels (up to 1.9 mu g/g), followed by total DDT (DDT + DDE + DDD) (trace to 0.47 mu g/g). Relatively low residue levels in adult females suggest that transmammary organochlorine (OC) residue transfer occurs during lactation. The actual blubber residue loads may have been underestimated, because the samples were taken when the whales were depositing fat reserves and the samples may not have been representative of the remainder of the blubber. toxins; whales; cetacea; Fundy; Northwest Atlantic; marine mammals; vertebrates; faunaWorley, I. A. (1982). Botanical and ecological aspects of coastal raised peatlands in Maine and their relevance to the Critical Areas Program of the State Planning Office, Maine Critical Areas Program (No. 69).
The coastal raised peatlands of Maine are ecologically, scientifically, educationally, and aesthetically significant natural features restricted to a very narrow strip of Maine's eastern coast from the tip of Mount Desert Island to West Quoddy Head. Rare in North America, these peatlands are most similar, in vegetation and morphology, to coastal plateau peatlands in extreme southwestern New Brunswick, coastal Nova Scotia, and western Newfoundland.This report defines criteria by which the scientific, scenic, and natural attributes of the coastal raised peatlands can be assessed, and recommends peatlands for evaluation under the Maine Critical Areas Program based upon such an assessment. An inventory of all coastal raised peatlands in Maine was performed based upon a literature search and field work. Two hundred twenty nine peatlands were considered, 159 overflown, and 59 visited. Eighteen sites, including 21 peatlands, are recommended for evaluation for inclusion on the Register of Critical Areas. Eighteen additional sites are likely of similar significance, and these areas should be field checked for possible evaluation for inclusion on the Register of Critical Areas as soon as field work is possible. The Shrub Slope peatlands of extreme outer islands and points are recommended for study by the Critical Areas Program. At least 53 additional coastal raised peatlands are in an essentially unaltered natural state; should additional features of significance be discovered at some future time, some of the sites may be considered then for evaluation as potential Critical Areas. Immediate protective management at high use peatlands, notably Big Heath in Acadia National Park, peatlands on Great Wass Island, and Carrying Place Cove Bog is strongly recommended.

American eel (Anguilla rostrata), chain pickerel (Esox niger), white perch (Morone americana), yellow perch (Perca flavescens), brook trout (Salvelinus fontinalis), and Atlantic salmon (Salmo salar) contained 0.07-2.08, 0.27-1.58, 0.75-1.07, 0.20-1.05, 0.08-0.13, and 0.09 ppm of methylmercury, expressed as mercury on wet weight basis, respectively. With only two exceptions. Levels of methylmercury in marine fish were below 0.13 ppm. Some of the freshwater sampling locations could be directly associated with an industrial activity in the area, whereas others suggested pollution by airborne mercury. However, the concentration of methylmercury in eels from a lake in New Brunswick did not change over a period of 46 years, indicating that elevated levels of mercury may in some instances reflect the natural situation. toxins; metals; fish; pollution; Fundy; contaminants; vertebrates; fauna; eelsReturn to Cobscook Bay Resource Center homepage.
