Passamaquoddy Bay

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. The life history pattern of N. americana in the inner Bay of Fundy was the same as that found in other areas nearby. It rarely occurred in depths greater than 75 m and was more abundant in the zooplankton at night than during the day. Because of the great abundance of N. americana in the inner Bay of Fundy and St. Mary's Bay, it provides an excellent food source for larval and adult fish in these areas.

Mean Time

From June 20 to November 21, 1957, 37,495 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 14.2 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.

History Of

A 4-year study of the life history of Thysanoessa inermis was conducted in Passamaquoddy Bay. A comparison of the growth pattern and eye morphology showed that Th. 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 Th. inermis (year class 0 animals) lives in the middle to upper layers and is morphologically different from the inermis form (year class I animals) which lives in the deepest layers.

Pleurobrachia Pileus

The distribution and relative abundance of Pleurobrachia pileus (O. F. Müller, 1776) and Beroe cucumis (Fabricius, 1780) within the Bay of Fundy and adjacent waters were examined over an 8-year period, either twice (spring and fall, 1975 and 1976) or three times (spring, summer, and fall, 1977 through 1982). 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. The larger numbers of smaller ctenophores within the upper bay and Grand Manan–Maine regions may reflect shrinkage of larger animals because of lack of food. Pleurobrachia pileus displayed a lack of significant affinity with the major recurrent group of zooplankton species found within the Bay of Fundy. 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.

A 615-cm male northern bottlenose whale (Hyperoodon ampullatus) stranded in Cobequid Bay, Bay of Fundy, in early October 1969. The skull, mandible, tympano-periotics, and teeth are described and illustrated. Five growth layers in the lower teeth place the animal below a growth curve based on samples from the Labrador Sea taken in May and June. A summary of nine other North American occurrences of 12 individuals, mainly south of Sable Island, indicates a winter migration to waters offshore of Massachusetts and Rhode Island.

Biological Factors

Crustacean and rotifer plankton assemblages of 93 lakes in Labrador, 107 in Newfoundland, and 142 in New Brunswick – Nova Scotia were investigated for evidence of correlations with lake morphometric, chemical, or biological factors. Labrador assemblages were almost completely lacking in identifiable structure. Newfoundland species clustered into two groups of different body size, suggesting the influence of fish predation. Only one species in Labrador and Newfoundland was significantly correlated with a derived factor related to lake water buffering capacity. New Brunswick – Nova Scotia species clustered into two groups, one featuring significant positive and the other significant negative correlations with the buffering factor. From this we conclude that acidification is having an impact on the limnetic zooplankton of these two provinces. Multiple discriminant analysis was used to demonstrate that New Brunswick – Nova Scotia lakes differing in their buffering capacity were also distinct in zooplankton composition. Lakes with low factor scores (low pH, alkalinity, and calcium) were mainly located in the Bay of Fundy region; this area has above average fog and precipitation, and lies within the summer air flow carrying pollutants from the south.
