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.

Platorchestia platensis (Amphipoda, Talitridae) was previously known ecologically as a wrack generalist, but here we describe a secondary driftwood ecotope for this species. The trophic dependence of driftwood-acclimated P. platensis on rotting wood was confirmed by successfully culturing it within driftwood, without further addition of food. The stranded driftwood in which P. platensis was found contained gribble burrows (round and of 0.6 to 5 mm diameter). We hypothesize that P. platensis used the empty gribble burrows for interspecific squatting (to gain initial entry to driftwood and for shelter). We found eleven driftwood depositories in a 230 km length of shoreline in Passamaquoddy Bay. The commonest driftwood was of spruce and eastern white cedar. The small marsh at Hartley Cove contained a driftwood depository, where the new driftwood ecotope was discovered. This site was studied temporally to understand how wind and tidal forces might affect import and export of driftwood.

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.

Water transports in the passages connecting Passamaquoddy Bay and the Bay of Fundy were measured by the electrical potential differences induced in the water moving across the earth's magnetic field. A phase difference between the transports in Letite and Western Passages was observed, slack water occurring later in Western Passage by 15 to 60 minutes. Variation of the transport with time for each passage was studied. A marked harmonic content was found, particularly of the second and third harmonics with periods six (6.2) and four (4.1) hours, and was evaluated by harmonic analysis.The harmonic component content of the tidal current transports in the Saint Croix Estuary was found to be in close agreement with that of the observed tidal heights at St. Andrews, N.B. The harmonic content of the transports in Letite Passage and in Western Passage was related to hydraulic or frictional tidal flow and to shallow-water tides respectively. Currents in Letite Passage found at anchor Sta. 51 and deduced from the square root of the head measured by tide staffs were consistent in form and phase with data from the electrode voltages.A small residual transport from Passamaquoddy Bay through Western Passage was inferred with some uncertainty.

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.

Abstract Martin, J. L., and LeGresley, M. M. 2008. New phytoplankton species in the Bay of Fundy since 1995. – ICES Journal of Marine Science, 65: 759–764. A monitoring programme was initiated in 1987 to study phytoplankton populations in the Western Isles region of the Bay of Fundy, southwest New Brunswick. Samples are collected weekly from May through October, and monthly during the remaining months, to determine phytoplankton distribution and abundance at Brandy Cove, Lime Kiln Bay, Deadmans Harbour, the Wolves Islands, and mid-Passamaquoddy Bay. Since the programme was initiated, several previously absent or non-indigenous species have been found, suggesting that new species may have been introduced to the area. In order to establish a baseline for species indigenous to Bay of Fundy waters, we have taken a conservative approach and termed species reported for the first time in the Bay of Fundy system since 1995 as “new” species. New species include the following: (dinoflagellates) Alexandrium pseudogonyaulax, Amphidinium carterae, A. sphenoides, Ceratium macroceros, Polykrikos schwartzii, Preperidinium meunieri, Protoperidinium crassipes, and Pyrocystis lunata; (diatoms) Attheya septentrionalis, Attheya longicornis, Chaetoceros radicans, Cylindrotheca gracilis, Grammatophora serpentina, Lithodesmium undulatum, Mediopyxis helysia, Membraneis challengeri, Neodenticula seminae, Odontella sinensis, Proboscia eumorpha, Pseudo-nitzschia subpacifica, Pseudo-nitzschia fraudulenta, and Thalassiosira punctigera.

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.

Average Size

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 30.9 × 106 kw. is transmitted into the bay of which 1.26 × 106 kw. is transmitted into Passamaquoddy Bay. Work is done on the moon at the rate of 2.48 × 106 kw. and 0.03 × 106 kw. is used to maintain the mixed state in the waters of the Bay of Fundy. The remaining 27.1 × 106 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" (Z0) 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.)

Enteromorpha Linza

Pieces of the fronds of Enteromorpha linza, a green alga, growing just beneath the surface of the sea, of Porphyra umbilicalis, a red alga, of which the fronds of brownish-red colour which were growing on the side of a dock at half-tide level were selected, and of Delesseria sinuosa, a bright magenta-red alga from a depth of 18 metres in Passamaquoddy bay, were placed in vials of sea water (previously brought to pH 7 by the addition of KH2PO4), behind Corning red, green and blue filters, which had been brought to equal intensity in the photosynthetically active part of the spectrum, and exposed to sunshine. The gain in pH, due to the using up of CO2, was read at the end of 10 minute periods with a B.D.H. capillator set, and the photosynthetic rates for each species were determined by dividing the gain in pH (in hundredths of a unit) by the time. The photosynthetic rates of these three species in the different regions of the spectrum were very different, those of E. linza being red = 1.80; green = 0.16 and blue = 1.16, of P. umbilicalis red = 2.46; green and blue = 1.65, and of D. sinuosa red = 1.35; green = 1.25 and blue = 1.05. These data fit in very well with the transmission coefficients for red, green and blue light in the bay of Fundy at the place where the experiments were carried on, as green light penetrates best, blue next and red least.
