“…(Creaser et al 1984), and on juvenile mackremains, we agree with Smith and Gaskin (1974) that these erel, cod, silver hake, and Urophysis sp. (Leim and Scott items were secondarily introduced into the porpoise stomachs 1966).…”

We examined contents from stomachs of 127 harbour porpoises (Phocoena phocoena) caught in groundfish gill nets in the western Bay of Fundy during June to September, 1985–1987. Relative importance of prey species was assessed using both numerical and caloric measures. Atlantic herring (Clupea harengus) was the most important prey species, contributing 80% of the total caloric intake, with some spatial and temporal variation. Silver hake (Merluccius bilinearis) and Atlantic cod (Gadus morhua) were also important, but together comprised only 17% of the total caloric intake. No differences were found in relative prey importance between adult porpoises of different reproductive conditions, but lactating females ingested more fish and had a significantly higher total caloric intake than nonlactating females or mature males. The diet of porpoises collected from the same area in 1969–1972 consisted of a higher proportion of pelagic prey species and a lower proportion of demersal species. This may be attributed to differences in capture method, as the earlier sample of porpoises was collected at the surface, while the present animals were captured at depths of 45–100 m.

“…Herring tagging studies were first conducted by the Maine Department of Marine Resources (D.M.R.) between 1976-78 when 57,887 age 2+ herring were tagged and released at 34 sites along the Maine coast (Creaser et al, 1984). These studies were continued between 1980-82, when an additional 106,241 age 2+ herring were tagged and released at 38 sites along the Maine and New Hampshire coasts.…”

Between 1976 and 1982, 164,128 juvenile and adult herring were tagged and released at 72 sites along the Maine and New Hampshire coasts. Total recovery rates were 5.9%for juveniles and 4.9% for adults. Effective recovery rates (i.e. from the 15th day after release) were 4.1 and 3.5%. respectively. Migration patterns varied with season and region of tagging. Summer-feeding juveniles from all areas along the coast frequently moved into adjacent areas during the3rd and the 4th calendar quarters. Some of these juveniles then underwent an autumn migration to the southwest where they overwintered off the Massachusetts and New Hampshire coasts. Others overwintered off southwestern and northeastern Maine. There was a tendency for tagged fish to be recaptured east of the tagging site during the 2nd and 3rd quarters of the following year. Tagging studies on summer-feeding adults showed migration patterns similar to juveniles. There was a small but consistent tendency for some adult fish tagged in eastern Maine to be recovered in the Southwest Nova Scotian fishery. There was no evidence of changes in seasonal migration patterns of either juveniles or adults during the study period. Tagging studies on overwintering juveniles tagged in northeastern Maine showed that most recoveries during the following year were from the tagging area. Tagging studies on spawning herring tagged off New Hampshire and northeastern Maine showed that these fish overwinter off Massachusetts. Recoveries during the 3rd and 4th calendar quarters of the following year were in close proximity to the tagging area.

“…The age structure was narrower in the Georges Bank region (predominately ages 3-5) than in the Gulf of Maine where a greater proportion of immature (age 1 and 2) herring were captured in midwater trawls and a greater proportion of older herring were captured in bottom trawls. Juvenile herring tend to shallower water and/or more inshore areas than do adults (Creaser et al, 1984;Creaser and Libby, 1988), so Georges Bank juveniles may not reappear on Georges Bank until they mature. At the opposite end of the age spectrum, there appears to be fewer age 6 + herring in the Georges Bank region and why this is or should be so is not readily apparent from these data.…”

Atlantic herring (Clupea harengus) in the Georges Bank, Gulf of Maine, and southern New England regions were sampled from early September into mid-November by the Northeast Fisheries Science Center during their annual randomly-stratified bottom trawl and systematic acoustic/midwater trawl surveys. Atlantic herring were randomly selected for length distributions and systematically subsampled for biological metrics (e.g., weight, age, maturity, and sex). Broad similarities in Atlantic herring biological metrics between midwater and bottom trawl catches suggest both gear types provide comparable sampling of herring demographics in the Gulf of Maine and Georges Bank regions during autumn. Annual mean lengths and weights and temporal patterns of herring size were consistently similar between gear types. Similarity in age structure between Georges Bank and the Gulf of Maine suggest a similar response to intrinsic and extrinsic factors between herring stocks in these regions, but apparent asynchrony in spawning timing suggests some level of independence between these stocks. Overall similarities can mask interesting distinctions such as midwater trawls seem to sample younger, smaller, but heavier fish than do bottom trawls. Sampling of historical spawning sites appears to characterize the biological state of Atlantic herring in the Georges Bank region and could be utilized to design an efficient sampling scheme for Atlantic herring in the Gulf of Maine.
