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.

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.

Population Sizes

The relative abundance of berried female lobsters, Homarus americanus, and their contribution to total egg production in various areas of the Bay of Fundy and off southwestern Nova Scotia are estimated from sampling commercial and research cruise catches from traps. Concentrations of berried females occurred on Browns Bank, Georges Bank, and the New Brunswick side of the Bay of Fundy. To a lesser extent, berried females occurred in the coastal areas of southwestern Nova Scotia. Using a range of mortality values, a variety of population sizes were estimated from 1983 landings from which relative egg production values were calculated for each area. Lobsters from coastal waters of southwestern Nova Scotia combined with the Bay of Fundy were estimated to produce between 23 and 53% and those from the offshore Brown and eastern Georges Banks to produce between 47 and 77% of the region's total egg production. The results suggest that lobsters in each area are capable of producing large numbers of eggs. Where the resulting planktonic larvae settle as benthic juveniles is unclear.

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.

<i>Abstract</i>.—The Gulf of Maine (GoM) may have defined borders to some, but to the Canadian fishing industry, it carries a flow of larvae, nutrients, and other resources that help sustain the fishery from Georges Bank to the West Scotian Slope to the Bay of Fundy and all points in between. The GoM provides a source of wealth to people and communities, as well as supplying what may be one of the last natural foods on the planet. The fishing industry has been using the GoM for centuries, yet it is only recently that monitoring and data gathering has been taking place. In my opinion, we can extract much more value from the fisheries than we presently do. If the fisheries resource of the GoM is not delivering its full potential, who is ultimately responsible and accountable? In the past decade, transboundary groundfish resources from Georges Bank have been successfully managed through the Transboundary Management Guidance Committee. We can improve decision making even further in a greater ecosystem context, recognizing that decisions have to be made with the information available. An ecosystem approach to fisheries proposes a pragmatic view based on assessing the risk of not meeting agreed objectives.
