The inner Bay of Fundy and Minas Channel are practically devoid of locally produced zooplankton. The few plankters present are either estuarine species from Minas Basin and Chignecto Bay or immigrants from the Gulf of Maine. The former (Acartia tonsa, Eurytemora herdmani, Centropages hamatus, Pseudodiaptomus coronatus and Canuella canadensis) are abundant inland with shallowing and heavy river discharge. The latter (Calanus finmarchicus, Sagitta elegans, Pseudocalanus minutus, Oithona similis and Parafavella gigantea) all show a similar distribution, being abundant in the mouth of the Bay, but declining greatly going inward. Also, Calanus specimens from the inner Bay have little or no fat, which indicates a lack of food there.The extreme paucity of all zooplankton in Minas Channel is apparently caused by heavy and deep turbulence, which prevents development of phytoplankton on which the animals depend for food.

<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.

Resonant Region

A near-resonant mode of oscillation extending to the continental shelf in the Gulf of Maine is shown to be a contributing factor in the extreme high M2 tidal ranges in the Bay of Fundy.The effect on the M2 tidal regime of a double barrier at Cape Chignecto is studied by two methods. A one-dimensional simple harmonic model shows the effect of placing the matching boundary at any intermediate position and defines a probable zone of values for the barrier amplitude. A two-dimensional calculation covering the entire resonant region gives an estimated amplitude reduction of 34% at the Cape Chignecto barrier site.
