Deep-Sea Fisheries: Perspectives and Lessons continental shelf fisheries. The ecological principles that pertain to life generally in the deep-sea are reasonably well known, but detailed life history information about individual species is only now accumulating. In many cases, heavy exploitation of deep-sea fishes has preceded such knowledge.

Fishing Down Marine Food Webs: An Updateisheries catches by small, short-lived fishes and invertebrates. As large fish tend to be top-predators, feeding on smaller fishes while smaller fish and invertebrates feed on plankton and/or detritus, this process, recently shown to be operating globally, has been called “fishing down marine food w

Ecological Implications of the Shellfishery; A Case Study on the West Coast of British Columbia, Canernments are under increasing pressure to diversify coastal community economies that previously relied on these two primary resources. The consequence is tremendous pressure to exploit yet another primary resource, the shellfishery. Common sense would suggest given our track record which demonstrate

Responses of Pelagic Marine Ecosystems to Climate Change — Can We Predict Them?imate change is twofold. First, planktonic ecosystems play a role in regulating greenhouse gases, especially in removing carbon dioxide from the surface ocean to the deep ocean via sinking organic particles, the so-called “biological (or biotic) pump.” Second, planktonic ecosystems operate as the ba
