There are 3 stocks of Pacific hake, Merluccius productus, in Canadian waters. In addition to the large offshore hake stock that migrates from the south to summer in Canadian waters, there is a small resident offshore stock that spawns in Canada and whose eggs and juveniles have been found by surveys in the Barkley Sound area. Isolated from the offshore hakes, an inshore, relatively under-exploited stock of hake inhabits the Strait of Georgia and Puget Sound, is distinguished by its otolith structure and lack of flesh parasites. On account of the importance of the fishery, the ecology of Pacific hake is relatively well documented, with at least 33 papers having been published since 1980. This account is confined to an evaluation of the literature in order to derive estimates of stock biomas, total mortality rate, and diet, in summer and winter, for input to an Ecopath model of the southern B.C. shelf.
