Dynamics of Native Indian Food Fisheries on Salmon in British Columbia

Basic components of predation processes are briefly reviewed and data on these components are presented for several native Indian food fisheries. Depensatory mortality emerges as a common effect of these fisheries, which supports findings of earlier workers on Skeena River sockeye salmon (Oncorhynchus nerka). Native food fisheries therefore operate like natural "Type II" predators, and descriptive equations are provided for use by salmon managers and modelers.Key words: fishermen as predators, native, Indian, food, fisheries, salmon, depensation
