Coho Fishing Opening On Willapa Bay Tribs

The Washington Department of Fish and Wildlife uses two different modeling tools to evaluate the runsize of coho in-season, based on the catch per unit effort (CPUE) of the commercial fisheries and the Terminal Area Management Model (TAMM) to estimate catch, impacts, escapement and harvest rates for each fishery by species preseason. The prediction from these models indicates a much higher coho runsize and coho natural origin escapement than predicted preseason.
