Book excerpt: "Bristol Bay Management Area supports the largest sockeye salmon Oncorhynchus nerka fishery in the world. Alaska Department of Fish and Game is responsible for managing fisheries under the sustained-yield principle. Sockeye salmon stocks in Bristol Bay can be exploited at rates up to 80%, so accurately estimating the stock composition of catch is critical to determining the total run (catch and escapement) of each stock. Accurate estimates of total runs are vital for managing under the sustained-yield principle because they provide the basis for establishing and meeting escapement goals. In recent years, the department has developed a genetics program for sockeye salmon in Bristol Bay to develop and apply genetics methods to identify the stock composition of commercial catch in the five commercial fishing districts. Here we present genetic results from 2009, compare them to results from 2006 through 2008, and to those based on traditional age-based methods"--P. 1.
