The genetic stock identification study began the development of a data base during fiscal year (FY) 1981 for use in estimating the proportions of chinook salmon stocks of the Columbia River drainage in ocean fisheries.  Genetic data were collected from 36  coastal stocks of chinook salmon in California, Oregon, Washington, British Columbia, and Alaska and from 9  stocks of the Columbia River drainage.  These collections provide  1) a preliminary data base for those non-Columbia River stocks that may contribute to ocean fisheries in which Columbia River fish are harvested, and  2) the addition of data for new loci to the existing Columbia River data base.  Evidences of genetic differences between Columbia and non–Columbia River stocks that would be useful in the analysis of ocean mixed fisheries were illustrated.  Data collection is continuing and will result in a data base sufficient to perform mixed fishery analysis of ocean fisheries in FY82.
