Substantial genetic variability among populations of chum salmon (Oncorhynchus keta) around the Pacific Rim make it possible to estimate the stock composition of complex mixed-stock fisheries using genetic stock identification (GSI) techniques. We briefly discuss the history of the use of portions or all of the Asian-North American baseline for protein genetic characters to resolve mixtures of chum salmon. We use the species-wide genetic database to analyze test fishery samples taken aboard Japanese research cruises in 1991-1992 in the Kurillslands (145 E), the western North Pacific Ocean (165 E), and the North Pacific Ocean and Bering Sea at 179 30' W. Mixture samples from the Kuril Islands and western North Pacific Ocean were dominated (>75%) by single stock groups, i.e., Japanese and Russian stocks, respectively. At 179 30' W, the stock profile in the Bering Sea was 45% Japanese, 38% Russian, and 15% Alaskan and differed considerably from the samples (19911992) taken in the North Pacific Ocean (15% Japanese, 62% RuSSian, and 22% Alaskan). This protein genetic dataset has been standardized across international agencies and can be used across the species' distribution for accurate mixed-stock fishery analyses. Results from genetic stock identification can and are being used fisheries management and applied to biological models of stock distributions of salmon in the North Pacific Ocean.
