Population structure of sockeye salmon Oncorhynchus nerka in Barkley Sound, British Columbia, Canada was examined by analysis of microsatellite variation at 14 loci in three populations sampled in each of 3 years. The mean F ST over all 14 loci was 0·063. Differences among populations accounted for 12 times the variation observed among years within populations. The number of alleles present at a locus was related to the power of the locus to provide accurate identification of individuals to population. The more alleles that were present at a locus, the greater was the power of the locus for individual identification. Individuals were correctly classified to one of three lakes of origin at a rate of 89%, and to one of two river drainages at a rate of 96%.
