Study of variability of size-age indices and polymorphism of 6 microsatellite loci, 5 loci of SNP, and accidentally amplified polymorphic DNA (RAPD) of sockeye salmon Oncorhynchus nerka of three largest populations from the western coast of Kamchatka Peninsula was performed. The efficiency of using different types of markers for the differentiation of populations and determination of the population belonging of sockeye salmon from lake-river systems of western Kamchatka was analyzed. Significant interpopulation differences were revealed from the frequencies of alleles of genetic markers and from a set of biological indices. It was established that genetic markers are characterized by a better differentiating capacity, as compared to biological characteristics. The most satisfactory results during determination of population belonging of sockeye salmon were obtained using an integrated data base of allele frequencies of microsatellite and SNP loci. © 2010 Pleiades Publishing, Ltd.
