Abstract
Analysis of population structure and stock identification has been carried out by a number of different methods. In this study, we used SNPs in 730bp long sequences of the mtDNA COIII-ND3-ND4L region in order to examine genetic diversity and population structure of the chum salmon in the North Pacific. In a total of 201 individuals analyzed, 48 from Korea, 44 from Japan, 45 from Alaska, 29 from Canada, 20 from Washington (USA) and 15 from east Sakhalin (Russia), as many as 55 variable sites comprising 51 different haplotypes were identified. Some of the haplotypes were population-specific so that they can be used for stock identification. Canadian and one of Korean populations showed relatively high level of haplotype diversity (h=0.70±0.11 ~ 0.92±0.06) while Russian and one of the Korean populations showed low variability (h=0.37±0.15 ~ 0.42±0.16). Pairwise FST and AMOVA analyses of the populations revealed that Korea and Japan chum salmon are genetically indistinguishable and so are Russia, Alaska, and Canada salmon (FST<0.1). Therefore, we suppose that the chum salmon populations in the North Pacific can be grouped in general into three genetic population units, Korea-Japan unit/Russia (east Sakhalin)-Alaska-Canada unit/Washington (USA) unit.
