Genetic differentiation among chum salmon, Oncorhynchus keta (Walbaum), from Primorye and Sakhalin
Mitochondrial DNA (mtDNA) was examined in six wild populations of chum salmon ( Oncorhynchus keta Walbaum) distributed over the Primorye Region which extends approximately 1000 km along the Sea of Japan coast, and six populations from Sakhalin, using restriction enzyme analysis. By means of two rest...

Mitochondrial DNA variants grouped the fish into two major clusters representing the Primorye and Sakhalin regions.
