Population samples of chum salmon from the hatcheries of Sakhalin Island genetically differentiate at ten microsatellite markers (p0,001). The populations from southwestern Sakhalin are least heterogeneous, having less number of alleles and less heterozygosity. Genetic differentiation of the populations studied is in agreement with their geography: in a plot of principal components, they form distinct groups that correspond to 4 regions of Sakhalin Island (south-western, southern and south-eastern, eastern, and north-eastern). This indicates genetic identity of chum salmon of each of these regions that remain to exist despite gene flow between the hatcheries due to transplantation. The data received can be used as a start point for a follow genetic monitoring of chum salmon from the hatcheries
