Microsatellite Variability of Pacific Herring Clupea pallasii Valenciennes, 1847 from the Sea of Okhotsk and Bering Sea

The genetic variability of ten microsatellite loci was examined in samples of the herring from the Sea of Okhotsk and the Bering Sea. All loci were polymorphic; the expected heterozygosity estimates varied in the range of 0.3-94.3% (mean 66.7%). The degree of genetic differentiation of the herring was statistically significant (theta = 1.38%). The level of pairwise genetic differentiation F (ST) was-0.002-0.046; R (ST) was-0.003-0.166. Genetic differentiation of the herring from the Sea of Okhotsk and the Bering Sea correlated with the spatial-geographic structure of the species in the studied range on the basis of F (ST) (P = 0.001).
