Genetic variations among pacific herring (<i>Clupea pallasii Val</i>.) from the Okhotsk Sea and Lake Ainskoye by microsatellite loci

Abstract

Genetic variation among spawning groups of pacific herring from different spawning grounds in the northwestern Okhotsk Sea and Lake Ainskoye (Sakhalin Island) is assessed by 11 microsatellite loci. All loci were polymorphic. Genetic differentiation of the herring from the Okhotsk Sea was statistically significant, the pairwise genetic differentiation FST varied in the range of 0.0-0.4 that suggested existence of at least two local stocks. The herring from Lake Ainskoye was clearly different from the Okhotsk Sea herring.
