Interregional differentiation of chum salmon from Sakhalin and South Kurils inferred from microsatellite markers
ABSTRACT Variability at ten microsatellite loci was examined in wild and hatchery populations of chum salmon (Oncorhynchus keta Walbaum) from the Sakhalin Island and Southern Kuril Islands, Iturup and Kunashir. Substantial genetic differences between
Sakhalin and South Kurils chum salmon (the differentiation reached 6.0%) were revealed. Statistically significant differences
between chum salmon from Iturup and those from Kunashir were demonstrated, as well as between the chum salmon populations
from different rivers within the islands. It was shown that in different types of population comparisons, different marker
sets were most informative.
