Determination of population structure and stock composition of chum salmon (Oncorhynchus keta) in Russia determined with microsatellites
Variation at 14 microsatellite loci was examined in 34 chumsalmon (Oncorhynchus keta) populations from Russia and evaluated for its use in the determination of populationstructure and stock composition in simulated mixed-stock fishery samples. The genetic differentiation index (Fst) over all populat...
