Monitoring of genetic and phenetic variety of chum salmon Oncorhynchus keta (Walbaum) from Tauysk Bay rivers of Ohotsk sea

Results of paleocrystic monitoring of genetic and phenetic variety of chum salmon from the rivers of Tauysk bay of Okhotsk sea are generalized. Interannual distinctions on genetic and phenetic markers in populations of chum salmon from the rivers Tauy, Yana and Ola are found out. It is shown, that each population has the features in exhibiting the interannual heterogeneity. It is noted, that now a variety of chum salmon in the specified populations is within the limits, comparable with average paleocrystic values. It testifies, on the one hand, to low efficiency of artificial reproduction, and on the another - shows, that historically generated interpopulative structure of the researched chum salmon is rather stable.
