Genetic Identification of Juvenile Pink Salmon From the Sea of Okhotsk Basin Based on the Materials of an Autumn Trawl Survey in 2020

Data on the regional composition of marine mixed aggregations of young pink salmon in the Okhotsk Sea basin during the post-catadromic migrations in 2021 are presented. The high probability of significant prevalence of spawning returns of southern stock complex of pink salmon and sharp decrease of their returns to the northern regions in 2022 are revealed. Identification estimates of juvenile fish obtained from RFLP analysis of mtDNA and analysis of SNP-loci allelic variability were correlated with the values of actual regional catches and spawning runs. A close correspondence between calculated estimates and actual data for the northern herd complex was noted. Results of the genetic identification were somewhat underestimated for the Sakhalin- Kuril Region and overestimated for the southern part of the continental coast of the Sea of Okhotsk.
