Аннотация:The geographical structure and dynamics of introgressive hybridization with Atlantic herringClupea harengus were studied for the Pacific herring Clupea pallasii based on long-term monitoring of geneticvariation of C. pallasii from the White, Barents, and Kara seas using multivariate statistical analysis procedures in the Structure and NewHybrids programs. An unequal level of introgression of the Atlantic herring’sgenes have been reported for the population of the White Sea summer-spawning and spring-spawning herringas well as for the Chesha-Pechora () herring. The factors involved in supporting the hybridization of herringspecies in the zone of their secondary contact were considered. The predominant role of hybridization andintrogression of genes in the formation of intraspecific genetic diversity of the Pacific herring was revealed
