Resumo
The suggestion that the fish specimens caught in the littoral zone off Nedorazumeniya Island, Taui Bay, Sea of Okhotsk, belong to the eelpout species Magadanichthys skopetsi [23] and Hadropareia middendorffii Schmidt, 1904 has been confirmed by the analysis of their molecular-genetic and morphological characters. Their karyotypes have been studied for the first time: M. skopetsi, 2n = 48 (2 meta-, 26 subtelo-, and 20 acrocentric chromosomes), NF = 50; H. middendorffii, 2n = 48 (2 meta-, 36 subtelo-, and 10 acrocentric chromosomes), NF = 50. As a result of a comprehensive study, the levels of interspecific differentiation of these species has been established, the degree of intraspecific variability has been determined, and the lack of the population-geographical subdivision of H. middendorffii has been shown.
