Аннотация: The subject of the work was an analysis of the contemporary phylogeography of the species and consideration of possible scenarios for sockeye salmon microevolution in the Asian part of the range using the mtDNA control region (D-loop) sequencing. Our data allow us to consider a hypothetical scenario of the formation of the modern sockeye salmon D-loop variability, according to which hap_2 was formed or preserved during the period of the Würm (or Wisconsin) glaciation in a vast paleobasin, a deep-water lake in the Kamakovskaya depression, that existed at that time in the middle course of the Kamchatka River, and was uncovered by ice in the late Pleistocene (Bugaev, Kirichenko, 2008). In addition, refugiums in Asia could located in the basin of Anadyr River, as well as in some parts of the northern coast of the Sea of Okhotsk (Chereshnev, 1998). More southern areas: Sakhalin, Primorye and Hokkaido, were practically not exposed to glaciers (Chereshnev, 1998). We assume that the colonization of the Kuril Islands came from Hokkaido by the carriers of hap_1 haplotype, which, in our opinion, is more ancient and preserved in the southern regions from the first wave of settlement of this species in Asia in the middle Pleistocene.
