“…Literature and our results (Bachevskaya et al, 2013(Bachevskaya et al, , 2015Brykov et al, 2005;Khrustaleva, 2016) Haplotypes of both haplogroups are found in approximately the same proportion in Lake Azabachye, located in the lower reach of the Kamchatka River, as in other river basins of the Asian coast. It can be assumed that the lower parts of the Kamchatka River were inhabited by fish from other refugia during their expansion after the glacier retreat in the Late Quaternary.…”

“…In addition, it is haploid and characterized by a maternal inheritance (Avise, 2004;Park & Moran, 1994) thus non-recombining mtDNA haplotypes can be linked to each other by a network of sequential evolutionary transformations (Bandelt, Forster, & Röhl, 1999). There are only few papers dedicated to sockeye salmon mtDNA geographical variability in both Pacific Ocean coasts (Bachevskaya, Pereverzeva, & Ivanova, 2013;Bachevskaya et al, 2015;Bickham et al, 1995;Brykov et al, 2005;Churikov et al, 2001;Khrustaleva, 2016;Kondzela & Gharrett, 2007), and they cover just some fragmental areas of sockeye salmon range.…”

Analysis of the contemporary geographic distributions of mtDNA haplotypic diversity of sockeye salmon (Oncorhynchus nerka Walbaum) on the Asian part of its range and consideration of possible scenarios for microevolution of the species were performed. In total, 172 specimens of sockeye salmon from different rivers of Kamchatka, Chukotka, north coast of the Sea of Okhotsk, and from the Kuril Islands were analyzed using the entire mtDNA control region (1,010 bp) sequencing. After multiple alignments of the sequences 16 polymorphic sites were identified. Most of substitutions were detected in the first and the last thirds of the D‐loop sequence, as well as one insertion was registered in the poly‐T region. Two mass haplotypes (Hap_1_10T and Hap_2_13T) were revealed; they were present in most samples and differed by three substitutions and two indels. All the sequence variants were distributed among two haplogroups in compliance with the mass haplotypes. The star‐shaped topology of the MST‐tree points to a rapid increase in the diversity of groups, indicating a rapid expansion of the species after its number reducing in the past. The diversity of the first haplogroup was higher, but its main fraction fell on the samples from the middle reach of Kamchatka River, which seems to be a refugium during the Late Pleistocene glaciation. Presence of both haplogroups in most populations in approximately equal proportions indicates that the entire Asian part of the sockeye salmon range is a zone of secondary contact. We hypothesize that Hap_2_13T had more ancient origin and the Hap_1_10T was formed somewhat later, apparently in Asia, because almost all transitional forms between the haplogroups were found in Iturup Island populations.

The analysis of variation of indicators of morphological diversity of three odd generations in the largest North-Okhotsk population of pink salmon of the Ola river (Tauy Bay) is carried out. The variation of morphological diversity in the samples collected from the beginning to the end of the spawning course in the Ola river has a two-vertex character — starting from the first sample to the next one, there is an increase in values, however, in the mid-spawning course, there is a decline, then again some growth. The reason for the detected variation in the indicator of marine diversity is the presence of two races in the population of the pink salmon of the Ola river — early and late. The linear diversity of male pink salmon according to the combined data for all years of research (µ = 18,52 ± 0,329) was higher than that of females (µ = 12,42 ± 0.269) (t = 14,49, p < 0,05). The weight diversity of males was also significantly higher (µ = 16,98 ± 0,330) than in females (µ = 11,14 ± 0,241), (t = 16,69, p < 0,05). The marked differences in the indicators of morphological diversity between females and males can be explained in the framework of the evolutionary theory of sex V. Geodakian. Artificial breeding of pink salmon at a fish breeding plant can have a significant impact on the morphological diversity of a mixed population.
