Comparative analysis of acclimatization of even and odd broodlines of pink salmon Oncoirhynchus gorbuscha in the White Sea basin according to morphology and population genetics data // The study, sustainable use and conservation of natural resources od the White sea.

Odd-year broodline of pink salmon was successfully introduced into the White Sea basin in 1985, and then even-year pink salmon was carried in 1998. То study the process of acclimatization of both broodlines of pink salmon, we analyzed the variation of several genetic markers (allozyme and microsatellite nuclear loci, and mtDNA), morphological and some biological features in two consecutive generations of odd and even pink in new area and parental population from Magadan oblast (Sea of Okhotsk). In acclimatized odd-year line after eight-nine generations in new area considerable shifts in population genetic structure, external morphology, reproductive features and life cycle were found. Genetic differences between pink salmon in several rivers of the White and Barents Sea and similarity of two generations in Umba River showed first evidence of geographic differentiation and homing ability of successful reproduction of odd-year pink, which indicates adaptation to new environment. We did not find any changes in genetic in even-year line, moreover decrease in number testifies to the lack of adaptation. As in prevoius works on pink salmon acclimatization the success was observed more often for odd-year line, we suggest unequal adaptive ability of two broodlines of pink salmon.
