Mitochondrial DNA (mtDNA) variation was studied using restriction fragment length polymorphism (RFLP) in chum salmon populations from three rivers in southern Primorye and one river in Sakhalin Island. Significant differences were detected between the samples from Primorye and Sakhalin Island. No differences were found between the samples from the rivers of Primorye, which can be explained by a high rate of gene flow due to transplantation of spawn from one river to another. The effect of fish breeding on the chum salmon populations correlated with the indices of haplotype and nucleotide diversity (h and pi, respectively). The lowest diversity was found in the completely artificial population from the Ryazanovka River; the highest, in natural populations from the Narva and Naiba rivers. Frequencies of haplotypes in consecutive generations were significantly different, which confirms the effects of genetic drift on the small-size chum salmon populations of Primorye.
利用限制性片段长度多态性（RFLP）技术，对来自滨海边疆区南部三条河流及萨哈林岛一条河流的秋鲑种群的线粒体DNA（mtDNA）变异进行了研究。在来自滨海边疆区和萨哈林岛的样本之间检测到显著差异。在滨海边疆区各河流的样本之间未发现差异，这可以用因将鱼卵从一条河流移植到另一条河流而导致的高基因流率来解释。鱼类养殖对秋鲑种群的影响与单倍型指数和核苷酸多样性指数（分别为h和pi）相关。在梁赞诺夫卡河的完全人工种群中发现的多样性最低；在纳尔瓦河和奈伊巴河的自然种群中发现的多样性最高。连续几代单倍型频率存在显著差异，这证实了遗传漂变对滨海边疆区小型秋鲑种群的影响。
