Variability of three PCR-amplified mtDNA regions was examined in five populations of sockeye salmon from Azabach'e Lake. Eighteen haplotypes were detected in 144 fish. Significant differences were found between seasonal races of sockeye salmon spawning in the lake. The short time of independent divergence between the seasonal races indicates that these races formed independently in each spawning region. No difference in mtDNA between lake samples of early sockeye salmon (subisolates) was revealed, which confirms the existence of gene flow between them. A high level of differences between the sockeye salmon spawning in the lake and spawning in the tributaries of the lake, the Bushuev and Lotnaya rivers, suggests that there were no migration between them during many generations and that the nature of spawning grounds (lake or river) is essential for within species differentiation in this species.
对来自阿扎巴赫湖的五个红大麻哈鱼种群的三个聚合酶链反应（PCR）扩增的线粒体DNA（mtDNA）区域的变异性进行了检测。在144条鱼中检测到了18种单倍型。在该湖产卵的红大麻哈鱼季节性种群之间发现了显著差异。季节性种群之间独立分化的时间较短，这表明这些种群是在每个产卵区域独立形成的。未发现早期红大麻哈鱼湖样本（亚分离株）之间的mtDNA差异，这证实了它们之间存在基因流动。在该湖产卵的红大麻哈鱼与在该湖支流布舒耶夫河和洛特尼亚河产卵的红大麻哈鱼之间存在高度差异，这表明它们在许多代中没有迁移，并且产卵地（湖或河）的性质对于该物种的种内分化至关重要。
