Red king crab (Paralithodes camtschaticus) was introduced into the Barents Sea in the 1960-1970s. Its present habitation area spans on the coastal zone from Hammerfest (Northern Norway) to the Barents Sea Funnel in the north-east of the Kola Peninsula. We studied the polymorphism of a mitochondrial gene encoding cytochrome oxidase (COI) and five nuclear microsatellite loci in four samples from the Barents Sea and two donor populations from the Western Kamchatka and Primorye. No decrease in the genetic diversity of the introduced populations was detected. Microsatellite assay demonstrated that the sample from Varrangerfjord was distinct from the rest five populations. However, no significant differences between the rest samples were found. Possible reasons underlying this phenomenon are discussed.
红帝王蟹（堪察加拟石蟹）于20世纪60至70年代被引入巴伦支海。其目前的栖息地范围从哈默菲斯特（挪威北部）的沿海地区一直延伸至科拉半岛东北部的巴伦支海漏斗处。我们研究了来自巴伦支海的四个样本以及来自堪察加半岛西部和滨海边疆区的两个供体种群中编码细胞色素氧化酶（COI）的线粒体基因和五个核微卫星位点的多态性。未检测到引入种群的遗传多样性下降。微卫星分析表明，瓦朗厄尔峡湾的样本与其他五个种群不同。然而，其余样本之间未发现显著差异。本文讨论了这一现象背后的可能原因。
