The redfish species (genus Sebastes) are widely distributed across the North Atlantic and adjacent seas of the Arctic Ocean. It is also known that redfish sporadically occur in the White Sea as by-catches in targeted fisheries. However, to date, the information about species affinity, biology and ecology of the White Sea redfish is scarce and contradictory. Some researchers argued that redfish sporadically captured in the White Sea might belong to both Sebastes viviparus and Sebastes norvegicus. In this paper, we presented for the first time genetic analysis and new biological data of the White Sea redfish. We studied nucleotide sequences of the mitochondrial control region (D-loop) and the second intron of the nuclear S7 ribosomal protein gene (RP2 S7) to clarify their species affinity. Results clearly demonstrate that the White Sea redfish belongs to S. norvegicus.

白海金红鱼（Sebastes norvegicus）的分子鉴定

红鱼物种（Sebastes 属）广泛分布于北大西洋和北冰洋附近海域。众所周知，红鱼偶尔会出现在白海，作为目标渔业的副渔获物。然而，迄今为止，关于白海红鱼的物种亲和力、生物学和生态学的信息是稀缺和矛盾的。一些研究人员认为，在白海中零星捕获的红鱼可能属于 Sebastes viviparus 和 Sebastes norvegicus。在本文中，我们首次介绍了白海红鱼的遗传分析和新的生物学数据。我们研究了线粒体控制区 (D-loop) 和核 S7 核糖体蛋白基因 (RP2 S7) 的第二个内含子的核苷酸序列，以阐明它们的物种亲和力。
