Speciation and diversity of deep-sea fishes from the Sea of Japan were surveyed taxonomically and phylogenetically. During 2001-2003 many specimens were collected from the bottom of Sea of Japan and adjacent waters by cooperation of the Fisheries Research Agency and other institutes in Japan. At least 226 species were listed from the Sea of Japan after examination of both museum collections including the above new materials and literature records ; the 83 species lack voucher specimens (captured records only) and a further search for them is needed. The most diversified taxon was the Zoarcidae, showing 26 species of 8 genera. Molecular data of the Zoarcidae, Cottoidei and Elasmobranchii from the Sea of Japan were also collected. Molecular phylogeny of the Zoarcidae on the basis of mitochondrial DNA (cytochrome b region) suggested that the speciation may be related with geographical history of the sea. Taxonomic research revealed a rare and a probable undescribed species of Zoarcidae, rare species of the Liparidae and Callanthidae from the Sea of Japan.

从分类学和系统发育学角度对日本海深海鱼类的物种和多样性进行了调查。 2001年至2003年期间，日本水产研究机构和其他机构合作，从日本海底部及邻近海域采集了许多标本。经过对两个博物馆藏品（包括上述新材料和文献记录）的检查，至少列出了来自日本海的226种物种； 83个物种缺乏凭证标本（仅捕获记录），需要进一步搜寻。最多样化的分类单元是 Zoarcidae，有 8 属 26 种。还收集了来自日本海的 Zoarcidae、Cottoidei 和 Elasmobranchii 的分子数据。基于线粒体 DNA（细胞色素 b 区）的 Zoarcidae 分子系统发育表明，其物种形成可能与海洋地理历史有关。分类学研究揭示了一种罕见且可能未被描述的 Zoarcidae 物种，来自日本海的 Liparidae 和 Callanthidae 的稀有物种。
