摘要

Genetic deviation between two deep-sea snailfishes, Careproctus pellucidus from the Pacific Ocean and Careproctus rastrinus from the Okhotsk Sea, of the Careproctus rastrinus species complex was analyzed, based on the nucleotide sequences of the mitochondrial cytochrome b (Cytb) gene. Our sampling revealed the occurrence of individuals with C. rastrinus-type Cytb genes off northeastern Japan, in the northwestern Pacific. Most of these individuals were collected from an area off Miyagi Prefecture, while few individuals were collected from areas to its north (off Iwate Prefecture) and south (off Fukushima and Ibaraki Prefectures). Phylogeographic analyses based on nucleotide sequences of the first intron region of the nuclear S7 ribosomal protein gene (S7) and 11 microsatellite loci indicated little genetic deviation between individuals with C. pellucidus-type and C. rastrinus-type Cytb genes in the area off Miyagi Prefecture. Significant genetic differences between the Pacific Ocean and the Okhotsk Sea populations may be attributed to unidirectional migration due to a greater current from the latter to the former. In addition, peritoneum and stomach colors of 10 and 17 specimens collected from the Pacific Ocean and the Okhotsk Sea, respectively, were evaluated quantitatively. The colors were significantly different for the two populations; however, they appeared to overlap. Although only one Pacific individual with a C. rastrinus-type Cytb gene was available for color evaluation, it was more similar to Pacific individuals than to Okhotsk Sea individuals. These results suggest inbreeding between C. pellucidus and C. rastrinus in the Pacific Ocean, off Miyagi Prefecture.

Rastrinus型CytB基因的喀特尔型的个体进行颜色评估，但它比太平洋个人更类似于okhotsk Sea个人。这些结果表明了宫城县太平洋C. Pellucidus和C. Rastrinus之间的繁殖。
