“…This may be attributable to the strong influence of the Tsushima Warm Current in the East Sea, but not in the Yellow Sea. The Yellow Sea mottled skate can live in an extremely low seawater temperature range of 0.7–1.7°C (Antonenko et al., ), and is not detected in waters exceeding 15°C (Jang et al., ), indicating that it is adapted to relatively lower temperatures than the East Sea mottled skate. We infer that these different oceanographic conditions contribute to the local differentiation of the species.…”

“…During the last glacial maximum (LGM), the sea level was 115–130 m lower than at present (Clark et al., ; Ludt & Rocha, ; Shen, Jamandre, Hsu, Tzeng, & Durand, ; Xu & Oda, ) and it is assumed that the habitat of the mottled skate was forced southward, where it was affected by the Kuroshio Warm Current (Xu & Oda, ), thus the species may have become extinct because it is a cold water species (Antonenko et al., ; Jang et al., ). Since the LGM, the sea level has risen, forming the Yellow Sea and opening a connection to the East Sea (Kitamura, ; Shen et al., ).…”

“…The mottled skate, Beringraja pulchra (Rajidae), is a Northwest Pacific species found in waters off Korea, Japan, China, Taiwan, and Russia (Antonenko, Solomatov, Balanov, Kim, & Kalchugin, ; Froese & Pauly, ; Ishihara, Treloar, Bor, Senou, & Jeong, ; Jeong, ; Kim et al., ). The mottled skate was originally classified in the genus Raja , but was reassigned to the new genus Beringraja , established by Ishihara et al.…”

In order to prove the fisheries-related hypothesis of the presence of two local populations of the mottled skate, Beringraja pulchra in the Yellow Sea (Sensu Jo et al., 2011), the geographic variations of 90 individuals (in molecule) and 129 individuals (in morphology) were investigated. The skates were collected from the middle Yellow Sea (Daechungdo), southern Yellow Sea (Heuksando), and the middle East Sea (Ulleungdo) using gill nets, bottom trawls and longlines. Comparing 471 base pairs of mitochondrial DNA cytochrome c oxidase subunit I (mtDNA COI) sequences, only three haplotypes (BR1-BR3) were found. The Daechungdo and Heuksando individuals displayed all three haplotypes, whereas the Ulleungdo individuals displayed a single haplotype (BR3). Pairwise fixation indices (FST) showed that the Daechungdo and Heuksando individuals were not genetically distinguishable (with a value of −0.0344), whereas the Ulleungdo individuals were clearly distinct from both the Daechungdo and Heuksando individuals (with values of 0.6875 and 0.6871, respectively). Similar to the molecular result, a canonical discriminant analysis based on seven morphometric characters showed that the Ulleungdo individuals had positive values on the first axis, whereas those from the other two locations had negative values, slightly differentiating the two populations (East Sea population vs Yellow Sea population). This study is the first to identify two populations of mottled skate in the northwest Pacific.

The mottled skate, Raja pulchra, is an economically valuable fish. However, due to a severe population decline, it is listed as a vulnerable species by the International Union for Conservation of Nature. To analyze its genetic structure and diversity, microsatellite markers were developed using 454 pyrosequencing. A total of 17,033 reads containing dinucleotide microsatellite repeat units (mean, 487 base pairs) were identified from 453,549 reads. Among 32 loci containing more than nine repeat units, 20 primer sets (62%) produced strong PCR products, of which 14 were polymorphic. In an analysis of 60 individuals from two R. pulchra populations, the number of alleles per locus ranged from 1–10, and the mean allelic richness was 4.7. No linkage disequilibrium was found between any pair of loci, indicating that the markers were independent. The Hardy–Weinberg equilibrium test showed significant deviation in two of the 28 single-loci after sequential Bonferroni’s correction. Using 11 primer sets, cross-species amplification was demonstrated in nine related species from four families within two classes. Among the 11 loci amplified from three other Rajidae family species; three loci were polymorphic. A monomorphic locus was amplified in all three Rajidae family species and the Dasyatidae family. Two Rajidae polymorphic loci amplified monomorphic target DNAs in four species belonging to the Carcharhiniformes class, and another was polymorphic in two Carcharhiniformes species.

“…It is one of the largest fishes distributed in the Yellow Sea and the East Sea in the Korean Peninsula, and the Sea of Okhotsk from Japan to the coast of China (Ishihara 1990). Recently, it has been reported that R. pulchra in the Russian waters is found only in the coasts of Western Sakhalin (Antonenko et al 2011). There has been a suggestion that R. pulchra should belong to the genus Beringraja, as they share the unique strategy of laying eggs (Ishihara et al 2012;Chiquillo et al 2014).…”

In this study, the mitogenome of nine Raja pulchra individuals from Yellow Sea (n ¼ 7) and even from Alaska (n ¼ 2) was sequenced, and the genomic variation and phylogeny were examined. The length of the mitogenome was 16,906 and 16,907 bp showing 99.6% sequence similarity with the previously reported sequence. Of the one hundred and fifty-one single nucleotide polymorphisms, sixty-three were newly detected compared to previous studies. They were present in the 16s rRNA gene, 2 tRNA genes, 13 protein-coding genes, and a non-coding region. The mitogenomes and SNPs will provide a better understanding of the ecological genetics of R. pulchra. ARTICLE HISTORY
