“…Although elasmobranch fish are highly mobile when adults (Gaither, Bowen, Rocha, & Briggs, ), thermal barriers (such as the Tsushima Warm Current) may preclude contemporary gene flow between the mottled skate populations in the East Sea and Yellow Sea. Similar examples of species affected by the biogeographic barrier between the East and Yellow Seas have been reported, including Hemigrapsus sanguineus (Hong et al., ), Pollicipes mitella (Yoon, Jung, & Kim, ), Konosirus punctatus (Myoung & Kim, , ), and Ammodytes personatus (Kim, Lee, Lee, Kim, & Kim, ).…”

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.

“…Myoung & Kim () estimated that the divergence of K. punctatus lineages A and B occurred when the East (Japan) Sea was isolated from the East China Sea during the LGM. Another species, Ammodytes personatus Girard 1856, also showed a significant biogeographic barrier between the East (Japan) Sea and Yellow Sea based on genetic composition and spawning characteristics (Kim et al , , ). In contrast, H. sajori might have gone extinct in the East (Japan) Sea after the separation from the East China Sea during the glacial periods because of its susceptibility to marine environmental changes.…”

This paper presents preliminary data on the genetic diversity and population structure of Hyporhamphus sajori by analysing a 510 bp sequence in the mitochondrial DNA (mtDNA) control region and eight polymorphic microsatellite DNA loci. The H. sajori individuals from different locations were indistinguishable from one another based on mtDNA variation, as demonstrated with a neighbour-joining tree and minimum spanning network analysis. Low level of genetic diversity and the absence of population structure in H. sajori from the north-west Pacific Ocean, combined with negative indices for neutral evolution in these populations, suggest that H. sajori underwent a population expansion after a recent bottleneck. The Structure analysis, discriminant analysis of principal components (DAPC) and the pair-wise Φ values after Bonferroni correction using eight microsatellite loci provided no clear inference on the genetic differentiation and thus no evidence of population structure of H. sajori. The genetic connectivity among locations might be due to fairly high gene flow via transport of eggs and larvae by the Kuroshio and Tsushima warm current. This study revealed low levels of genetic diversity and suggested high level of contemporary gene flow among populations of H. sajori in the East (Japan) Sea and the Pacific Ocean.

“…Kim et al [19] reported that the number of sand lance larvae decreased significantly in the southern East Sea. Therefore, it is possible that interspecific hybridization occurs in preference to assortative mating when there are few individuals from a particular group.…”

“…The number of vertebrae was a good taxonomic characteristic for distinguishing the two lineages: although the numbers partially overlap [ 16 ], 64–67 (modes = 65 and 66) in the NOL from the East Sea, and 62–65 (modes = 62, 63, and 64) in the SOL from the Yellow Sea and the Korean Strait. However, the NOL and SOL could not be regarded as separate species because of the presence of an admixture zone [ 18 ], spawning aggregation [ 19 ], and gene flow between the two lineages [ 20 ].…”

Based on northern (NOL) and southern (SOL) mitochondrial lineages, recently, it proposed the new species Ammodytes heian and revived the species name Ammodytes japonicus to describe sand lances from the northwestern Pacific Ocean. This study used molecular methods to investigate genetic relationships between the two sand lance species in Korea and Japan. In total, 154 specimens were collected from four locations in Korea (Baengnyeongdo in the Yellow Sea, Tongyeong in the Korean Strait, and Jumunjin and Gijang in the East Sea), and 50 specimens were collected from a single location in Japan (Wakkanai in the Okhotsk Sea). Mitochondrial DNA analysis demonstrated that the individuals from Baengnyeongdo and Tongyeong all belonged to the SOL, whereas those from Gijang, Jumunjin, and Wakkanai included individuals from both the NOL and SOL (over 75% NOL). Population structure analyses were performed on the same individuals using seven microsatellite DNA markers. The population structure analysis based on 201 specimens identified two clusters (named as northern group and southern group), with the admixture proportion (q) of < 0.1 for the northern group in the Backyeongdo and Tongyeong sand lances and < 0.1 for the southern group in the Wakkanai sand lances. The high heterogeneity indicated that the former was probably A. japonicus and the latter probably A. heian. However, the admixture proportion in the Jumunjin and Gijang sand lances was 0.71–0.75 for the southern group, indicating that hybridization and unidirectional introgression from SOL to NOL occurs in southwestern margin of the East Sea. Our findings illustrate the speciation process based on different patterns of gene flow between Korean and Japanese sand lance, which is strongly influenced by both the paleo-climatic change and the contemporary local oceanic current pattern.
