口虾蛄Oratosquilla oratoria是西太平洋重要的生态和经济物种。本研究利用线粒体DNA控制区序列分析了黄海和东海口虾蛄种群的遗传结构。共收集了18个地点的394个样本，获得了102个单倍型。黄海的总体核苷酸多样性和单倍型多样性分别为0.006 9和0.946 8，而东海的总体核苷酸多样性和单倍型多样性分别为0.027 94和0.979 0。AMOVA和成对FST分析结果显示，黄海和东海的黄、东海群体间存在中等分化（0.1452，P0.001）。清唱剧。然而，无论是邻接树还是单倍型网络，均未显示出具有地理格局的分支，这表明黄海和东海之间存在着相当大的基因流，支持了该物种较高的幼虫扩散能力。错配分布分析和中性检验表明，O. oratoria经历了种群扩张事件，更新世冰期旋回可能对O.清唱剧。本研究获得的遗传信息可为捕捞渔业管理策略的可持续改进提供有用的信息。
The mantis shrimp Oratosquilla oratoria is an ecologically and economically important species in the Western Pacific. In present study, the population genetic structure of Oratosquilla oratoria from the Yellow Sea and East China Sea was examined with mitochondrial DNA control region sequences. In total, 394 samples were collected from 18 locations and 102 haplotypes were obtained. For the Yellow Sea, the overall nucleotide diversity and haplotype diversity were 0.006 9 and 0.946 8, respectively; while across all the East China Sea locations, the overall nucleotide diversity and haplotype diversity were 0.027 94 and 0.979 0, respectively. The results of AMOVA and pairwise FST (0.145 2, P <0.001) revealed moderate differentiation between the Yellow Sea and East China Sea populations of O. oratoria. However, neither the neighbor-joining tree nor haplotype network showed clades with geographic pattern, which indicated considerable gene flow was existed between the Yellow Sea and East China Sea, and supporting the high larval dispersal ability in this species. Mismatch distribution analysis and neutrality tests suggested that O. oratoria has undergone population expansion event, and the Pleistocene glacial cycles might have an impact on the historical demography of O. oratoria. The genetic information obtained in this study can provide useful information for sustainable improvements for capture fisheries management strategies.
