本文描述了印度-西太平洋地区重要的经济和生态物种——黄海和东海的剑对虾（Parapenaeopsis hardwickii, Miers, 1878）种群的遗传结构。基于部分mtDNA COI基因，从7个地点采集的130份样本中识别出27个COI单倍型。黄海和东海种群的核苷酸和单倍型多样性分别为0.00187 +/- 0.00021和0.818 +/- 0.049,0.00215 +/- 0.00023和0.822 +/- 0.042。AMOVA和成对FST显示群体间没有明显的遗传分化。贝叶斯推理树和单倍型网络都没有揭示出具有地理模式的进化枝，这表明各海洋对虾种群之间的基因流动水平很高。不匹配分布和中性测试表明，P. hardwickii的历史种群扩张，更新世冰川旋回可能影响了该物种的历史人口统计。本研究为黄海和东海哈氏贝的可持续改良和渔业管理提供了背景资料。
The genetic structure of the populations of the sword prawn Parapenaeopsis hardwickii (Miers, 1878) in the Yellow Sea and East China Sea, an economically and ecologically important species in the Indo-West Pacific region, is described. Based on partial mtDNA COI gene, 27 COI haplotypes are recognized from 130 samples collected from seven locations. Nucleotide and haplotype diversities of the Yellow Sea and East China Sea populations were 0.00187 +/- 0.00021 and 0.818 +/- 0.049, and 0.00215 +/- 0.00023 and 0.822 +/- 0.042, respectively. AMOVA and pairwise FST reveal no significant genetic differentiation of the populations. Neither the Bayesian inference tree nor haplotype network reveals clades with geographic pattern, indicating high levels of gene flow between prawn populations of each sea. Mismatch distribution and neutrality tests suggest an historical population expansion of P. hardwickii, with Pleistocene glacial cycles likely having impacted this species' historical demography. This study provides background information for sustainable improvement and fisheries management of P. hardwickii in the Yellow Sea and East China Sea.
