Octopuses are an important fishery resource in the Ryukyu Archipelago, Japan, and Octopus cyanea is an important fishery resource in this region. Although a gradual downward trend in catches of O. cyanea in the Ryukyu Archipelago has been reported, no study has focused on the connectivity and genetic structure, which are important parameters for conservation strategies. We used partial sequences of mitochondrial COI and MIG-seq, which can efficiently obtain single nucleotide polymorphism (SNPs) to evaluate genetic diversity and patterns of gene flow among three populations of O. cyanea in the Ryukyu Archipelago. We combined population genetic analyses with biophysical approaches to understand larval dispersal patterns and the regional connectivity. Although there was a tendency for the Yaeyama population to become isolated from the Okinawa-jima populations, high genetic diversity was maintained overall, indicating frequent genetic exchange between populations. Population genetic analyses combined with larval dispersal simulations revealed that the contemporary migration of O. cyanea is asymmetric patterns among the three populations, suggesting that western coast of Okinawa-jima Island functions as a source population among the three populations we examined. The potential implications of this study on the conservation management of O. cyanea were discussed, namely that future population assessment approaches are needed to include western coast of Okinawa-jima populations. In addition, this study indicates that at least two different management units should be considered. This study is the first population genetic study of O. cyanea in the Ryukyu Archipelago and provides fundamental information on the genetic population structure of this species in this region.
八爪鱼是日本琉球群岛的重要渔业资源，而八爪鱼（Octopus cyanea）是该地区的重要渔业资源。虽然有报道称琉球群岛的八爪鱼渔获量呈逐渐下降趋势，但还没有研究重点关注八爪鱼的连通性和遗传结构，而这正是保护战略的重要参数。我们利用线粒体 COI 部分序列和 MIG-seq（可有效获得单核苷酸多态性 (SNP)）评估了琉球群岛 O. cyanea 三个种群之间的遗传多样性和基因流动模式。我们将种群遗传分析与生物物理方法相结合，以了解幼虫扩散模式和区域连通性。虽然八重山种群有与冲绳岛种群隔离的趋势，但总体上保持了较高的遗传多样性，表明种群间的遗传交流频繁。种群遗传分析结合幼虫扩散模拟显示，O. cyanea在三个种群之间的当代迁移模式是不对称的，这表明冲绳岛西海岸在我们研究的三个种群中发挥着源头种群的作用。本研究还讨论了对 O. cyanea 保护管理的潜在影响，即未来的种群评估方法需要包括冲绳岛西海岸种群。此外，本研究还表明至少应考虑两个不同的管理单位。本研究是首次对琉球群岛的 O. cyanea 进行种群遗传研究，为该地区该物种的遗传种群结构提供了基本信息。
