Mitochondrial DNA A DNA Mapp Seq Anal. 2018 Aug;29(6):856-861. doi: 10.1080/24701394.2017.1373108. Epub 2017 Sep 8.
Along the coast of Shandong Province in China, an extensive hatchery-release programme has been conducted for more than 10 years. However, no information has been reported concerning the long-term effects on the wild population resulting from the release of large numbers of juveniles in Portunus trituberculatus. In this study, sequence variation of swimming crab P. trituberculatus based on the mitochondrial control region was investigated for 946 swimming crabs at the releasing sites from 2012 to 2014. The result showed that the wild P. trituberculatus was characterized by high genetic diversity indices, and not significantly different from the previous study. Low F values were estimated among the groups of different years and different sites, which suggested no genetic differentiation found in the wild population after the stock enhancement programme. Hence, the long-term extensive hatchery release programme has not affected the genetic structure of wild P. trituberculatus populations along the coast of Shandong Province.
在中国山东省沿海，一项大规模的放流计划已经实施了10多年。然而，关于大量三疣梭子蟹幼体放流对野生种群的长期影响，尚无相关报道。在本研究中，对2012年至2014年放流地点的946只三疣梭子蟹，基于线粒体控制区进行了序列变异研究。结果表明，野生三疣梭子蟹具有较高的遗传多样性指数，与之前的研究无显著差异。不同年份和不同地点的群体间F值较低，这表明在增殖放流计划后，野生种群中未发现遗传分化。因此，长期的大规模放流计划并未影响山东省沿海野生三疣梭子蟹种群的遗传结构。
