Fenneropenaeus penicillatus, which is on the Red List of Endangered Species for China, is an important shrimp species. However, there is not enough genetic information on F. penicillatus for conservation and management purposes. Ten microsatellite markers were used to analyze the genetic diversity, genetic differentiation, and population structure of F. penicillatus to provide scientific information for the conservation of the species. Low genetic diversity and moderate genetic differentiation were found among 12 putative populations [Beihai, Dongshan (DS), Hainan (HN), Lianjiang, Nanao (NA), Ningde (ND), Putian, Quanzhou (QZ), Xiamen (XM), Shenzhen, Zhanjiang, and Zhangpu] along the southeast coast of China. QZ, XM, and DS exhibited the highest genetic diversity, while NA and ND had the lowest genetic diversity. Genetic differentiation among all populations, except HN, was low compared to the genetic differentiation between HN and the other 11 putative populations. These 12 putative populations were divided into two subgroups. One group consisted of XM, DS, and QZ. The other group consisted of the other eight putative populations with the exception of HN. The HN Island population requires further study due to its large genetic distance from the other 11 putative populations. Problems with the current conservation strategy are pointed out and suggestions given based on genetic information.
斑节对虾是中国濒危物种红色名录中的重要虾类物种。然而，目前关于斑节对虾的遗传信息不足，难以满足保护和管理的需求。本研究利用10个微卫星标记分析了斑节对虾的遗传多样性、遗传分化和种群结构，为该物种的保护提供科学依据。在中国东南沿海的12个假定种群（北海、东山、海南、连江、南澳、宁德、莆田、泉州、厦门、深圳、湛江和漳浦）中，发现遗传多样性较低，遗传分化程度中等。泉州、厦门和东山的遗传多样性最高，而南澳和宁德的遗传多样性最低。除海南外，所有种群间的遗传分化程度较低，而海南与其他11个假定种群间的遗传分化程度较高。这12个假定种群被分为两个亚组。一组由厦门、东山和泉州组成。另一组由除海南外的其他八个假定种群组成。由于海南种群与其他11个假定种群的遗传距离较大，因此需要进一步研究。基于遗传信息指出了当前保护策略存在的问题并提出了建议。
