The northern mauxia shrimp (Acetes chinensis) is a widely distributed species, and is the main food for many fish of economic importance and other marine organisms. Unfortunately, research on the genetic diversity and differentiation of the A. chinensis population is lacking. We investigated the population genetic structure and genetic diversity of A. chinensis in the East China Sea using the mitochondrial DNA cytochrome c oxidase I (COI) gene. Low overall haplotype diversity, but moderate overall nucleotide diversity, was found compared with other shrimp species. The results also demonstrated that there were two different groups in this region. The patterns of population demography suggest that both Lineages I and II experienced sudden expansions. The findings of this study provide basic information for the protection and management of A. chinensis in the East China Sea.

东海醋栗种群遗传结构及遗传多样性

北毛夏虾（Acetes chinensis）是一种分布广泛的物种，是许多具有重要经济意义的鱼类和其他海洋生物的主要食物。遗憾的是，目前缺乏对中华鳖种群遗传多样性和分化的研究。我们使用线粒体 DNA 细胞色素 c 氧化酶 I (COI) 基因研究了东海中华鳖种群遗传结构和遗传多样性。与其他虾物种相比，发现整体单倍型多样性较低，但总体核苷酸多样性中等。结果还表明，该地区存在两个不同的群体。人口统计模式表明，世系 I 和 II 都经历了突然的扩张。本研究结果为A.的保护和管理提供了基础信息。
