Fenneropenaeus penicillatus is a widely distributed economically and ecologically important shrimp species, which is endangered in China. Sequence analysis of 16s rRNA and control region (CR) fragments from mitochondrial DNA was conducted to obtain information on genetic diversity and population structure. Individuals from 12 wild F. penicillatus populations located along the southeast coast of China were used. Polymerase chain reaction (PCR) fragments of the CR gene revealed high genetic diversity among the 12 populations; however, PCR fragments of the 16s rRNA gene revealed very low genetic diversity in the Hainan (HN) and Ningde (ND) populations and high genetic diversity in the DS, BH, PT, XM, and SZ populations. Data obtained from the CR and 16s rRNA genes suggested that high genetic differentiation exists among the 12 populations, which is mainly due to the high genetic differentiation between HN and all other 11 populations. These results may be useful for further sustainable management and utilization of this species.
长毛对虾是一种分布广泛、具有重要经济和生态意义的虾类物种，在中国已濒临灭绝。对线粒体DNA的16s rRNA和控制区（CR）片段进行序列分析，以获取有关遗传多样性和种群结构的信息。研究使用了来自中国东南沿海12个野生长毛对虾种群的个体。CR基因的聚合酶链反应（PCR）片段显示12个种群间具有较高的遗传多样性；然而，16s rRNA基因的PCR片段显示海南（HN）和宁德（ND）种群的遗传多样性非常低，而东山（DS）、北海（BH）、莆田（PT）、厦门（XM）和深圳（SZ）种群的遗传多样性较高。从CR和16s rRNA基因获得的数据表明，12个种群间存在高度的遗传分化，这主要是由于HN与其他11个种群之间的高度遗传分化所致。这些结果可能有助于该物种的进一步可持续管理和利用。
