is the only species distributed in Bohai Gulf of China. The wild populations of this species have sharply declined in China due to overfishing. Over 150 samples from Bohai Gulf were collected in the present study, which were classified into five populations according to their geographic areas and body colors. The genetic diversity and population structure of these populations were investigated by mitochondiral and D-loop sequences. The haplotype diversity of based on and D-loop sequences were still high. In addition, the evolution rate of D-loop region could faster than the gene of . Meanwhile, over 99% genetic diversity was contributed by different individuals within populations. Moreover, phylogenetic trees did not show clear geographic or color cluster. Our findings indicated that this species in Bohai Gulf of China should be treated as a whole population.
是中国渤海湾唯一分布的物种。由于过度捕捞，该物种在中国的野生种群数量急剧下降。本研究收集了来自渤海湾的150多个样本，根据其地理区域和体色将它们分为五个种群。通过线粒体和D-loop序列研究了这些种群的遗传多样性和种群结构。基于线粒体和D-loop序列的单倍型多样性仍然很高。此外，D-loop区域的进化速率可能比该物种的线粒体基因更快。同时，超过99%的遗传多样性由种群内不同个体贡献。此外，系统发育树没有显示出明显的地理或颜色聚类。我们的研究结果表明，中国渤海湾的该物种应被视为一个整体种群。
