is a unique freshwater fish and mainly distributed in the upper stream of Yangtze River and its tributary. In this study, the complete mitochondrial genome of was first determined. The total length of the complete mitochondrial genome is 16,622 bp, contained 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, one D-loop locus, and an origin of replication on the light-strand (OL). The overall nucleotide composition was 31.19% A, 24.84% T, 27.79% C, 16.18% G, with 56.03% AT, respectively. Phylogenetic analysis both highly supported that showed a close relationship with and . These data would contribute to elucidate the evolutionary mechanisms and biogeography of and is useful for the conservation of genetics and stock evaluation for .
是一种独特的淡水鱼，主要分布在长江上游及其支流。在本研究中，首次测定了的完整线粒体基因组。完整线粒体基因组全长16622bp，包含13个蛋白质编码基因（PCGs）、2个rRNA基因、22个tRNA基因、一个D环区域和轻链上的一个复制起点（OL）。总体核苷酸组成为A占31.19%、T占24.84%、C占27.79%、G占16.18%，AT含量分别为56.03%。系统发育分析均高度支持与和显示出密切关系。这些数据将有助于阐明的进化机制和生物地理学，并且对的遗传保护和种群评估有用。
