Osteochilus salsburyi (Cypriniformes, Cyprinidae) is a small-sized fish of significant economic value. In this paper, the complete mitogenome sequence of O. salsburyi was first determined. It is 16,599 bp in length and consists of a typical vertebrate genome structure including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA (tRNA) genes, and a control region. Except for eight tRNA and ND6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base composition of the heavy strand in descending order is A (33.0%), T (26.5%), C (25.4%), and G (15.0%), with a slight AT bias of 59.5%. This information of O. salsburyi mitogenome could contribute not only to the development of efficient conservation strategy on vulnerable genetic diversity but also to the identification of useful genetic markers for distinction across species boundary.
苏氏结鱼（鲤形目，鲤科）是一种具有重要经济价值的小型鱼类。本文首次测定了苏氏结鱼的完整线粒体基因组序列。其长度为16,599 bp，由典型的脊椎动物基因组结构组成，包括13个蛋白质编码基因、2个核糖体RNA基因、22个转移RNA（tRNA）基因和一个控制区。除了8个tRNA和ND6基因外，所有其他线粒体基因都在重链上编码。重链的总体碱基组成由高到低依次为A（33.0%）、T（26.5%）、C（25.4%）和G（15.0%），AT偏倚率为59.5%。苏氏结鱼线粒体基因组的这些信息不仅有助于制定针对脆弱遗传多样性的有效保护策略，还有助于识别跨越物种界限的有用遗传标记。
