Hemisalanx brachyrostralis belonging to the family Salangidae is endemic to the Yangtze River. This species has been listed on the Chinese Red List because of the serious decrease in its resources. In this study, we analyzed the complete mtDNA (16588 bp long) of H. brachyrostralis. Overall base composition of the genome is 25.1% A, 25.4% T, 18.7% G, and 30.8% C. The complete mtDNA contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes (12S rRNA and 16S rRNA), and 1 control region. Apart from the ND6 gene and nine tRNA genes encoded on the L-strand, most of the genes are on the H-strand. H. brachyrostralis has the lowest genetic diversity among the Salangid species, so further studies on conservation genetics must be conducted.
短吻间银鱼隶属于银鱼科，为长江流域特有物种。由于其资源量严重下降，该物种已被列入中国红色名录。在本研究中，我们分析了短吻间银鱼的完整线粒体DNA（长度为16588 bp）。基因组的总体碱基组成为：A占25.1%、T占25.4%、G占18.7%、C占30.8%。完整的线粒体DNA包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因（12S rRNA和16S rRNA）以及1个控制区。除了ND6基因和9个在轻链上编码的tRNA基因外，大多数基因位于重链上。短吻间银鱼在银鱼物种中的遗传多样性最低，因此必须进一步开展保护遗传学研究。
