The complete mitochondrial genome of Odontobutis yaluensis was sequenced as to be 16,909 bp in length with (A + T) content of 55.73%, and it contained 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. The gene order and orientation are similar to some typical fish species. The data will provide the useful molecular information for phylogenetic relationships of O. yaluensis with Odontobutis potamophila first clustered into a small branch, and then with Odontobutis platycephala clade, and finally with Odontobutis sinensis clade. Odontobutidae and Rhyacichthyidae formed the sister group, and Eleotridae and Gobiidae formed the sister group.
鸭绿江沙塘鳢的完整线粒体基因组测序结果显示，其长度为16,909 bp，（A+T）含量为55.73%，包含13个蛋白质编码基因、2个rRNA、22个tRNA和一个控制区。基因顺序和方向与一些典型鱼类相似。这些数据将为鸭绿江沙塘鳢的系统发育关系提供有用的分子信息。鸭绿江沙塘鳢首先与河川沙塘鳢聚为一个小分支，然后与平头沙塘鳢分支相聚，最后与中华沙塘鳢分支相聚。塘鳢科和溪鳢科形成姐妹群，弹涂鱼科和虾虎鱼科形成姐妹群。
