is a small catadromous fish and has been listed as a second class state protected aquatic animal since 1988 in China due to the declines in its abundance. We describe the complete mitogenome of in this study. The mitogenome is 16,536 nucleotides long and contains 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes, and two main non-coding regions. The overall base composition includes C (30%), A (26.3%), T (25.5%), and G (18.2%). Moreover, the 13 PCGs encode 3800 amino acids in total, all the PCGs use the initiation codon ATG except COI uses GTG. Most of them have TAA or TAG as the stop codon, except COII, ND4 and Cytb use an incomplete stop codon T. The phylogenetic tree based on the neighbour joining method was constructed to provide relationship within Cottidae, which could be a useful basis for management of this species.
是一种小型降海产卵鱼类，由于其数量减少，自1988年以来在中国被列为国家二级保护水生动物。在本研究中，我们描述了的完整线粒体基因组。该线粒体基因组长度为16536个核苷酸，包含13个蛋白质编码基因（PCGs）、两个核糖体RNA基因、22个转运RNA基因和两个主要非编码区。总体碱基组成为C（30%）、A（26.3%）、T（25.5%）和G（18.2%）。此外，13个PCGs总共编码3800个氨基酸，除COI使用GTG外，所有PCGs均使用起始密码子ATG。它们大多数以TAA或TAG作为终止密码子，除COII、ND4和Cytb使用不完全终止密码子T。基于邻接法构建了系统发育树，以提供杜父鱼科内部的关系，这可为该物种的管理提供有用的依据。
