Hemibagrus nemurus (Valenciennes, 1840) is a kind of tropical freshwater catfish which is native to Asian waters. It is economically valued for its importance in fisheries and aquaculture. At present, there exist some confusion in species identification in Bagridae. In this paper, we sequenced and characterize the complete mitogenome of H. nemurus. The genome was 16,526 bp in length, and typically consists of 37 genes, including 13 protein-coding genes, 2 rRNAs, 22 tRNA, 1 origin of replication on the light-strand (OL) and a single large control region (CR). The gene organization is identical to that of a typical bony fish. The overall base composition was 31.5%, 26.6%, 26.7%, and 15.2% for A, T, C, and G, respectively, with a slight bias on AT content (58.1%). This result is expected to provide useful molecular data and contribute to further taxonomic and phylogenetic studies of Hemibagrus and Bagridae.
半须鲶（Hemibagrus nemurus，瓦朗谢讷，1840年）是一种热带淡水鲶鱼，原产于亚洲水域。因其在渔业和水产养殖中的重要性而具有经济价值。目前，鲿科鱼类的物种鉴定存在一些混淆。在本文中，我们对半须鲶的完整线粒体基因组进行了测序和特征分析。该基因组长度为16,526 bp，通常由37个基因组成，包括13个蛋白质编码基因、2个rRNA、22个tRNA、1个轻链复制起点（OL）和1个单一的大控制区（CR）。基因组织与典型硬骨鱼相同。A、T、C和G的总体碱基组成分别为31.5%、26.6%、26.7%和15.2%，AT含量略有偏向（58.1%）。这一结果有望提供有用的分子数据，并有助于对半须鲶和鲿科进行进一步的分类学和系统发育研究。
