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.
