Liobagrus nigricauda is endemic to the Yangtze River system (Ding 1994, The fishes of Sichuan province. pp. 470-78) and listed as an endangered species (IUCN 2012, Red list of threatened species. ). In this study, the complete mitochondrial genome sequence of L. nigricauda has been obtained with polymerase chain reaction (PCR), which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a noncoding control region with the total length of 16,512 bp. The gene arrangement and composition are similar to that of other vertebrates. Most of the genes are encoded on heavy strand, except for eight tRNA and ND6 genes. Just like most other vertebrates, the bias against G has a universality in different statistics results. The mitogenome sequence of L. nigricauda would contribute to better understand population genetics and to protect its genetic diversity.
