Chinese sleeper (Perccottus glenii) belongs to the largest vertebrate order, Perciformes. In this study, the complete mitochondrial genome of P. glenii was determined to be 16,487 bp in length, including 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. We also analysed the sequence structure of non-coding control region. Comparing the mitochondrial genome of P. glenii with its congener Rhyacichthys aspro showed sequence similarity and the identical gene arrangement. The complete mitochondrial genome of Chinese sleeper provides the basis for the studies in Perciformes evolution and conservation.
