The complete mitochondrial genome of Acanthogobius stigmothonus (Perciformes, Gobiidae).

The complete mitochondrial genome of Acanthogobius stigmothonus is first sequenced in this study. This genome was 16,666 bp in size and contained 37 classic genes, including 13 protein-coding genes, 22 transfer RNA genes and two ribosomal RNA genes. The gene organization and nucleotide composition were the same with those found in most other Gobiidae fishes. Among 37 genes, 28 were encoded by the heavy strand, while nine were encoded by the light strand. The total nucleotide composition of this genome was 27.4% for adenine (A), 17.6% for guanine (G), 28.2% for cytosine (C), and 26.8% for thymine (T), with a high A + T content of 54.2%. This study will provide a better understanding of population genetic diversity of A. stigmothonus and offer useful information for future studies concerning Gobiidae mitogenome evolution.
