Complete mitochondrial genome of the Asian freshwater goby Synechogobius ommaturus (Perciformes, Gobioidei).

The Asian freshwater goby, Synechogobius ommaturus (Perciformes, Gobiidae) is a big goby inhabiting shallow sandy-muddy bottoms in temperate riverine estuaries and inner bays, mainly distributed in China, Japan, and the Korean Peninsula. In this paper, the complete mitochondrial genome of S. ommaturus was firstly determined. The genome is 16,660 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and 2 main non-coding regions (the control region and the origin of the light strand replication). The overall base composition of S. ommaturus is 26.9% for T, 27.9% for C, 27.7% for A, and 17.4% for G, with a slight A+T bias of 54.6%. It has the typical vertebrate mitochondrial gene arrangement.
