Complete mitochondrial genome of the freshwater gudgeon, Gobiobotia brevibarba (Cypriniformes; Cyprinidae).

The complete mitochondrial genome was sequenced from the freshwater gudgeon, Gobiobotia brevibarba. The genome sequence was 16,595 bp in size, and the gene order and contents were identical with the congeneric G. nakdongensis and G. macrocephala mitochondrial genomes. Of 13 protein-coding genes (PGCs), 3 genes (CO2, CO3 and Cytb) had incomplete stop codons. The base composition of G. brevibarba showed slight anti-G bias (13.79% and 14.15%) on the second and third positions of PCGs.
