Abstract
Rhinogobio ventralis, a small-sized economic fish living in the bottom of the fast-flowing water, has a limited geographical distribution in the upper reaches of Yangtze River in China. The complete mito-genome of R. ventralis is 16,607 bp in length, containing 37 genes of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a control region (D-loop). The gene order and composition of R. ventralis is similar to that of most other fishes, and its nucleotide composition is 31.10% A, 26.64% T, 26.28% C and 15.98% G, with a slight AT bias of 57.74%. It is first report of the complete mitochondrial genome in the bottom dwelling Rhinogobio species.
