Abstract
Osteochilus salsburyi (Cypriniformes, Cyprinidae) is a small-sized fish of significant economic value. In this paper, the complete mitogenome sequence of O. salsburyi was first determined. It is 16,599 bp in length and consists of a typical vertebrate genome structure including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA (tRNA) genes, and a control region. Except for eight tRNA and ND6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base composition of the heavy strand in descending order is A (33.0%), T (26.5%), C (25.4%), and G (15.0%), with a slight AT bias of 59.5%. This information of O. salsburyi mitogenome could contribute not only to the development of efficient conservation strategy on vulnerable genetic diversity but also to the identification of useful genetic markers for distinction across species boundary.
