Abstract

Schizothorax molesworthi is an endemic species and distributes in the MoTuo reaches of the Yarlung Zangbo River. It is one of the most important commercial fishes in this area. In the present study, the complete mitochondrial DNA sequence of Schizothorax molesworthi was determined and analyzed. The mitochondrial genome of Schizothorax molesworthi is 16,585 bp in length and consisted of 37genes in the typical vertebrate mitochondrial gene arrangement. Overall base composition of mitochondrial genome of Schizothorax molesworthi was 30.1% A, 26.9% C, 17. 4% G, and 25.6% T, with a high A + T content (55.7%). Phylogenetic analysis showed that Schizothorax molesworthi and Schizothorax plagiostomus clustered together in a clade and formed a sister relationship.
