Abstract
Salanx cuvieri, a salangid species endemic to China, is mainly distributed in the coastal waters in South China. In this study, we have studied the complete mitochondrial genome of the S. cuvieri. The results show that the complete mtDNA of S. cuvieri is 16,588 bp in length, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes (12S rRNA and 16S rRNA), and 1 control region (CR). The base composition of the genome is 25.3% A, 24% T, 18.2% G, and 32.1% C. Most of the genes are existed in the H-strand, except for the ND6 and other 9 tRNA genes which are encoded on L-strand. A recent study on S. cuvieri has revealed that significant genetic differentiations are found among populations inhabiting different estuaries, so our result can contribute to the preservation of this endangered species.
