Abstract
In this study, the total mitochondrial genome of Sarcocheilichthys sinensis sinensis (Cypriniformes: Cyprinidae) was firstly determined. The genome is 16,683 bases in length. It consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 2 non-coding regions. The overall nucleotide composition of the H-strand of S. sinensis sinensis mitochondrial genome is A: 30.48%, G: 16.65%, T: 26.30% and C: 26.58%, respectively, with an A + T rich feature (56.78%). These results provide useful data to further study of the molecular systematics, species identification and conservation genetics.
