Abstract
In this study, the complete mitogenome sequence of cyprinid fish, Hainan gudgeon Sarcocheilichthys hainanensis Nichols & Pope, 1927 (Cypriniformes: Cyprinidae) has been amplified and sequenced by employing long polymerase chain reaction method. The mitogenome, consisting of 16,674 base pairs (bp), had the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and a noncoding control region (CR). CR of 1004 bp length is located between tRNAPro and tRNAPhe. The overall base composition of S. hainanensis is 30.0% for A, 26.7% for C, 26.4% for T and 16.8% for G, with a slight AT bias of 56.4%. The complete mitogenome may provide rather essential and important DNA molecular data for further phylogenetic analysis for not only congeneric species but also higher different taxa of cyprinid fishes.
