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.

In this study, the complete mitogenome sequence of cyprinid fish, Hainanese barbel steed, Hemibarbus medius Yue (Teleostei: Cyprinidae) has been amplified and sequenced by employing long polymerase chain reaction method. The mitogenome, consisting of 16,614 base pairs (bp), had the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and a non-coding control region (CR). CR of 933 bp length is located between tRNA(Pro) and tRNA(Phe). The overall base composition of Hemibarbus medius is 29.8% for A, 27.2% for C, 25.9% for T and 17.1% for G, with a slight AT bias of 55.7%. 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.
