The complete mitochondrial genome of Clarias fuscus (Teleostei, Siluriformes: Clariidae)

Abstract

The Clarias fuscus is an important economic fish in China and distributed widely in south China, e.g. Yangtze river, Pearl River, and Min River, even Hainan island. It is also distributed in Southeast Asia and Africa, so it is a good model for study population genetics and geological changes of these region. In this study, the complete mitochondrial genome sequence of C. fuscus has been obtained with PCR. The gene composition and arrangement of mitochondrial genome sequence of C. fuscus are similar to most of other vertebrates, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a non-coding control region with total length of 16,518 bp. Most of genes are encoded on Heavy-Strand (H-strand), except for eight tRNA and ND6 genes. Like most vertebrates, the bias of G and C has universality in different region (genes). The complete mitochondrial genome sequence of C. fuscus would contribute for better understanding of population genetics, conservation, biogeography, evolution of this species.
