Abstract

Abstract: Sinocyclocheilus oxycephalus is a freshwater cyprinid fish of high nutritional value, endemic to Shilin County, Southwestern China. In this study, we first sequenced the complete mitochondrial genome (mitogenome) of S. oxycephalus . The whole length of mitogenome is 16, 585 bp, which contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a control region. The gene arrangement and structure is identical to other previously reported Sinocyclocheilus fishes. The overall base composition is 31.26% A, 16.42% G, 25.41% T and 26.90% C, with AT content of 56.67%. Phylogenetic analysis using mitogenomes of 13 cyprinid fishes showed that S. oxycephalus are closely related to S. anophthalmus, S. grahami, and S. wumengshanensis, and 11 Sinocyclocheilus species are grouped as a monophyletic clade with strong supports.
