Abstract

In this study, the mitochondrial genome was sequenced in a new commercial species, spotted knifejaw (O. punctatus), using next-generation sequencing and PCR-based methods. The overall length of the female O. punctatus mitochondrial genome was 16,508 bp. It contained 13 PCGs, 2 r-RNA genes, 22 t-RNA genes, and a displacement loop locus (a control region). The total nucleotide composition was 28.75% A, 25.69% T, 29.70% C, and 15.86% G, with a total A + T content of 54.44%. The results demonstrated that the mitochondrial genome of O. punctatus has a high sequence identity with that of another species of Perciformes. This finding provides a deeper understanding of mitogenomic diversity and evolution in marine fish.
