The bigeye scad (Selar crumenophthalmus) is a widely distributed pelagic fish species with highly commercial values. Little information was available about its genetic characteristics. In the present study, we determined the complete mitochondrial genome of S. crumenophthalmus by combining sequences of overlapped fragments amplified by PCR using primers designed for Carangidae species. The entire sequence was 16,610 bp in length, which included a standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions (the control region and the origin of light strand replication). The genome was composed of 27.2% A, 29.5% C, 26.5% T and 16.8% G, showing an obvious anti G bias commonly observed in teleosts. The complete mitogenome sequence of S. crumenophthalmus could contribute for the studies on phylogenetics, population structure and for developing fisheries management strategies.
