is a large marine pelagic predatory fish species in the global warm temperate ocean, which is mainly distributed near the offshore rocks and reefs of the Bohai Sea and Yellow Sea of China. In recent years, most research has focused on its breeding and breeding technology at home and abroad, whereas few studies have been conducted on its genome and group composition. The complete mitochondrial DNA was extracted from the somatic side muscles of was obtained using second generation sequencing and splicing with software of DNAStar. The sequence length was 16609 bp, and the base composition was A (26.68%), G (17.84%), C (30.12%), and T (25.36%). It contained 13 protein-coding genes, 22 tRNA genes and 2 rRNA genes. Except for , all the other genes were encoded on the heavy strand (H strand). The A+T content of the complete mitochondrial genome sequence and protein-coding genes were 52.05% and 51.085%, respectively. There was a strong bias toward A+T in the genome of . There were two repeated sequences scattered in the genes. One was located in the middle part of the sense strand of the gene sequence, and the other was located in the upper part of the antisense strand of gene sequence. All tRNA genes had typical cloverleaf structure except tRNA^Gly. Its start-stop sites and codons of protein-coding genes, except , which inhabits in the oceans of Japan. The were shorter than those of . It was preliminarily assumed that there were genetic differences between . The NJ-tree based on the complete mitochondrial DNA genomes showed the evolutionary position of relative to that of 18 other Carangidae species. The results showed that the . Furthermore, had a closer relationship than others in the tree, whereas S. nigrofasciata. This study provides basic data for solving different geographical population and kinship relations of .
