Abstract
The Malabar trevally Carangoides malabaricus is a widely distributed inshore fish species and commercially important in some tropical regions. This study presented the complete mitochondrial genome of C. malabaricus as well as its phylogenetic position in Carangidae. The entire sequence was 16,561 bp in length, including the typical structure of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, 1 control regions and 1 L-strand replication origin. The arrangement of the genes was in line with other teleosts. The genome was composed of 29.6% C, 27.8% A, 26.2% T and 16.4% G, showing an obvious anti G bias. Phylogenetic analyses using the concatenated sequence of the protein-coding genes showed similar results in the Neighbour-Joining and Bayesian inference trees. Three clades were formed as Subfamilies Caranginae, Seriolinae and Trachinotinae in Carangidae based on the current dataset. C. malabaricus was most closely related to the species in the same genus.
