The Pacific seabream,
Acanthopagrus pacificus
, is a commercially valuable resource for fisheries around the West Pacific Ocean countries. Although the phylogenetic position of the
A. pacificus
within the genus
Acanthopagrus
changes by the differences in the target gene regions or fish sampling locations, the genetic information of the species is quite limited. In this study, the complete mitochondrial genome of
A. pacificus
from Iriomotejima Island, Okinawa, Japan was determined. The sequence is 16,640 bp in length and consists of 13 protein-coding genes, 2 rRNA genes (12S rRNA and 16S rRNA), 22 tRNA genes, and one control region. A reconstructed phylogenetic tree showed that
A. pacificus
has the furthest relationship to other
Acanthopagrus
species in the genus.
