Lutjanus erythropterus is native to (and reared in) the Indo-Pacific region from northern Australia to the Gulf of Oman and to the south of Japan. The species of the family Lutjanidae (snappers) inhabits reefs at depths of 1-300 m. It is mainly caught by commercial, artisanal, and recreational fishery, but despite its slow growth, cage culture is performed. For L. erythropterus to increase its FishEthoScore, more research is needed on the biology and on natural conditions of home range, depth, migration, reproduction, aggregation, aggression, substrate, as well as on farming conditions, stress, and stunning.
