Highighted items on the list are where Hoplostethus atlanticus may be found.
Remarks Found on the continental slope (Ref. 75154). Orange roughy feed opportunistically on bentho-pelagic and meso-pelagic fish, crustaceans, and squid. Juveniles feed mainly on crustaceans whereas adults prefer fish and squids. They appear to have moderately high rates of food consumption (Ref. 27075). Dietary changes may be linked to modifications in morphology with growth (Ref. 27076). Little is known of the larvae and juveniles, which do not appear to aggregate (Ref. 6390).
