Morphology | Morphometrics
Common species (Ref. 34024). Found between depths of 22 m (Ref. 58489) and 1000 m (Ref. 33848). Feed mainly on crustaceans such as Munida and scampi and also on fish. Also caught above the bottom when feeding on hoki (Macruronus novaezelandiae) during the hoki spawning season. Available all year round. Juveniles are found in shallower shelf waters (Ref. 6390). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Utilized fresh, frozen or smoked; can be fried and baked (Ref. 9988, 34024).
