Short description

Dorsal spines (total): 1; Dorsal soft rays (total): 48-57; Anal spines: 0; Anal soft rays: 40 - 46; Vertebrae: 53 - 58. Body more slender than other hakes. Pectoral fins long and slender, stripe reaching anal fin in young individuals but not in fish over 50 cm in SL. Gill rakers short and thick with blunt tips. Color is steel gray on back grading to silvery white ventrally.

Found at depths between 415 and 1000 m in New Zealand waters, and 62 to 800 m in South American waters. The Patagonian population feeds on southern blue whiting, whiptail, nototheniids and squids. The New Zealand population feeds mainly on fishes (especially gadoids), squids, euphausiids and benthic organisms. Adults probably migrate southward during the southern summer for feeding and return to the north in winter for spawning (Ref. 1371). Spawning takes place from August to September on the western coast of South Island, from September to November in the northern part of the Campbell Plateau, and between November and January on Chatham Rise (Ref. 58452). Utilized as food fish and fishmeal.
