Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Southeast Pacific and Southwest Atlantic: southern Chile round the coast to Patagonia (Argentina) and the Falkland Islands. Southwest Pacific: Macquarie Island. Southern Ocean: South Georgia. Also known from sub-Antarctic islands and seamounts of the Indian sector.

Biology     Glossary (e.g. epibenthic)

At 12-15 cm TL, semi-pelagic juveniles become demersal at 150-400 m depth (Ref. 55957). Adults migrate to deeper habitats at depths greater than 1,000 m (Ref. 55957). Utilized as food fish (Ref. 4931). The South Georgia Patagonian Toothfish Longline Fishery of this species has been certified by the Marine Stewardship Council (http://www.msc.org/) as well-managed and sustainable (http://www.msc.org/html/content_1062.htm).
