Antarctic Toothfish are black to olive brown in colour, sometimes lighter on the undersides, with a mottled pattern on body and fins. They have a broad head and an elongated body. They typically move slowly but are capable of speed bursts.
The Antarctic Toothfish lives in sub-zero degree waters, at depths varying between 200m to 2200m, and is caught in the icy Ross Sea, south of New Zealand.
The Ross Sea Antarctic Toothfish fishery is regulated and overseen by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). CCAMLR, an international treaty between 25 nations including New Zealand, imposes stringent environmental protection and by-catch mitigation measures to the fisheries. In addition, the fishery has been certified as sustainable by the Marine Stewardship Council (MSC).
