Toothfish are caught by longline, trawl and pot, typically in depths of 500-1800m. Patagonian toothfish is caught off the coasts of Chile, Argentina, Peru, Uruguay, Patagonia, and around sub-Antarctic islands and seamounts. Antarctic toothfish is generally caught at latitudes higher than 55degrees South in the circumpolar waters adjacent to Antarctica. In addition, toothfish are caught outside CCAMLR's Convention Area, mostly taken from domestic fisheries around South America and landed in local ports.
Legally-caught toothfishis usually taken by bottom longlines deployed from vessels of 50-60m in length. Some toothfish is also caught by trawl in the Western Indian Ocean and by pot in the Southwest Atlantic Ocean and off South America. IUU fishing vessels may longline or gillnet, the latter method considered particuarly destructive to the Antarctic marine environment. IUU-caught toothfish is often transhipped at sea and landed in port by cargo vessels. CCAMLR maintains a list of IUU vessels which is available on its website (www.ccamlr.org)
Toothfish are slow-growing and long-lived, reaching maturity at about 8-10 years of age and living for up to 45-50 years. Toothfish caught in the fisheries are typically 80-140cm long and weigh 10-30kg. Large specimens may grow in excess of 160cm and weigh 60-80kg. Toothfish have a fusiform (a gradual narrowing at both ends) body shape, a protruding lower jaw and large lower lip, large eyes and large gill plates.
Dissostichus eleginoides - Patagonian Toothfish
Toothfish may resemble, or may be misreported as or mixed with the following species:
Hake (HKE), Shark, African barrelfish (SEY), Butterfish/Bluenose (BUX) (when filleted), Greenland halibut (GHL) (when filleted and with skin)
If in doubt as to the species identity, sampling of toothfish catch for protein DNA analysis may be considered. Photographs of toothfish products and packaging could also be taken to assist with identification.
Toothfish are normally processed and frozen on board the fishing vessel.
Common basic cuts are: headed, gutted and tailed (HGT) heads, collars and cheeks. Depending on the market, the fish may also be filleted or simply gutted.
All toothfish unloaded or transported must be accompanied by a Dissostichus catch document (DCD) issued subject to the CCAMLR catch Documentation Scheme (CDS). For more information see www.ccamlr.org
Each CCAMLR Contracting Party is required to identify the origin of any Dissostichus spp. landed or imported into or exported from its territories in order to establish if it was caught within the Convention Area according to the Conservation Measures agreed by CCAMLR. Toothfish landed in the port of Contracting Parties will be accompanied by catch and export documents from the point of landing to the point of final consumption. Toothfish without valid documentation cannot be landed in the port of any CCAMLR Contracting Party or subsequently traded. catch documents canot be issued to vessels included on CCAMLR's IUU Vessel Lists.
