Patagonian Toothfish, Dissostichus eleginoides
Patagonian Toothfish is caught predominantly by longline in deep waters in the remote Southern Ocean. Small amounts of fish are also caught by trawl, though increasingly this method is used only for scientific surveying. Patagonian Toothfish are thought to live up to 50 years and can grow as large as 2m and over 100kg, though commonly caught at around 4-7kg. Legal fishing is strictly controlled, but illegal fishing does occur in international waters. Hard work by Australian customs vessels has eradicated illegal fishing in Australian waters., with no illegal fishing recorded since 2005. The Patagonian Toothfish fishery in Australia suffered a similar fate to global stocks when first discovered, being dramatically overfished by illegal operators. However, a collaborative effort between the fishing industry and government fishery agencies in recent have seen a dramatic turn around, with Patagonian Toothfish fisheries now considered well-managed. The majority of the fish caught by Australian boats is sold overseas to Chinese and US markets. Though unattractive whole, when filleted the fish yields a large firm very white piece of flesh with no pin bones, an indication of why it is so popular and valuable to fisheries, especially as a frozen product. 'Glacier 51' Toothfish is a premium product that comes from the MSC certified fishery around Heard and McDonald Islands in the Southern Ocean. Also known as 'Sea Bass', 'Chilean Sea Bass' or 'Australian Sea Bass', though the Australian Fish Names Standard requires it to be sold only as Patagonian Toothfish.

The why and how of sustainability
The Patagonian Toothfish has a bad history, with a biology unsuited to intense fishing, widespread illegal catch and seabird deaths causing conservation agencies the world over to say “no” to choosing this Antarctic delicacy. The Australian fishery has come a long way in recent years, attaining Marine Stewardship Council (MSC) certification for all the Australian fisheries in 2012. Additionally, Australian customs have successfully deterred much illegal fishing and managers have reduced seabird deaths to very low numbers. All toothfish sold in Australia must be documented as legally caught, so no illegal catch reaches our shores.
