More Info


Widespread in continental slope waters from off Chile and Argentina south of 30–35°S, to Subantarctic islands and continental shelf areas of the Southern Ocean.


Opportunistic carnivores. Juveniles feed in the water column on krill in coastal waters. As they grow and migrate to deeper waters, they prey more on fishes.


Reach a length of over 2.2 m, and live to more than 50 years. Patagonian Toothfish spawn from July to September,, possibly releasing their eggs in continental slope depths of  800-1000 metres. 


Fished commercially around Macquarie Island in the Southern Ocean, Australian EEZ - 1500km south east of Tasmania. Patagonian Toothfish is taken by automated longline and bottom trawl, and most of the catch is exported to the USA, China and Japan.


Dissostichus is from the Greek disso meaning 'twice', 'one or other', and stix, stichos meaning 'line' or 'row' in reference to the two lateral lines. The specific name eleginoides is derived from the genus Eleginops for an assumed resemblance to that genus.
