Antarctic toothfish
dissostichus mawsoni latin

Antarctic toothfish have been caught to depths of 2200m, though based on commercial fishing effort, few occur that deep.

Antarctic toothfish have vision and lateral line systems well adapted to find prey in low light levels.

The Antarctic toothfish's voracious appetite also is important in coping with cold water.

It was brought to the surface as it fed on an Antarctic toothfish that had been caught off a long line.

Aging data indicate that Antarctic toothfish are relatively fast growing when young, but then growth slows later in life.

Greenpeace International also added the Antarctic toothfish to its seafood red list in 2010.

The habitat of the Antarctic toothfish is in sub-zero degree water below latitude 60 degrees south.

Due to the low water temperatures around the mainland, the Antarctic toothfish has antifreeze proteins in its blood and tissues.

Only a few Antarctic toothfish with mature eggs have ever been caught, meaning that knowledge is sparse about fecundity.

The recruitment potential of Antarctic toothfish, a measure of both fecundity and survival to spawning age, is not known.

Another abundant fish group is the Notothenia genus, which like the Antarctic toothfish have antifreeze in their bodies.

This fishery catches mainly Antarctic toothfish, a close relative to the Patagonian toothfish.

Aiding in that role, the Antarctic toothfish is one of only five notothenioid species that, as an adult, are neutrally buoyant.

The Antarctic toothfish, Dissostichus mawsoni, is a perciform member of the suborder Notothenioidei, family Nototheniidae.

Antarctic toothfish have a lightweight, partially cartilaginous skeleton, lack a swim bladder, and have fatty deposits which act as a stored energy source, particularly during spawning.

The Commission's opinion on the proposal to include species of Patagonian and Antarctic toothfish in Appendix II is based on the same principle.

Diet of the Antarctic toothfish (Dissostichus mawsoni) from the Ross Sea, Antarctica (Subarea 88.1).

CCAMLR imposes stringent environmental protection and bycatch mitigation measures to Antarctic toothfish fisheries including:

Moreover, MSC-certified Antarctic toothfish comprised only 1% of total toothfish caught in the Southern Ocean in 2010.

The presence of antifreeze glycroproteins allows the Antarctic toothfish (and other notothenioids) to thrive in sub-zero waters of the Southern Ocean surrounding Antarctica.

It is preyed upon by the ploughfish, Gymnodraco acuticeps, the Antarctic toothfish, Dissostichus mawsoni, and the emperor penguin, Aptenodytes forsteri.

In November 2010, the Marine Stewardship Council certified the Ross Sea Antarctic Toothfish fishery as a sustainable and well managed fishery.

There are two species from the Dissostichus genus, the Antarctic toothfish (Dissostichus mawsoni) and the Patagonian toothfish (Dissostichus eleginoides).

Antarctic toothfish take a long time to mature (13 years for males, 17 years for females) and once mature may not spawn every year, though the actual spawning interval is unknown.

Antarctic toothfish also have a very well developed sense of smell, which is why they are easily caught by baited hooks and also scavenge the remains of penguins killed by other predators.
