Patagonian Toothfish, more commonly known as Chilean Sea Bass, are widely distributed in the Southern Hemisphere south of 40°S latitude. It is a long-lived species that is thought to reach 50 years in age. Sexual maturity is reached between 6-12 years and fecundity is moderate.

Due to its high commercial value, Patagonian Toothfish has been targeted by illegal, unregulated and unreported (IUU) fishers, which have depleted some populations. The Commission for the Conservation of Antarctic Marine Living Resources is the principal managing authority for Patagonian Toothfish and has made a concerted effort in the past decade to eliminate IUU fishing. However a small but persistent level remains.

In these regions, effective management measures have been put in place to ensure Patagonian Toothfish populations remain at healthy abundances and minimize fishing affects on non-target species. Patagonian Toothfish are caught with bottom longlines, which can cause some damage to bottom ocean habitats.
