Patagonian toothfish, marketed as Chilean Seabass, is a large, slow-growing deep-sea species found around the Southern Hemisphere, primarily off the coasts of Chile, Argentina and around sub-Antarctic islands. The species has been vulnerable to over-exploitation and its high commercial value has made it a constant target of illegal, unregulated and unreported fishing. A 2013 Monterey Bay Aquarium report indicated that Patagonian toothfish stocks around South Georgia, Heard and McDonald Islands, Macquarie Island and the Falkland Islands are abundant. Stocks in the Ross Sea appear to be doing well but there was uncertainty about the measurements. The Prince Edward and Marion Islands stocks were depleted, Crozet stocks were unassessed and highly vulnerable, while the Chilean fishery was assessed as being overfished.
