The Antarctic Toothfish (Dissostichus mawsoni) is an apex predator foundonly in the Southern Ocean. Antarctic Toothfish are commercially harvested. Theindustry is controversial since it involves humans interfering with a 'pristine'environment. Many environmental groups are concerned that Toothfish fishing couldbe detrimental to the food web structure of the Southern Ocean due to AntarcticToothfish having an apex role within the ecosystem, being long lived, and the factthat little is known about their reproduction. The fisheries for Toothfish are managedby the Convention on the Conservation of Antarctic Marine Living Resources(CCAMLR). The Toothfish is valuable as an economic resource for nations involvedin harvesting, and also valuable from ecological, and scientific perspectives. Thisindustry appears to contradict the environmentally friendly values of New Zealanders;on closer analysis this may not be the case. With careful management the values ofthe Antarctic Toothfish can be maintained for future generations. Most of theliterature comes from the scientific community with little or no publications availablefrom industry bodies on either matters of sustainability or economics.
