Managing fisheries to conserve the Antarctic marine ecosystem: practical implementation of the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR)
Abstract: Apart from exploitation of seals and whales, Antarctic fisheries began in the late ... 1960s with exploitation of the marbled rockcod, Notothenia rossii, in the South Atlantic, a species ... decimated in the first two years of the fishery following catches of about 500,000t. Two other species have ... formed the basis of substantial fisheries, krill (Euphausia superba) and mackerel icefish ...
