Managing Southern Ocean krill and fish stocks in a changing environment

Management of Antarctic krill, Euphausia superba, and the mackerel icefish, Champsocephalus gunnari under the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is discussed in relation to changes in their distribution and abundance arising from variation in circulation of...
