Impact of climate change on Antarctic Krill
Antarctic krill Euphausia superba (hereafter ‘krill’) occurs in regions undergoing rapid environmental change, particularly loss of winter sea ice. During recent years, harvesting of krill has increased, possibly enhancing stress on krill and Antarctic ecosystems. This article reviews the overall im...

Antarctic krill Euphausia superba (hereafter ‘krill’) occurs in regions undergoing rapid environmental change, particularly loss of winter sea ice. During recent years, harvesting of krill has increased, possibly enhancing stress on krill and Antarctic ecosystems. This article reviews the overall impact of climate change on krill and Antarctic ecosystems, discusses implications for an ecosystem-based fisheries management approach, and identifies critical knowledge gaps. Sea ice decline, ocean warming, and other environmental stressors act in concert to modify the abundance, distribution and life cycle of krill. Although some of these changes can have positive effects on krill, their cumulative impact is most likely negative. Recruitment, driven largely by the winter survival of larval krill, is probably the population parameter most susceptible to climate change.
