A critical issue for feedback management – how do we determine the level of functional overlap between krill fishing operations and penguin foraging activity?
Abstract: The spatial distribution of the Antarctic krill fishery in Subareas 48.1 to 48.3 has ... changed over time. The majority of catches in Subarea 48.1 are now taken south of the South Shetland ... Islands, following regional decreases in seasonal sea-ice cover. As the cumulative spatial footprint of ... the fishery has expanded along the West Antarctic Peninsula, the cumulative numbers of krill-eating ...
