Precautionary management of the Antarctic krill fishery at small spatial scales in the context of regional climate variability: pros and cons of coastal buffers, closed areas and move-on rules
changes in the oceanic domain add to the complexity of managing the Antarctic krill fishery, particularly ... plausible that removals of even small amounts of krill could have reduced foraging opportunities. We discuss ... three management tools that could provide conservation benefits for near-shore krill-dependent species ... buffers closed to fishing during the penguin breeding season could reduce krill catches by approximately ...
