A critical issue for feedback management – how do we determine the level of functional overlap between krill fishing operations and penguin foraging activity?
whether this has lead to competition for resources between the fishery and these penguins. Such ... footprint in Subarea 48.2 has stayed relatively constant over time. This contrast offers the potential for ... an experiment to establish whether functional overlap occurs and how it affects penguin colonies ... . Such an experiment would necessarily require endorsement by the Scientific Committee and the Commission ...
