Do krill fisheries compete with macaroni penguins? Spatial overlap in prey consumption and krill catches during winter
, the macaroni penguin, and the krill fishery by examining the spatial overlap in prey consumption and catches ... as this is the only time of year when spatio-temporal overlaps between macaroni penguin foraging and the krill fishery ... during the winter period. We combined these to produce a surface of the tonnes of krill consumed which ... could be compared directly with the spatial distribution of the tonnes of krill caught by the fishery ...
