1. Characterising the preferred at-sea habitats used by chinstrap penguins and the fishery for Antarctic krill: slow-flowing, nearshore waters over shallow bathymetry

   habitats are also locations preferentially used by the commercial krill fishery. Cross-shelf submarine ... canyons occur near to a number of preferred krill fishing locations, suggesting that these canyons ... potentially play an important role in krill transport onto the shelf. In the relatively slow-moving shelf ... waters krill depletion is probably more likely and krill replenishment less likely. Our results suggest ...
