The importance of sea ice association of Antarctic krill for transport and retention in the South Orkneys region: a modelling study
of Antarctic krill in CCAMLR Area 48. The local krill populations support krill-dependent higher predators ... and krill fisheries, and the regional oceanographic circulation provides connections between the Antarctic ... for Antarctic krill, and how krill use the sea ice habitat can impact their distribution. To better determine ... the local ecosystem dynamics in this key region requires greater understanding of the extent to which krill ...

A comparison of Antarctic krill (Euphausia superba Dana) caught by nets and taken by macaroni penguins (Eudyptes chrysolophus Brandt): evidence for selection?
, we examined the potential selection of different length and maturity stages of Antarctic krill ... the probability of obtaining length-frequency distributions of krill different from that obtained from the net ... samples. The krill taken by the macaroni penguins differed significantly from those caught in the nets ... . Small krill (28 to 38 mm) were absent from the stomach samples, whereas large krill (58 to 62 mm) were ...
