1. 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 ...
