Feeding behaviour of Antarctic krill on salps
Abstract: Feeding behavior of Antarctic krill (Euphausia superba) on salps was observed through ... 1 salp/krill/day. Among 4 items of ethanol extracts; salps, phytoplankton, krill, and polychaets ... , krill preferred salps best. This evidence implies that the substances extracted from salps were most ... attractive to krill. The result of our experiment might indicate a tight ecological relationship between ...

Size and stage composition of age class 0 Antarctic krill (Euphausia superba) in the ice-water interface layer during winter/early spring
Abstract: The condition and survival of Antarctic krill (Euphausia superba) strongly depends on ... sea ice during winter. How krill utilize sea ice depends on several factors such as region and ... developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains largely ... unknown.
