Chemical composition of dried eyeballs from Euphausia superba and Euphausia pacifica
Fisheries Science, 2007Dried krill eyeballs were obtained from Euphausia superba and Euphausia pacifica by using a patented industry method and their chemical compositions were examined. Crude protein content was 77.7% and 80.8% of the dry matter of E. superba and E. pacifica, respectively.

Aspects of the life history and overwintering survival strategies of Antarctic krill (Euphausia superba) were interpreted through analyses of lipid class, fatty acid and sterol content, and composition. Both laboratory and field studies were undertaken to provide information on the biochemical and physiological consequences of starvation, on dietary ...

Selective carnivory by Euphausia lucens
Continental Shelf Research, 1991Abstract Stomach contents of adult Euphausia lucens were analysed to determine what criteria this euphausiid uses to select copepod prey. The results indicate that although E. lucens of all sizes ingest a wide range of prey sizes at apparently ambient proportions, small copepods (e.g.

Antarctic krill ( Euphausia superba Dana ) eat salps
Polar Biology, 1996Feeding behaviour of Antarctic krill (Euphausia superba) on salps was observed in shipboard experiments during the 1994/1995Kaiyo Maru Antarctic Ocean research cruise. The feeding rate was more than 0.5 salp/krill per day. When offered ethanol extracts of four prey types, salps, phytoplankton, krill and polychaetes, krill preferred the salp extracts ...

Microplastics in Antarctic krill (Euphausia superba) from Antarctic region
Science of The Total Environment, 2023Pollution of microplastics (MPs) has become a potential threat to Antarctic marine ecosystems. However, the occurrence of MPs in Antarctic krill (Euphausia superba), a keystone species in Antarctic ecosystems, remains unclear. In this study, the abundance and characteristics of MPs were examined in Antarctic krill samples (n = 437) collected from two ...

Journal of Ocean University of China, 2016
The information of trophic relationship is important for studying the Southern Ocean ecosystems. In this study, three dominant krill species, Euphausia superba, Thysanoessa macrura and Euphausia crystallorophias, were collected from Prydz Bay, Antarctica, during austral summer of 2009/2010. The composition of fatty acids in these species was studied. E.

Energy Flow in Euphausia pacifica
Nature, 1967To understand relationships within food webs in the sea, with an eye to predicting and perhaps ultimately improving the efficiency of the production of commercially important species, we must understand the energetics of the lower elements of the food web.

Characterization of proteinases from Antarctic krill (Euphausia superba)
Protein Expression and Purification, 2002Fractions of three trypsin-like proteinases, TL I, TL II, and TL III, a chymotrypsin-like proteinase, CL, two carboxypeptidase A enzymes, CPA I and CPA II and two carboxypeptidase B enzymes, CPB I and CPB II, from Antarctic krill (Euphausia superba) have been characterized with respect to purity by the means of capillary electrophoresis, CE, and matrix-

Feeding of the Antarctic Krill Euphausia Superba
Journal of Crustacean Biology, 1984ABSTRACT Measurements of rates of feeding indicate that Euphausia superba can feed on particles ranging from nanophytoplankton to macrozooplankton; a typical animal of 120 mg dry weight processes about 450 ml water per h and ingests at a maximum about 10% of its body carbon per day.
