Lipids in Euphausia superba

open access: yes, 1995
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 ...

Chemical composition of dried eyeballs from Euphausia superba and Euphausia pacifica

Fisheries Science, 2007
Dried 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.

Development of eggs and nauplii of Euphausia superba

Polar Biology, 1984
The development of eggs and nauplii was studied over 19 days. At 1.5°C nauplii hatched after 5 days. Abdominal spines changed their appearance successively during nauplius development, but no moulting was observed in the course of naupliar development. Moulting occurred between the nauplius and the metanauplius stage 13 days after spawning.

Feeding of the Antarctic Krill Euphausia Superba

Journal of Crustacean Biology, 1984
ABSTRACT 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.

Aspects of Schooling in Euphausia Superba

Journal of Crustacean Biology, 1984
ABSTRACT Divers observed schools of Euphausia superba off the South Shetland Islands and in Gerlache Strait near the Antarctic Peninsula. Euphausiids almost always occurred within the confines of dense schools swimming in one direction. Schools formed an infinite variety of shapes but usually were narrow in at least one dimension, so that individuals ...

DNA as a Dietary Biomarker in Antarctic Krill, Euphausia superba

Marine Biotechnology, 2006
The diet of Antarctic krill (Euphausia superba) has been studied using a variety of techniques, but current methods still suffer from problems that are difficult to solve. This study examined an alternative approach utilizing DNA as a prey biomarker.

Antarctic krill ( Euphausia superba Dana ) eat salps

Polar Biology, 1996
Feeding 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 ...

Characterization of proteinases from Antarctic krill (Euphausia superba)

Protein Expression and Purification, 2002
Fractions 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-
