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 Science, 2020
In the krill-based ecosystem of the Antarctic, fluctuations in the distribution and abundance of Euphausia superba may have strong impacts on predator populations; thus, it is crucial to observe the feeding ecology of Antarctic predators, especially in ...

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 ...

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.

BACKGROUND Antarctic krill is a huge source of biomass and prospective high-quality lipid source. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), nutritionally important lipid components with poor oxidative stability, were used as markers of ...

Chitosans from Euphausia superba. 1: Solution properties
Carbohydrate Polymers, 1992Abstract A technological development of chitosan (copolymer of N -acetylglucosamine and glucosamine) is based on the knowledge of parameters such as composition. types of sequence, chain length and distribution. In addition to the sample source, these factors are related to preparation and purification methods.

Condition indicators for Antarctic krill, Euphausia superba
2023Antarctic krill use a variety of strategies to cope with, and thrive in the highly variable Southern Ocean environment. Despite much detailed information on its basic biology produced so far, the linkages between krill populations and the environment are yet to be systematically investigated. There is a practical need to have standardised indicators to
