Pygoscelis penguin diets on King George Island, South Shetland Islands, with a special focus on the krill Euphausia superba

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 ...

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 ...

Eight antihypertensive peptides from the protein hydrolysate of Antarctic krill (Euphausia superba): Isolation, identification, and activity evaluation on human umbilical vein endothelial cells (HUVECs).

Food Research International, 2019
In this report, eight antihypertensive peptides were isolated from protein hydrolysate of Antarctic krill (Euphausia superba) using ultrafiltration and chromatography consecutively, and their sequences were identified as Trp-Phe, Tyr-Arg-Lys-Glu-Arg, Tyr-

Lipids in Euphausia superba

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 ...

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.

Flexibility in Antarctic krill Euphausia superba decouples diet and recruitment from overwinter sea-ice conditions in the northern Antarctic Peninsula

, 2020
Winter sea-ice conditions are considered important for Antarctic krill Euphausia superba survival and recruitment, yet few broad-scale longitudinal studies have examined the underlying relationships between winter conditions and krill recruitment.

Effect of chitosan coatings incorporated sodium phytate on the shelf-life of Antarctic krill (Euphausia superba).

International Journal of Biological Macromolecules, 2020
Chitosan is a preservative with potent antibacterial activity, and sodium phytate has antioxidant activity and potent ion chelating ability. The present work aimed to explore the effects of chitosan coating combined with sodium phytate (0.1% sodium ...
