Winter condition, physiology, and growth potential of juvenile Antarctic krill

Frontiers in Marine Science, 2022
In recent years, substantial efforts have been made to understand the implications of climate change on Antarctic krill, Euphausia superba, because of their pivotal role in the Southern Ocean food web and in biogeochemical cycling.

The Krill Problem in Antarctica [PDF]

Oryx, 1981
Krill fishing in the Southern Ocean has raised in acute form the question of wildlife conservation in Antarctica: what will be the effect on the ecosystem? how much krill can be taken? who can take part? what regulations are needed? The author, a scientist of the British Antarctic Survey, considers the answers in the light of the Antarctic Treaty of ...

At-Sea Distribution and Prey Selection of Antarctic Petrels and Commercial Krill Fisheries.

PLoS ONE, 2016
Commercial fisheries may impact marine ecosystems and affect populations of predators like seabirds. In the Southern Ocean, there is an extensive fishery for Antarctic krill Euphausia superba that is projected to increase further.

Krill Oil Inhibits Cholesterol Synthesis and Stimulated Cholesterol Excretion in Hypercholesterolemic Rats

Marine Drugs, 2022
The present study aimed to investigate the antihypercholesterolemic effects of krill oil supplementation in high-cholesterol diet-induced hypercholesterolemic rats, and the mechanisms underlying these effects.

Insight into the Gel Properties of Antarctic Krill and Pacific White Shrimp Surimi Gels and the Feasibility of Polysaccharides as Texture Enhancers of Antarctic Krill Surimi Gels

Foods, 2022
Antarctic krill is a potential and attractive resource for consumption. However, most Antarctic krill meat is used to produce primary products with low commercial value, with few highly processed products.

Spatial link between Adélie penguin foraging effort and krill swarm abundance and distribution

Frontiers in Marine Science, 2023
Understanding how predator foraging behaviour is influenced by the distribution and abundance of prey is a fundamental challenge in marine foraging ecology. This is particularly relevant in Southern Ocean ecosystems where the relationships between select

A thorough annotation of the krill transcriptome offers new insights for the study of physiological processes

Scientific Reports, 2022
The krill species Euphausia superba plays a critical role in the food chain of the Antarctic ecosystem. Significant changes in climate conditions observed in the Antarctic Peninsula region in the last decades have already altered the distribution of ...

Monitoring Antarctic krill (Euphausia superba) distribution in the Southern Ocean: environmental DNA (eDNA) adds to the toolbox

Frontiers in Marine Science
Antarctic krill (Euphausia superba Dana) is a key species of the Southern Ocean ecosystem, immensely abundant and targeted by the krill fishery. For their sustainable management, krill distribution and biomass estimates are required, typically achieved ...

Hemispherical Distribution of Antarctic Krill Indicates High Abundance in Amundsen Sea

Oceans
Antarctic krill (Euphausia superba) are an essential source of food for whale, seal, several fish, squid and seabird species in the Southern Ocean. Krill also play a major role in biogeochemical cycling and are the target of a growing commercial fishery.

Krill excretion boosts microbial activity in the Southern Ocean.

PLoS ONE, 2014
Antarctic krill are known to release large amounts of inorganic and organic nutrients to the water column. Here we test the role of krill excretion of dissolved products in stimulating heterotrophic bacteria on the basis of three experiments where ...
