Adult Antarctic Krill Feeding at Abyssal Depths [PDF]
Current Biology, 2008 Antarctic krill (Euphausia superba) is a large euphausiid, widely distributed within the Southern Ocean [1], and a key species in the Antarctic food web [2]. The Discovery Investigations in the early 20(th) century, coupled with subsequent work with both nets and echosounders, indicated that the bulk of the population of postlarval krill is typically ...

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia [PDF]
, 2007 South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...

Glacial melting: an overlooked threat to Antarctic krill [PDF]
Scientific Reports, 2016 AbstractStrandings of marine animals are relatively common in marine systems. However, the underlying mechanisms are poorly understood. We observed mass strandings of krill in Antarctica that appeared to be linked to the presence of glacial meltwater. Climate-induced glacial meltwater leads to an increased occurrence of suspended particles in the sea ...

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.

Optimization of Decolorization Process of Antarctic Krill Peptides by Response Surface Methodology
Shipin gongye ke-ji, 2022 In order to optimize the decolorization process of Antarctic krill peptides and improve the product quality, activated carbon adsorption method was used to remove the pigment from the Antarctic krill peptides solution.

Classification of Proteases in Antarctic Krill
Agricultural and Biological Chemistry, 1983 The species of endogenous proteases in Antarctic krill, Euphausia superba, were investigated using the homogenate of krill and the active fractions after gel filtration of the homogenate as to the following criteria: Substrate specificity (benzyloxycarbonyl (Z)-Phe-Ala, Z-Glu-Tyr, hippuryl-Arg, hippuryl-Phe, benzoyl Arg-p-nitroanilide, Leu-p ...

The hydrodynamics of hovering in Antarctic krill [PDF]
Limnology and Oceanography: Fluids and Environments, 2013 Lay AbstractAntarctic krill, one of the most important species of the Southern Ocean ecosystem, are denser than water and must swim continuously to avoid sinking. They swim by beating their five pairs of swimming legs in a sequential pattern from back to front.
