The importance of Antarctic krill in biogeochemical cycles [PDF]

open access: yesNature Communications, 2019
AbstractAntarctic krill (Euphausia superba) are swarming, oceanic crustaceans, up to two inches long, and best known as prey for whales and penguins – but they have another important role. With their large size, high biomass and daily vertical migrations they transport and transform essential nutrients, stimulate primary productivity and influence the ...

Comparative Analysis of the Fatty Acid Profiles of Antarctic Krill (Euphausia superba Dana, 1850) in the Atlantic Sector of the Southern Ocean: Certain Fatty Acids Reflect the Oceanographic and Trophic Conditions of the Habitat

open access: yesJournal of Marine Science and Engineering, 2023
The present study is the attempt to combine oceanologic measurements and biochemical analysis, which is as possible to implement on board as in a laboratory with chosen certain statistics to reveal trophic conditions and the environment state in which ...

Quantifying Antarctic krill connectivity across the West Antarctic Peninsula and its role in large-scale Pygoscelis penguin population dynamics

open access: yesScientific Reports, 2023
Antarctic krill (Euphausia superba) are considered a keystone species for higher trophic level predators along the West Antarctic Peninsula (WAP) during the austral summer.

The hydrodynamics of hovering in Antarctic krill [PDF]

open access: yesLimnology 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.

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

open access: yesPLoS 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

open access: yesShipin 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.

Glacial melting: an overlooked threat to Antarctic krill [PDF]

open access: yesScientific 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 ...

Preparation of Antarctic Krill Oil Emulsion and Its Stability under Catalase Treatment

open access: yesFoods, 2021
Making Antarctic krill oil into emulsion is a good way to utilize Antarctic krill, but proliferation of microorganisms cannot be ignored. H2O2 is widely used in the sterilization of liquid food since its decomposition products are environmentally ...

Environmental DNA of Antarctic krill (Euphausia superba): Measuring DNA fragmentation adds a temporal aspect to quantitative surveys

open access: yesEnvironmental DNA, 2023
Antarctic krill (Euphausia superba) is a keystone species in the Southern Ocean ecosystem, and monitoring its distribution and abundance is crucial for the sustainable management of expanding fisheries targeting the species.

Adult Antarctic Krill Feeding at Abyssal Depths [PDF]

open access: yesCurrent 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 ...
