Characteristics of autolysis of antarctic krill. [PDF]

Agricultural and Biological Chemistry, 1981
The rate of autolysis after thawing in intact frozen krill (whole body, cephalothorax, and abdomen) and in its homogenates was studied by determining both the increase of TCA-soluble nitrogen and the change of protein pattern in SDS-polyacrylamide gel electrophoresis.Autolysis in the intact state proceeded rapidly in the separated cephalothorax, but ...

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 ...

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

Journal 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

Scientific 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.

Target strengths of Antarctic krill [PDF]

The Journal of the Acoustical Society of America, 1989
Encaged aggregations of Euphausia superba have been ensonified at 38 and 120 kHz and the echo energy measured. Derived estimates of target strength are considerably lower than previously measured values.

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.

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.

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

Environmental 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.

Impacts of local human activities on the Antarctic environment [PDF]

, 2008
We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.
