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 ...

Variation in Antarctic Petrel Foraging Ecology: Not All Individuals Specialize on Krill

Frontiers in Marine Science, 2022
Individual heterogeneity in foraging behaviour determines how individuals and populations respond to changes in the availability and distribution of resources.

南极磷虾油氧化稳定性研究进展Progress on oxidation stability of Antarctic krill (Euphausia superba) oil

Zhongguo youzhi, 2022
南极磷虾油是一种富含n-3多不饱和脂肪酸的功能性油脂。为提升南极磷虾油的氧化稳定性，首先简要介绍了影响南极磷虾油氧化稳定性的脂质组成要素，概括了不同加工方式对南极磷虾油氧化稳定性的影响，在此基础上详述以传统脂质氧化指标、微量成分含量变化、挥发性成分、脂质组学评估南极磷虾油氧化稳定性的现状。南极磷虾油的脂质劣变机制复杂，氧化状况评估困难，未来应筛选出合理化评估南极磷虾油氧化稳定性的方法，并系统研究其脂质组成与氧化稳定性之间的量效关系。 Antarctic krill oil is a ...

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.

The energetic cost of early reproductive development in juvenile Antarctic krill at the Western Antarctic Peninsula

Frontiers in Marine Science, 2022
The overwinter survival mechanisms of Antarctic krill, Euphausia superba, are poorly characterized, especially for juveniles. It has been suggested that juveniles adopt a mix of strategies characteristic of both larvae and adults.

Effect of Ultrasound-Assisted Thawing on the Quality of Euphausia superba and Its Changes during Cold Storage [PDF]

Shipin Kexue, 2023
In order to study the effect of ultrasound-assisted thawing on the quality of Antarctic krill (Euphausia superba) and its changes during cold storage, frozen Antarctic krill was placed into net bags or polyethylene (PE) bags and thawed by water immersion

Linking Antarctic krill larval supply and recruitment along the Antarctic Peninsula [PDF]

Integrative and Comparative Biology, 2020
SynopsisAntarctic krill (Euphausia superba) larval production and overwinter survival drive recruitment variability, which in turn determines abundance trends. The Antarctic Peninsula has been described as a recruitment hot spot and as a potentially important source region for larval and juvenile krill dispersal.

The opsin repertoire of the Antarctic krill Euphausia superba [PDF]

Marine Genomics, 2016
The Antarctic krill Euphausia superba experiences almost all marine photic environments throughout its life cycle. Antarctic krill eggs hatch in the aphotic zone up to 1000m depth and larvae develop on their way to the ocean surface (development ascent) and are exposed to different quality (wavelength) and quantity (irradiance) of light.

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 ...
