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 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.

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.

Images as proximity sensors : the incidence of conspecific foraging in Antarctic fur seals [PDF]

, 2015
Background: Although there have been recent advances in the development of animal-attached ‘proximity’ tags to remotely record the interactions of multiple individuals, the efficacy of these devices depends on the instrumentation of sufficient animals ...

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 ...

Di(2-ethylhexyl) adipate (DEHA) detection in Antarctic krill (Euphasia superba Dana)

Polar Research, 2018
In this reported study, a novel high-performance thin-layer chromatography (HPTLC) method was developed for the detection and quantification of the toxic substance di(2-ethylhexyl) adipate (DEHA) in Antarctic krill.

Swarms of diversity at the gene cox1 in Antarctic krill [PDF]

Heredity, 2010
The Antarctic krill, Euphausia superba, is an abundant and key species found in the Southern Ocean that forms dense, discrete swarms. Despite over three decades of research on Antarctic krill, the genetics of individual swarms is yet to be specifically investigated.

Influence of individual state on swimming capacity and behaviour of Antarctic krill Euphausia superba [PDF]

, 2008
Swarms of Antarctic krill are frequently biased towards certain body sizes, sexes, maturities and physiological states. However, the mechanisms causing such biases remain unclear, with some speculating on differential responses to chemical or visual cues.

Multi-species models of Antarctic krill predators : do competitive effects influence estimates of pre-exploitation whale abundance and recovery? [PDF]

, 2008
Includes abstract. Includes bibliographical references (leaves 92-111).Many species of baleen whales and seals in the Southern Hemisphere were subject to intensive overexploitation by commercial harvesting in the last two centuries, and many populations

Setting a Precautionary Catch Limit for Antarctic Krill [PDF]

Oceanography, 2002
A revised precautionary catch limit for Antarctic krill (Euphausia superba) in the Scotia Sea of 4 million tons was recently adopted by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). The limit was based on a total biomass of 44.3 million tons, as estimated from an acoustic and net survey of krill across the Scotia ...
