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 R...
Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance
Antarctic krill Feeding water depth

Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
(Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
Seabed foraging by Antarctic krill: Implications for stock assessment, bentho-pelagic coupling, and the vertical transfer of iron

2014/4/8
A compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar...

We studied the diet of Antarctic krill, Euphausia superba, at five stations across the southwest Atlantic sector in summer 2003 by analyzing stomach content, fatty acids, and stable isotopes on the sa...
Diatom fatty acid biomarkers indicate recent growth rates in Antarctic krill
Diatom fatty acid biomarkers indicate growth rates Antarctic krill

We investigated the relationship between nutritional condition (levels of specific fatty acids) and growth increment (percentage growth per intermoult period, percentage IMP-1) for Antarctic krill (Eu...
Growth rates of Antarctic krill, Euphausia superba: Comparison of the instantaneous growth rate method with nitrogen and phosphorus stoichiometry
Growth rates of Antarctic krill Euphausia superba Comparison of the instantaneous growth rate method with nitrogen phosphorus stoichiometry
2014/5/19
Zooplankton growth rates are hard to measure directly, and proxy measurements are desirable to encompass the variety of species and scales of interest. The growth rate hypothesis of stoichiometric the...
On the use of lipid biomarkers in marine food web analyses: An experimental case study on the Antarctic krill, Euphausia superba
lipid biomarkers marine food web analyses
2014/5/21
The application of marker fatty acids to trace the feeding habits of Euphausia superba (krill) has produced
contradictory results. We examined the effects of various diets on the fatty acid compositi...

Feeding and energy budgets Antarctic krill Euphausia superba Furcilia III larvae
2014/5/27
Physiological condition and feeding behavior of furcilia larvae were investigated in autumn (April 1999) in the southwestern Lazarev Sea prior to the critical overwintering period. Furcilia stage III ...

Feeding and energy budgets Antarctic krill Euphausia superba Juveniles and adults
2014/5/27
The overwintering success of Euphausia superba is a key factor that dictates population size, but there is uncertainty over how they cope with the scarcity of pelagic food. Both nonfeeding strategies ...
