climate condition reproduction of krill SAM MEI seasonal variation
2021/8/4
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new s...
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
2014/4/2
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...

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...
