Interactions between krill and its predators in the western Ross Sea

Frontiers in Marine Science
Krill is a fundamental resource in the pelagic food web of the Ross Sea, constituting an important link between primary production and top predators.

A study on the multi-frequency acoustic target strength of krill using a stochastic distorted-wave born approximation (SDWBA) model

Fisheries and Aquatic Sciences
We examined the dB difference in target strength at multiple frequencies (ΔTS) for the identification of Antarctic krill (Euphausia superba) and ice krill (Euphausia crystallorophias) using a stochastic distorted-wave Born approximation model.

Systematic sequencing of mRNA from the Antarctic krill (Euphausia superba) and first tissue specific transcriptional signature

BMC Genomics, 2008
Background Little is known about the genome sequences of Euphausiacea (krill) although these crustaceans are abundant components of the pelagic ecosystems in all oceans and used for aquaculture and pharmaceutical industry.

Hypoxia Tolerance of 10 Euphausiid Species in Relation to Vertical Temperature and Oxygen Gradients

Frontiers in Physiology, 2020
Oxygen Minimum Zones prevail in most of the world’s oceans and are particularly extensive in Eastern Boundary Upwelling Ecosystems such as the Humboldt and the Benguela upwelling systems.

Trace element concentration in Antarctic krill reflecting their distribution in the Weddell Sea

Russian Journal of Earth Sciences, 2021
Distribution of Al, As, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Rb, and Zn in the main body parts and total samples of juvenile Antarctic krill Euphausia superba was examined in the northeastern Weddell Sea.

The complete mitochondrial genome of the ice krill Euphausia crystallorophias Holt & Tattersall, 1906 (Euphausiacea, Euphausiidae), from the Ross Sea, Antarctica

Mitochondrial DNA. Part B. Resources
The mitogenome of Euphausia crystallorophias collected from the Ross Sea Region Marine Protected Area (RSR MPA) is described for the first time. The assembled mitogenome was 17,291 bp in length and consisted of two ribosomal RNAs (rRNAs), 22 transfer ...

Improving the Accuracy of Krill Target Strength Using a Shape Catalog

Frontiers in Marine Science, 2021
Antarctic krill are subject to precautionary catch limits, based on biomass estimates, to ensure human activities do not adversely impact their important ecological role.

Effect of body size, temperature and starvation on oxygen consumption of antarctic krill Euphausia superba

Brazilian Journal of Oceanography, 1997
Routine oxygen consumption of krill was investigated as a general measure of its metabolism and assesses the effects of body size, temperature and starvation on the metabolism. No significant difference in whole animal consllmption was detected after 1,3,

Resource potential and maturity estimates of Euphausia superba in East Antarctica

Frontiers in Marine Science
The East Antarctic krill fisheries are spread across two Divisions of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), Division 58.4.1 between 80-150°E and Division 58.4.2 between 30-80°E.
