Swarming and Behaviour in Antarctic Krill

2016
The behavioural ecology of Antarctic krill is dominated by their tendency to swarm. They form amongst the largest monospecific aggregations of biomass in the animal kingdom, with some swarms measuring up to 100 km2 and containing 2 million tonnes of krill.

Genetics of Antarctic Krill

2016
From a genetic perspective, Euphausia superba (krill) can be described as a non-model organism with a large genome and a large population size. The population genetics of krill has been studied extensively and a consensus on population structure is now emerging. Some preliminary characterization of the krill genome has been accomplished, but the genome

Antarctic krill ( Euphausia superba Dana ) eat salps

Polar Biology, 1996
Feeding behaviour of Antarctic krill (Euphausia superba) on salps was observed in shipboard experiments during the 1994/1995Kaiyo Maru Antarctic Ocean research cruise. The feeding rate was more than 0.5 salp/krill per day. When offered ethanol extracts of four prey types, salps, phytoplankton, krill and polychaetes, krill preferred the salp extracts ...

MODELING THE CONSEQUENCES OF ANTARCTIC KRILL HARVESTING ON ANTARCTIC FUR SEALS

Ecological Applications, 2000
In terms of the convention governing the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), management advice for the Antarctic krill (Euphausia superba) fishery should take the needs of the predators of krill into account in order to reduce the risk of deleterious impacts on such predators (e.g., baleen whales and numerous ...

Egg-release behaviour in Antarctic krill

Polar Biology, 2009
The process of egg release is a complex and crucial step in the life cycle of euphausiids, especially with regards mortality and recruitment success. We examined this process in Antarctic krill (Euphausia superba) in terms of the functioning of the female genital apparatus and associated swimming behaviour.

Antarctic Krill: a reappraisal of its distribution

Polar Record, 1976
The past ten years have seen a greatly increased interest in the Antarctic krill Euphausia superba Dana (Fig 1). In particular there have been several Russian expeditions whose main aim has been the evaluation of krill as an exploitable resource (Burukovskiy and Yaragov, 1965) and, more recently, Japanese expeditions have ventured into the Southern ...

Characterization of proteinases from Antarctic krill (Euphausia superba)

Protein Expression and Purification, 2002
Fractions of three trypsin-like proteinases, TL I, TL II, and TL III, a chymotrypsin-like proteinase, CL, two carboxypeptidase A enzymes, CPA I and CPA II and two carboxypeptidase B enzymes, CPB I and CPB II, from Antarctic krill (Euphausia superba) have been characterized with respect to purity by the means of capillary electrophoresis, CE, and matrix-

Antarctic krill vertical migrations modulate seasonal carbon export

Science
Vertical migrations by marine organisms contribute to carbon export by consumption of surface phytoplankton followed by defecation in the deep ocean. However, biogeochemical models lack observational data, leading to oversimplified representation of carbon cycling by migrating organisms, such as Antarctic krill ( Euphausia ...

Krill Consumption by Antarctic Notothenioid Fish

1985
The feeding ecology and the food intake of 4 species of channichthyid fishes (Champsocephalus gunnari, Chaenocephalus aceratus, Pseudochaenichthys georgianus, Chionodraco rastrospinosus) and 3 species of nototheniids (Notothenia rossii marmorata, N. gibberifrons, N. larseni) were studied in western Antarctic waters and off South Georgia.
