Microplastics in Antarctic krill (Euphausia superba) from Antarctic region

Science of The Total Environment, 2023
Pollution of microplastics (MPs) has become a potential threat to Antarctic marine ecosystems. However, the occurrence of MPs in Antarctic krill (Euphausia superba), a keystone species in Antarctic ecosystems, remains unclear. In this study, the abundance and characteristics of MPs were examined in Antarctic krill samples (n = 437) collected from two ...

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 ...

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

Breeding antarctic krill in captivity

Marine and Freshwater Behaviour and Physiology, 2003
Antarctic krill were maintained in large aquaria at Port of Nagoya Aquarium, Japan, under controlled photoperiod and were fed on phytoplankton and enriched animal feed. Maturation and spawning were induced after the light : dark (L : D) cycle was increased from 8 : 16 or 12 : 12 to 24 : 0, or when the L : D cycle was held constant at 14 : 10.

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 ...

Tug‐of‐war for the antarctic krill

Ocean Development & International Law, 1980
Abstract A polarization has emerged concerning Antarctic krill. Those who see the krill as an abundant food source are opposed by those who view the expanding krill fishery as a threat to the Antarctic ecosystem. The author discusses the biological basis of expected krill harvests, examines the arguments concerning conservation and preservation, and ...

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.

Morphological and biochemical differentiation in Antarctic krill

Journal of Marine Systems, 2009
Abstract During the February 1981 cruise FIBEX MD-25 between 30–50°E and 61–64°S, hydrography showed the presence of two gyres, confirmed by the geostrophic circulation relative to 1000 m from Levitus climatology, at the borders of these gyres concentrations of highly morphologically differentiated krill were found.

Scales of Interaction Between Antarctic Krill and the Environment

1988
A conceptual framework to allow a constructive approach to the analysis of the Antarctic marine ecosystem taking into account the variability of the system was developed. The temporal and spatial scale relationships of biotic and abiotic processes were found to be important in the investigation of ecosystem structure.
