Euphausia superba
The Antarctic krill (Euphausia superba Dana 1852) is widely distributed throughout the southern ocean, where it provides a key link between primary producers and upper trophic levels and supports a major commercial fishery. Despite its ecological and commercial importance, genetic population structure of the Antarctic kill remains poorly described. In an attempt to illuminate genetic markers fo...
متن کاملEuphausia superba in the laboratory
Using systems for long-term maintenance of Antarctic krill Euphausja superba in aquana , positive growth was measured in a large number of specimens under controlled conditions. The first moult always showed the greatest growth increment. The high laboratory growth rates agreed with previous field investigations. Often-reported 'abnormal' slow and predominantly negative growth was probably due ...
متن کاملThe opsin repertoire of the Antarctic krill Euphausia superba.
The Antarctic krill Euphausia superba experiences almost all marine photic environments throughout its life cycle. Antarctic krill eggs hatch in the aphotic zone up to 1000m depth and larvae develop on their way to the ocean surface (development ascent) and are exposed to different quality (wavelength) and quantity (irradiance) of light. Adults show a daily vertical migration pattern, moving do...
متن کاملSize Selection of Antarctic Krill (Euphausia superba) in Trawls
Trawlers involved in the Antarctic krill (Euphausia superba) fishery use different trawl designs, and very little is known about the size selectivity of the various gears. Size selectivity quantifies a given trawl's ability to catch different sizes of a harvested entity, and this information is crucial for the management of a sustainable fishery. We established a morphological description of kr...
متن کاملFatty Acid Component of Lipid of Euphausia Superba
Lipids extracted from the raw frozen and boiled-frozen krill, Euphausia superba, harvested in the Antarctic Ocean were identified and quantitated by a combination of thin-layer and gas-liquid chromatography. The lipid contents of E. superba on the wet weight basis were 3.41% of the raw frozen sample and 5.62% of the boiled-frozen sample. There were shown to consist of 0.8% of steryl esters, 27....
