Antarctic krill (Euphausia superba) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
The SCAR Krill Expert Group (SKEG) aims to improve the understanding of krill biology and ecology and serve as a link between the scientific krill community and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which manages the Antarctic krill fishery.
The annual meeting of the SCAR Krill Action Group (SKAG) was held online from 7 to 11 March 2022 at 1500-1700 UTC as a series of Zoom meetings, and attended by around 60 participants each day. The meeting consisted of SKAG administrative updates…
Here we present preliminary results on krill distribution from data collected from the Norwegian fishing vessel (F/V) Antarctic Endurance during her commercial operation for Antarctic krill in subareas 48.1 and 48.2 during different timings of the year in 2020, 2021 and 2022.
The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
Reliable estimates of diets are vital to monitor impacts of sea lion populations … on their ecosystems and their interactions with fisheries, and to … understand the role of food to animal nutrition and health. Approaches … include using (1) prey remnants in stomach contents, spews and scats; … (2)…
There are very strong thermal gradients between the Antarctic continent and the … sea-ice zone, and between that zone and the ocean to the north. As a result of these contrasts … the sea-ice domain is one of strong cyclogenesis and high cyclone frequency.
In January and February 2000, a collaborative survey designed to assess the biomass of Antarctic krill across the … Scotia Sea was conducted aboard research vessels from Japan, Russia, the UK and the USA using active acoustic and … net sampling. Survey design, sampling protocols…
This paper summarizes the results of krill demographic studies from the Commission for the Conservation of … Antarctic Marine Living Resources 2000 Survey—a large-scale krill survey across the Scotia Sea conducted in January/ … February 2000.
Vessels from Japan, Peru, and the USA conducted four sequential surveys designed to estimate the biomass density … and demography of Antarctic krill in the vicinity of the South Shetland Islands between late December 1999 and early … March 2000.
Salp abundance and length frequency were measured during the large-scale CCAMLR 2000 Survey conducted in the … Atlantic Sector of the Southern Ocean in the 1999/2000 season. Results from regional surveys around Elephant Island … in 1994/95 and 1996/97 seasons also were examined.
