SIPEX_krill

All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    Description

    This work was completed as part of the SIPEX - Sea Ice Physics and Ecosystem eXperiment - voyage. September/October 2007. The work formed part of AAS (ASAC) projects 2337 and 2767.

    Aspects of krill (Euphausia superba), growth and condition during late winter-early spring off East Antarctica (110 - 130 degrees E) were investigated. We assessed diet and condition of larval and postlarval krill collected from open water and below the ice. Condition was assessed using lipid content, growth rates and digestive gland size; feeding history was assessed using fatty acid profiles and stomach content analysis; and a starvation study investigated the response of krill to long-term food deprivation. Potential food items were analysed for lipid and fatty acid composition. Fatty acid profiles and stomach content analysis revealed winter/early spring feeding strategies of both larval and adult krill.
