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.
