    Abstract

    A standardized krill net sampling survey was conducted in the Lazarev Sea (CCAMLR Subarea 48.6) in austral summer during December/January 2007/08 (LAKRIS, Lazarev Krill Study) as a German contribution to CCAMLR-IPY 2008. At the start of the survey period the entire survey area was completely covered with seasonal pack-ice, but rapidly retreating until the end of the survey in late January. 52 samples were taken by RMT 8 and RMT 1 along three transects south of 60°S. Krill and other Antarctic Euphausiacea species densities were estimated from both RMT net samples. Length and maturity stage composition and seasonal development of maturity stages were analysed. Distribution and density of krill larvae are provided for the Lazarev Sea.
