    Abstract

    A standardized krill net sampling survey was conducted in the Lazarev Sea (Subarea 48.6) in December 2005. Krill densities were low in the Lazarev Sea. No substantial day/night differences were observed in the catches. Spatial distribution of krill density and size/age classes is discussed for the Lazarev Sea. Recruitment indices were calculated for one-year-old (R1) and two-year-old krill (R2), showing high values for both recruitment indices. New information is given on the development of maturity stages in the early phase of the spawning season.
