    This paper describes distribution and size-age composition of Antarctic krill (Euphausia superba) in commercial catches by Russian trawler 'Maxim Starostin' in the South Orkney region (Subarea 48.2). The fishery operations were conducted between January and March in 2008/2009 and 2009/2010 seasons. All age cohorts of krill passed spawning during the season 2008/2009, while in anomalous cold 2009/2010 season significant proportion of krill of cohort 2+ skipped spawning. Individuals of Antarctic krill in age 1+ were absent in catches in both 2008/2009 and 2009/2010 seasons. Possible reasons of this phenomenon are discussed.
