The total stratified bottom trawl abundance index is of same magnitude as the acoustic abundance estimate, but the acoustic survey indicate relatively higher

Annual acoustic trawl surveys for krill monitoring have been carried out by the Institute of Marine research, Norway near the South Orkney Islands since 2011.. The survey has
