Discussion on recent results from an integrated assessment of Antarctic krill (Euphausia superba) in Subarea 48.1
-assessment framework for Antarctic krill (Euphausia superba) to assimilate multiple sources of survey data ... from three of the models provide a robust picture of changes in the krill population. An annual model ... . Differences in scaling of biomass estimates between the annual models and the more highly resolved models ... estimates of biomass (rather than relative estimates of biomass) may therefore be biased, possibly leading ...
