Modelling growth and reproduction of Antarctic krill: implications of spatial and temporal trends in temperature and food for ecosystem-based management of krill fisheries
Abstract: Errors in the growth model used in stock assessments of Antarctic krill, specifically ... higher rates of growth than occur in reality, could inadvertantly lead to over-exploitation of the krill ... generally applied under spatially and temporally varying conditions. In the context of assessments of ... precautionary yield for krill in CCAMLR, we recommend that this new model be incorporated into those assessments ...
