1. 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 ... population and cause impacts on krill predators.  We review the three classes of models available for ... modelling krill growth – the von Bertalanffy class, the moult-cycle class based on measures of the duration ...
