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 ...

Successful ecosystem-based management of Antarctic krill should address uncertainties in krill recruitment, behaviour and ecological adaptation
Abstract: Antarctic krill, Euphausia superba, supports a valuable commercial fishery ... in the Southwest Atlantic, which holds the highest krill densities and is warming rapidly. The krill catch ... , with the main goal of safeguarding the large populations of krill dependent predators. Here we show ... that, because of the restricted distribution of successfully spawning krill and high inter-annual variability ...
