    Abstract

    This document summarizes the current and ongoing development of the revised approach to the management of the Antarctic krill fishery. The revised approach was adopted by CCAMLR in 2019 and integrates three components, namely regular updates of biomass estimates, a population projection model to estimate precautionary harvest rates, and a krill-predator spatial overlap analysis to determine the spatial and seasonal allocation of catch limits.
