    Résumé

    As part of the revision of the krill management approach, the Secretariat was tasked to estimate proportional recruitment indices in Subareas 48.1, 48.2 and 48.3 using the SISO (i.e., observer) krill length data collected onboard fishing vessels. This document summarizes the steps taken to estimate the mean and standard deviation of proportional recruitment in each Subarea, for potential use as inputs to the Grym (Maschette et al., 2020).
