    Abstract

    As part of the revision of the krill management approach, an updated set of parameter values is required for the Grym to perform projections in Subareas 48.1, 48.2 and 48.3. Where applicable, Subarea-specific values are set to account for the different dynamics in each Subarea. Given the scope of the task, some parameter values are found in the scientific literature while others correspond to the current expertise from all involved CCAMLR scientists. This document summarizes discussions held in the "GYM/Grym assessment model development” e-group.
