    Spatial scale is the common ground of all of the three components (Biomass estimation, stock assessment and risk assessment) for the new krill management strategy. The pros and cons of the potential choices of biomass estimate at various spatial scales were discussed to facilitate the deliberation on Krill Stock Assessment at the WG-SAM-2021 meeting. Considerations were also given on the spatial scale that is appropriate both for acoustic biomass estimation and stock assessment, and on the pragmatic approach to implement the new krill management strategy in an efficient manner. Discussions were focused on the work in Subarea 48.1, but some of these considerations may also be applicable in other Subareas.
