    Résumé

    Acoustic data on Antarctic krill in Subarea 48.1 are available in several spatial scales that are relevant to the work of WG-ASAM-2021. The various spatial scales (or areas with different size and shape) available from CCAMLR that could be considered by WG-ASAM-2021 to provide biomass estimates of Antarctic krill in Subarea 48.1, together with the US AMLR survey strata and the Chinese fishing vessel survey transects, are presented in a single chart for easy reference. The distribution of krill catches in Subarea 48.1 is also shown to aid consideration in choosing a suitable/practical spatial scale to be used for providing an interim management advice for the Antarctic krill fishery in 2021.
