The need to protect young fish and spawning aggregations in fisheries generally, and specifically in the Champsocephalus gunnari fishery in Subarea 48.3, is reviewed. Mechanisms available to achieve these objectives are discussed, including the measures put in place by CCAMLR to date. These measures are re-examined in the light of new information, and a strategy for the future protection of young fish and spawning aggregations of C. gunnari in Subarea 48.3 is considered. This comprises a combination of existing measures, including minimum mesh size and fish size, and a proposed new closed season from 1 March to 31 May.
