    Current Antarctic krill fishing practices have been deviating from historical fishing patterns, with catches concentrated recently in certain areas such as Subarea 48.1. Based on sea-ice reduction projections, concentrated catches in Subarea 48.1 during winter are expected to occur more frequently. The reproduction and survival of krill are significantly affected by sea ice cover. This is of concern since key spawning, recruitment and nursery areas of krill are located in the Southwest Atlantic sector, an area that has been warming rapidly, resulting in a reduction in the extent and duration of winter sea ice.
    CCAMLR needs to maintain a precautionary approach to krill fisheries management. The establishment of CM 51-07 – distributing the trigger limit among statistical subareas – was a step in the right direction. CCAMLR should retain CM 51-07 to avoid concentrating the catch in one sub-area as the trigger level is approached, reducing the risk of localized depletion of krill near predator colonies. Although the two-year experimental design of scientific observation produced positive results, it seems that sufficient observer data will not be obtained to allow the CCAMLR Scientific Committee to provide advice to the Commission. Thus, CCAMLR should persist in its efforts to work toward 100% observer coverage across all vessels in the krill fishery as the best way to achieve systematic observer coverage. The review of CEMP has become a high priority for the Working Group on Ecosystem Management and Monitoring. An expanded and reformulated CEMP will require new sources of funding and thus, CCAMLR will need to develop funding mechanisms, such as a dedicated CEMP Fund, to ensure the necessary resources are available. Uncertainties over green weight, krill escape mortality and the impacts of krill fishing on fish larvae continue to be a reason for concern.
