This report from the UK Changing Markets Foundation investigates the impacts of krill fishing in the Antarctic. Krill - tiny crustaceans that are near the base of many marine food chains - are caught for use in omega-3 dietary supplements and as feed for aquaculture. In light of krill fish’s impacts on fragile ecosystems, the report calls for an immediate moratorium on krill fishing; for retailers to phase out the use of wild-caught fish, including krill, for aquaculture; for retailers to stop selling krill dietary supplements; and for consumers to stop using krill supplements and to demand krill-free seafood.

This paper reviews the development of the global aquaculture sector between 1997 and 2017. It finds that while the feed efficiency of aquaculture has improved, aquaculture remains strongly dependent on marine feed ingredients. It identifies strong potential for cultured molluscs and seaweed to contribute to both nutritional security and ecosystems services.
