With the global supply of forage fish at a plateau, fed aquaculture must continue to reduce
dependence on fishmeal and oil in feeds to ensure sustainable sector growth. The use of
novel aquaculture feed ingredients is growing, but their contributions to scalable and
sustainable aquafeed solutions are unclear. Here, we show that global adoption of novel
aquafeeds could substantially reduce aquaculture's forage fish demand by 2030,
maintaining feed efficiencies and omega-3 fatty acid profiles. We combine production data …
