The dependence on fish meal and oil obtained from wild fisheries raises serious risks to the development of aquaculture. Alternative raw materials are sought to minimise this threat. For years, agricultural products such as soya in a primary role and pea, faba bean or lupin in secondary role support this effort. Increasing their use remains a challenge that can offer European farmers a potentially high-value market for grain legumes. This note sets out the quality requirements of grain legumes for fish feed. The purpose is to support farmers and grain traders who wish to supply to this market.
