Aquaculture Europe 2021, Funchal, Madeira, 4-7 October, One of the main problems associated with any food production value chain is valorisation of by-products and side-streams to reduce the environmental impact, while optimizing the use of resources (Newton et al., 2017). This is especially needed for the aquaculture sector, where circularity principles are key elements to meet sustainability requirements. In the H2020 project “GAIN” , we have used different strategies to address this issue by investigating innovative processes aimed at reusing: fish sludge, generated in Recirculating Aquaculture Systems (RAS), fish mortalities, by-products generated by fish processing (heads, frames and trimmings, skins, etc..), and shells from bivalves generated by the cannery industry. Main results and developments that will significantly contribute to the eco-intensification of this productive sector are presented
