EU-funded AQUAEXCEL3.0 aims to further boost the European aquaculture sector, building on previous AQUAEXCEL and AQUAEXCEL2020 projects. Integrating 40 top-class research facilities from biology to technology in all types of rearing systems, and covering all major EU farmed species and promising new species, it will expand access to high-quality services and resources. Through a strong partnership, the project will boost excellent research and sustainable innovation for both public and private sectors working in aquaculture. The 3Rs (reduction, refinement and replacement) are key to this project, which will provide research and industry with new services focused on their needs. The enhanced scope includes shellfish, macroalgae and recyclers (insects, marine worms) to move towards a more sustainable and circular aquaculture.
