The EU and its Member States are investing in research into organic fish production, which offers a solution for food security in Europe. In this context, the EU-funded EUAqua.Org project will enhance European organic fish production by developing innovative solutions to address critical challenges in farming Atlantic salmon, European sea bass, gilthead sea bream and rainbow trout. The project will advance phenotyping, genotyping, and genomic prediction technologies, providing essential tools for cost-effective and environmentally sustainable organic aquaculture. It will implement a comprehensive communication and training programme to ensure these tools are effectively used in the industry, including a co-developed online training course for stakeholders like breeding companies and fish farmers.
