FishEUTrust will establish five Co-creation Living Labs in the Mediterranean Basin, the North Sea and the Atlantic Sea. These will enable innovation and process validation and demonstrate the project's supply chain solutions. Examples of supply-chain innovation include creating sustainable business models, protecting cultural and culinary heritage, short food supply chains, exploiting underused fish species, and innovative engagement activities to stimulate positive consumer behaviour. The project will also develop tools to maximize trust by guaranteeing the quality, safety, and traceability of seafood products based on smart control systems (sensors), metagenomics, genetic biomarkers, isotopic techniques, and labelling/product passport/blockchain). These tools will be integrated into a single digital FishEUTrust data platform.
