Ingrid Undeland, Professor of Food Science at Chalmers University of Technology and coordinator of the RE-BLUE project, makes the case for herring and sprat as next-generation food sources. Despite dominating fisheries across Northern and Central Europe and ranking among the most nutritionally and climatically favourable animal proteins in the EU, the vast majority of their catches still go to animal feed. The REBLUE project is developing scalable food value chains to change that.

Neil Duncan from IRTA (Spain's Institute of Agrifood Research and Technology) also tells us more about BLUEBOOST Project, a research project testing whether farming fish and shellfish together with species that need little or no feed, such as seaweed, mussels and oysters, can produce more seafood and a wider variety of it with a smaller environmental footprint. The idea is that waste from traditionally farmed species becomes food and nutrients for these lower-input species, cutting pollution and making better use of resources.
