The Norwegian government has launched missions under their long-term policy priorities where research-based knowledge and skills are regarded prerequisite for achieving the concrete goals. The mission on sustainable feed sets the objective of ensuring that all feed for farmed fish and livestock shall come from renewable sources, thus reducing greenhouse gas emissions from food systems. Today, less than 10% of the feed for fish farming is from Norwegian sources. The mission also suggests increasing security of supply by develop a stronger feed ingredients industry in Norway. The aquaculture industry conveys that the prospected future production growth depends on increase in novel feed raw materials. Various assessments of potential sources of feed raw material hold benthic filter feeders (bivalves, blue mussels, tunicates) as primary candidates, with their nutrient qualities, production potential and relatively low environmental footprint. We will address the potential for production, some prospects for industry development and the main challenges for realizing the scale of production needed for contributing as a feed ingredient.
