Fish collagen (incl. its partly hydrolyzed product gelatin) has potentially valuable applications in the medicine, food, and pharmaceutical industries. Fish oil is applied for aquaculture, animal, and human consumption as a nutritional supplement and functional food, and in pharmaceuticals. The production and applications of fish collagen and marine oil-based supplements are the main subjects of this unit and it outlines their main valuable characteristics, market positions, barriers, and prospects for their further exploitation. Information about the tunicate Ciona intestinalis and the possible compounds (cellulose, fatty acids, and proteins) that can be isolated and further valorized is also provided.
