This brief summarizes WorldFish’s work on fish-based products in seven countries across three continents over the past 10 years. It is based on an e-learning event that brought country teams together to document approaches, lessons and research priorities. Fish-based products are a cornerstone of WorldFish’s work. Piloting and/or scaling products such as dried fish and fish powder have been a core component of its aquatic food system research for development and nutrition-sensitive programs, providing a link between production systems and consumer well-being.
