From October to December 2024, WorldFish researchers conducted a comprehensive post-harvest fish loss assessment in the ‘Dagaa’ fish value chain, spanning from Tumbuju in Mafia Island, Tanzania, to Lubumbashi in the Democratic Republic of Congo (DRC). ‘Dagaa’, a small pelagic fish, is an affordable protein source for the people in East and Central Africa, playing a significant role in the region's food, nutrition, and income security.
