Fisheries are an important source of food, income and nutrition in Tanzania, where 25% of the country's population depends on coastal resources or inland lakes for their livelihoods. Over 180,000 people are employed in the fisheries sector, with a further 19,223 people involved in fish farming. WorldFish is working with the Tanzanian government and development partners to increase aquaculture production, reduce postharvest fish losses and enhance the role of fish in nutrition. WorldFish, one of the few organizations doing aquaculture and fisheries research in Tanzania, will deliver this work by drawing on its strong networks with national and regional fisheries organizations such as the Tanzania Fisheries Research Institute (TAFIRI), University of Dar es Salaam, Lake Tanganyika Authority (LTA) and Lake Victoria Fisheries Organization (LVFO).
