It is estimated that small-scale fish processors in Tanzania lose up to 40% of the fish harvest due to poor postharvest fish processing infrastructure, particularly a lack of cold storage and drying facilities to limit fish spoilage. Uncontrolled postharvest fish loss leads to income loss, keeping small-scale fishers in the poverty cycle. At MAVUNOLAB, we help fish processors in Lake Victoria, western Tanzania, avoid fish loss and spoilage by deploying low-cost Solar Drying Facilities developed by MAVUNOLAB.
