Abstract
  • The most known Lake Victoria dagaa fishery (Rastrioneobola argentae) in Eastern and Southern countries of Sub-Saharan African region consists characterized by physical, quality and economical (PQE) losses along the supply chain. The survey was done on the PQE losses on Sun dried dagaa along the supply chain. Losses are at fishing, processing under sun drying on bare open beach sand and during consumers' preparation. During sun drying in open sand, birds and animals find an opportunity to eat. If it rains then there is a total physical loss. Similarly economical loss is in parallel due to poor raw dagaa and sand processed dagaa products which lead to low price of dagaa. The price of dagaa is dependent on the quantity and quality of the dagaa catch yield. Dagaa again suffers with a huge loss about 1/3 of total weight of dagaa during preparation for cooking at street restaurants and households. The heads and bellies of dagaa are removed on believes that heads contain sand and the bellies cause the bitter taste of dagaa.  The consumer encounters loss in quantity, nutrients and economical losses due the sand, heads and bellies parts being removed and thrown away during preparation.  PQE losses are costing all the stakeholders in the supply chain, the fishers, traders, Government and consumers. The dagaa business is not formally regulated; very few traders may declare exports. Hence the government is losing a lot of revenue as there is limited control of records on processed and exported dagaa products.
