The aim of this study is evaluating the performance of Tilapia-do-nilo (Oreochromis niloticus) fingerlings (GIFT lineage) fed with a diet containing dehydrated fish protein (DPP) and commercial feed (RC) during the early stage of development. Dehydrated fish protein was produced from tilapia fillet residues and contains approximately 35% crude protein. After 69 days of cultivation, fingerlings fed with DPP diet had a body weight gain of 77,5g and an average alimentary cost of R$ 2.21 per kg of fish produced. The fish that consumed commercial feed grew 88,6g at an alimentary cost of R$5.33kg-1. In sum, the new DPP ingredient and its nutrients not only meet the nutritional needs of tilapia fingerlings in the early stage of development, but also lowering fish feeding cost and enhancing the value aggregation to the fishery activity.
