Abstract

Isoproteic (30% DP) and isoenergetic (3,200 kcal kg-1) diets were formulated using acid silage of shrimp waste as alternative protein source at five levels (0, 4, 8, 12 and 16%). Two hundred fish (7.2 ± 0.5 g) were randomly distributed in 20 tanks of 100 L at a density of 10 fish tank-1 in a closed recirculation water system. The experiment was accomplished in a completely randomized design with 5 treatments and 4 replicates. Growth performance and proximal composition parameters of the muscular tissue were evaluated to tilapia fed three times a day to satiation during sixty days. Quadratic effect (p < 0.05) to weight gain, protein efficiency ratio, specific growth rate, protein retention, and linear effect (p < 0.05) to feed consumption, feed conversion rate and gross lipid in muscular tissue were observed. The acid silage of shrimp L. vannamei waste provide better growth performance, without losses in proximate composition of the muscular tissue, with 2.75% of inclusion in fingerling Nile tilapia diets
