We used 80 fingerlings of tilapia (Oreochromis<br />niloticus) masculinized with initial weight of 0.11 ± 0.03 g, distributed in 20 aquariums of 15L of water in<br />a completely randomized design with four treatments and five replications in a recirculation system<br />water with constant aeration. The diets were prepared with commercial ration mashed with the<br />addition of (0, 0.50, 1.00 and 1.50%) of residue. The variables studied were: ultimate weight (UW),<br />Weight gain (WG), Whole-length (WL), Standard length (SL), Length of head (LH), Index profile (IP),<br />Index head (IH), Condition factor (CF), Width and Height. There was no positive effect (P&lt;0.05) of<br />the use of red propolis residue on the productive performance of animals. ER -
