The performance of Nile tilapia fed with bran made of pequi peel was evaluated. Two hundred fingerlings, at 37 days of age and with mean body weight of 0.63±0.25 g, were distributed in a completely randomized design with four treatments 0, 20, 40 and 60% of replacement of commercial diet with bran made of pequi peel with five repetitions represented by boxes of polyvinyl chloride (PVC) with capacity for 130 L, with 10 fish each, totalizing 20 experimental units. The performance characteristics evaluated were feed intake, body weight, weight gain, feed conversion, total length, and live viability. Feed conversion 1.96µ; 2.21µ; 2.63µ; 3.12µ increased linearly with the inclusion of bran made of pequi peel, while the other performance variables were not influenced by treatments. The conclusion is that the inclusion of bran peel in the pequi diet worsened feed conversion, without changing other performance variables.
