Abstract: The mean goal of this study was to evaluate the effect of rice bran, molasses, and coffee waste in nutritional composition of floccules, and associated micro fauna. Each treatment was made by triplicate in 80L plastic containers with 15 tilapias each one. Parameters like temperature, pH, dissolved oxygen, NO2-, NO3-, and TAN were monitored. Associated micro fauna was estimated by direct count method and proximal analysis was made by standardized methods of AOAC. The results did not show significant differences with respect water quality during all experiment. The associated micro fauna was represented by microalgae, protozoa, and rotifers. Proximal analysis did not show significant differences with respect crude lipids, with relation crude fiber, coffee waste treatment obtained highest percentage (29%), for ashes, molasses obtained the highest value (16.46%), rice bran treatments and molasses showed high protein levels (47,99 and 42.01% respectively). The results indicate that regardless of the carbon source used, the Biofloc contributes as a source of food in situ, which can be comparable with conventional food but without the economic impacts that this generate.
