In the present study, the efficiency of the microalgae Scenedesmus sp. and Pinnularia sp. as a supplement in the diet of tilapia was tested in the growth in size and weight of Pargo tilapia, UNAM, cultured in a Biofloc in 250 L containers, in a period of 120 days. Survival of the organisms in the three treatments ranged from 80-85%. Organisms in the 10 cells x 106 treatment obtained the highest weight with 598±0.60 g, although the highest length gain was found in the control treatment with 41.06 cm. The AGR for weight was higher in the 10 cells x 106 treatment with 4.74 g day-1, while the highest IGR for length was presented in the control treatment with a 0.33% daily increase. For length, the highest AGR was for the 10 cells x 106 treatment with 4.58 g day-1 and the IGR was for the 2.5 cell x 106 treatment with 2.59% daily increment. Both FCF and FCE were for the 10 cells x 106 treatment with 0.247 and 404.5%, respectively. The incorporation of microalgae into the system provides nutrients that the Biofloc and bacterial biomass do not incorporate in the diet of the organisms.
