This study was conducted in the facilities of the company for exporting ornamental fish: Nautilus Export SAC, in Loreto - Perú. For 15 days we evaluated the growth and survival of postlarvae of red-tail sábalo (B. cephalus) grown in three water flows (0.5, 1.0 and 1.5 l/min) and three densities (10, 20 and 30 postlarvae / l). were stocked 4320 postlarvae in 27 tanks (30x20x20cm). The first five days were fed with 200 moinas / postlarvae, and the remaining ten days with a pulverized diet of 50% crude protein, with a feed rate of 10% of the biomass, were fed three times a day (8:00, 11: 00 and 14:00 hours). Every 5 days growth in length (mm) and survival (%). was evaluated. Water quality was monitored daily (temperature, dissolved oxygen, pH, and CO2) and every three days alkalinity, nitrite and ammonia. Growth and survival were analyzed with Two-Way Variance (ANOVA) using SPSS 18. At the end of the experiment there were no significant differences in growth and survival in post-larvae of red tail sábalo, using three water flows, but, for stocking densities, been the density of 30 post-larvae/l which scored highest growth in average daily gain of 1.16 and 24.91 mm overall length. However, the density of 10 post-larvae / l, achieved better results in survival of 17.92% in comparison with the other two densities. Physical and chemical parameters of the water quality were considered satisfactory for growing post-larvae. In survival, there were found significant differences (P <0.05), it is concluded that the density of 10 post-larvae/l, can become an alternative to be used on the release of post-larvae to fingerling.
