The objective of this research was to evaluate the effect of three diets on the survival of post larvae of gamitana and paco. The biological raw material that was used were larvae of 2 native species (gamitana, Colossoma macropomun and paco, Piaractus brachypomus), obtained at the aquaculture center, the "Gran Paso" is located in the Morales district. Three types of food were used: Artemia (Breeze Aqua), imported from U.S.A., with 55% protein; live food (rotifers, cladocerans, copepods, etc.), which were produced at the Gran Paso aquaculture center and artificial feed of 45% protein powder, which was purchased at Jr. Andrés Avelino Cáceres No. 351. The treatments were Artemia 14300 Nauplio / L (T1), live food produced in troughs of 250 liters in concentration of 30,000 zoop / L (T2) and commercial feed with 45% of proteins (T3). The post larvae were fed four times a day, for a period of 10 days. Likewise, 9 incubators of 60 liters of useful volume were used, with a density of 30 post Larvae / L, of three replicates per treatment in a completely randomized design. For post-larvae of gamitana, the commercial food had a lower survival percentage of post larvae, 25%; followed by Plankton, 47%, while brine shrimp was the one with the highest percentage of survival, these percentages being respectively 87.53%; 93.97% and 96.57%. While for the paco species these percentages were respectively 87.73%; 96.83% and 98.22%. The napplios of Artemia sp. were the best food for post larvae of C. macropomun and P. brachypomus at the beginning of their feeding, because they had a higher percentage of survival. However, feeding with natural zooplankton is recommended, eliminating carnivorous copepods in wild zooplankton. Also, the commercial concentrate of 45% protein was not favorable at the beginning of the feeding.
