The nilotic tilapia fingerlings were reared at the Miraflores Agricultural Center, 3000 tilapia units were raised, these in a general pond and then they were distributed in three ponds, making a total of 1 000 tilapia per ponds, the stocking density was 4 tilapias / m2. The food was based on a commercial product whose diet was twice a day, this was for all treatments. A completely randomized design was used, the duration of the experiment was 120 days, the treatments were as follows; Pond 1 (control), Pond 2 (EM in water), Pond 3 (EM in food), the feeding was based on a commercial product, in the case of Pond 3, the commercial product plus EM were added. 5% of the pond population was evaluated, which are 50 tilapia, the biomass and feed conversion evaluations were made weekly, having 16 evaluations. The results were analyzed in each variable using the test of means and standard deviation, variance. The water quality in ponds 1 and 2 was improved with the use of efficient microorganisms, taking into account the best parameter in turbidity, dissolved oxygen, pH and ammonia reduction. The use of the water resource in ponds 2 and 3 was greater, which gave us superior parameters to the pond. The use of efficient microorganisms (EM) reduced pathogenic microorganisms by up to 88% in pond 2 and by 53% in pond 3.
