The growth of tilapia variety Stirling was evaluated during the development stage, from supply of two diets: commercial food and diet based on meat meal. The work was done under a system of semi- intensive production on two concrete ponds with a capacity of 24 m 3 (3x8x1), under an experimental density of 600 fish / pond and for three months (November, December and January). The fishes were fed their body taking into account biomass. Data were analyzed with a factorial completely randomized design with 60 repetitions per treatment. The results showed significant differences for both diets, weight gain was higher with the commercial concentrate (49.65g) with the elaborate diet (25.62g). The commercial diet allows significant growth for Tilapia. The diet of meat meal minimizes production costs, The results indicate that the diet of meat meal has a difference in cost of 66.36%. If required to obtain a commercial weight tilapia,> 350g in a short time, the best option is the commercial concentrate feed, feed costs recovers sales. The diet based on meat meal is an alternative to a producer of low-income subsistence, with sales to the local market and with more time feeds to grow tilapia.
