The number of freshwater fish breeders are now demanding the breeder to produce maximum outputby considering variables such as amount of food, water flow and a tank?s wide and thus require an appropriate system to predict future harvests. Applications to apply fuzzy logic is one solution to help the breeders to predict the outcome of freshwater fish breeding. The first step to predict the outcome of freshwater fish production using Mamdani method is determining the input and output variables that are set firmly. Then change the input variable into fuzzy sets with fuzzification process. In the case study discussed in this paper defuzzyfication process using Centroid method that asserts fuzzy in which the pullout solution is obtained by taking the center point of a fuzzy area. The accuracy of results in the studies conducted, it can be seen that the accuracy ofprediction output by the system built is 92\% compared with the results of calculations performed using matlab. Furthermore, the results of breeding prediction can be used as an overview for breeders to determine harvest in the future.} }
