This study evaluated the feasibility of using Comambio®, commercial product for bioremediation, in superintensive system of Litopenaeus. vannamei with zero water exchange. First, the concentration was determined to bioaugmentation on the settleable solids (SSed) in water containing microbial flakes. The second stage consisted in testing the application frequency in weekly and biweekly basis upon performance of shrimp. Were described physical and chemical parameters of water quality in the treated trial and that without application. The concentration of 0.56 g/L was selected by reducing significantly (p<0.05) the SSed value. The frequency of weekly application promoted the chance of livelihood and increased the final biomass growth of the shrimp by 46.6% of growth rate, 17.0% in the final biomass and 10.23% of livelihood with regard to the contr..
