Abstract

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 control sample. Eventually, there was a dramatic drop in the SSed (63.4%) with Comambio® while the total suspended solids increased with the suspended fixed solids. On the other hand, the biochemical oxygen demand showed the least value, Comambio® and control, 70.2% and 17.4% respectively. Summing up the bioaugmentation agent declined the value of SSed, contributing to the growth and reducing feed conversion as well as the final livelihood biomass of the shrimp cultivation system. The total average gain in weight per fish was higher in the automatic feeding (89.50 g) than in manual (78.50 g). An FE of 20.9% was obtained in the automatic feeding and 18.6% in manual, in relation to their FCRs. A t-test, conducted at 5% significance level, indicated a significant difference in the two feeding methods
