| Table 3: Chemical and physical characteristics of water (mean ± standard deviation) during the experimental cultivation of super intensive marine shrimp, Litopenaeus
vannamei with bioflocs with application of microbial bioremediation (Comambio®) and without bioremediation (Control). The data on weeks zero (0) correspond to analysis
performed in the two treatments at the beginning of the experiment. |
