Biofloc Technology (BFT) apply for aquaculture which is considered towards new biotechnological approaches. To carry out Biofloc technology for intensive culture white shrimp, technology solutions need is calculate the ratio carbon/nitrogen (C/N) , in oder to have enough substance for microorganisms transformed into biomass. Experiments C/N ratio at three treatments C/N = 10, C/N = 12 and C/N = 20. Assessing thought the quality water tank experiments, parameters Biofloc (FVI, VSS, TSS), survival and growth of shrimp. The ratio of C/N = 12 were selected applications in Biofloc technology intensive culture white shrimp (Litopenaeus vannamei).
