Water Quality Management Using Bioflocs Technology: Catfish Aquaculture (Clarias sp.)

Biofloc technology is one of the alternative to overcome the problem of water quality of cultivation environment which was adapted from conventional waste management techniques. The purpose of this study was to assess the young catfish culture by applying bioflocs of some consortium products, such as Bacillus megaterium (BM), Supernit (SP), Depok 165 (DP165), Kayajaga (KJ) compared to non biofloc application for improving the water quality. The results of this study and statistical test showed that the lowest concentration of TAN by probiotic KJ was about 2.56 mg L-1, while the control was about 5.47 mg L-1, and the consortium of bacteria gave effect to TAN value (p 0.05). The lowest concentration of nitrite by probiotic BM was about 0.065 mg L-1, while the control was about 0.124 mg L-1, and the consortium of bacteria gave effect to the nitrite value (p
