What is Bio Floc Technology?
The Biofloc technology is an intensive aquaculture system, in which Biofloc or bacterial floc is introduced into reinforced Geomembrane lined aquaculture ponds, which convert the waste eliminated by aquatic creatures into edible mass. This edible mass is rich in protein (50 to 65 % on dry matter basis), vitamins, and micronutrients and also has probiotic effect. It improves the immune system of the aquatic animal. Usually in the traditional system, feed requirement is approx. 1.5 Kg per Kg of biomass. In Biofloc system due to recycling process of metabolic waste, there is 30 % saving of feed. In traditional aquaculture systems, water exchange is required frequently, resulting in wastage of water and larger expenses. Biofloc significantly reduces the need to exchange water. Probiotic organisms like Bacillus, yeast etc. can be added to the pond water and feed to improve the immune system of the cultured animal. Bacillus licheniformis is able to inhibit the growth of pathogenic Vibrio species.
