Bio-floc system is a cost-effective method of aquaculture. It has become very popular all around the word as an alternative to pond aquaculture.

Because nutrients may be continually recycled and reused in the culture medium with minimal or no water exchange, BFT is considered the new “blue revolution.” Bio-floc technology (BFT) is an aquaculture system based on in situ microorganism generation that is environmentally benign. Bio-floc is a type of pond growth made up of aggregates of living and dead particle organic matter, phytoplankton, bacteria, and bacteria grazers. It involves the use of microbial processes within the tank/pond to offer food resources for culture organisms while also acting as a water treatment tank. As a result, this system is sometimes referred to as an active suspension pond.

BIO–FLOC’S COMPOSITION AND NUTRITIONAL VALUE:
Bio-floc system is an extracellular polymeric material containing a heterogeneous aggregate of suspended particles and a diversity of microorganisms.

It is made up of bacteria, algae, fungi, invertebrates, and detritus, among other microorganisms. 

It’s a protein-rich live feed created when wasted feed and excreta are converted into natural food in a culture system after being exposed to sunlight. 

Each floc is held together by a loose loose mucus matrix produced by bacteria and held together by filamentous microorganisms or electrostatic attraction. Large flocs are visible to the human eye, but the majority are tiny. The size of the flocs ranges from 50 to 200.

Bio-floc system is a Profitable Fish Farming Method. It has gained a lot of traction as a viable alternative to open-pond fish farming all over the world. It is a low-cost method of converting hazardous compounds
