Bio-Floc Fish Farming

Biofloc technology (BFT) is a related between new and potentially revolutionary organism that is especially productive for aquaculture.It is sustainable and environmentally-friendly process of aquaculture that controls water quality and harmful pathogens along with providing value-added creation of the microbial protein feed for the aquatic farm structure.High-density rearing of fish generally requires some waste management infrastructure.Biofloc systems were developed to prevent the introduction of disease to a farm from incoming water.

The nutritional quality of Biofloc system of cultured animals is good but rather variable. The dry-weight protein content of Biofloc ranges from 25 - 50 percent,with most estimates between 30 and 45 percent. Fat content ranges from 0.5 - 1.5 percent,with most estimates between 1 and 5 percent. There are conflicting report about the adequacy of Bioflocs to give the often limiting amino acids methionine and lysine.

Bioflocs are good sources of vitamins and minerals,Particularly phosphorous.Bioflocs may have probiotic effects.
