Biofloc Fish Farming System

Biofloc Fish Farming System

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.

What Biofloc Systems do?

Biofloc provide two critical services that are treating wastes from feeding and providing nutrition from floc consumption.Biofloc systems can work with low water exchange rates (0.5 to 1 percent per day). This long water residence time allows the development of a dense and active Biofloc technology profitability and business sustainability. However, the value of flocs in nutrition is limited at the highest levels of production intensity since the contribution of feed to the growth of cultured animals is overwhelming.
