Biofloc Fish Farming
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.
BioFloc fish Farming
It is an innovative and cost-effective technology in which toxic materials to the fish and shellfish such as Nitrate, Nitrite, Ammonia can be converted to useful product, ie. Proteinaceous feed. It is the technology used in aquaculture system with limited or zero water exchange under high stocking density, strong aeration and biota formed by biofloc.The culture of biofloc will be productive in the case of culture tanks exposed to sun
Planning & Strategies
Biofloc system was developed to improve the environmental control over the aquatic animal production. In aquaculture, the strong influential factors are the feed cost (accounting to 60% of the total production cost) and most limiting factor is the water/land availability.
Benefits
Reduces water pollution and the risk of introduction and spread of pathogens
Cost-effective feed production.
It reduces utilization of protein rich feed and cost of standard feed.
Planning & Strategies
High stocking density and rearing of aquatic animals requires wastewater treatment. Biofloc system is a wastewater treatment which has gained vital importance as an approach in aquaculture.
Benefits
It reduces the pressure on capture fisheries ie., use of cheaper food fish and trash fish for fish feed formulation.
Higher productivity (It enhances survival rate, growth performance, feed conversion in the culture systems of fish).
