Biofloc Fish Farming initiative

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 principle of this technique is the generation of nitrogen cycle by maintaining higher C: N ratio through stimulating heterotrophic microbial growth, which assimilates the nitrogenous waste that can be exploited by the cultured spices as a feed. The biofloc technology is not only effective in treating the waste but also grants nutrition to the aquatic animal.

Biofloc Technology (BFT) has been running successfully in counties like Indonesia, Thailand, China etc.

Advantages of Biofloc Technology over conventional pond culture:

Biofloc Technology

Pond Culture

Low Set up cost

High set-up cost

Eco friendly Green Technology

Use of pesticide and artificial hormones

High density culture

Low density culture

7 ~ 8 times more yield compared to pond culture

Low yield

Quantity of feed required 50% Less

Wastage of feed

Controlled environment: Easy to control water parameters (pH, TDS etc.) as culture is done in

Uncontrolled environment: Difficult to control water parameters in open ponds

Low labour cost

Labour intensive leading to high labour cost

Practically no disease in biofloc

Susceptible to disease which is difficult to control

No effect of natural calamities

Susceptible to natural calamities such as floods
