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 |
