Biofloc Technology: An emerging tool for sustainable aquaculture
Author(s): K Suneetha, K Kavitha, Darwin CH
Abstract: As the global population continues to grow, food production industries such as aquaculture will need to develop in a sustainable way. Increasing aquaculture production is limited, because of severe limitations of water and availability of suitable land. To overcome these problems adopting the concepts of recycling and converting the metabolites into efficient feed by zero/minimal water exchange, conserving the water and land with high shrimp/fish production. Hence the best environmentally acceptable “Biofloc Technology” has been developed. Biofloc technology (BFT) has beneficial effects in aquaculture management, including water quality, feeding and disease control. Application of BFT in aquaculture offers a solution to avoid the environmental impact of high nutrient discharges and to reduce the use of artificial feed. In BFT, excess of nutrients in aquaculture systems are converted into microbial biomass, which can be consumed by the cultured animals as a food source. This technology, to a certain extent, has also the capacity to control pathogens in aquaculture. An attempt has been made to summarize the features and management aspects of the environmental friendly biofloc farming system to achieve sustainable aquaculture.
