The prospects of biofloc technology (BFT) for sustainable aquaculture development

As capture fishery sector continues to decline, aquaculture industry must be accelerated to bridge the fish supply gap especially in the developing countries. However, in most developing countries, aquaculture sector is characterized by low productivity due to inefficient technologies, hence the nee...

BFT is useful for mass production of live food resources, which are indispensable for successful larviculture in hatcheries. Bioflocs enhance gonad formation and ovary development in fish broodstock, thus improving reproduction of fish. Bioflocs are also natural biosecurity agents that reduce the use of antibiotics, which have various ecological consequences in aquaculture environment.
