Abstract
A new sustainable technique called Biofloc has lot of potential for the production of fish. With an expanding worldwide population comes a greater need for aquatic food, thus aquaculture is escalating much more quickly to meet this demand. Biofloc is a zero-water exchange, eco-friendly system that enhances water quality and the bio-flocculants act as feed. But the major problem with biofloc is the increasing total suspended solid and organic load with increasing duration which not only deteriorates water quality but also causes mortality. Therefore, there’s an urgent need for sustainable utilization of these accumulated substances. A solution to this is the integration of biofloc and IMTA. In this integration, the accumulated TSS and organic waste can be used as feed by another organism. This integration can also improve sustainability by reducing the effluents released into the environment and bringing economic diversity by producing other value-added species and thereby increasing yield.
