ABSTRACT
Aquaculture as a food-producing sector is recognized for its ability to contribute to the global fish supply. Aquaculture production is projected to rise to 82 million tonnes in 2050. In biofloc systems, intake of microbial flocs in insitu manner and the supplementation of processed floc as feed ingredient has been evaluated. Owing to the increased demand of seafood for human consumption, the demand for fishmeal and fish oil used for aqua feed production by feed manufacturers also increases. In aquaculture development, green water technology has been adopted with varied perceptions. In contrast to conventional approaches such as antibiotic, antifungal, probiotic and prebiotic application biofloc can be a novel strategy for aquatic health management. In aquaculture to maintain optimum water quality biofloc technology has become a sustainable technique and this can be achieved with the presence of dense heterotrophic bacterial groups with the supplementation of carbon source to the water.
