Abstract

Based on in-situ microorganism generation, biofloc technology is an aquaculture method that is favourable to the environment. The term "biofloc" means the lump of living and dead organic materials, phytoplankton and bacteria that feed on other bacteria that are suspended in water or other bodies of water. Using waste nutrients as fish food is a method of alternative fish farming known as biofloc technology. This analysis focuses on the prerequisites for a biofloc fish farming system, biofloc development, the microbial community, and the significance of microbial interaction in biofloc technology, where phytoplankton and bacterial populations play a more major role in preserving water quality. Between bacteria and algae, there is a complicated relationship. Due to bacteria, Algae can be decomposed into organic nutrients. Along with its ability to distribute bioactive chemicals, biofloc's nutritional value influences the entire aquatic food supply. The control and harmful consequences of nitrogenous chemicals have been covered in this review (such as ammonia, nitrites and nitrates). To create microbial protein from harmful fish waste and other organic debris in the water, Biofloc, or more particularly, cultivated microbes, are added to the water. This lowers costs while also maintaining water quality. Biofloc advantages and disadvantages are also discussed in this review and what improvement can be made to biofloc technology.
