Application of Biofloc technology in aquaculture with an emphasis on ornamental fish

Biofloc technology (BFT) is a relatively new biotechnological means to support high density culture, maintain water quality, biosecurity, reduce the need for water exchange, reutilize the feed and reduce the production cost. This technology is mainly based on the principle of waste nutrients recycling (particularly nitrogen) into microbial biomass that can be used in situ by the cultured animals. In ornamental fish culture, rearing of larvae are the difficult-phase where the commercial ornamental fish farmer face a lot of difficulties due to low survival rate, water quality management and incidence of disease, these problems could be easily averted through Biofloc technology. Biofloc system is a new alternative that can be used in the culture of different ornamental species produced in country, if the nutritional requirements for each species are considered. In this review study, we will discuss on biofloc technology in Aquaculture with an emphasis on ornamental fish.
