Biofloc technology (BFT) application offers benefits in improving aquaculture production that could contribute to the achievement of sustainable development goals. This technology could result in higher productivity with less impact to the environment. Furthermore, biofloc systems may be developed and performed in integration with other food production, thus promoting productive integrated syst...

The aim of this study was to assess the relative contribution of natural productivity and compound food to the growth of the juvenile blue shrimp Litopenaeus stylirostris reared in a biofloc system. Two experiments were carried out based on the same protocol with three treatments: clear water with experimental diet (CW), biofloc with experimental diet (BF) and biofloc unfed (BU). Shrimp surviva...

background: biofloc technology is considered  a method that degrades organic waste by microorganisms and produces bacterial flocculation. objectives: this study was performed to evaluate of the application of biofloc technology in therearing of common carp (cyprinus carpio) fingerlings in intensive culture. methods: the experiment was designed in four treatments (commercial diet as a control, 7...

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 animal...

A bioflocculant-producing bacterium, Bacillus megaterium SP1, was isolated from biofloc in pond water and identified by using both 16S rDNA sequencing analysis and a Biolog GEN III MicroStation System. The optimal carbon and nitrogen sources for Bacillus megaterium SP1 were 20 g L-1 of glucose and 0.5 g L-1 of beef extract at 30°C and pH 7. The bioflocculant produced by strain SP1 under optimal...

The objective of this study was to document the immunological effects of growing shrimp in biofloc systems. The experiment consisted of four types of biofloc systems in which bioflocs were produced by daily supplementation of four different carbon sources, i.e. molasses, tapioca, tapioca-by-product, and rice bran, at an estimated C/N ratio of 15 and a control system without any organic carbon a...

The present study was conducted to determine the appropriate level of protein in diet of Cyprinus carpio fry based on biofloc technology. The experiment was designed based on triplicate of four bioflocs treatments (BFT) and one control treatment (CW). 450 specimens of C. carpio fry with mean weight of 17±0.08 g were stocked in 15 fiberglass tanks. Fish were fed in biofloc treatments with diets ...

Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...
