“…Moreover, bioflocs are considered good quality sources of protein that can be used as a feed for tilapia and provide about 50% of its protein requirement [63,64]. Even though the possibility of using bioflocs meal as an alternative source of animal protein source, protein from bioflocs should only be used as a supplementation for dietary proteins [16]. The positive effect of the freeze-drying method on protein content in bioflocs may be due to the benefit of using a freeze-dryer to dry sensitive microbial samples without lessening their protein content [65].…”

“…Bioflocs can be collected from biofloc technology (BFT) system as a wet meal to culture animals [11,12] or as a dried meal after drying processes with high protein levels [13][14][15]. BFT system has many benefits to increase the profitability of the aquaculture industry and also support the sustainability of this sector [16]. In that sense, BFT can keep land and water resources used for fish farming and reduce the environmental impact of aquaculture activities on external water bodies [17][18][19].…”

“…Bioflocs can be successfully consumed by herbivorous and omnivorous fish species [16]. Fish consumption of bioflocs depends on various factors such as the feeding habit of the species and its ability to eat the flakes and suspended particles density [21].…”

Supplementation of dried bioflocs for red hybrid tilapia (Oreochromis sp.) was examined during 57 days of feeding trials. Five experimental treatments; T1 (the control; without bioflocs), T2 (4% freeze-dried bioflocs), T3 (16% freeze-dried bioflocs), T4 (4% oven-dried bioflocs), and T5 (16% oven-dried bioflocs) were prepared to examine the water quality, growth performance and body composition of red hybrid tilapia. T2 and T4 treatments resulted in a higher growth rate and survival similar to the control, while T3 and T5 treatments showed the lowest values of growth performance among all treatments. T1 treatment showed the best quality of culture water followed by T2 and T4 treatments, while T3 treatment resulted in poor water quality followed by T5 treatment. Based on these results, the ratios of bioflocs (4% and 16%) had more effect on fish growth and water quality than the drying methods (freeze-drying and oven-drying). The ratio of 4% freeze-dried or oven-dried bioflocs provided higher growth rates and better water quality parameters similar to the control, while the ratio of 16% showed the worst growth performance and water quality in the present study. In addition, body compositions of tilapia fed 4% dried bioflocs showed better nutritional value than tilapia fed 16% dried bioflocs. Protein and energy levels showed an increasing trend with decreasing supplement levels of bioflocs. Moisture content was significantly higher when supplementation of 16% bioflocs was used. Overall, supplementation of 4% freeze-dried or oven-dried bioflocs can be successively included in red hybrid tilapia diets without any effects on growth or body composition and can result in a good quality of culture water for red hybrid tilapia.

“…Disproportions in the carbon-to-nitrogen ratio can result in problems such as excessive growth of floc and instability in the system. The requirement for elevated water temperature by the bacteria in biofloc systems can provide a constraint, particularly in regions with unstable power sources [62]. Effective management and monitoring are essential for maintaining the ecological balance of biofloc systems, posing a challenge for certain farmers.…”

Biofloc technology (BFT) is an innovative approach in aquaculture that provides substantial advantages for the implementation of sustainable and efficient aquaculture techniques. BFT entails the careful management of water quality and the provision of nutrients to cultivated aquatic organisms by adding carbon sources in a balanced manner. This supports the formation of advantageous microbial communities. The biofloc is an assemblage of organic material and microbes that is abundant in proteins. It functions as a natural source of food for species such as tilapia and prawns, hence decreasing the reliance on costly commercial feeds. This self-contained system aids in water conservation, fertiliser recycling, and waste and pollution reduction in comparison to traditional aquaculture methods. BFT additionally boosts the immune system of aquatic species, diminishing the likelihood of prevalent illnesses and fostering overall well-being. Nevertheless, the technology necessitates meticulous control of variables like as carbon-to-nitrogen ratio, water temperature, and dissolved oxygen in order to uphold a stable and fruitful environment. Although there are certain operational difficulties, BFT proves to be a viable approach for attaining sustainable aquaculture by enhancing output while minimising the negative effects on the environment.
