“…Studies have shown that BFT can enhance the nutritional quality, reproductive performance, and early larval development of shrimp and fish [ 165 – 168 ]. Biofloc is a significant source of dietary lipids, including phospholipids and essential fatty acids, that are important for reproduction and embryonic and larval development in various species of aquatic organisms, such as Litopenaeus stylirostris [ 169 ], F. duorarum [ 170 ], L. vannamei [ 170 ], F. brasiliensis [ 171 ], O. niloticus [ 168 , 172 ], C. carpio [ 173 ], and red tilapia [ 174 ].…”

“…The nutritional status of the female shrimp is an important factor that can influence reproductive performance and embryonic development [ 175 , 176 ]. Biofloc can contribute to the nutrition of shrimp and fish by providing a variety of nutrients, including protein, lipids, fatty acids, and vitamin C [ 33 , 165 , 177 ]. Lipids, such as phospholipids and essential fatty acids, are believed to be crucial nutritional factors for the reproductive process, egg-hatching rate, and larval survival of shrimp and fish [ 178 , 179 ].…”

Aquaculture is a crucial industry that can help meet the increasing demand for aquatic protein products and provide employment opportunities in coastal areas and beyond. If incorrectly manage, traditional aquaculture methods can have negative impacts on the environment and natural resources, including water pollution and overuse of wild fish stocks as aquafeed ingredients. Biofloc technology (BFT) may offer a promising solution to some of these challenges by promoting a cleaner and sustainable production system. BFT converts waste into bioflocs, which serve as a natural food source for fish and shrimp within the culture system, reducing the need for external inputs, such as feed and chemicals. Moreover, BFT has the potential to improve yields and economic performance while promoting efficient resource utilization, such as water and energy. Despite its numerous advantages, BFT presents several challenges, such as high energy demand, high initial/running costs, waste (effluent, suspended solids, and sludge) management, opportunistic pathogens (vibrio) spread, and a lack of understanding of operational/aquatic/microbial dynamics. However, with further training, research, and innovation, these challenges can be overcome, and BFT can become a more widely understood and adopted technique, acting as an effective method for sustainable aquaculture. In summary, BFT offers a cleaner production option that promotes circularity practices while enhancing performance and economic benefits. This technique has the potential to address several challenges faced by the aquaculture industry while ensuring its continued growth and protecting the environment. A more broad BFT adoption can contribute to meeting the increasing demand for aquaculture products while reducing the industry’s negative impact on the environment and natural resources. In this context, this review provides an overview of the advantages and challenges of BFT and highlights key technical, biological, and economic aspects to optimize its application, promote further adoption, and overcome the current challenges.

“…Among current production technologies, the bio oc system (BFT) can be considered sustainable in terms of the use of water, physical space, and generation of e uents (Souza et Khanjani et al 2024b). The water in the system can be reused in subsequent production cycles, due to the presence of a microbiota that acts in the cycling of nitrogenous waste, and which, when kept in suspension in the water column by continuous aeration, can be used as a nutritional source for the farmed animals ( When consumed as food, microorganisms in the BFT system can reduce the crude protein content of the feed and/or the feed supply, making the system more economical and contributing to sh performance (Avnimelech 2007 Khanjani et al 2023).…”

This study evaluated potential for rearing the matrinxã, Brycon amazonicus, under different crude protein (CP) levels, using production performance, water quality and animal welfare as indicators. To achieve this, 720 juvenile fish (3.65 ± 0.17 g) were distributed across 24 experimental units (200 L) and fee study lasted 60 days. The study followed a factorial design (2x4), with two production systems: Biofloc technology (BFT) and clear water (CW), and four levels of crude protein (CP = 24%, 30%, 36%, and 42%) in the diet, with three repetitions for each. The study found that the BFT system showed a lower total ammonia level. However, the production system did not have any effect on pH or nitrite concentration. Oxygen levels were found to be lower in the 42% CP group. Fish produced in the BFT exhibited better performance of apparent feed conversion, productivity, and survival. The production system affected total leukocytes and neutrophils in the blood. There was no significant difference in carcass crude protein content and the ether extract content was higher in the animals from the BFT system. Nutritional composition of the biofloc showed differences for ash, with lower levels in the 42% CP treatment. In conclusion, juvenile matrinxã can be fed a diet containing 30% CP in both production systems. Furthermore, the results demonstrated that biofloc did not confer a direct benefit to matrinxã juveniles in terms of their feeding, however BFT represented a promising alternative for increasing the survival and improved animal welfare during the rearing phase.

“…); however, the increasing demand in the market suggests that this species would benefit more from intensification techniques. In this context, biofloc technology (BFT) can be a good approach towards achieving sustainability in pabda fish production; BFT has been evaluated as en effective system for cleaner production of carp and catfishes, enriching food sources, reducing cost for feed, improving water quality and increasing production with better body quality, enzymatic activity, growth and survival (Abakari et al., 2021; Arumugam et al., 2023; Khanjani et al., 2023, 2024; Paul et. al., 2024; Tasleem et al., 2024; Yu et al., 2023).…”

This study analysed morphometric and meristic characteristics of Ompok pabda from two distinct culture systems, namely biofloc and traditional. Fish samples (90 days old) collected from both culture systems were reared in indoor tanks. Thirty‐one morphometric and seven meristic characteristics were measured and analysed. The study showed that the morphometric measurements of various body parts depended on body length. A significant (p < 0.05) positive correlation was observed between total length (TL) and standard length, fork length (FL), highest body depth (HBD), lowest body depth, length of anal base (LAB), post dorsal length (PsDL) and length of caudal fin of fishes from both systems. However, most of the parameters in biofloc technology showed stronger relations than the traditional ones. Further, principal component analysis revealed significant variation across the samples for 60.43% contribution by TL, FL, head length, pre orbital length, LAB, post orbital length, PsDL and HBD in the first PC. Regarding meristic features, namely, anal fin ray, dorsal fin ray, ventral fin ray, pectoral fin ray and branchiostegal ray were found to be significantly varied between the fishes of the two culture systems. Altogether, the variation observed in morphometric and meristic data between the fishes of the two systems has revealed the role of bioflocs. The results of the present investigation might be key features for determining the morphology and growth status as well as for producing consumer‐acceptable/preferred O. pabda in the biofloc system.
