“…The survival rate proposed in the optimistic scenario is in agreement with the data obtained by Hisano et al (2021), who produced tilapia juveniles in a BFT and obtained a 100% survival rate in 60 days. Conversely, data interpretation would not be possible without the stochastic simulation; this tool assists sh farmers to make decisions within lower levels of risk (Castro et al 2007).…”

This study aimed to analyze the economic feasibility and the risk associated with the Nile tilapia juveniles cultured in a biofloc technology system. The indicators used in this study followed the operating cost criterion. Scenarios were analyzed in terms of variations in input prices and survival. Stochastic simulation were also carried out in order to determine the probabilities of economic results. The items with the greatest impact on costs were the acquisition of the greenhouse and fingerlings, which represented 27.64% (initial investment) and 33.24% (operating cost) respectively. The analysis showed that the biofloc technology system is viable in a short and long term, since it covered all the operational costs and showed a positive gross margin per production cycle, except in the pessimistic scenario. The risk analysis demonstrated that in 87.29% of the simulations obtained a positive profit. Thus, the tilapia juveniles production in biofloc technology system is a low-risk and economically viable investment.

“…The growth rates and feed efficiency of Nile tilapia in the present study were much higher in BFT‐based groups than in the control group; but no differences were found between the molasses‐ and macrophyte‐based groups. The improvement in fish performance in macrophyte‐based treatments may have been attributed to the direct consumption of biofloc communities as a natural food source, as reported by other researchers (Avnimelech, 2007; Azim & Little, 2008; Haridas et al, 2017; Hisano, Barbosa, et al, 2021; Luo et al, 2013, 2014).…”

“…However, it appears, at least under the conditions of this experiment, that Nile tilapia can tolerate much higher TSS values. Azim and Little (2008), Silva et al (2017) and Hisano, Barbosa, et al (2021) reported high TSS values of 1000 mg L −1 , 1150–1702 mg L −1 and 1389.8 mg L −1 , respectively, without affecting fish growth. The non‐occurrence of any apparent negative effects on growth, survival and overall health status of Nile tilapia in the present study may support this assumption.…”

“…Different carbon sources have been widely used in tilapia culture in BFT systems with promising results. These sources include corn flour (García‐Ríos et al, 2019), wheat flour (García‐Ríos et al, 2019), oligosaccharides (Kishawy et al, 2020), sugar (García‐Ríos et al, 2019; Hisano, Barbosa, et al, 2021; Liu, Luo, et al, 2018; Long et al, 2015) and molasses (Hisano, Barbosa, et al, 2021; Khanjani, Alizadeh, & Sharifinia, 2021; Laice et al, 2021). The effectiveness of carbon supplementation depends on the carbon source, quality and quantity, time and frequency of application, total ammonia–nitrogen (TAN) concentration in the water, exogenous supplemental feeds and fish size and stocking density (El‐Sayed et al, 2021; Khanjani, Alizadeh, & Sharifinia, 2021; Shourbela et al, 2021).…”

Two freshwater macrophytes, water (Eichhornia crassipes) and coontail (Ceratophyllum demersum), were evaluated as carbon sources in biofloc system for Nile tilapia (Oreochromis niloticus), in comparison with molasses and a RAS with 10% water exchange daily (control). All-male tilapia (9.35 g) were stocked in 70-L fibreglass tanks at 10 fish tank −1 and fed on a commercial diet (30% cp) for 60 days. The average water temperature, pH and dissolved oxygen (DO) did not significantly differ (p > 0.05) among all treatments. Total ammonia-nitrogen (TAN) was significantly lower in the control group (0.11 mg L −1 ) than in biofloc treatments (0.15-0.17 mg L −1 ). Nitrite (NO 2 -N) concentrations were significantly lower, while nitrates (NO 3 -N) higher, in bioflocbased treatments (20.23-25.77 mg L −1 ) than in the control group (12.85 mg L −1 ). Biofloc volume (BFV) (28.17-33.50 ml L −1 ) and total suspended solids (TSS) (691-824 mg L −1 )were not significantly different among molasses and macrophytes treatments. The control group displayed lower growth rates and feed efficiency than macrophytesbased groups. Blood parameters, immunological responses, digestive enzymes activities, liver function enzymes and upregulation of IFNγ, TNFα and IL-8 genes were significantly better in molasses-and macrophytes-treated tanks than the control group. These results suggest that water hyacinth and coontail can be used as costless, eco-friendly carbon sources in biofloc systems.

“…Understanding the fish's haematological and biochemical characteristics is essential, which is a tool for monitoring environmental, physiological and pathological changes (Fazio, 2019). Limited studies are reported on fish feed and habitat that influence the growth, haematological and biochemical characteristics (Fazio et al, 2018; Hisano et al, 2021). The environmental changes affect the physico‐chemical parameters of water, which also influence fish haematology, growth and health (Habib, Fazio, et al, 2021).…”

Assessing fish haemato‐biochemical profile and growth performance is essential to monitor the influence of fish feed and habitat on fish physiology. The influence of two regularly used different commercial feeds and varied environments such as pond and biofloc systems on haemato‐biochemical and growth parameters of Oreochromis niloticus was studied by the results of 4‐month experiment. Fish ponds and biofloc systems where all the fish were supplied either feed A and B were surveyed weekly. The crude protein content of feed A was 30%, while that of feed B was 28%. Physico‐chemical characteristics of water in all culturing systems were suitable for Nile Tilapia production throughout the study period. Results revealed a significant difference (p < 0.05) in most haemato‐biochemical parameters. Growth performance was better in fish fed on feed A than feed B in both culture systems. In between, the habitat wide range of haemato‐biochemical indices and fish growth parameters were significantly higher in biofloc technology than pond culture system. However, no significant difference (p > 0.05) was recorded in fish enzymatic activities in both systems. Furthermore, it was found that both the length and weight gain were positively associated with the crude protein of the feeds. However, in the case of biofloc, crude protein of both feeds works far better than the pond, as indicated by the p‐value and regression R square. Current study delivers the basic knowledge to observe fish blood and growth parameters, which could be essential to understanding the fish culture management and environment.
