“…The control and malt groups had close growth parameters. The reason behind the higher final mean weight of tilapia in the wheat and malt BFT compared to the sugar BFT could be attributed to the enhanced metabolism as a result of ingesting the bacterial enzymes utilized in the degradation of these complex carbon sources (Hargreaves, 2013; de Lima et al., 2018). However, it is unlikely that the higher nitrogenous compounds in the malt flour BFT had adverse effect on growth since tilapia in the control and malt flour BFT treatment had close values for FMWT.…”

This study compared the effect of three sources of carbohydrates: sugar, wheat and malt flours, on water quality, water consumption, bacterial load, growth and flesh quality of Nile tilapia. Adults (120.6 ± 0.64 g) were stocked in 1.2‐m3 fibreglass tanks at a rate of 25 fish/m3. Carbohydrates were added to the biofloc tanks at a C:N ratio of 20:1. Water flow in the non‐biofloc control tanks was adjusted to 0.6 L/day. The 105‐day experiment was conducted in triplicates. Results showed that biofloc treatments (BFT) with zero water exchange had significantly higher mean total ammonia, nitrites, nitrates, alkalinity, total suspended solids and lower pH than the control treatment. The sugar BFT had the highest floc volume. Growth parameters and feed conversion ratio did not differ significantly among treatments. However, tilapia in the malt flour and control treatments had close values. Gross fish yield was higher (p < .05) in the control than the BFT treatments. Water consumption/kg tilapia produced in the control was 42 times higher than the BFT groups. Protozoa dominated the biofloc biota, and wheat flour was the best in harbouring higher bacterial populations in the gut. Protein content and ∑n‐3 fatty acids were highest in the wheat flour biofloc, while malt flour biofloc had the highest lipids. The sugar biofloc had the highest n‐3/n‐6 ratio. Tilapia muscles in the malt flour and control treatments had the highest protein and lipid contents respectively. Tilapia muscles in the wheat flour BFT had the highest ∑n‐3 fatty acids and n‐3/n‐6 ratio. It can be concluded that farming tilapia in BFT using malt or wheat flours as carbon sources is more economical in saving great amount of water with minimal discharge of pollutants without affecting tilapia growth or flesh quality.

“…A positive effect was noted for the addition of a carbohydrate source to a system dominated by predominantly heterotrophic microbiota, favoring the assimilation of the ammoniacal nitrogen from the excretions and feed leftovers; thus, low concentrations were ensured. This decrease in total ammonia by the addition of carbohydrate was also observed in the studies of Avnimelech (1999), Hargreaves (2006), Ray and Lotz (2014), Lima et al (2018), Ren et al (2018), and Poli et al (2018). The effectiveness of BFT was confirmed by observing the average ammoniacal nitrogen concentrations, which presented values within the range tolerated by tilapia, i.e., 1.0 ± 0.5 mg L -1 at a C:N ratio of 20:1.…”

“…In order to choose the carbon source, one must take into account its availability and ease of acquisition, as well as its carbohydrate content (Emerenciano et al, 2017). Among the sources tested are glucose (Ekasari et al, 2010), starch (Crab et al, 2007), wheat bran, sugar (Poli et al, 2018), molasses (Lima et al, 2018), and sugarcane bagasse (Hargreaves, 1998). Among the sugars obtained directly from concentrated sugarcane juice (Saccharum officinarum), brown sugar is a carbohydrate that does not receive chemical treatment during production, is rich in vitamins and minerals, and is commercially available at sucrose contents that vary between 90% and 99.8% (Machado et al, 2012).…”

Zootechnical Performance Evaluation of the Use of Biofloc Technology in Nile Tilapia Fingerling Production at Different Densities

The effect of producing and culturing Nile tilapia (Oreochromis niloticus) fingerlings in biofloc technology (BFT)-based systems was investigated in terms of zootechnical performance, aiming to define the best culturing density for 64 days. A completely randomized design was used, with four replications totaling 24 experimental units. The weight gain of each batch of animals per experimental unit (E.U.) was evaluated at densities of 200, 400, 600, 800, and 1,000 fingerlings m-3. For controls, a Water Recirculation System with 248 fingerlings m-3 was used. The fingerlings were fed commercial feed containing 35% protein and brown sugar as a carbohydrate source at a C:N ratio of 20:1. Dissolved oxygen, total ammonia nitrogen, pH, and temperature were monitored daily, and nitrite and alkalinity were monitored weekly. The analysis of weight gain data obtained a linear function y =-0.0017X 2 + 3.724X-87.77, with r 2 = 0.864, coefficient of variation = 14.23%, and correlation coefficient = 0.91. At the end of the cultivation period the system's planktonic community presented high diversity, dominated by rotifers and diatoms. The data of survival, density management demand, and physicochemical parameters variations of the water suggested an optimal density of 800 fish m-3 , since this resulted in an average weight gain per E.U. of 1,891.25 ± 151.24 g, with a productive efficiency index of 274.96 that is approximately three times that of the control treatment (87.43). Biofloc technology can be employed in two-phase super-intensive Nile tilapia culture systems, with a stocking density in the rearing stage of 800 fish m-3 .
