Economic Viability of Biofloc Based System for the Nursery Rearing of Milkfish (Chanos chanos)

Mannanoligosaccharides as a Carbon Source in Biofloc Boost Dietary Plant Protein and Water Quality, Growth, Immunity and Aeromonas hydrophila Resistance in Nile Tilapia (Oreochromis niloticus)

“…Nile tilapia fingerlings in the control groups were reared under a regular daily water exchange system. Meanwhile, the biofloc groups were reared under a static system without water exchange, where the previously prepared biofloc water was mixed with the experimental tank’s freshwater at the ratio of 1:100 (biofloc water: freshwater) [ 22 ]. In order to maintain fully developed biofloc or microbial community conditions, C/N ratio was maintained at 15:1 by the addition of daily carbon sources by dissolving the adjusted amount of each source (glycerol or MOS) in 50 mL water, which was then added to each corresponding tank.…”

Evaluation of different stocking densities and carbon:nitrogen ratios on growth, body composition and production performance of Labeo rohita (Hamilton, 1822) spawn in biofloc based‐nursery system

“…There are presently few species that have been studied in the BFT system at their nursery phase, viz. Oreochromis niloticus (Ekasari et al, 2015), L. vannamei (Khanjani et al, 2016; Lorenzoa et al, 2015; Panigrahi et al, 2017), Rhamdia quelen (Poli et al, 2015), Clarias gariepinus (Fauji et al, 2018), Chanos chanos (Sontakke & Haridas, 2018), GIFT (Sgnaulin et al, 2020) and Mugil cephalus (Haridas et al, 2021). The other species need further research and development programmes.…”

Economic feasibility and risk analysis of Nile tilapia juveniles reared in a biofloc technology system

“…The most signi cant operating cost was that regarding the acquisition of ngerlings, which accounted for 33.24%, followed by feed expenses at 22.42%. Corroborating to these results, Sontakke and Haridas (2018), in their milk sh (Chanos chanos) study, identi ed that the acquisition of sh represented 46.13% of costs, while the feed and carbon source contributed 6.37% and 3.72% respectively, demonstrating that for juvenile production, the acquisition of ngerlings has a signi cant economic impact. These same items also showed greater importance in terms of costs in the study conducted by Taniguchi (2010), in which they evaluated the economic viability of tilapia juvenile production in earthen ponds, and where ngerlings and feed contributed 42% and 38.2% respectively.…”

“…2013). BFT represents an alternative that overcomes some of the main problems of modern aquaculture, such as water consumption, land use, and feed costs(Sontakke and Haridas, 2018). Tilapia juveniles cultured in ponds can generate a consumption of 35,000 liters of water per kilogram produced(Jatobá et al 2019;Yacout et al 2016).…”
