“…Yu, et al [67] reported that decreased expression of IL-1β and TNF-α indicated that BFT could enhance immunity of golden crucian carp. Additionally, the results of immune-related genes agree with Menaga et al [68], who illuminated that tilapia reared under BFT conditions showed upregulated pro-inflammatory cytokines like (TNF-α and IL-1β). Menaga et al [68] stated that the upregulation of immune and pro-inflammatory related genes modulates the immune response of fish reared in BFT conditions.…”

Menaga et al [68] stated that the upregulation of immune and pro-inflammatory related genes modulates the immune response of fish reared in BFT conditions. Some studies have shown that the boost of IL-1β and TNF-α is closely related to the secondary metabolism of microorganisms and the BFT contains many microorganisms [69].…”

The present study investigated the effect of stocking density and dietary carbon sources on the water quality, oxidative status, and immune-related genes of Nile tilapia (Oreochromis niloticus) reared under biofloc conditions (BFT). Eight groups were established at two levels of stocking densities (140 fish per m3: low stocking density, LSD) and (280 fish per m3: high stocking density, HSD) (5.15 ± 1.12 g) and kept in eight biofloc units containing water without carbon sources (control groups) or with glycerol, molasses, or starch. Red blood cells count, hemoglobin, and hematocrit values were reduced in fish stocked in control groups at LSD and HSD than biofloc groups. Control fish groups reared at both LSD and HSD have the highest significant (p < 0.05) white blood cells number than other fish groups. Meanwhile, fish groups that received glycerol, molasses, and starch maintained in both LSD and HSD presented a higher significant (p < 0.05) monocyte % than in the control group reared at both LSD and HSD. The fish group reared in biofloc conditions (BFT) using starch carbon source and reared at the HSD presented a significantly higher (p < 0.05) increase in total serum protein and albumin levels as well as globulin value than the control fish group reared at both LSD and HSD. The highest glucose and cortisol levels were showed in the control fish group reared at both LSD and HSD. Fish maintained in glycerol-based biofloc at LSD attained the highest (p < 0.05) serum superoxide dismutase (SOD), glutathione reductase (GR), and catalase than other experimental groups. Regarding the nonspecific immune status, significantly increased expression of CC-chemokines, CXC-chemokines, TLR7 and IL-8 genes was found in molasses based biofloc groups. The data of the present study revealed that using molasses promotes health status of Nile tilapia cultured in a biofloc system.

“…In BFT system, carbon sources are added to stimulate bacterial growth and heterotrophic ammonia nitrogen uptake through the production of microbial proteins (Avnimelech, 1999; Chakrapani et al, 2020; Ridha et al, 2020). The uptake of nitrogen by the heterotrophic bacteria is faster than regular nitrification process (Menaga et al, 2019). A stable and diverse bacterial communities in BFT are primarily responsible for maintaining water quality in the system (Khanjani & Sharifinia, 2020).…”

Aquaculture systems are becoming more intensive to increase economic efficiency (Ren et al., 2019). Large amounts of feed are put into the systems to enhance the growth of cultured animals, which leads to an elevated concentrations of organic waste from uneaten feed and faeces. Ammonia is produced when those organic waste is decomposed (Li & Boyd, 2016). The conversion methods for removing ammonia nitrogen in aquaculture systems are photoautotrophic removal by algae, autotrophic bacterial conversion of ammonia to nitrate and heterotrophic bacterial conversion of ammonia-nitrogen directly to microbial biomass (Dauda, 2020;El-Sayed, 2020). None of the three pathways exist alone, and the dominant one depends on the management of the aquaculture systems (Dauda, 2020).

“…Traditional extensive culture methods were replaced with semi-intensive and intensive production systems. Tilapia are also attractive as a co-cultured fish because of their potential to improve water quality, especially in penaeid shrimp ponds, by consuming plankton and detritus and by altering pathogenic bacterial populations while increasing marketable production (Menaga et al, 2019). Culture of GIFT has been successfully done in biofloc system as BFT helped improve optimum growth and better immune status of of the fish.…”

“…Culture of GIFT has been successfully done in biofloc system as BFT helped improve optimum growth and better immune status of of the fish. The possibility of utilization of biofloc-based zero water exchange system to ensure bio-security and environmental sustainability in farming and inland saline water farming has been attempted and ensured (Menaga et al, 2019). GIFT strain of Tilapia at higher stocking densities 200-250 m −3 has been considered as optimum stocking density whereas higher stocking densities up to 350 nos m −3 may also be reared in the biofloc systems without compromising the growth and immunity (Menaga et al, 2019).…”

Tilapia production in India is booming in recent years. Pond, tank and cage culture of the introduced improved strains of tilapia is being supported to compete the domestic as well as international market. The culture production is being intensified using modern tools such as cages and biofloc technology. At the same time several issues covering unregulated culture and breeding practices, unethical culture technology, and callous approach towards disease management are emerging now a days requiring immediate attention to make tialpia intensive production sustainable. Looking at the promises and prospects of intensive tilapia culture, proposals for future improvement in tilapia farming are suggested. There is need of responsible production and organised distribution of improved stocks, better formulated floating feeds, deployment of advanced aquaculture production systems, monosex culture and continued quarantine and tighter biosecurity standards.
