“…Overall, the BFT had much higher TSS and BOD5 than the control with maximum at the last sampling point. These results agree with other work reported by Li et al (2018a) for biofloc tanks stocked with Gibel carp (Carassius auratus) that reported similar amount of TSS and BOD5 as our work, without any water exchange. The slow decline in levels of DO was probably caused by higher biological demand associated with total water biomass increment and the cumulating of biological materials and temperature range.…”

In spite of various advantages of biofloc technology in aquaculture, few studies have focused on the health status of fish in biofloc system. In this survey, the effect of cane molasses as a carbon source of biofloc system on hemato-immunological parameters, antioxidant status, and stress indicators of common carp (Cyprinus carpio) was investigated. Four hundred and twenty juvenile common carp (40.2 ± 5.76 g) were randomly divided into four equal groups in triplicates as follows: groups A, B, and C were reared in biofloc system with molasses as a carbon source with C/N ratio of 15, 20, and 25, respectively, whereas control group (D) was reared in similar intensity without biofloc system. Fish were reared for 90 days and samples were taken on days 0, 30, 60, and 90 of the experiment. Immunological parameters including serum lysozyme and bactericidal activity, serum complement and IgM level, and NBT reduction and resistance to bacterial challenge as well as hematological parameters (RBC, WBC, hematocrit, hemoglobin) were assessed in experimental groups. Meanwhile, antioxidative enzyme activity (glutathione and superoxide dismutase, catalase) and stress indicators (glucose and cortisol level) were measured and compared among the groups. Water quality parameters were evaluated in all groups. Results showed that most of the immunological parameters as well as resistance against bacterial infection increased in biofloc groups (particularly in C/N = 20 groups) (P < 0.05). Hematological parameters and antioxidative enzyme activity were not affected by biofloc systems. Stress indicators showed a significant decrease in biofloc system, particularly in C/N = 20 group compared with control (P < 0.05). The results indicated that biofloc system (particularly C/N ratio = 20 groups) could not only improve immunological parameters, antioxidative status, and water quality but it decreased stress statues of common carp.

“…Therefore, BFT is generally believed to be efficient only for the cultivation of filter‐feeding fish and shrimp species (Hargreaves, 2006) such as Macrobrachium rosenbergii (De Man) (Asaduzzaman et al, 2008), Litopenaeus vannamei (Boone) (Asaduzzaman et al, 2008; Martins et al, 2016; Xu et al, 2012) and tilapia (Avnimelech & Kochba, 2009; Crab et al, 2009; Zhang et al, 2016). Nevertheless, recent studies have shown that BFT systems can be used to culture many non‐filtering fish, such as Ictalurus punctatus (Rafinesque) (Green, 2015), Clarias gariepinus (Burchell) (Abu Bakar et al, 2015), Carassius auratus (Linnaeus) (Li et al, 2018) and Cyprinus carpio (Linnaeus) (Bakhshi et al, 2018).…”

Effects of different biofloc sizes on the short‐term stress of Japanese seabass, Lateolabrax japonicus (Cuvier), juveniles reared in biofloc aquaculture systems

Biofloc technology (BFT) is a new approach widely studied and applied in aquaculture (Avnimelech, 2012). In BFT systems, the bacterial communities involved in water treatment processes are stimulated to grow in suspension and form flocs through flocculation mechanisms. The major role of flocs in aquaculture is their ability to treat aquaculture water for continual use over several production cycles (Avnimelech, 2012;Kim et al., 2020), as natural food and probiotics (Avnimelech, 2012). BFT systems can also be associated with the set-up of recirculating aquaculture systems (RAS) and are often applied in the treatment of wastewater (Liu et al., 2021).However, when the C/N ratios in BFT are elevated in the aquaculture system, they not only maintain and enhance growth, including the population of microorganisms involved in heterotrophic assimilation and conversion of ammonia nitrogen into bacterial biomass, but also create problems, such as the rapid growth of flocs and total suspended solids (TSS) (Avnimelech, 2012;Hargreaves, 2006). In the BFT, high TSS levels can simultaneously increase the difficulty of controlling parameters such as dissolved oxygen (DO) (Avnimelech, 2012;Hargreaves, 2006) and exert biological effects of chronic stress on aquatic animals, thus affecting the stable operation and

“…Bioflocs gained wide recognition because of their availability as a supplemental food source for cultured shrimp and the enhancement of conversion from inorganic nitrogen to microbial biomass with helping of heterotrophic bacteria in bioflocs (Avnimelech, 1999). Although the bioflocs' effectiveness to control inorganic nitrogen, promote growth, and enhance immunological responses has been well documented in shrimp and fish farming (Ebrahimi, Akrami, Najdegerami, Ghiasvand, & Koohsari, 2020; Kamilya et al, 2017; Li et al, 2018), the reports of bacteria screening from biofloc for nitrogen removal are still limited in aquaculture.…”

The development of intensive aquaculture industry has aggravated the dangers of ammonia and nitrite in aquatic ecosystems. Probiotics have been widely used to maintain and improve water quality by removal of ammonia and nitrite in aquaculture. In this study, two facultative anaerobic strains AB15 and NB14, capable of efficient ammonia and nitrite removal, were isolated from biofloc, which acts as a natural micro‐flora storeroom in shrimp culture ponds, and were identified as Vibrio sp. and Pseudomonas fluorescens, respectively. The removal efficiency of ammonia and nitrite by AB15 and NB14 was 96.8 and 89.6%, respectively. The optimum conditions of AB15 and NB14 were as follows: temperature (25°C vs. 30°C), salinity (25‰ both), initial pH (7.5 vs. 8.0), C/N ratio (15 vs. 10). The two strains had great performance on inhibiting the common pathogens (Vibrio harveyi, Vibrio splendidus, Vibrio anguillarum) in aquaculture at concentrations of 105–108 CFU/mL. Biosecurity assessment indicated that both AB15 and NB14 were harmless for survival and could be beneficial for the growth and immune enhancement of Litopenaeus vannamei. All results demonstrate that the two isolated strains have high promise for future applications of removing ammonia and nitrite and maintaining biosecurity in shrimp culture ponds.
