“…Dorame et al (2014) identified that P. vannamei reared in biofloc-based systems showed an improved physiological performance as indicated by selected haemolymph parameters including SOD activity. Similarly, Haraz et al (2018) reported an increased expression of SOD in BFT treatments compared to control which may be due to a development of an antioxidant defense system in Nile tilapia when reared under biofloc based system. Similarly, biofloc supplementation showed a significant higher SOD activity in biofloc raised Nile tilapia (Bairagi et al, 2002;Long et al, 2015) and crucian carp (Wang et al, 2015).…”

The study was conducted to evaluate the effect of different carbon sources in biofloc based system for rearing amur carp (Cyprinus rubrofuscus Lacepede 1803) fingerlings in inland saline groundwater. The study was undertaken in a complete randomised design (CRD) where each treatment was performed in triplicate. The experimental unit consisted of four different carbon sources viz., T1 (tapioca flour), T2 (wheat flour), T3 (rice bran), T4 (jaggery) and control (C) with water exchange for a duration of 45 days. Each tank (500 l) was stocked with 30 fingerlings with an average body weight of 11.17±0.34 g. At the end of the rearing period, biofloc based treatments showed significantly better growth performance compared to control. Among the treatments, jaggery based biofloc system showed the highest biomass (629.4±1.58 g), specific growth rate, SGR (1.32±0.03 % day-1), protein efficiency ratio, PER (0.29±0.05), and lowest feed conversion ratio, FCR (0.56±0.03). Digestive enzymes of the biofloc reared fishes showed enhanced activity compared to control group. Jaggery based biofloc (T4) showed significantly higher non-specific immune response in terms of respiratory burst activity (1.14±0.01), superoxide dismutase (44.59±0.19 U mg protein-1) and catalase (1.59 ± 0.01 U mg protein-1) activity compared to other biofloc treatments and the control. The present study concluded that jaggery is best as compared to others carbon sources tested (tapioca flour, wheat flour and rice bran) for better growth, non-specific immunity and digestive enzyme activity of amur carp fingerlings in biofloc based rearing system using inland saline groundwater.

“…It consisted of four treatments in three replicates and were designated as the following; T0 (control group: a basal feed without ALE), T1 (1% of ALE in fish feed), T2 (a diet supplemented with 2% ALE), and T3 (a diet supplemented with 3% ALE) fry were cultured (7.0 m, 1.6 m, 1.0 m) each; length, width, depth) and volume 11.2 m3 with an average initial weight of 4.04 ± 0.03 g and were randomly distributed at a stocking rate of 450 individuals/ tanks for total 105 days. Each fish tank was dried, cleared, and add cattle dung 50% of the total organic fertilizers, Urea 1.25 kg, poultry manure 45.0 kg, and di-ammonium phosphate (DAP) 2.5 kg and left the tanks for 15 days before experimental study and culture of Nile tilapia by following the methods of Haraz et al (2018) .…”

A 105-day experimental trial was conducted to assess different levels of dietary Aleo vera extract supplementation on water quality parameters, proximate composition, growth performance and haematological parameters of fry Oreochromis niloticus. Four different percentages of dietary leaf extract powder of Aleo vera (ALE) with a basal feed, designated as, i.e., T0 (Control group; without ALE), T1 (1% ALE), T2 (2% ALE), and T3 (3% ALE). Fish fry was reared in concrete tanks (7.0 m, 1.6 m, 1.0: L, W, H; water volume 11.2 m3/tank), with an average initial weight 4.04 ± 0.03 g/ fry, and each treatment was triplicated. Fry was randomly distributed at a stocking rate of 450 individuals/ tanks. The water quality parameters revealed that temperature, pH, salinity, dissolved oxygen (DO) and nitrates were found in a promising range as given by FAO/WHO limits. However, the record values obtained for Electric Conductivity (EC), Total dissolved solids (TDS), and alkalinities were not found in all tanks' suitable range according to FAO/WHO limits. The results revealed a significant impact of different percentages of dietary ALE supplementation on fry's body composition and haematological parameters. Moreover, the final body weight, final body length, average daily weight gain (g), net weight gain (g) and specific growth rate (%) were significantly higher (p < 0.05) in T1 and T2 compared with T0 and T3 treatments. The poorest feed conversion ratio was recorded in the T2 group compared with other treatments. Thus, the current study provides information about the nutritional quality of Nile tilapia culturing in Pakistan.

“…Luo et al [20] obtained productivity levels: 1.78%/day (specific growth rate), 71.43% (feed efficiency), 32.72 kg/m 3 (productivity), and 97.00% (survival) by using tilapia seeds with an initial size of 15.62 g and a density of 128 fish/m 3 . Haraz et al [29] obtained a specific growth rate of 2.11%/day, feed efficiency of 102.04%, the productivity of 9.5 kg/ m 3 , and a survival rate of 90.50% by using seeds with an initial size of 5.23 g and a stocking density of 300 fish/m 3 which were maintained for 98 days. While Jorge et al [24] revealed productivity up to 32.24 kg/m 3 using a C: N ratio of 10-20:1 and a seed size of 38.4 g. [30] showed the productivity range of 3.35 -4.90 kg/m3 by using seeds with an initial size of 98.45 -100.68 g which were reared for 12 weeks.…”

One of the technologies that can produce a high number of fish in limited land and water is biofloc. Adapting biofloc technology in Indonesia from laboratory to industrial scale requires several improvements. This study aims to optimize biofloc technology and to reduce production costs. A series of research activities to increase the productivity of tilapia by biofloc technology have been carried out using superior seeds variety, proper application of stocking densities, type and volume of tank/pond, and the seed size at the stocking. Feed efficiency, productivity, survival rate, specific growth rate, and economic parameters were observed. Using tilapia superior seed can increase biomass by 4% compared to Nirwana II tilapia variety. The best seed density that can be used is 75-80 fish/m3, it is related to the appropriate type or volume of the round tank, which is 10 m3. The correlation value (R2) between the size of the initial seed and the observed parameters were 0.9439 (specific weight gain rate); 0.5841 (feed efficiency); 0.4880 (productivity) and 0.4789 (survival rate). Optimization of biofloc technology can save production costs up to 38.41 %. The value of the R/C ratio is 2.03.
