“…153 Catla was especially efficient in harvesting bioflocs compared with rohu and mrigala, reflected in the higher growth rate of catla compared with the other species. 153 Similarly, an earlier study showed that a feed mix prepared by combining commercial feed (50%) and wet bioflocs (50%) composed of bacteria, protozoa, algae, rotifers and fed to Labeo rohita resulted in the enhancement of growth parameters such as SGR, PER, FCR and net yield. 203 These results imply that the nutritional constituents of the microbial protein are able to meet the nutritional requirements of rohu.…”

“…These findings reveal the ability of this new cross between Cyprinus carpio and red crucian carp to harvest and utilise bioflocs as food sources. Bioflocs composed of 35.14% CP, 47.42% carbohydrate, 2.16% crude lipid, 17.2% fibre and 15.28% ash were recently found to be highly consumed and utilised by Indian major carp (rohu, Labeo rohita ; catla, Catla catla , mrigala and Cirrihinus mrigala ) and to be favourable food sources enhancing their growth performance 153 . Catla was especially efficient in harvesting bioflocs compared with rohu and mrigala, reflected in the higher growth rate of catla compared with the other species 153 .…”

The abundance of nitrogen compounds, phosphorous compounds and organic matter in biofloc technology (BFT) aquaculture systems creates an ideal medium for increasing microbial communities and load. The abundance of microbial DNA found in BFT aquaculture systems is hypothesised to be among the greatest in current aquaculture systems. Several factors mediate the bacterial diversity, relative abundance and dynamics in BFT systems. This review focusses on the bacteria in BFT aquaculture systems, their role as food for animals present in the culture and their various relationships with major nutrients. The analytical techniques available for determining bacterial integrity and function are reviewed along with the factors that affect microbial community structure, water quality and production performance. Future investigations to characterise bacteria in BFT aquaculture systems and their roles and mediating factors are suggested.

“…Therefore, the discharges from aquaculture systems should be kept to minimum levels to mitigate the subsequent environmental impacts (Gilles et al, 2014). Several biological strategies and techniques have been used to improve the quality of aquacultural effluents including combined extensive and intensive fish ponds (Jaeger et al, 2021), artificial freshwater wetlands, aquaponics (Huang et al, 2019; Nuwansi et al, 2019; Zhimiao et al, 2019), using macroalgae and microalgae as biofilters (Ansari et al, 2017; Mohamed Ramli et al, 2018), and bio‐flocculation technology (Deb et al, 2017, 2020).…”

Integrated aquatic systems are used to decrease the nutrient loads of effluents negating the negative environmental impacts of aquacultural systems. Some of these systems have a separate algae compartment requiring high maintenance. An integrated culture system was set up with different trophic levels: algae, zooplankton, and fish. The algal tank was in‐line with the fish and zooplankton components to minimize the maintenance required for the algae. A control flow‐through system was also set up without the algae and zooplankton compartments. The systems were run for 6 weeks, and water temperature, pH, dissolved oxygen, NO3, NO2, NH4, and PO4 concentrations were measured. A removal rate was determined for each water parameter and the densities of the algae and zooplankton species were measured in each compartment of the integrated system. The concentrations of most nutrients in the integrated system were similar to those of the control system. The density of algae increased during the first 3 weeks and remained almost stable until the end of the experiment. There was an inverse relationship between the densities of two zooplankton suggesting compensatory effects on the control of the algal bloom. The integrated system improved water quality with minimal algal culture maintenance, water exchange, and no fish mortality. Practitioner Points An integrated system could effectively reduce the nutrient load of water. Water replacement in the integrated system was significantly lower than that of a flow through system. The inline plankton culture tanks decreased greatly the maintenance of the system.
