“…In all the tanks, Biofloc formation was observed just in 3-4 days, which is characterized by low water transparency and high Biofloc volume index. In the present study, as the algae and bacteria have oxygen demand, DO levels were properly maintained around 6.5 mg/lit in all the Experimental tanks and ideal for the cultivation of Penaeid shrimp [29][30][31] . The continual aeration and high phytoplankton biomass in the experimental feeding trail tanks may have increased photosynthetic activity, as evidenced by the high concentrations of chlorophyll-a.…”

Using a variety of external carbon sources, including molasses, tapioca, maize flour and sucrose in combination for the development of bio flocs, an attempt has been made to investigate the effects of adding both probiotics (Bacillus licheniformis and Lactobacillus rhamnosus) and the Biofloc system on water quality parameters and the performance of Pacific shrimp, Litopenaeus vannamei, under a 15: 1 carbon to nitrogen ratio in the current experimental feeding trail. Feeding trail experiments were conducted with Seven Experimental diets including One Control, Probiotics added and Five Bioflocs developed with different external Carbon sources for a period of 60 days with L. vannamei. Due to the addition of combinations of both Probiotics and Bioflocs, maintain rigorous control of all the Water quality parameters and provide protection and resistance to the Candidate species of culture i.e. all the Water quality parameters were ideally maintained. Intense mechanical aeration also favours degradation of toxic nitrogen and other compounds by the microbial community that additionally serve as a food supplement for shrimp, thereby Productivity rates were substantially increased. Therefore, BFT is an efficient alternative against pathogens, maintenance of water quality at optimum levels and enhances survival and growth of shrimp L. vannamei. The combined use of both Probiotics and Bioflocs in the present study not only maintains a good Water quality parameters and also Growth performance in L. vannamei.

Biofloc technology (BFT) has gained popularity recently as the aquaculture industry faces significant economic losses due to water pollution creating various pathogens. Many bacterial, viral and fungal diseases in fish cause a decrease in annual world fish production. Therefore, owing to a growing demand for healthy fish, zero‐water exchange is widely practiced in fish and shellfish production. It minimizes the release of aquaculture wastewater into the aquatic ecosystem, which contains nutrients, organic matter and pathogens. It uses a minimal amount of land, which provides an impartial cost–benefit ratio to maintain socio‐economic sustainability. Besides sustainability, fish cultured in the BFT have also expressed better health status after being challenged by different pathogens. However, this review explores the use of BFT as a sustainable approach to wastewater utilization and fish and shellfish production. Apart from this, the review highlights the potential of BFT to enhance fish production in aquaculture systems and discusses various factors that affect the performance of systems, such as carbon‐to‐nitrogen ratios, aeration and the use of probiotics. It also investigates the role of biofloc in improving water quality, fish and shellfish health prophylactic properties, and its effect on gut microflora. The review further examines the economic feasibility of BFT and discusses about the cost‐effectiveness of implementing systems and the potential for generating additional revenue through the sale of bioflocs as a value‐added product. Overall, this review highlights the potential of BFT as a sustainable solution for wastewater utilization and increasing fish production. It provides valuable insights into the factors affecting the performance of BFT systems and suggests areas for further research and development in this field.
