“…This result might be explained by the fact that BFT uses less water than traditional systems, leading to retaining more suspended solids and particulates in the water column. The concentration of TSS in the designed BFT system strengthened the findings of other researches who reported high TSS in biofloc systems with different carbon sources (Legarda et al., 2019).…”

“…Moreover, Proteobacteria and Bacteroidetes were the common phyla in RAS biofilter in both freshwater and marine water RAS, and the most numerous nitrifying and denitrifying bacteria in the RAS (Legarda et al., 2019; Ruan, Guo, Ye, Liu, & Zhu, 2015; Rud et al., 2017). Sphingobacterium, Novosphingobium and Nitrospira also accounted for higher abundance in RAS.…”

In a 2‐month trial, four different aquaculture systems, viz., (a) rearing at 50% daily water exchange without filtration (WE), (b) biofloc system (BFT1), without water exchange or filtration, (c) biofloc system (BFT2), similar to BFT1 but 10% of daily feed deducted, and (d) recirculating system (RAS), without water exchange, were compared through monitoring water quality as well as measuring the growth, haematological and immunological indices of common carp (Cyprinus carpio). Metagenomics was also applied to characterize the microbial profile of the waters through screening 16S rDNA gene sequences. BFT systems demonstrated lower values of pH, dissolved oxygen but did higher concentration of total suspended solid (TSS) and 5‐day biochemical oxygen demand (BOD5). No significant change was observed in haematocrit, haemoglobin, albumin, total protein and total cholesterol of the fish kept in all treatments. Metagenomics analysis revealed the highest abundance for Proteobacteria in BFT1, BFT2 and RAS systems, whereas Firmicutes was the dominant phylum in WE treatment. At the genus level, Flavobacterium (in BFT treatments), Sphingobacterium (RAS) and Rhodoluna (WE treatment) were the dominant bacteria. Taken together, BFT treatments could improve water quality and feed utilization. Moreover, BFT and RAS rearing conditions might change microbial structure of water.

“…The integration of white shrimp and another mullet species ( Mugil curema ) in a BFT system was also evaluated (Legarda et al . 2019). The shrimp were fed on 35% cp commercial feed using preset feeding table, while mullet were offered a 40% cp feed, once a day, at 1% of their biomass, to stimulate biofloc consumption.…”

In face of the shortage of, and competition with, land and water, the sustainability of aquaculture will have to depend on vertical development, through improving production environments, increasing productivity and enhancing aquaculture technologies. Biofloc technology (BFT) has emerged as new alternative for sustainable aquaculture, which could contribute to FAO Sustainable Development Goals (SDGs) related to food security. Extensive research has been carried out on the development and application of BFT in aquaculture since early 1990s, with emphasis on shrimp culture. Over 40% of BFT publications in aquaculture were directed to shrimp farming. Therefore, I strongly believe that the accumulated knowledge on the applications of BFT in shrimp farming and the experience gained, especially during the last 10 years (2010–2020), are now more than worthy of critical review and analysis. This review summarizes the most update knowledge on the use of BFT in different marine shrimp and freshwater prawn aquaculture. Emphasis has been on factors affecting shrimp production in BFT systems, integration of biofloc‐based shrimp farming with other aquatic farmed species, nutritional value of bioflocs as a natural food or feed ingredient for farmed shrimp and prawn, the application of BFT in different rearing phases, the use of biofloc as a natural probiotics and their effects on shrimp health and physiological functions, economic considerations and commercial applications of BFT‐based shrimp aquaculture, and the major challenges facing shrimp farming in biofloc systems.

“…Biofloc technology in tilapia ponds can provide 50% of the protein consumed by the fish (Avnimelech, 2007) and when used as a protein source in shrimp feed, microbial floc meal showed the same results or even outperformed soybean or fishmeal ingredients (Kuhn et al, 2009, Kuhn et al, 2010Bauer et al, 2012). Biofloc systems have been mainly used in freshwater ecosystem and for herbivorous organisms but recent studies included mullets and pacific shrimp (Legarda et al, 2019). The successful application of biofloc technology, however, requires knowledge of the system, close monitoring to maintain appropriate C:N ratios and microbial densities and upscaling from laboratory to economic application (Kuhn et al, 2010;Hende et al, 2014).…”

Aquaculture is one of the fastest growing food production sectors and has great potential for food security and livelihoods. However, it generates concerning consequences for the environment, including chemical and biological pollution, disease outbreaks, unsustainable feeds and competition for coastal space. Recent investigations are focusing on sustainable techniques (e.g., polyculture, offshore facilities) to improve the relationship between the industry, environment and society. This review provides an overview of the main factors of ecological concern within marine finfish aquaculture, their interactions with the environment, and highlights sustainable alternatives that are currently in use or development. Adequate environmental monitoring and location of farms, the reduction and exploitation of wastes and chemicals being used is crucial to ensure the growth and continuity of aquaculture production.
