“…Many natural products and wastes have been used as carbon sources for BFT-based shrimp farming, including sugarcane molasses, glucose, sucrose, rice bran, wheat bran, starches and flour (see Table 1 for review). Even biological degradation polymers (BDPs), such as poly-caprolactone (PCL) and b-hydroxybutyric (PHB), have been tried, with varying results (Luo et al 2019). It should be emphasize, however, that the effects of carbon addition depend on the carbon source, quality and quantity, time and frequency of application, total ammonia nitrogen (TAN) level in the water, supplemental feed and stocking density of farmed shrimps.…”

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.

“…Supplying water-soluble substrates as organic carbon has been criticized for its complexity and cost, as additions should occur a few times per day or per several days with careful calculation and constant supervision to avoid overdosing or starvation (Serfling 2006;Emerenciano et al 2012;Luo et al 2017;Luo et al 2019a). Additionally, dissolved oxygen is required for bacteria to decompose organic matter substrates (Azim et al 2007).…”

“…Although biofloc systems are expected to be purely heterotrophic, activities of chemo-autotrophic bacterial population have been observed (Nootong et al 2011;Luo et al 2019aLuo et al , 2020. Therefore, populations of these two groups of bacteria may both find ideal growing conditions in BFT systems.…”

“…The authors also found that, compared with rice bran and sucrose treatments, glycerol treatment resulted in a consistently lower level of nitrite, which all resulted in greater concentrations at certain points. By comparing glucose and PHB as extra carbon sources for BFT systems, Luo et al (2019a) observed that PHB was better at maintaining NO À 2 at a relatively low level (0.16 AE 0.24 mg L −1 ) compared with the levels resulting from glucose (0.20 AE 0.22 mg L −1 ) and a combination of glucose and PHB (0.19 mg L −1 ). However, in the study by Deng et al (2018), unlike the noticeably lower levels of TAN observed in carbon-supplemented treatments described earlier, levels of NO À 2 were not significantly different in the carbon-supplemented groups compared with the control group with no carbon treatment.…”

Biofloc technology (BFT) systems have been driven towards increased sustainability in the last decade. BFT depends on maintenance of the optimal carbon-to-nitrogen (C/N) ratio through supplementation with organic carbon sources. The types of carbon sources and addition strategies are critical considerations in BFT systems. Thus for the purpose of this review, a thorough search of the literature was conducted to gather relevant information from reliable sources, ranging from reputable journals to books and useful reports in the field of BFT. Keywords used for the literature search include: 'biofloc technology systems', 'carbon sources', 'solid carbon sources', 'effects of carbons sources', 'carbon source addition strategies', 'nutritional quality of bioflocs', 'carbon sources and water quality', 'C/N ratio in BFT', and 'carbon sources and bacterial community'. Among the several peer-reviewed articles, books and technical reports consulted, 147 (dated from 1987 to 2020) were relevant for the preparation of this review. The current review thus examines the subject of supplemental carbon sources in BFT systems and discusses the various effects of their application with respect to the culture organism, microorganisms, water quality and the nutritional quality of flocs. The benefits and challenges associated with the types of carbon sources used in BFTs are also presented. Suggested organic carbon sources and their addition strategies are provided, and further research directions are proposed.
