-The use of biofloc technology (BFT) can improve fish production in regions with low water availability. Therefore, information on dynamics of water quality is essential for success in fish rearing. Thus, the objective of the present study was to evaluate the water quality for Nile tilapia farming in a system without water exchange, during the fingerling stage, using different sources of carbon and C:N ratios. A completely randomized experimental design was used in a 2x3 factorial arrangement, with two carbon (C) to nitrogen (N) ratios (10:1 and 20:1) and three carbon sources (sugar, molasses and cassava starch). The C:N ratio and carbon source affected the variables alkalinity, settleable solids (SS), turbidity and total suspended solids (TSS), showing significantly higher values at C:N ratio of 20:1 (P < 0.05). The best carbon source for microbial floc formation were the molasses and sugar, under C:N ratios of 10:1 and 20:1. The stability of the monitored water quality parameters occurred from 6 to 7 weeks of rearing. The growth performance of Nile tilapia in BFT system fertilized with different organic carbon sources was not significantly different (P < 0.05) between treatments. The use of molasses to fertilize BFT systems can reduce costs of production in regions where this product is available. RESUMO -O uso da tecnologia de biofloco (BFT) pode contribuir para a produção de peixes em regiões com reduzida água. Portanto, compreender a dinâmica da qualidade da água é essencial para o sucesso do cultivo de peixes. O objetivo do presente estudo foi avaliar a qualidade da água no cultivo de tilápia do Nilo em sistema sem troca de água, durante a fase de alevinagem, utilizando diferentes fontes de carbono e relações C:N. O delineamento experimental utilizado foi o arranjo fatorial 2x3, contendo duas relações carbono (C) e nitrogênio (N) (10:1 e 20:1) e três fontes de carbono (açúcar, melaço e amido de mandioca). Ambas as relações C:N e fontes de carbono influenciaram as variáveis alcalinidade, sólidos sedimentáveis (SS), turbidez e sólidos suspensos totais (SST) demonstrando valores significativamente mais elevados na relação C:N 20:1 (P < 0,05). As melhores fontes de carbono para a formação de flocos microbianos foram observados na utilização do melaço e açúcar na relação C:N de 10:1 e 20:1. A estabilidade dos parâmetros de qualidade de água monitorados ocorreu entre a 6 e 7 semanas de cultivo. O desempenho de tilapia do Nilo em sistema BFT fertilizado com diferentes fontes de carbono orgânico não foi significativamente diferente (P < 0,05) entre os tratamentos. A escolha de melaço para a fertilização do sistema BFT também pode ajudar a reduzir o custo de produção em regiões onde há disponibilidade deste produto. Palavras-chave:Oreochromis niloticus.

“…Many sources of carbon have been tested in BFT systems, such as grain, sugar, molasses, sugarcane bagasse, chopped hay and tapioca. The sources must be chosen considering their cost and local availability (HARGREAVES, 2013;FUGIMURA et al, 2015;SERRA et al, 2015;AHMAD et al, 2016).…”

“…In a BFT system resulted in greater abundance of Chlorophyceae and Cryptophyceae (Du et al 2018). Chlorophyll a was also found to accumulate more in BFT treatments utilizing molasses as an organic soluble carbon source, signifying an abundance of microalgae communities in the system (Ju et al 2008;Fugimura et al 2015). The abundance of these phytoplankton communities may result in greater levels of crude lipids and fatty acids in the resulting bioflocs and thus increase the nutritional value of bioflocs (Ju et al 2008;Ballester et al 2010;Emerenciano et al 2012;Godoy et al 2012).…”

“…Molasses is a less expensive organic carbon that has also been demonstrated to be effective at stimulating heterotrophic assimilation of NH þ 4 -N (Burford et al 2004;Emerenciano et al 2012). For example, using soya bean and sugarcane molasses as external organic carbon sources maintains water quality in the super-intensive culture of L. vannamei in BFT systems (Fugimura et al 2015;do Espírito Santo et al 2017). Cellulose (C 6 H 10 O 5 ) x is a polysaccharide of glucose units occurring naturally in fibrous products (Merriam-webster 2020).…”

“…Therefore, the cost-effectiveness of these materials must be evaluated for each category of carbon sources currently applied in BFT systems. However, studies describing the cost of organic carbon sources are scarce in the current stock of literature (Fugimura et al 2015;Zhang et al 2016). Both the carbon source and the addition strategies determine the total cost of organic carbon sources used for a given BFT aquaculture system.…”

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.
