“…Similar results were obtained by Lara et al . (2017b) on L. vannamei juveniles (0.89 g) fed a test diet at a daily rate of 0, 0.6, 1.2 and 1.8% bw in the presence or absence heterotrophic flocs. A 1.2% feeding level, in the presence of microbial biofloc, was sufficient for optimum shrimp performance.…”

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.

“…These increases have been limited by several factors such as diseases, rearing limitations, or competition for culture areas by other industries (S. M. Moss et al, 2001). Several studies have focused on improving the new technologies necessary to increase shrimp production (Krummenauer, Poersch, Fóes, Lara, & Wasielesky, 2016; Lara, Honda, Poersch, & Wasielesky, 2017; W. J. Wasielesky et al, 2013; Zemor, Wasielesky, Fóes, & Poersch, 2019).…”

“…Krummenauer et al (2016) tried to solve this problem by altering the water volume in culture to lower depth (shrimp/m 3 ) in order to increase the yield (kg/m 3 production), which represent an option that could lead to other risks such as nitrite toxicity or solids accumulation. In this sense, shrimp behavior permits the increase of area by the application of substrate structures that allow shrimp to graze and diminish stress (Ballester et al, 2018; Ferreira, Lara, Wasielesky, & Abreu, 2016; Lara, Honda, et al, 2017; K. Moss & Moss, 2004).…”

Searching for potential increases in shrimp yields, this study evaluated the effects of different stocking densities on water quality and production performance of juvenile shrimp, Litopenaeus vannamei, reared on a biofloc-dominated system throughout 77 days. The organisms (1.27 ± 0.54 g) were stocked at three densities, 400 (T400), 500 (T500), and 600 (T600) shrimp/m 2 corresponding to 500, 625, and 750 shrimp/m 3 , with three replicates each, in nine 35 m 2 tanks with 28 m 3 of workable volume inside a greenhouse. Shrimp were maintained at optimal conditions for the species with an average temperature of 28.9 ± 0.1 C, dissolved oxygen average above 6.0 mg/L, and pH above 7.3. Significant differences in yields (3.52 ± 0.05, 4.02 ± 0.06 and 4.22 ± 0.40 kg/m 2 or 4.39 ± 0.07, 4.48 ± 0.08, and 5.27 ± 0.49 kg/m 3) were observed between treatments (T400, T500, and T600, respectively), and for final mean weights (12.3 ± 5.53, 12.2 ± 3.89, and 10.2 ± 3.49 g, respectively). These results suggest that 500 shrimp/m 2 or 625 shrimp/m 3 is the optimum stocking density for Biofloc Technology culture under the defined study conditions.

“…Biofilms used for aquaculture have shown positive effects on the production performance, water quality, economic profitability, and, therefore, sustainability (Lara et al., 2017; Shilta et al., 2016). However, there is scarce information about the taxonomic profile of the microbial communities thriving in these culture systems and even less information about their metabolic functions.…”

Bacterial communities and predicted nitrogen metabolism of heterotrophic‐ and probiotic‐based biofilms used for super‐intensive indoor shrimp culture

et al. 2020

Biofilm-based aquaculture systems constitute a promising alternative for intensive shrimp rearing. Microorganisms forming biofilms can recycle the nitrogen compounds the production units improving the water quality while using zero or limited water exchange. This study aimed to compare the taxonomic profiles and the predicted functions related to the transformation of nitrogenous compounds between a heterotrophic-(HtB) and a probiotic biofilm (PrB), and the effect of these on the water quality and the productive response of cultured shrimp. Libraries of the 16S-rRNA gene (V3-V4 region) were prepared and sequenced to be used as a taxonomic biomarker. Analysis of metagenomic datasets revelated that genera Halomonas, Planctomycetes and Rhodopirellula were the most abundant genera in HtB; meanwhile, Bacillus, Halobacillus and Flavobacterium dominated in PrB. Regarding nitrogen metabolism, the proportion of genes encoding enzymes catalyzing the six pathways shaping the nitrogen metabolism showed differences between biofilms, which could also explain the difference in water quality between treatments. Concerning the productive response of shrimp, no significant differences were detected except for survival, which was higher in PrB. Finally, the results suggest that biofilms harbour functions for nitrogen metabolism, including dissimilatory nitrate reduction, assimilatory nitrate reduction, denitrification, nitrification, nitrogen fixation and anammox; however, the balance of these functional capabilities seems to be relevant to maintain water quality.
