“…Abiotic factors, including temperature, oxygen, pH, alkalinity, light exposure, total nitrogen, ammonia, nitrite and nitrate, also play a similar role in shrimp production in BFT systems (Hostins et al 2015;Pi erri et al 2015;. Some other culture conditions, such as the addition of carbon source (to maintain appropriate C/N ratio), water exchange and rearing substrates, are also of prime importance for optimal performance of shrimp and prawn in biofloc systems (Schveitzer et al 2013a;Huang et al 2017;Olier et al 2020). These factors are highlighted in the following sections.…”

“…Substrates also reduced ammonia and nitrite concentrations, especially at higher stocking density. The addition of substrates significantly reduced ammonia concentration, stimulated nutrient recycling, enhanced natural food production and availability and increased growth performance and yield of white shrimp L. vannamei in BFT system (Audelo-Naranjo et al 2012;Olier et al 2020). It is evident from these studies that the addition of substrates can save dietary protein without adversely affecting growth rates or body composition of L. vannamei reared in biofloc systems.…”

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.

Intensification of the shrimp sector, also referred to as vertical expansion, has been predominately driven by consecutive incidences of global disease outbreaks, which have caused enormous economic loss for the main producer countries. A growing segment of the shrimp farming industry has opted to use production systems with higher density, biosecurity, and operating control to mitigate the risks posed by disease. However, successful super-intensive shrimp production is reliant on an advanced understanding of many important biological and economic parameters in the farming system, coupled with effective monitoring, to maintain optimal production. Compared to traditional extensive or semi-intensive systems, super-intensive systems require higher inputs of feed, energy, labor, and supplements. These systems are highly sensitive to the interactions between these different inputs and require that the biological and economical parameters of farming are carefully balanced to ensure success. Advancing nutritional knowledge and tools to support consistent and efficient production of shrimp in these high-cost super-intensive systems is also necessary. Breeding programs developing breeding-lines selected for these challenging super-intensive environments are critical. Understanding synergies between the key areas of production systems, nutrition, and breeding are crucial for super-intensive farming as all three areas coalesce to influence the health of shrimp and commercial farming success. This article reviews current strategies and innovations being used for Litopenaeus vannamei in production systems, nutrition, and breeding, and discusses the synergies across these areas that can support the production of healthy and high-quality shrimp in super-intensive systems. Finally, we briefly discuss some key issues of social license pertinent to the super-intensive shrimp farming industry.

“…The intensive marine shrimp farming using biofloc technology (BFT) has been presented as an alternative to traditional semi‐intensive systems, which usually use large land areas and large volumes of water, in addition to facilitating introductions of pathogens into the nurseries (Crab et al, 2007; Samocha et al, 2007; Krummenauer et al, 2010; Wasielesky et al, 2013; De Melo Filho et al, 2020; Olier et al, 2020; Pinto et al, 2020). The BFT farming method is highly dependent on heterotrophic and autotrophic microorganisms, especially bacteria that contribute to the formation, maturation (microbiological succession process in the culture medium) and maintenance of these systems (Avnimelech, 2009; Emerenciano et al, 2013; Samocha, 2019; Kavitha & Krishna, 2020; Panigrahi et al, 2020).…”

The aim of this work was to isolate, identify and characterize microorganisms present in intensive nursery of Penaeus vannamei during the spontaneous generation of the biofloc and to verify among the isolates, beneficial strains for the intensive cultivation of shrimp under biofloc conditions. 91 strains were isolated and identified by molecular taxonomy. Then, the strains were analysed for the presence of the aiiA gene responsible for the inherited transmission for the production of lactonase.Only Exiguobacterium acetylicum presented the expressed aiiA gene. E. acetylicum was tested for its proteolytic, amylolytic and lipolytic inhibition activity. Inhibition capacity against pathogenic bacteria was 1.47 mm, 2.0 mm and 1.5 mm halo for Vibrio alginolyticus V. harveyi and V. parahaemolyticus, respectively. The mass production process of the E. acetylicum inoculum was standardized at a concentration of 1.58 x 107 CFU/ ml and was applied in two treatments with three replicates each. One group received a weekly application of the inoculum while another group received a biweekly application. A control group received no application of the inoculum. Then, the effect of enriching the intensive culture medium for P. vannamei with E. acetylicum under biofloc conditions was evaluated. At the end of the 21-day trial, the survival and average productivity were statistically higher in the groups that received the application of the bacterial inoculum. The data suggest that the presence of E. acetylicum bacteria in the growth phase of P. vannamei significantly increased survival (90.9 ± 6.0%) and productivity (1.42 ± 0.16 kg/m 3 ).
