“…The results indicate that BX-13 is more likely to form and accelerate biofloc formation in aquaculture water. The same results have been confirmed in recent studies (Kasan, Ghazali, Ikhwanuddi, & Ibrahim, 2017;Luo et al, 2016;Pacheco-Vega et al, 2018).…”

A high bioflocculant‐producing bacterial strain BX‐13 isolated from an intensive fish pond by multiple subcultures and measured through primary screening and rescreening using kaolin. The strain BX‐13 was identified to belong to the same branch as Bacillus subtilis by morphological, physiological and biochemical, 16S rDNA gene sequencing, Blast homology search and multiple sequence alignments. The bioflocculation potential of BX‐13 and Rhodococcus erythropolis was compared, using water from the intensive pond where BX‐13 was isolated. The results showed the number of colonies in the BX‐13 treatment was higher than that of the R. erythropolis treatment from day 10 to the end of the experiment (p < 0.05). The numbers of both BX‐13 and R. erythropolis in the water body peaked on day 15, with 2.23 × 107 cfu/L and 9.90 × 106 cfu/L respectively. The bioflocculation volume (BFV) in water increased and then stabilized in both BX‐13 and R. erythropolis treatments. The BFV in BX‐13 peaked on day 25 (52.13 ml/L) and R. erythropolis peaked on day 30 (22.63 ml/L). At the end of the experiment, the BFV of the BX‐13 treatment was higher than the R. erythropolis treatment (p < 0.05). In conclusion, B. subtilis BX‐13 has a very strong flocculation effect, and merits further research into its application for water quality regulation in aquaculture systems.

“…For example, Bacillus, gram-positive, rod-shaped beneficial bacteria, are among the most dominant groups in the microbial communities in bioflocs (Panigrahi et al 2019c), which may play an important role as a probiotic in shrimp farming. The presence of Bacillus can lead to several benefits to farmed shrimp, including improving growth rates, survival, feed efficiency, immunity and disease resistance (Adel et al 2017;Pacheco-Vega et al 2018;Panigrahi et al 2020c). Bacillus-contained bioflocs were found to improve immunity in Indian shrimps P. indicus (Panigrahi et al 2020c).…”

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.

“…Probiotics are getting more and more attention in promoting animal growth and prevention of diseases in aquaculture (Zhao et al 2018), and adding probiotics to the feed or the breeding environment is always the main approach. Good application practice might masked adding probiotics is bene cial to improving water quality (Pacheco et al 2018). The intestinal tract is a complex ecosystem, which is a haven for countless diverse bacterial populations that have been shown to have effects on the host's immunity or nutrient processes (Rungrassamee et al 2013).…”

Shrimp production is the second ranked of the most-traded production in these decades and the whiteleg shrimp Litopenaeus vannamei is the sixth most cultured species. Probiotics are alternative strategy for the promotion of growth and prevention of diseases in aquaculture. To confirmed the effects of the probiotics on development and microbial community of L. vannamei larvae during different development stages, five kinds of probiotics (108~109 CFU/g ) were added into the shrimp larvae rearing environment, and the effects of probiotics on bacterial community and water quality, larval growth and immune index were determined from nauplius larval stage to post larval stage. Results suggested that probiotics treated groups showed larger survival rate than the control groups from Z1 stage to P5 stage. Lactobacillus could improve the larvae’s survival ability, especially in the larval stages M2, M3, P1, P5 stage. It was confirmed that probiotics could promote the growth and development of shrimp larvae and prevent the incomplete molting in their growing process, particularly for EM-treated group. Results suggested that all the probiotics-treated groups had shown significant decreasing trend in the quantity of vibrios, except for the SA-treated group.And different probiotics could inhibite vibrios in different life periods. Amount these probiotics, LA, EM and PB had shown the best effects, including improving survival rate of the larvae, promoting the larval metamorphosis, reducing the quantity of vibrios and NH4-N and NO2-N levels, and increasing bacterial diversity.
