“…Bacillus amyloliquefaciens LSG2-8 ISSN (print): 1823-8262, ISSN (online): 2231-7538 could improve the growth performance, antioxidant capacity, immune function and disease resistance of R. lagowskii and be used in aquaculture (Yu et al, 2022). Bacillus amyloliquefaciens LSG2-8 may improve the intestinal barrier function of R. lagowskii and can be used as a feed additive in aquaculture (Yu et al, 2023).…”

Aims:The aim of this study was to analyze the physiological properties, pathogenicity and application of probiotic bacteria to catfish (Clarias sp.) cultivation in vivo. Methodology and results: Probiotic bacteria's physiological characteristics were described using descriptive approaches, whereas experimental methods analyzed pathogenicity tests and the application of the probiotic bacteria in catfish cultivation. The results of bacterial characterization showed that Bacillus safensis strain C251 SA3, Bacillus amyloliquefaciens strain NO10 SA8 and Bacillus australimaris strain IIHR GAPB01 SL1 had bacili cell shape and showed a positive catalase test for all test bacteria except Bacillus safensis strain C251 SA3. The three probiotic bacteria also had negative oxidative-fermentative results, which were able to reduce nitrate and survive in environmental conditions with pH 3-9. Pathogenicity analysis revealed that the three bacteria had the potential to be non-pathogenic or less pathogenic. Bacillus safensis strain C251 SA3 treatment on catfish resulted in the best survival rate of 64% and a 17.5 cm growth in catfish body length by week 13. When Bacillus amyloliquefaciens strain NO10 SA8 was applied to catfish, the survival rate was 32% and the catfish body length increased by 22 cm by week 13. The control treatment revealed that all catfish samples died or had a 0% survival rate, while the application of Bacillus australimaris strain IIHR GAPB01 SL1 revealed a catfish survival rate of 0%. Conclusion, significance and impact of study: Bacillus australimaris strain IIHR GAPB01 SL1 is a potential probiotic bacterium to be applied in catfish food.

To exploit aquatic animals’ feed resources and functional ingredients and additives, this experiment investigated the effects (a 2 × 2 factorial trial) and mechanism of woody plants and probiotics on Nile tilapia. Each treatment group was randomly assigned triplicate nets of 40 fish (initial body weight of 35.04 ± 0.01 g) in 12 tanks for 56 days. Fish were fed four diets, including a CON–CON diet (with no supplementation) and CON–Ba (basal diet + 1 × 107 CFU/g B. amyloliquefaciens), MO-CON (basal diet + 10% Moringa oleifera) and MO-Ba (basal diet + 1 × 107 CFU/g B. amyloliquefaciens + 10% Moringa oleifera) until apparent satiation (2 meals/day). The results showed that the MO diet had a lower feed conversion ratio than the non-MO diets (P<0.05). The weight gain in the Ba group was significantly higher than those in the groups without Ba treatment (P<0.05). Both MO and Ba improved the morphological indices when applied individually (P<0.05). Ba supplementation improved the activities of digestive enzymes (P<0.05). MO significantly upregulated the gene expression of TNF-α, IL-6, IL-10, and C3 in the spleen of Nile tilapia (P<0.05), while Ba significantly upregulated the gene expression of IL-6 and C3 (P<0.05). The microbiological analyses showed that the abundances of beneficial bacteria increased, and the relative abundances of pathogenic bacteria decreased in fish-fed MO. In conclusion, dietary MO and Ba can effectively improve the immunity of Nile tilapia, while Ba can enhance the activities of digestive enzymes. The synergistic effect of MO and Ba on the intestinal microbiota of Nile tilapia promotes growth, thus showing promising application prospects.
