This study aimed to investigate the effect of Bacillus aryabhattai (LSG3-7) and Bacillus mojavensis (LSG3-8) on growth performance, antioxidant capacity, and immune response in Rhynchocypris lagowskii (Dybowski, 1869), at the trial and challenge periods. A 630 healthy fish (10.76 ± 0.

This study aimed to evaluate the bacilli isolated from the Rhynchocypris lagowskii intestines and their validity as a probiotic. Three isolates were selected (LSG 2-5, LSG 3-7, and LSG 3-8) and defined by morphological and 16S rRNA analysis as Bacillus velezensis, Bacillus aryabhattai, and Bacillus mojavensis, respectively.

- Probiotics, specifically Bacillus amyloliquefaciens LSG2-8, are evaluated for their impact on the intestinal barrier function in the fish species Rhynchocypris lagowskii.
- A 56-day experiment showed that various concentrations of B. amyloliquefaciens in the diet significantly boosted intestinal digestive and immunity-related enzyme activities compared to a control group.
- Additionally, the study found improved expression of key mRNA levels related to immune function and intestinal integrity, while also indicating a positive effect on gut flora balance and intestinal structure.
