The present invention relates to bacterial probiotics useful in aquaculture. Specifically, it discloses a selection of non-hemolytic, proteolytic, stress-tolerant bacterial strains with enhanced quorum- quenching capabilities. Moreover, the method allows detection of novel species of bacteria whose probiotic attributes could be massive for aquaculture.

The species demonstrated significant efficacy in improving the health and growth performance of Nile tilapia juveniles. Specific growth rates and weight gain, and improved feed conversion ratios without adverse effects on fish health were observed. The gut microbiome was positively influenced by promoting beneficial bacteria while reducing harmful (opportunistic) species, leading to improved immune modulation. Survival rates were significantly boosted during a pathogenic challenge, and key immune genes were upregulated, indicating stronger local immune defenses. These findings show that the selected probiotic species offer substantial benefits for growth, feed efficiency, and disease resistance, emphasizing their potential for widespread application as probiotics in aquaculture.
