The use of probiotics in aquaculture is proving to be effective in improving disease resistance, nutrition and/or growth of cultured organisms. Three strain of Bacillus sp. was isolated from the intestinal tract of fish and identified by conventional biochemical characteristics and 16S rDNA gene sequence analysis. We studied the probiotic properties of Bacillus sp. The strains studied exhibit antibacterial activity against the different pathogenic tested. Adherence assays revealed that the isolates are fairly adherent. The challenge test on axenic Artemia culture showed that the protection against pathogenic Vibrio was improved. On the basis of these results, we can suggest that the strains studied can be used as potential probiotic candidates for the culture of Artemia.
