Two separate experiments were performed to evaluate possibility of using the probiotic bacteria as supplemental feed for Artemia franciscana. Artemia was stocked at density of 100 individual/L and lasted 15 days. Bacteria were added to the culture medium at concentration of 10⁶ CFU/mL and applied every 3 days for both experiments. In the first experiment, it consisted of 4 treatments namely the control was not supplemented with the bacteria and 3 other treatments were supplemented different Bacillus strains B37 (Bacillus sp.); B41 (Bacillus amyloliquefaciens) and B67 (Bacillus subtillis) in the culture medium at density of 10⁶ CFU/mL and applied every 3 days. It was observed that survival and total length of Artemia in the three supplemented treatments were in the ranges of 80.3 85.7% and 8.6-9.5 mm, respectively, and significantly higher (PBacillus strains to the culture medium enhanced the fecundities of Artemia females. Especially, supplementation of Bacillus B37 strain gave the best performance of Artemia, followed by B41 strain and B67 strains. In the second experiment, there were four treatments including the control without supplementing bacteria and the three remaining treatments were supplemented with B37 strain, and two commercial probiotic products (Tadobacillus and BZT). Results showed that survival of Artemia at day 15 were 65.3-81.7%, and total length attained 7.2- 9.3 mm, of which the B37 treatments gave the highest values, and statistically differed (PArtemia females in the B37 treatment was superior to the remaining treatments. This indicated that the B37 Bacillus sp.  could be the best probiotic bacteria used as supplemental feed for Artemia.
