This study aimed to evaluate the effects of the direct supplementation probiotics and glucose into Artemia’s cultured environment. Artemia franciscana from Vinh Chau was cultured at a density of 100 individuals per litre at salinity of 30‰ and fed by Lansy PZ. The experiment included 6 treatments as follow: control treatment (only Lansy); glucose 100 µg.L-1; Bacillus subtilis; Lactobacillus acidophilus; and combined Bacillus subtillis or Lactobacillus acidophilus with glucose 100 µg.L-1. After 15 days of experiment, length of Artemia in the control treatment was lowest (5.24 mm) which was significantly different from other treatments (P<0.05). Survival rate was highest (61%) in treatment of glucose 100 µg.L-1. Artemia in treatment contained Bacillus subtilis and glucose 100 µg.L-1 presented a maximal length (7.47 mm). Matching rate of Artemia was also highest in this treatment (43%). Bacillus supplementation together glucose also improved the fecundity of Artemia (48 offsprings per female). On the contrast, direct supplemenation of Lactobacillus acidophilus into cultured medium did not showed the positive effects on Artemia.
