Furthermore, some other bacteria consists of several strain Bacillus,
B. subtilis, B. cereus, V. pelagius, V. mediterranei, A. media, Pseudomonas and Thalassobacter utilis also can be
used as probiotics or biological control againts Vibrio also in turn as a potent growth promoter, immuno enhancer,
improve the health and survival for P. monodon postlarvae. This report is substantiated in this research, by a positive
correlation between the negative existence of V. harveyi in the death postlarvae of P. monodon. B. pumilus naturally
constitute a part of the bacterial flora of the shrimp intestinal tracts
