Abstract
Negative impact due to continued usage of antibiotics in aquaculture for growth
promotion and disease control has necessitated research on alternative strategies such as
development of probiotic strains, immunostimulants and vaccination. In this study, the
probiotic effect of a Bacillus spp. on the growth and survival of postlarvae (PL) of
Macrobrachium rosenbergii was studied. The Bacillus spp. under investigation was introduced
in to the PL through culture tank water, feed and both. Changes in the bacterial load and
flora, weight gain, percentage survival and changes in water quality parameters such as pH,
dissolved oxygen, nitrite and ammonia were studied for a period of three months. There
was no significant variation in the survival and weight gain of the PL of the experimental
groups. However considerable improvement was noticed in the water quality parameters such
as nitrite and ammonia concentration of the culture water in the experimental groups
compared to the control group
