There are many types of probiotics like yeast, Lactococcus, Bacillus and Pediococcus which have shown beneficial effects, however the important probiotic bacteria are Lactobacillus and Bifidobacterium.The possible modes of action are mainly competitive exclusion of pathogenic bacteria, production of inhibitory compounds and also enhancement of the immune system towards the pathogenic infections.In few studies, it has also shown to improve the water quality by controlling the growth of phytoplanktons. In this review, the history of probiotics, their mode of action, applications of probiotics in aquaculture, Interference with Quorum sensing and molecular approach has been presented.
