The demand for cultured carp species has grown tremendously during the last decade due to their high market value. Probiotics use in aquaculture has gained attention as microbial candidates to maintain the health and the wellbeing of many aquaculture animals. Among the many microbial candidates, probiotic has sporulation capacity that makes them survive harsh environmental conditions, is nonpathogenic and non-toxic when fed to fish, and can produce antimicrobial substances making them more suitable candidates. Present review summarizes the results of probiotic administration on growth performance, gut physiology, intestinal microbiota, immune response and health status of different fin fish as well as shell fish species. Furthermore, this study tries to cover the gaps in existing knowledge and suggest issues that merit further investigations.
