abstract
The growing demand towards the environment friendly culture practices is motivating researchers to focus on certain experiments on the probiotics and its application in aquaculture. Probiotics are the microbial feed supplements or water additives that improve the culture media and the health of the cultured organisms. Researchers found the beneficial effects of probiotic micro-fauna as a promoter of growth, survival, health, etc. to the host. It has been proven that the bacterium which is a pathogen for a species may bring benefits to the other species. They produce anti-microbial substances such as anti-bacterial, anti-viral, anti-fungal, etc. which provide protection to the host from the pathogens. It replaces the use of antibiotics in aquaculture. So, this study aims to give a clear idea on the beneficial effects of probiotics in aquaculture.
