Abstract

In recent years, research on the use of probiotics and prebiotics around the world has shown promising results. Increase on the use of probiotics may lead to identify microorganisms that may have beneficial effects on the bacterial flora of the gut in fish. Prebiotics and probiotics are used primarily to feed that are resistant to the enzymes in the body and thus become a place for the proliferation of intestinal micro-flora. Although the use of prebiotics in the aquaculture industry is still not common, but the benefits can be applied to resistance at high temperatures and long residence time in pellet production line. The purpose of using these natural products and their effects on the activity of microbes in the digestive tract through the consolidation of good microbes and prevent the accumulation of harmful bacteria and are looking for help of fish health studies is compared to described the characteristics of intestinal flora of dominant fish. Probiotics and prebiotics function mechanisms and effects on intestinal ecosystem, evaluating the safety and health of aquatic animals and it is necessary for their life. To illustrate and to optimize these relationships of probiotics and prebiotics, it is dependent of separate studies on any dietary needs grow. In this article the microbial ecology of the gastrointestinal tract and immune system of fish, as well as the potential challenges of application and use of probiotic and prebiotics in fish farming and reviews briefly mentioned.
