Efficient and Effect of Dietary Components on The Gut Microbiota of Aquatic Fishes – By Hydro Chemistry – Modeling – Information Technology

Numerous studies have reviewed the structure and function of the fish gut in relation to diet^[1]as the gut Microbiota has not been included in these papers, a more discussion is needed. Therefore the main objective of the present review was to summarize the available information regarding the effect of dietary components on the gastrointestinal (GI) Microbiota of fish. It is well known that healthy gut Microbiota is essential to promote host health and well being. The intestinal micro biota of endothermic animals as well as fish are classified as autochthonous or indigenous, when they are able to colonize the host's epithelial surface or are associated with microvillus or as allochthous or transient (associated with digesta or are present in lumen). Furthermore, the gut Microbiota of aquatic animals is more fluidic than that of terrestrial vertebrates and is highly sensitive to dietary changes. In fish, it is demonstrated that [a] Dietary form, [b] Dietary lipid (lipid levels, lipid sources and polyunsaturated fatty acids) [c]protein sources (soybean meal, krill meal and other meal products)[d]functional glycomic ingredients (Chitin and cellulose) [e] nutraceuticals (probiotics, prebiotics, synbioitics and Immunostimulants) [f] antibiotics [g] dietary iron and [h] chromic oxide affect the gut Microbiota in these all, we explain some of them in this paper. Moreover, some information is available on bacterial colonization of the gut enterocytes surface as a result of dietary manipulation which indicates that changes on indigenous microbial populations may have repercussion secondary host microbe interactions. The effect of dietary components on the Microbiota is important to investigate, as the gastrointestinal tract has been suggested as one of the major routes of infection in fish Possible interactions between dietary components and the protective Microbiota colonizing the digestive tract are discussed in this paper
