Carbohydrate has been primarily used in fish diet as energy source and for their binding properties. It is important in formulated diets because they are cheaper than lipids and proteins. Diets used in fish farming contain high variable amounts of carbohydrate depending on cultivated species. Fish species differs greatly in their ability to digest carbohydrate; this variability reflects anatomical and functional differences of the gastrointestinal tract and associated organs.
