Stability, physical form diet pellets are very important during consumption and prevention of early leaching into water. In sustainable aquaculture quality of diet is very important, Because about 60% of the total cost is related to production fish diet, diet quality plays a vital role in aquaculture. Therefore, during the preparation of a high quality diet it is necessary to pay attention to cost, stability, physical form and feed requirements. Feed stability could be increased by using binders. So, binders can improve the pellet strength and reduce the corrosion rate during the processing and transport of feed. On the other hand, pellet leaching in water cause the loss of ingredients and reducing the nutritional value of feed. Moreover, deposition the material in the bottom of the pool and their metabolism will increase the BOD in water. So, pathogens and consequently their secondary effects have good condition to grow. The best binders are those that in addition to increase the feed strength can decrease the expenditure and be available. Different types of binders are included: carboxymethyl cellulose, corn starch, sodium bentonite, aqua cube and so on. The aim of the present project was to study the variety of used binders in aquaculture and introduction of the best of them with the optimum efficiency.
