Feeds containing balanced nutritions are ideal for fish normal growth. Feed pellet use various grains such as wheat, corn, bean etc as feed ingredients and can be added with protein, fishmeal, minerals and other liquid nutritions. So it can meet the nutrition needs of fish.
Second, the appearance of feed pellet. The high quality feed pellet has smooth surface and the same pellet diameter. The particle diameter for fish feeds should consider the mouth diameter of fish and should not be too big or too small. The length of feed pellet should be two times of the diameter so as to increase feed intakes and reduce feed waste.
Third, the stability in water. Fish intake feeds slowly so the feed pellet must keep the shape in water for a long time. Fish farmers can take some samples and place them in water to detect the stability before buying feed pellets for fish.
