The first is to feed more fresh grass. The fresh grass is rich in nutrients, less cellulose, and easily digested. The grass carp feeds fresh grass, grows faster and less, and can reduce the cost of breeding and increase economic efficiency. The species of forage should be young, tender and tender grasses with parallel veins, and should not be fed with mesh veins. It is better to feed species such as ryegrass, sudangrass and other pastures and collected wild young grasses. Usually, we must observe the grass-grass grazing situation, grass-fed grass should eat more feeding, otherwise should not feed or feed as little as possible.

The second is to reduce the feeding of aquatic plants. According to aquaculture experts, grass carp eats 15 kilograms of terrestrial aquatic plants and can grow 1 kilogram of meat, while eating 60 to 80 kilograms of aquatic plants can grow 1 kilogram of meat. Therefore, in the absence of terrestrial aquatic plants, aquatic plants can be fed with little or no water.

The third is feeding forage based on the size of the fish's caliber. Grass carp is small in larval stage and cannot be fed with thick, hard fodder. Safflower, duckweed, and other forages should be fed or fresh shrubs should be crushed and fed. Later, as the age of the fish increases, the diameter gradually increases, and the transition to feeding fresh grass can be achieved.

Fourth, the method of feeding should be appropriate. To feed the grass carp, it is necessary to regularly, adequately, and evenly feed it every day, striving to spread the forage, allowing the fish to eat full, eat well, and eat well to improve the breeding effect. According to the specific conditions such as weather, water quality and fish activity, the amount of feed should be adjusted to meet the demand of grass carp for forage. It is forbidden to feed forages that have been stored for a long time and that have deteriorated, so as to avoid grass carp infections.
