First, feed more fresh and tender forage. Because the fresh forage grass is rich in nutrition, less in cellulose and easy to digest, it can make grass carp grow fast, get less sick and reduce the feeding amount. It is best to feed forage materials such as artificially planted ryegrass, Sudan grass and friendship alfalfa, as well as collected wild long-leaved tender grass. Anorexia people should not feed grass carp. Also observe the grazing situation of grass carp. Feed more grass you like to eat to meet the needs of grass carp growth and development.
The second is to reduce the feeding of aquatic plants. Grass carp can grow 1 kg meat if they eat 1 kg terrestrial aquatic plants; If you eat aquatic plants, you need to eat 60 kg to 80 kg to grow 1 kg of meat.
The third is to feed different forage according to the size of the fish mouth. Grass carp has a small mouth at the juvenile stage and can't feed coarse and hard forage. Suitable for feeding Cyperaceae, Lemnaceae, etc. Or feed it with fresh long-leaved grass after it is broken. In the future, with the gradual growth of fish age and the increase of fish mouth, we can transition to feeding conventional fresh and tender forage.
Fourth, the feeding method should be proper. Grass carp should be fed regularly, fully and evenly every day, and the grass should be paved well to make the fish full, eat well and eat evenly, so as to improve the breeding effect. It is also necessary to adjust the feeding amount according to the weather, water quality and fish activities to meet the fish's demand for forage. Forage that has been stored for a long time and is moldy and deteriorated is strictly prohibited to prevent fish from being infected with diseases.
