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. It is forbidden to feed forage that has been stored for a long time and is moldy and deteriorated, so as to avoid fish being infected with diseases.
