In the summer when grass is used to feed grass carp, pay attention to the following points: First, pay attention to fresh grass and tender grass. The fresh grass is rich in nutrients, less cellulose, and easily digested. Grass carp eats fresh grass and can make grass carp grow faster and less. Can also reduce the amount of feeding, reduce the cost of farming. Improve economic efficiency. Therefore, fresh grass should be used as far as possible when feeding grass carp forage. The second is to pay attention to the quality of the forage and disinfect the forage grass. It is better to choose the long-leaved young tender grass with parallel veins. It is better to feed ryegrass, Sudan grasses, etc., and wild young grasses. At ordinary times, we must also observe the grass carp eating grass. Grass grass fish like to eat more grass should be fed to meet the needs of grass carp growth and development, grass carp anorexia grass should not be fed or fed as little as possible. Third, pay attention to reducing aquatic aquatic feeding According to aquaculture experts, grass carp eat 15 kilograms of terrestrial aquatic plants can grow 1 kilogram of meat, and eat 60 to 80 kilograms of aquatic plants to grow 1 kilogram of meat. Therefore, in the case of terrestrial plants with small foot sources, aquatic plants can be fed with little or no water, and they can be sterilized for 20 to 30 minutes with CH CHUAN 6 mg/L bleach solution. The fourth is to pay attention to the size of the fish according to the different feeding grass feed grass carp at the juvenile stage diameter is small, can not feed thick, hard fodder, should feed saliva, duckweed and other fodder, or smash the fresh long-leaf grass After feeding. Later, as the age of the fish increases, the diameter gradually increases, and the transition to feeding fresh grass can be achieved. The fifth is to pay attention to feeding methods to properly feed the grass carp, every day to regular, sufficient, uniform feeding, and strive to spread the forage, let the fish eat, eat well, eat uniform, in order 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 strictly forbidden to feed forage that has been stored for a long time and that has deteriorated to prevent grass carp infection. Sixth, it is important to pay attention to the prevention of fish disease. Grass carp is prone to outbreak fish disease. In the breeding process, fish disease prevention should be done well. 1 For every 100 kg of grass carp, add 0.5 to 1.0 kg of garlic and chop and add the same amount of salt to the bait. Feed it once every two weeks. 2 Dissolve 0.25 kg of disinfectant in a small amount of water each time. Sprinkle when grass carp concentrates on food. Repeat once every 10 days. 3 Sprinkle lime water once every 10th day in Quanchipia, and use 15 to 20 kilograms for each mu of water.
