The first is to feed more fresh grass. The fresh grass is rich in nutrients, less cellulose, and easily digested. Grass carp eats fresh grass fodder, which can make grass carp grow faster and less. It can also reduce the amount of feeding, reduce breeding cost, and increase economic efficiency. Therefore, fresh fodder should be used as far as possible to feed grass carp. The type of forage material should be long-leaved young tender grasses with parallel veins. It is not appropriate to feed grassy fish with an anorexia-like web of veins. It is better to feed ryegrass, Sudan grasses, etc., and wild young grasses. Usually, we must observe the grass carp eating grass, grass carp like grass should be fed more to meet the needs of grass carp growth and development; grass carp anorexia grass should not be fed or fed 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 to feed different fodder according to 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 and the diameter gradually increases, the transition to conventional fresh forage can be made.
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 weather, water quality and fish activity and other specific conditions to adjust the amount of feed to meet the needs of grass carp 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.
Most products of Fluorine-Containing Benzaldehyde are a pale yellow liquid. They are playing an important role in fine chemical intermediates, is used as the main raw material for the synthesis of a variety of pesticides, pharmaceuticals, surfactants, polymer monomer mildew. As used in medicine synthesis antihypertensive drugs, antipyretic analgesic anti-inflammatory drugs, anti-cancer drugs, muscle relaxation drugs for synthesizing fluorine cypermethrin, fluorine chlorobenzene daisy cool in pesticides, fluoride and styrene, wherein the polymer of styrene monomer to fluorine can be widely used in the manufacture of the recording material, a thermoplastic resin coating, liquid crystal materials. Currently new miticide is effective pesticide products which is the main raw material of Fluorine-Containing Benzaldehyde.
