Grass carp is a typical herbivorous fish that begins to graze at 5 cm body length. For grass carp weighing over 250 grams, the amount of herbivores per day can reach 125 grams to 180 grams. When grass grass is fed to grass carp, we must put a good four off:
First, more fresh grass fed fresh grass nutritious, less cellulose, grass carp like eating, easy to digest, can make grass carp grow faster, less illness, can reduce the amount of feeding, reduce the cost of farming, improve 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 rye grass, Sudan grass, etc., and collect wild young tender grass. We must also observe grass carp eating. Grasses that prefer eating should be fed more to meet the needs of grass carp growth and development; anorectic fodder should not be fed or fed as little as possible.
The second is to reduce the feeding of aquatic plants. According to the expert test of aquatic products, grass carp eats 15 kilograms of terrestrial aquatic plants and can grow 1 kilogram of meat; and raw water plants need 60 kilograms to 80 kilograms to grow 1 kilogram of meat. Therefore, in the case of insufficient aquatic aquatic plants, little or no aquatic plants can be fed.
Third, according to the different size of the fish mouth feed different grass grass carp during the juvenile period, the mouth is small, can not feed thick, hard fodder, should vote Saliva, duckweed, etc., or the fresh grass side of the grass after the broken Hey. Later, as the fish age gradually increases, the fish's beak also increases, and the transition to feeding conventional fresh grass can be achieved.
Fourth, the method of feeding should be properly fed to the grass carp, every day should be regular, sufficient, uniform feeding, and strive to spread the forage, let the fish eat, eat well, eat evenly, in order to improve the breeding effect. According to the weather, water quality and fish activity, etc., the amount of feed should be adjusted to meet the needs of fish for forage. Strictly prohibit the feeding of forages that have been stored for too long and deteriorated and prevent the fish from becoming infected.
