Grass carp is a typical herbivorous fish. Juveniles began to graze from 5 cm in length. Grass carp weighing 250 grams or more can reach 125-180 grams per day. However, when using grass to feed grass carp, pay attention to the following four points:
More fresh grass feed
Fresh grass is rich in nutrients, less cellulose, grass carp likes to eat, easy to digest, can make grass carp grow faster, less sick, can reduce the amount of feeding, reduce the cost of breeding, and increase economic efficiency. Therefore, fresh grass feed should be used as far as possible. 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. To observe grass carp grazing, the grass should be fed more to meet its growth and development needs; anorexia grass should not be fed or fed as little as possible.
Reduce the feeding of aquatic grass
According to fish expert experiments, grass carp eats 15 kilograms of terrestrial aquatic plants and can grow 1 kilogram of meat; while eating aquatic plants requires 60-80 kilograms to grow 1 kilogram of meat. Therefore, in the case of insufficient aquatic aquatic plants, little or no aquatic plants can be fed.
According to the size of fish mouth feed different forage materials
Grass carp in the juvenile period, the mouth is small, can not feed coarse, hard grass, should vote in saliva, duckweed, etc., or the fresh long-grass mash and feeding. Later, as the fish ages gradually increase, the fish's beak also increases, and it is possible to transition to feeding conventional fresh grass.
Feeding method should be properly
To feed grass carp, it is necessary to regularly, adequately, and evenly feed it every day, striving to spread the forage, allowing the fish to eat, eat well, and eat well so as 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.
