Grass carp eats a lot and often eats duckweed and aquatic plants. Grass carp will choose some tender grass during its growth. Because young grass has more protein and less cellulose, it is easy to digest and absorb. Grass carp grows fast and gets sick less after eating, and feeding feed can also reduce the breeding cost and improve the economic benefit. 1. Grass carp feed

1. Grass or various aquatic plants are mainly fed. In addition to barnyard grass, reed grass, bitter grass and POTAMOGETON crispus, artificially planted alfalfa, Sudan grass, ryegrass and other high-quality and high-yield green feeds can also be fed.

2. All kinds of weeds, vegetables, beans, melons, stems and leaves of corn are good feeds for grass carp.

The amount of feed should be flexibly controlled according to the weather, fish feeding and water quality, and it is better to eat it before evening every day. In the hot summer season, grass carp should be strictly prevented from eating night grass.

3. At about 4 pm every day, the compound granular bait should be fed at 1.5% of the weight of pond fish to supplement nutrition and domesticate centralized feeding. The puffed granular bait for grass carp is very effective in combination with green feed. This bait can not only meet the needs of grass carp growth, but also save a lot of labor, and is beneficial to purifying water quality and preventing fish diseases.

4. The forage should be long Julia tender grass with flat veins, and it is not suitable to feed grass carp with netted veins. It is better to feed the cultivated ryegrass, Sudan grass and wild long-leaved tender grass.

5. In case of large-scale farming, it is necessary to feed some feeds. Rice bran, wheat bran, bean cake and fish meal are the main raw materials, mainly granular feed, and the protein content of the feed is 28-32%, supplemented by some turquoise feeds. Feeding twice a day, continuous feeding of granular feed for a period of time needs to stop for a week, and vitamins and other drugs should be added to the feed at ordinary times to avoid grass carp from suffering from hepatobiliary syndrome. Second, the feeding method of grass carp feed

1. Mainly feed pellet feed with protein content of 28 ~ 32%, supplemented by turquoise feed.

2. Feed should follow the principles of "coarse before fine" and "four decisions and four observations". Generally, it should be fed twice a day, and it is appropriate for grass carp to eat within 2 hours and eat 8% full.

3. After feeding granular feed continuously for a period of time, stop feeding granular feed for one week, and feed raw grain feed at intervals.

4. Pay attention to adding vitamins and other drugs in the feed at ordinary times to avoid a large number of deaths caused by diseases such as hepatobiliary syndrome in grass carp.
