Grass carp feeding precautions

Grass carp (Ctenopharyngodon idellus) is one of the four major domestic fish in China, and it is a common economic fish species in China. As can be seen from its name, it mainly eats grass, but there are also many things to pay attention to when feeding it, such as what forage to choose to feed. When will it be ready to feed? These problems need to pay attention to, the following pro-agricultural network to bring you grass carp feeding points for attention, together to understand it.

1. Forage selection

Forage should choose long-leaf green grass with parallel veins rather than round-leaf grass with reticulate veins. Now grass carp farming mainly feeds ryegrass, Sudan grass and wild long-leaf young grass. And when feeding, we should carefully observe the grass carp grazing to see what kind of forage it likes and dislike. Feed all those who like it to promote its rapid growth, and those who are anorexic should be fed as little or no as possible.

2. Fresh and tender terrestrial aquatic plants

Try to choose fresh and tender aquatic grass, this is because the fresh and tender forage has less cellulose and is easy to be digested and absorbed by grass carp. If the forage is old and not fresh, there is more cellulose and grass carp is not easy to digest after eating. When choosing to feed, it is best to choose terrestrial aquatic plants and reduce aquatic aquatic plants as much as possible. according to experimental studies, grass carp can grow about 1 jin if they eat about 15 jin of terrestrial aquatic plants, while only about 60-80 jin of aquatic plants can grow, so when terrestrial aquatic plants are sufficient, try not to feed aquatic plants.

3. Feed according to the size of the fish

When feeding, we should also pay attention to the caliber of fish, such as the caliber of young fish is small, it is not suitable to feed coarse and hard forage, it is suitable to feed algae such as duckweed, or cut up the forage to feed. With the growth of grass carp, the caliber increases and slowly transitions to normal forage.

4. Feeding method

Be sure to feed grass carp at a fixed time and in sufficient quantity every day, and spread the forage evenly during feeding, not directly in one place, which can easily lead to the phenomenon of grass carp grazing. Feeding should be best in the morning during the day, feed in the morning, and finish the forage in the evening to prevent the forage from staying overnight and ensure the freshness of the forage. It is strictly forbidden to feed the deteriorated, moldy or contaminated forage, which will increase the incidence of grass carp and infect it with disease.

The above pro-agricultural network for grass carp feeding matters needing attention, grass carp feeding relationship can grow fast and good important point, must pay attention to feeding methods and forage selection, to promote the effect of culture.
