What are the precautions for feeding grass carp?
Grass carp is one of the four major domestic fish species in China and a common economic fish species in the country. As its name suggests, it mainly feeds on grass, but there are many things to pay attention to when feeding it, such as what kind of grass to choose for feeding? When is the best time to feed? These questions all need attention. Below, Qinnong Web brings you the precautions for feeding grass carp. Let us learn about them together.
1. Forage selection
Forage should be selected from long-leaf tender green grasses with parallel veins, not from clustered-leaf forages with netted veins. Currently, grass carp farming mainly feeds on ryegrass, Sudan grass, and wild long-leaf tender grass. When feeding, carefully observe how the grass carp eats the grass, and see which forage it likes or dislikes. Feed more of what it likes to promote rapid growth, and feed as little as possible or not at all of what it dislikes.
2. Fresh tender terrestrial aquatic plants
Try to choose fresh tender aquatic plants, because fresh tender forage has less cellulose and is easily digested and absorbed by grass carp. If the forage is old and not fresh, it contains more cellulose, which is not easy for grass carp to digest after eating. When choosing feed, it is best to choose terrestrial aquatic plants and minimize feeding with aquatic aquatic plants. According to experimental research, grass carp eating about 15 jin of terrestrial aquatic plants can gain about 1 jin, while eating about 60-80 jin of aquatic aquatic plants can gain 1 jin. Therefore, when terrestrial aquatic plants are sufficient, try not to feed aquatic aquatic plants.
3. Feed according to the size of the fish
When feeding, also pay attention to the size of the fish's mouth. For example, fry have smaller mouths and should not be fed coarse, hard forage. They are suitable for feeding on algae such as duckweed, or the forage can be chopped and fed. As the grass carp grows and its mouth becomes larger, gradually transition to normal forage.
4. Feeding method
When feeding, be sure to feed at a fixed time every day and in sufficient quantity so that the grass carp eat their fill. When feeding, scatter the forage evenly, and do not scatter it directly in one place, as this can easily cause grass carp to compete for food. Feeding is best done in the morning during the daytime. If fed in the morning, the forage can be eaten up by evening, preventing the forage from being left overnight and ensuring the freshness of the forage. It is strictly forbidden to feed deteriorated, moldy, or contaminated forage, as this will increase the disease rate of grass carp and cause them to become infected with diseases.
The above are the precautions for feeding grass carp brought to you by Qinnong Web. When feeding grass carp, this is an important point that affects whether they can grow quickly and well. Be sure to pay attention to the feeding method and the choice of forage to promote the farming results.
