What vegetable leaves do grass carp like to eat? Detailed explanation of feeding points for farming
Grass carp is one of the four major domestic fish in our country and is widely sold on the market. Our country's grass carp farming history spans over one thousand seven hundred years, but in the past, natural fry from rivers were taken and raised in ponds for food or sale. Only after the founding of New China did grass carp achieve artificial breeding. So when it comes to artificial farming, what vegetable leaves do grass carp like to eat?
I. What vegetable leaves do grass carp like to eat
Grass carp is a typical herbivorous fish. Under natural conditions, the fry feed on zooplankton. Young fish like to eat Wolffia, small duckweed, purple-backed duckweed, Hydrilla verticillata, and so on, while for adult fish, they like to eat Vallisneria, Potamogeton, and so on. Under artificial feeding conditions, in addition to eating aquatic plants, they also like to eat terrestrial plants of the grass family, legume family, and so on. At the same time, they also like to eat artificial bait, such as cakes, bran, wheat bran, and so on.
Because grass carp has simple feeding habits, a wide source of bait, and rapid growth with high yield, it is often used as the main stocking subject for pond farming and lakes, reservoirs, and rivers. Since the success of artificial induced spawning and fertilized hatching technology in 1958, the sources of fry and fingerlings have become easy, and it has become a major intensive farming subject in our country. Grass carp is widely distributed in our country in the plains from Guangdong to the Northeast, except for Xinjiang and the Qinghai-Tibet Plateau, and now it is also distributed in many countries in Asia, Europe, America, and Africa.
II. Key points for grass carp farming
1. When selecting grass carp fry, be sure to observe carefully and choose as much as possible fry with no wounds on the body surface and uniform size.
2. The conditions that a grass carp farming site must have are, first, sufficient water sources; second, a complete power supply facility; and finally, convenient transportation.
3. When feeding grass carp, remember not to put in too much feed at one time, and the speed of putting in feed each time must not be too fast. The feed for grass carp must be guaranteed in quality, so as to reduce the occurrence of grass carp diseases.
4. Generally, in the early morning, the oxygen content in the fish pond is the lowest. During this time period, the farm must artificially aerate the fish pond to ensure the oxygen content in the pond. The water in the fish pond must also be changed regularly, so as to ensure that the water quality in the pond is clean.
