Monopterus eels are very suitable for farmers to initially get involved in the breeding industry, because breeding is relatively easy. Monopterus eels are generally cultured in cages to reduce the outflow of eels and facilitate fishing. By following the following six steps, you can easily achieve cage culture of eels. 1. Building Chiguan

Scientifically building eel ponds is the basis for eel breeding. Generally, cement and brick structures are used to build semi-underground ponds, with sizes ranging from 6 to 20m2. It is advisable to lay the bottom surface with concrete and the pool depth is about 1-1.5m. In order to prevent the eels from escaping, the corners of the pool are generally built in an arc shape, and the eaves of the pool extend inwards.

Set up an inlet, drainage outlet and overflow outlet. The water inlet is generally 30-40cm above the water surface. The drainage outlet is installed below the mud layer line to drain all the pool water. The overflow outlet is generally located higher than the mud surface. at 20cm. The drain outlet and overflow outlet should be located on the opposite side of the water inlet, and each water outlet should be equipped with a metal mesh to prevent escape. 2. Environmental issues

Since eels like caves that are half water and half empty, the eel pond should have both water and land. This problem is usually solved by setting up a mud bank. The mud ridge is narrow at the top and wide at the bottom, with a bottom width of 40cm and a height of about 40cm. There are connected mud ditches between adjacent mud ridges. The width and depth of the ditch are about 30cm. Pay attention to scraping off the soft mud on the bottom when stacking the mud ridges. Then some aquatic plants can be planted on the mud ridge, such as cash crops such as rice and water chestnuts. It would be better if there are suitable Chinese herbal plants.

In addition, in order to block the sun, 2-3 grapes can be planted on the top of the pond according to the size of the eel pond. The vine layout is preferably dense in the west and sparse in the east. You can also plant luffa, gourd and other vines to control the light, especially to block the western sun in summer. In this way, a relatively suitable and stable small ecological environment is created for eels to live. 3. Substrate quality

The bottom layer is paved with waste plant straw. Generally, coarse fiber plant waste with toughness, good air permeability and strong corrosion resistance is selected, and the size is required to be matched. The weight ratio can be The ratio of thick rod: medium rod: broken material is 5:3:2. For example, first lay 1-2 layers of corn stalks, then lay about 20cm thick rapeseed stalks (or bean straw), and then lay 3-5 layers of crisscrossed corn stalks or sorghum stalks on top.

Finally, sprinkle in a layer of rice husk and a layer of quicklime (0.5kg for about 10m2); the middle layer is a harder clay layer for eels to burrow, usually about 30-40cm thick; the top layer can be spread Silt, with a thickness of about 15cm, is sprinkled with a thin layer of quicklime, and finally water is injected for substrate disinfection. 4.
