First, the choice of the construction site of Monopterus albus pond

We can make use of some abandoned water bodies that are not suitable for cultivating other fish, or cultivate them in puddles and ponds that are not suitable for planting crops, or stock some Monopterus albus in the water bodies where Zizania latifolia, lotus and water chestnut are planted.

The pond where Xu Jia raises Monopterus albus should be near his residence. Ventilation should be sunny, and the pond should be built where there is water. Warm in winter, cool in summer, plenty of water and clean water.

Second, the shape and size of the eel pond

The shape of eel pond can be designed by beautifying the environment, such as rectangle, square, circle, ellipse and so on. At present, rectangular eel ponds are widely used.

The size of the pond depends on the scale of aquaculture, with a small pond of 2-3 square meters and a large pond of 20- 100 square meters. The area of family eel pond should not be too large. As far as a single swimming pool is concerned,10 ~15m2 is generally suitable. The depth of the pool water is generally 0.7 ~ 1 m, and the deeper the better.

3. The structure of eel pond includes brick pond and earth pond.

1, brick pool. Above-ground pool, underground pool or underground pool can be built. The walls of the swimming pool are made of bricks or stones. The bottom of the pool is connected with cement, which can be paved with stone, yellow sand or concrete and must be compacted. No matter the wall or the bottom of the pond, there should be no pores to avoid the tail of Monopterus albus escaping from the wall. There should be a water level difference at the bottom of the pool. Open a water outlet hole on the wall 40 cm away from the bottom of the pool and cover it with barbed wire. Plug the hole at ordinary times and use it for drainage in heavy rain. After the pond is completed, it should be washed and soaked for a few days, and then drained. The bottom of the pond should be paved with a layer of clay containing more organic matter or soil made of river mud and grass retting, and water should be poured before feeding, and the water depth is about 10 cm.

2. the earth pool. We should choose to dig a pond in a place with good irrigation and drainage conditions and hard soil, and make a ridge around the excavated soil. The ridge is 40-60 cm high and 60-80 cm wide. The ridge should be compacted in layers to prevent the eel from escaping from the soft ridge. Soil ponds are suitable for large-scale farming.

In addition, large-scale industrial eel farming was carried out, and cement ponds and gravity flow exchange ponds were built. Large sand tanks can also be used to raise eels at home.

Fourthly, simulate the ecological environment for the growth of Monopterus albus.

At the bottom of the pond, straw of about 10cm was laid first, and then disorderly bricks and right blocks with a thickness of about 20 cm were placed on the straw, thus artificially creating some caves for Monopterus albus to live in. Some aquatic plants, such as absinthe, water hyacinth, water hyacinth, etc. It can also be planted in a pond for eels to lurk, block some sunlight, improve the environment of the pond, reduce the water temperature of the pond, and be beneficial to the growth of eels.

According to Jiangsu Agricultural Science and Technology News, the prospects of Monopterus albus breeding are promising.

Monopterus albus is not only delicious in meat and rich in nutrition, but also has the effects of tonifying middle energizer, nourishing blood, treating deficiency, expelling wind and dampness, strengthening bones and muscles, etc. , with high edible and medicinal value, is deeply loved by people. At the same time, it is also one of the important export aquatic products, which can be exported to Japan, Southeast Asia and other countries, and is also very popular in Hong Kong, Macao and Taiwan, so the market price is better. For example, in the aquatic products market in Guangzhou, the wholesale price per kilogram was around 18 yuan-20 yuan from June to June last year, and reached above 23 yuan when it was high. In the middle of June last year, 65438+ 10, Nanjing sold a kilo to 30 yuan or so.
