Attention should be paid to the technology of raising Monopterus Albus in science and ecology.

Ecological culture of ricefield eel can not only solve the problems of water quality control and bait supply, but also has the advantages of low cost, simple method and high benefit.

The construction of yellow eel pond. According to the general method of building the pool, the area of the pool is 3050 square meters, and the wall of the pool is 0.8 to 1.0 meters high. the water inlet and outlet is set at the opposite corner, and anti-escape facilities are installed.

Make up the dirt beds. Pile several soil beds 1 to 1.5 meters wide and 20 to 25 centimeters high in the pond (soil rich in organic matter is selected) to breed earthworms and drill holes in ricefield eels.

Raise earthworms. After the earth beds are piled up, keep the water in the ditch at a depth of 5 to 10 centimeters. Put 2.5 kilograms of earthworms in Daping No.2 per square meter of soil border, and spread fermented livestock manure 4cm thick on the border as bait for earthworms. After that, the upper livestock dung was shoveled away every 3-4 days, and a new layer was laid, so repeatedly, after about 14 days, a large number of earthworms were multiplied, and the eel species could be put in. The cultivation of earthworms can provide most of the bait for Monopterus Albus in spring, summer and autumn.

Stocking density. The size of eel species in eel pond per square meter is 50 eels per kilogram, the survival rate is more than 90%, and the weight of each tail is more than 100 grams when leaving the pond.

Mixed field snails. On the 4th day after the eel was planted in the pond, 10 kg of field snails were put into the eel pond per square meter. In addition, we should also raise some water lotus or duckweed on the surface of the water. The main purpose of raising field snail is to solve the feed problem of Monopterus Albus in early spring; water lotus and duckweed can carry out photosynthesis, increase the dissolved oxygen in eel pond and improve water quality.

Feed control. When the bait is obviously insufficient, it is necessary to supplement the feed, which can be fed with mixed feed. When there is a surplus of bait, the bait should be salvaged out of the pool in time.

Raise the snails. Field snails feed on microorganisms, diatoms and fish residual baits in the soil, and Monopterus Albus can swallow larger field snails when they grow up. Therefore, species snails should be supplemented according to the feed conditions.

Water depth control. Keep the water depth at about 10 cm, and there should be micro-running water all the time. At the same time, do a good job in daily management work, such as prevention of escape, disease and enemy damage.
