Technical points of artificial Culture of Monopterus Albus with simple cost and low benefit

Ricefield eel, also known as eel, long fish, its tender meat, delicious taste, less bone spurs, rich in protein, a variety of vitamins, minerals. Monopterus Albus has strong adaptability, tolerance to hypoxia and hunger, and easy to transport. it has the advantages of simple culture method, low cost and high economic benefit, so it is suitable for small-scale culture.

Monopterus Albus culture

1. Construction of eel ponds:

Monopterus Albus breeding pond should be built in shelter from the wind and the sun, near the water source, and the area should be adjusted to local conditions, generally 50 Mel 100 square meters. The pool is 1.5 meters deep and is rectangular, square and oval in shape. it can be built with cement, stone, bricks, concrete and other materials, and finally sewn with cement, or hard soil, but the perimeter and bottom of the pool must be covered with linoleum. In order to prevent Monopterus Albus from escaping, the top of the pool wall should be made of bricks into a "T" shape, the top of the pool ridge should be higher than 30cm above the water surface, and the inlet and drain pipes and overflow pipes should be firmly sealed with barbed wire to strictly prevent the escape of Monopterus Albus.

After cleaning and disinfecting the rice eel pond, lay stones, bricks or tree roots at the bottom, and then layer 30cm thick, soft and hard, containing organic river mud or loam retted with grass and cow dung to create a comfortable artificial nest for Monopterus Albus. Then add fresh water to make the water deeper than 5-15cm. Finally, planting aquatic plants on the pond surface, such as Zizania caduciflora, Zizania latifolia, Pleurotus ostreatus, etc., can not only shade the rice field eel, but also reduce the water temperature, which is beneficial to the growth of rice field eel.

Second, seedling selection and stocking:

1. Be sure to choose eels with strong physique, no injury, lively swimming, neat specifications, thick muscles, free of parasites and bright yellow body color. Ricefield eel with white surface, broken skin, broken tail, scars on mouth and Gill bone should not be stocked.

2. Stocking: after disinfection and water injection in the yellow eel pond, eel species can be put in when the water temperature is above 15 ℃. Before stocking, eel seeds should be soaked in 10ppm bleach or 3mur45 salt water for 20 minutes to kill their body surface pathogens. For eel species with 40 eels per kilogram, the stocking density is 150 eels per square meter. Mixed culture of 10 Loaches per square meter, let them move up and down to improve the water environment.

3. Feeding and management:

1, qualified feeding: Monopterus Albus: mainly meat, especially like to eat fresh feed, can also be fed with some plant feed, Monopterus Albus into the pool, must immediately be raised and domesticated, so that it can eat a variety of formula feed, and can eat at 9 am, 4 am or so. Ricefield eel feeds vigorously at 25 Mel and 30 ℃, so it is the peak feeding period from May to September. The general feeding amount is 3% of the fish's body weight. In the peak growing season from June to August, the feeding amount can be increased to 6%, feeding twice a day. To achieve regular, quantitative, fixed-point feeding.

2. Water level control; the water level must be controlled at 5-15cm for a long time and cannot exceed 20cm, so that it is convenient for Monopterus Albus to put its head out of the water to breathe air.

3. Water quality regulation: water can be changed once every 8 days in spring and autumn, and once every 3 days in summer. At the same time, remove the residual bait and sundries in the pool every day to keep the water quality fresh all the time.

4. Overwintering management: when the water temperature dropped below 15 ℃, Monopterus Albus began to drill into the depths of the soil to survive the winter until February of the following year. During the overwintering period, the pool should be drained and covered with straw or wheat straw to keep the soil moist and the soil layer humid.

In short, in the process of raising eels, in addition to strengthening feeding and strictly controlling the water level and water quality, we should also check the block frequently, especially in the flood season, and do a good job in preventing escape. In addition, it is also necessary to prevent pesticide pollution and harm to water rats, snakes, cats and so on.
