Net cage culture technique of Loach for high yield and easy fishing management

The cultivation of Loach in cage has the advantages of simple equipment, high yield per unit area, convenient management, easy fishing and remarkable economic benefits. it is a culture technique worth popularizing. The main technical points of cage culture of Loach are introduced as follows:

Misgurnus anguillicaudatus cage culture

1. Site selection: Misgurnus anguillicaudatus culture site should be selected in the lake, shallow water near the reservoir and living water pond, with good water quality and no industrial pollution.

Second, cage setting: cage specifications can be large or small, small area 1-2m2, large 20---40m2, generally 10--20m2 is appropriate. The box made of polyethylene woven mesh, mesh 0.5-1.0cm, net height depends on the aquaculture water body, but the upper half of the cage must be higher than 40cm above the water surface to prevent Loach escape, the bottom of the box should be covered with thick 20cm manure and soil, and the top layer is soil. When transplanting aquatic plants in the box, it is better to use water-bearing plants (such as water peanuts). The amount of aquatic plants accounts for about 1 / 2 of the area of the cage.

3. Loach species stocking: the stocking amount of Loach species in the cage depends on the water body conditions, water, fertilizer and water work can be released more, otherwise less. Generally, the Loach species of 900 Mel 1200 tail 5-6cm are released per square meter.

4. Feeding and management: Loach is cultured in cage, mainly by artificial feeding. A food table of about 2m2 should be set up in the cage, which is 20-25cm from the bottom of the pool. When feeding, put the bait on the table. Artificial bait can be fed with synthetic pellet feed or full-price pellet feed. Animal protein accounts for more than 50% of the full price feed. The daily feeding amount is 3% Murray 5% of the body weight of Loach, which is fed three times in the morning, in the middle and in the evening.

Fifth, daily management: net clothes should be scrubbed frequently, keep water permeability inside and outside the cage, and can make enough bait creatures into the box, at the same time, always check the net clothes, if there are loopholes, fix them immediately. In addition, it is also necessary to prevent pollution such as pesticides and chemical fertilizers and attacks by natural enemies.

Sixth, disease prevention: usually do a good job in the prevention and control of Loach disease. When taking bait, we should adhere to the "four fixed" principle, remove the residual bait on the table in time, sprinkle quicklime or hang bags with bleach regularly, and take Duohe Changyanling internally. Bleach hanging bag method: wrap bleach with two layers of gauze and hang 3 bags around the table at a time, which can effectively prevent the occurrence of diseases.
