Embodiment Construction

[0046] The present invention will be further described in detail below in combination with specific embodiments.

[0047] A river eel imitation wild breeding method, comprising the following measures:

[0048] A. Pond conditions and preparations: The pond area is 5 to 8 acres, the slope ratio (the ratio of the vertical height to the horizontal width of the slope) is 1.0:1.5~2.0, and the water depth is kept at 1.5~2.0 m;

[0049] Drain the pond water one month before seedlings, and manually or mechanically remove the silt, so that the bottom silt is less than 10cm. Dredging can not only increase the depth of the pond, but also help improve water quality and remove pathogens, which is the basis for successful eel breeding ;

[0050] Disinfect the clear pond 12 days before releasing the seedlings, keep the water depth at 15 cm, and use quicklime at a rate of 1500 kg / hm 2 Sprinkle the whole pond evenly, or spray the whole pond with bleaching powder at a concentration of 20-25 mg...

Abstract

The invention discloses a wild-imitation breeding method for river eel. The method comprises the following steps: A, preparing for pond conditions and other work; B, stocking seeds, wherein the seeds include river eel, penaeus monodon, chub and bighead; C, feedstuff feeding; D, daily management: (1) aerating by adopting an aerator; (2) disinfecting a water body; (3) applying a microbial preparation; (4) changing water; (5) controlling diseases: preventing, controlling and treating diseases by using Chinese Herbal medicines; E, modifying an artificial wild-imitation environment. According to the method, river eel, penaeus monodon, chub and bighead are bred in a breeding pond in a mixed way, so that the stability of a breeding system can be improved; meanwhile, the water quality environment of the pond can be improved, and the breeding benefit of unit area is increased; a marine drug prepared by compounding natural Chinese herbal medicines has the advantages of natural property, multi-functionality, small toxic and side effects and no drug resistance, the quality of marine products is improved remarkably, and the immunologic functions of aquatic animals are improved.

Description

technical field [0001] The invention relates to a river eel culture method. Background technique [0002] Because of its delicious meat, river eel is rich in protein, vitamins, minerals and essential fatty acids (DHA, EPA). The structure of its fat and protein is similar to that of the human body, so it is easily absorbed by the human body. It has become a high-end high-quality food suitable for modern consumption, and is very popular with consumers in Japan and Southeast Asia. Since river eel seedlings cannot be artificially propagated so far, the price of eel seedlings has been reduced, making the price of eel seedlings comparable to gold, becoming a veritable "soft gold", and the price of river eel seedlings has been rising all the way. [0003] In the 1980s, river eel farming started in mainland China and developed on a large scale, and the farming model is also constantly improving and developing. The early river eel culture adopted a single cement pond intensive cult...
