De-contamination clean production method for lake enclosure culture

Abstract

The invention discloses a de-contamination clean production method for lake enclosure culture. The method is characterized by comprising the following steps of adopting 50-100 mu enclosure area as a unit, setting two enclosures, wherein the area of the external layered enclosure is 50-100 mu; setting the internal layered enclosure at 10-15 meters intervals, wherein the area of the internal layered enclosure is 35-70 mu; breeding crabs, mandarin fish, freshwater shrimps, turtles, grass carps and chubs in the internal layered enclosure, planting float grass, proliferation duckweed and wild fishes in the spacing areas of the internal and external enclosures, seeding clams, snails and corbicula fluminea, and collecting and feeding to the enclosure area periodically, when eutrophication water bodies in the enclosure area pass through the spacing areas, eutrophication components such as nitrogen and phosphorus are absorbed by water plant such as the float grass and the duckweed, when organic components flow out through the water bodies, the organic components are eaten by the corbicula fluminea, the clams, the snails and the wild fishes, so that the water bodies exchanged outwards in the enclosure area are purified; and as microbial agents are used periodically to improve the water domain or water quality environment, the problem of contaminated waste water due to breeding does not exist, and moreover, the growth of breeding species are promoted and the quality of the products is obtained.

Description

technical field [0001] The invention belongs to the technical field of aquatic product production, in particular to a depollution and clean production method for net-enclosed culture in lakes. Background technique [0002] Net aquaculture is an important fishery production method. Generally, net aquaculture is carried out in lake waters. Due to the large amount of feed and feces discharged from aquatic products, a large amount of organic waste is accumulated in the net aquaculture, which causes eutrophication of the water body. Aquaculture pollution is serious, and aquaculture wastewater is exchanged with lake water quality in large quantities, affecting lake water quality. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention designs a depollution and clean production method for net culture in lakes. [0004] The technical scheme of the present invention is as follows, the decontamination and clean production method of...
