Acrossocheilus fasciatus breeding method based on breeding pond and paddy field tail water purification system

Abstract

The invention relates to an acrossocheilus fasciatus breeding method based on a breeding pond and a paddy field tail water purification and utilization system. The system comprises the breeding pond and a paddy field, wherein a fish stopping net is arranged in the breeding pond, the area of the paddy field is more than 80 times the area of the breeding pond, a sedimentation pond is arranged in thepaddy field, and the area of the sedimentation pond is 1.5-2 times the area of the breeding pond; and shrimp ditches are also arranged in the paddy field and are used for breeding silver carp, bighead carp, plagiognathops microlepis and crayfish in the paddy field. The acrossocheilus fasciatus is bred in a breeding pond on the upper part of the fish stopping net, residual baits and fish manure sink into the bottom of the pond through the fish stopping net and enter the sedimentation pond along with water flow, and large-particle substances in the residual baits and the fish manure are precipitated in the sedimentation pond, and are convenient to collect for farmland use; small granular materials enter the paddy field and the shrimp ditches along with the water flow, and can be eaten by the plagiognathops microlepis and the crayfish; and nitrogen and phosphorus which are easily dissolved in the water body can be absorbed by growth of rice and waterweeds, so that breeding tail water isfully purified. On the one hand, the invention provides the acrossocheilus fasciatus breeding method, and on the other hand, the standard discharge of the bred tail water can be ensured.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a system and a cultivation method for the cultivation of light-lipped fish and the purification and utilization of tail water. Background technique [0002] The light-lipped fish is a small freshwater economic fish that inhabits mountain streams. It is distributed in Zhejiang, Anhui, Fujian and other places. It is widely distributed in the mountainous areas of southern Anhui. It is called "grouper" because of its black horizontal spots. The light-lipped fish is tender and nutritious. It has a broad consumer market in Anhui, Zhejiang, Jiangsu, Shanghai and other places, and the price is as high as 80-120 yuan / kg. However, the culture of light lip fish has strict requirements on dissolved oxygen, water temperature and transparency of water body. At present, the breeding of smooth lip fish is mainly to build breeding facilities on both sides of mountain streams and...

AI Technical Summary

Problems solved by technology

At present, the breeding of smooth lip fish is mainly to build breeding facilities on both sides of mountain streams and drain mountain spring water for breeding. Because it is running water farming, the tail water carrying residual bait and feces is continuously discharged from the breeding pond, or through simple sedimentation. , or directly discharged into river ditches without treatment, which can easily cause water environmental pollution

However, the existing light-lipped fish farming technology does not pay attention to the separation and collection of fish-feces, nor does it pay attention to the development of tail water purification and reuse technology.
