Intensive ecological efficient sturgeon culture combination pond and culture method thereof

Abstract

The invention discloses an intensive ecological efficient sturgeon culture combination pond and a culture method thereof. The sturgeon culture combination pond includes an intake canal, a sedimentation tank, a distributary tank, rectangular culture main ponds, a drainage canal, a waste water reuse pond, a subsurface wetland and the like; the intake canal is communicated with one side of the sedimentation tank, the other side of the sedimentation tank is adjacently connected with the distributary tank, the other side of the distributary tank is in transverse side-by-side connection with the twosame rectangular culture main ponds, the other sides of the two rectangular culture main ponds are adjacently connected with the drainage canal, one side of the drainage canal is communicated with the waste water reuse pond, and the other side of the waste water reuse pond is communicated with the subsurface wetland. According to the sturgeon culture combination pond, the land utilization rate ishigh, water flow exchange is complete, and a clean growth environment of sturgeons is ensured. According to the sturgeon culture method, through reusing and three-dimensional biological purificationtreatment on residual feeds and culture waste water, 'zero pollution' emission of the profitable culture waste water is ensured, not only is the income increase, but also the environment is protected,and the economic, social and ecological benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of special aquaculture, and in particular relates to an intensive ecological high-efficiency sturgeon breeding combination pool and a breeding method thereof. Background technique [0002] Sturgeon is one of the earliest vertebrates in existence. According to different regions or species, it is divided into Chinese sturgeon, white sturgeon, sturgeon, Siberian sturgeon, Russian sturgeon, Dabry's sturgeon, Atlantic sturgeon and spoon-nose sturgeon. my country is one of the countries with the most species of sturgeon, the widest distribution, and the richest resources in the world. There are 8 species of wild sturgeon in my country. Among them, the Chinese sturgeon is a rare fish that is a special product in China and is under the first-level national protection in China. animal. Sturgeons first appeared in the Early Triassic period 230 million years ago. They are as important for academic research as giant pandas. They ...

Problems solved by technology

[0004] In the existing sturgeon farming model, the residual bait and wastewater from farming are not treated but are directly discharged into the natural environment, which not only causes waste of bait, but also pollutes the environment

[0005] Through the investigation of the status quo of sturgeon farming in my country, combined with the above-mentioned data analysis, it can be known that the traditional sturgeon farming in my country has a small area of ​​a single sturgeon farming pond, shallow water in the breeding pond, and a large area of ​​the fish pond, so the land utilization rate is low; At the same time, due to the unreasonable design of traditional fish ponds, the water exchange is not complete, the dissolved oxygen in the pond water is low, and the residual bait and feces are not discharged thoroughly, resulting in serious water pollution. Moreover, the residual bait and waste water cultured by traditional farming methods are directly discharged externally, causing pollution to the ecological environment

In addition, the traditional sturgeon farming in my country still has shallow ponds, which leads to low yield and profit per unit area. At the same time, the existing methods of sturgeon farming require more manpower and material resources, and the labor cost is high, but comprehensive less effective
