Shrimp deep pool greenhouse efficient ecological breeding system and method

Abstract

The invention discloses a shrimp deep pool greenhouse efficient ecological breeding system and method. The system is composed of a standard coarse pool shed with the area being 100-800 m<2> and the water depth being 0.5-1.5 m, a growing pool greenhouse with the area being 600-7,000 m<2> and the water depth being 2.0-5.0 m and a shed outside ecological purification pool with the area being 400-2,000 m<2> and the water depth being 1.5-2.5 m. Accordingly, by means of standard coarse pool shed and growing pool greenhouse temperature raising, early seedling placing, multiple stocking and multiple fishing (multiple cropping culture), harvesting delaying and growing pool depth increasing, the purposes of efficiently utilizing places for breeding, being stable in water environment and achieving astagger market of finished products are achieved, breeding waste water is input in an ecological pool to breed high-value aquatic animals or plant high-value aquatic plants so as to be purified for reutilization, and then an efficient, circulating and ecological multi trophic level shrimp breeding mode is built.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a high-efficiency ecological culture system and a culture method for shrimps in a deep pool greenhouse. Background technique [0002] With the rapid development of my country's aquaculture industry, the pond intensive culture method of "inlet channel + culture pond + drainage channel" has become the most important shrimp farming mode in my country. Due to the high stocking density and large amount of bait in the conventional intensive farming mode, a large amount of residual bait and metabolic waste accumulate in the aquaculture water body and the bottom of the pond during the aquaculture process, which can easily lead to high levels of toxic and harmful substances such as COD and ammonia nitrogen in the aquaculture environment, and water quality deterioration , so that the problem of environmental pollution has become increasingly prominent, and diseases of farmed shrimps ...

AI Technical Summary

Problems solved by technology

However, this large-scale breeding method not only needs to consume a large amount of "new water" to replenish pond water to maintain a stable water level, but also the aquaculture wastewater discharged from shrimp ponds generally contains more nutrients such as nitrogen and phosphorus, which easily leads to eutrophication in the receiving water. It has become the main source of pollution in the adjacent waters of the breeding area, and the discharge of diseased pool water is also an important reason for the outbreak and spread of the disease

It can be seen that the so-called standardized "intensive farming model" that is widely used in pursuit of production will further aggravate the situation of water shortage and frequent disease occurrence. It is a resource-consuming and unsustainable farming method.
