Composite ecological breeding system

Abstract

The invention relates to a composite ecological breeding system. The composite ecological breeding system comprises four modules, namely the fish breeding module, the prawn-crab breeding module, the rice growing area and the aquatic vegetable area. A river system is established to be of a latticed structure through a culvert. By the adoption of the composite ecological breeding system, nutrients can be utilized among breeding units of different animal and plant modules, pollution is reduced, substance energy flow rate is increased, and finally zero-release, efficient and low-carbon ecological breeding is achieved.

Description

technical field [0001] The invention belongs to the intersection field of ecological breeding and ecological agriculture, and in particular relates to a compound ecological breeding system. Background technique [0002] With the depletion of wild fishery resources, it is an inevitable trend to vigorously develop aquaculture, but aquaculture must take the lead in healthy farming; healthy aquaculture mainly includes germplasm, feed, water quality, breeding models, diseases and management, etc. At the national level, a number of policies have been issued in recent years to promote it; the No. 1 document on agricultural development in 2006 is healthy farming. [0003] The premise of healthy aquaculture is good water quality. However, in today's China with comprehensive eutrophication, how to ensure a good water quality environment is the top priority; with the development of China's modernization, the trend of water eutrophication and desertification is becoming more and more se...

Problems solved by technology

Therefore, this mode can only be operated at a lower density. If the breeding density is too high, the nutrient load of the system will be too large, and the entire system will face collapse; Compound Ecological Farming in a Pond

[0006] There is another kind, such as the Fishing Machine Research Institute and the Yangtze River Research Institute, adopts the method of separate ponds and rings to establish artificial wetlands and ecological ditches for sewage treatment. There is no doubt that these wetlands and ecological ditches must have the function of purifying water quality, but in a large-scale aquaculture The area of ​​these artificial wetlands and ecological ditches must reach a certain area, otherwise it will be difficult to play the function of regulating the ecology of the pond aquaculture system

There is also a serious shortcoming in the design of sub-pool rings. If there are too many nutrients in a system, it will be difficult to support large-scale and high-density ecological breeding under serious influence; greater impact
