Embodiment Construction

[0040] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0041] As shown in Figure 1, a kind of recirculating water aquaculture system based on microalgae comprises the first cultivation subsystem of culturing the first aquatic product and the second cultivation subsystem of the second aquatic product cultivation, the first cultivation subsystem It is connected with the second breeding subsystem through pipelines to perform breeding water circulation. The first aquaculture subsystem breeds the main aquatic products that people eat, such as fish and shrimp, but during the aquaculture process, the excrement and residual bait of aquatic products will decompose in the water to form nitrogen and phosphorus pollutants, thus affecting to the water quality of aquaculture water bodies. Therefore, the present ...

Abstract

The invention provides a aquaculture system which uses light energy to realize cycle of water with a media of micro-algae and inhibits the disease occurrence of aquaculture species. The system includes two aquaculture subsystems which are connected through pipes for water cycle of aquaculture. The water-recycled aquaculture system based on micro-algae forms biological cycle chain through reasonable combination of the two aquaculture subsystems to significantly improve the efficiency of aquaculture. The circulating water based on micro-algae transfers surplus nutrient in aquaculture of the first aquatic product to the second aquatic product, and to be used as bait of the second aquatic product. Therefore, the water consumption is reduced and the discharged 'waste' is changed to effective nutrient. The bacteriosis occurrence of aquatic products is inhibited by using natural antibiotics secreted by micro-algae, and in addition, the infection probability of virus diseased is reduced.

Description

technical field [0001] The invention relates to an aquaculture system, in particular to an aquaculture system which utilizes light energy and uses microalgae as a medium to recycle water resources. Background technique [0002] At present, the aquaculture industry has encountered two major problems, one is water resources and environmental pollution caused by aquaculture, and the other is the problem of aquatic product diseases. These two problems are closely linked together, the pollution of the water environment will lead to the growth of harmful bacteria, resulting in frequent occurrence of diseases. While the traditional breeding technology has greatly increased the area output, it also brings potential crises. The main manifestation is that farming is not only a victim of environmental pollution, but also one of the sources of environmental pollution. The pollutants caused by fish, shrimp, crab and shellfish farming include Residual bait, chemical fertilizers, disinfec...
