Abstract:

The environment problem of traditional freshwater aquaculture pond was more and more serious, due to intensify the degree of eutrophication in water body around. To solve this problem, recent research emphasized on the in-situ remediation represented by “Fish-Vegetable Mutualism” Mode (FVMM) and ectopic remediation represented by Recirculating Aquaculture System (RAS). FVMM could reduce the generation and discharge coefficient of fish pond, ecological balance would be hard to realize, and RAS could not avoid the extra economic cost and land resource, the ecological value of application of this mode around eutrophication area was evident due to its zero-discharge. Establishing an ecological cooperation (EC) aquaculture model, comprised by floating-bed grown vegetables in water upper, and constructed wetland receiving waste water of fishpond, would be an effective way to solve the problem caused by traditional freshwater aquaculture. Cooperation society was an effective platform to reflect the technologies of aquaculture, aquaculture cooperation society was characterized by “economic cooperation”, followed by “information cooperation”, “ecological cooperation” would be a tendency.
