Pond aquaculture water quality from the index of water quality, water color discrimination, aquaculture production in common too high or too low PH, high ammonia nitrogen and nitrite on the high side, less than a few problems, such as dissolved oxygen, sources and harm from their formation causes, and treatment measures are discussed, the hope can guide us in the process of actual production breeding using more scientific method to solve the problem of water quality, cultivating and control the quality of aquaculture water body, and reduce the risk of breeding and increase the breeding benefit. At the same time also protect our breeding water, efforts to the sustainable development of pond aquaculture development pattern.
