| Abstract: | This experiment established a closed system of recirculating aquaculturein polyculture of shrimp and crab in pond.The preliminary ecological benefit was evaluated.The removal rate of TN,TP,NH4＋-N and CODMn was 27.33%,56.14%,43.91%and 39.59%,respectively.The total water quality index indicated that the purificated water reached the classification Ⅲ of environmental quality standard for surface water（GB3838-2002）at most cases.The net economic benefit was 53 769 yuan per hectare and the culture benefit was remarkable.The recirculating aquaculture system is a new type of revolving economic technology model. |
