摘  要:
在河蟹青虾混养池塘构建封闭式循环水养殖系统,并对其净化效果和养殖效益进行了初步研究。结果表明:该系统对水体TN、TP、NH4+-N和CODMn的平均净化效率分别为27.33%、56.14%、43.91%和39.59%。经湿地净化后的水质能够达到GB3838-2002地表水Ⅲ类排放标准,平均纯收益达53769元/hm2。

摘  要:
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.
