摘　　要：使用2口面积2000m2的池塘养鳖,在池塘中种植水葫芦并搭养鲢鱼,以期净化、改善养殖水质。使用2口面积相同的池塘作为对照。对比养殖试验进行了4个月,期间每隔10d测定COD、NH3-N、NO2-N、DO、悬浮物(SS)等水质指标,并观察鳖的摄食和疾病情况。结果表明,在养鳖池中种植水葫芦和搭养少量鲢鱼,有利于改善水质减少鳖病的发生,降低渔药的使用。In order to improve the water quality,Eichhornia crassipes solms was planted and Aristichthys nobilis was reared in two Trionyx sinensis cultured ponds with an area of 2000 square meters.Another two ponds with the same size were used as control in which only Trionyx sinensis was bred for four months.During the experimental,the water quality index including COD,NH3-N,NO2-N,DO and suspended substance were analyzed every 10 days.The ingestion and diseases of Trionyx sinensis were written down.The results showed that the water quality of the experimental ponds could be improved,either the occurrence of diseases of Trionyx sinensis or the using dosages of fishing medicine could be decreased by planting of Eichhornia crassipes solms and breeding of Aristichthys nobilis in the two experimental ponds.
