摘　　要：该试验进行了以草鱼为主养的池塘混养不同密度匙吻鲟试验,以池塘混养鳙鱼作为对照,匙吻鲟投放4个不同密(每塘51尾、81尾、111尾、138尾)进行试验。经过7个月的喂养,我们对养殖成本和收益进行了计算得出对照塘和试验塘投入产出比依次为1:1.16,1:1.47,1:1.25,1:1.32,1:1.27。实验结果表明:相同条件下,混养匙吻鲟的池塘收益高于混养鳙鱼的池塘,适当低密度混养匙吻鲟收益高于高密度混养。An experiment was conducted to analyse the economic benefit of mixed Culturemodel of Polyodon spathula.In the mixed Culturemodel,grass fish were cultured as main species,Polyodon spathula as an Assistant Cultured Species.A mixed culturemodel of Aristichthysnobili was conducted as comparative one.The cost and benefit of the culturemodle were be calculated after seven months.The ratios of input and output of comparative group and study groups were 1:1.16,1:1.47,1:1.25,1:1.32,1:1.27.The results showed that the benefit of mixed culturemodel of Polyodon spathula is higher that of mixed culturemodel of Aristichthysnobili.
