摘　　要：为了鱼菜共生养殖模式的进一步推广与广泛应用,降低传统养鱼模式对环境造成的影响,进行了鱼菜共生模式与传统养殖模式的比较研究。通过测定增重率、特定生长率、成活率、肠蛋白酶活力、肠脂肪酶活力和肠淀粉酶活力等指标,研究鱼菜共生养殖模式对锦鲤生长、消化酶活力的影响。结果表明,不同空心菜生物浮床覆盖面积(5%、10%、20%、40%)对锦鲤增重率、特定生长率、肠蛋白酶活力、肠脂肪酶活力和肠淀粉酶活力等均有促进作用。10%的空心菜生物浮床覆盖面积可有效加快锦鲤的生长速度,并对其消化酶活力具有显著促进作用,适合进行中试。从经济效益各项指标来看,该模式在经济效益计算5 a期内,已获经济效益为1 056.14万元,预测未来产生的经济效益为1 859.64万元,可实现年经济效益583.22万元,应用该模式平均1元研制费用,在模式应用于养殖生产后平均每年将为社会新增加纯收益4.17元,经济效益显著。In order to further promote and widely apply the aquaponics mode,thereby reducing the environmental impact of traditional fish farming mode,a comparative study of aquaponics mode and traditional culture mode was carried out.The effects of aquaponics culture mode on growth and digestive enzyme activity of Cyprinus carpio haematopterus were studied by measuring the weight gain rate,specific growth rate,survival rate,intestinal protease activity,intestinal lipase activity and intestinal amylase activity.The results showed that different coverage of biological floating bed of Ipomoea aquatica Forsk(5%,10%,20%,40%)had a promoting effect on the weight gain rate,specific growth rate,intestinal protease activity,intestinal lipase activity and intestinal amylase activity of C.carpio haematopterus.10%of the coverage area of the biological floating bed of Ipomoea aquatica Forsk could effectively improve the growth of C.carpio haematopterus,and significantly promote its digestive enzyme activity,which was suitable for pilot test.Judging from the indicators of economic benefits,the mode had obtained economic benefits of 10.561 4 million Yuan in the five-year economic efficiency calculation period,and the economic benefits that might be generated was 18.596 4 million Yuan,and the annual economic benefit reached 5.832 2 million Yuan.After the mode was applied to aquaculture production,each unit of development funds could increase the net income by 4.17 times,and the economic benefits was significant.
