南美白对虾与草鱼、鲤鱼混养技术

为了有效预防南美白对虾疾病的发生,提高池塘养殖综合效益,将南美白对虾与草鱼、鲤鱼混养进行养殖试验,结果每公顷平均产虾3 600 kg、草鱼3 300 kg、鲤鱼2 400 kg,每公顷产值11.67万元,每公顷成本7.59万元,每公顷利润4.08万元。养殖实践发现,该种混养模式有效利用了水体空间,增强了水体的自净能力;有效阻断病害的传播途径,避免了虾病的暴发;降低了养殖风险,提高经济效益。

Technique for Polyculture of Litopenaeus vannamei,Ctenopharyngodon ideUus and Cyprinus carpio

In order to effectively prevent the occurrence of diseases of Litopenaeus vannamei and to increase the comprehensive benefit of pond culture, the technique for polycuhure of Litopenaeus vannamei, Ctenopharyngodon idellus and Cyprinus carpio was developed. The output production of Litopenaeus vannamei, Ctenopharyngodon idellus and Cyprinus cazpio under the polyculture condition was 3 600, 3 300 and 2 400 kg, respectively. The production value was 116,700 Yuan per hectare, and the net profit was 40,800 Yuan per hectare. The mode of polycuhure of different aquatic animals was effective for the utilization of water space; The ability of self-cleaning of the water in pond was enhanced; The transmission route of aquatic animals diseases was effectively blocked, avoiding the outbreak of the diseases. The risk of the aquaculture was reduced and the economic benefit was increased.
