罗氏沼虾(以下简称虾)是淡水虾中个体最大的一种。它生长快、食性广、抗病力强,且肉质鲜美,营养丰富,是一种名贵水产品。1976年引入广东、广西试养,现已成功地推广到全国20多个省、市养殖,在四川、江苏、上海、山东等地区已成为出口创汇的拳头产品。虾与鱼池塘混养,以虾为主,搭配适当鱼,既可充分利用水体,全面发挥池塘生产潜力,又可净化水质促进虾的生长。生产实践证明,虾、鱼池塘混养,一般亩产虾65～100公斤、鱼100～150公斤,投入产出比1∶2.2～3,经济效益十分显著。现将虾与鱼池塘混养高产技术介绍如下: Macrobrachium rosenbergii (hereinafter referred to as shrimp) is one of the largest freshwater prawn individuals. It grows fast, fast food, resistance to disease, and the meat is delicious, nutritious, is a valuable aquatic products. Introduced to Guangdong and Guangxi in 1976, it has been successfully popularized to more than 20 provinces and municipalities in China. It has become a leading product of foreign exchange earning in Sichuan, Jiangsu, Shanghai and Shandong. Shrimp and fish pond polyculture, shrimp-based, with the appropriate fish, either full use of water, the full potential of the pond production, but also purify the water to promote the growth of shrimp. Production practice shows that shrimp and fish polyculture ponds, general mu shrimp 65 ~ 100 kg, fish 100 ~ 150 kg, input-output ratio of 1: 2.2 ~ 3, the economic benefits are significant. Now shrimp and fish pond polyculture high yield technology is as follows:
