吉富罗非鱼与南美白对虾混养经济效益分析

Economic benefit bnalysis on polyculture of tiapia with white leg shrimp

为探索罗非鱼高产高效养殖新模式,研究开展了2000尾/亩、3600尾/亩和6000尾/亩不同密度罗非鱼与南美白对虾混养的养殖试验,并分析该养殖模式下的经济效益。结果显示:罗非鱼6000尾/亩高密度混养南美白对虾获得较大的池塘经济效益,为较理想的投资养殖方式;高密度罗非鱼与南美白对虾混养有利于降低罗非鱼养殖病害和养殖成本,提高池塘经济效益,促进罗非鱼产业健康可持续发展。

To explore a new breeding model of high yield and high efficient of Tilapia, breeding experiments with different density of tilapia polycutturing with white leg shrimp were taken, including 2000 ind.acre-1, 3600 ind.acre-1 and 6000 ind.acre-1, and the economic benefits of different polycuturing mode were analyzed. The result showed that the highest income per pond was acquired with density of tilapia at 6000 ind.acre-1, which is an ideal culture mode. The high density of tilapia and shrimp polyculture is helpful to reduce the cost of breeding tilapia, improve economic efficiency, and promote sustainable development of tilapia industry.
