本文从经济学的观点,探讨国外水产综合养殖系统模式的生态效益和经济效益,并讨论了生物、经济等因素对水产综合养殖系统效益的影响,以及今后的研究方向。综合养殖生态效益和经济效益降低生产成本:土地、池塘的建造是池塘养鱼业的基本投资。饲料或肥料通常都是精养中最重要的支出。综合养殖系统最直接的效益,就是节省饲料或肥料。例如,我国香港地区鱼—鸭综合养殖系统,比单养鱼节省 This article discusses the ecological and economic benefits of aquaculture systems from the economic point of view and discusses the impacts of biological and economic factors on the benefits of aquaculture comprehensive aquaculture systems and their future research directions. Integrated Farming Ecological and Economic Benefits Reduce Production Costs: Land and pond construction are the basic investments in pond fish farming. Feed or fertilizer is usually the most important expense in intensive care. Integrated aquaculture system, the most direct benefit is to save feed or fertilizer. For example, China’s Hong Kong fish-ducks integrated aquaculture system, saving more than single-fish
