摘要
Cost-benefit analysis and breakeven point were used to analyze the production cost and economic benefit of tilapia pond monoculture and polyculture.From the aspects of tilapia production and economic benefit,this paper summarized the current production status and the characteristics of tilapia industry development and analyzed its developing trend.The results indicated that feed cost,pond rates and labor cost are the main production costs,and the production cost of polyculture is significantly lower than that of monoculture.Through comparative analysis,it is proposed that the tilapia industry should be reasonably guided to the intensive,standardized and pollution-free direction.Specifically,it is necessary to improve the coverage of improved varieties,strengthen disease prevention and control and promote the healthy farming model of tilapia.We also should strengthen the training of tilapia production techniques and the quality and safety testing of tilapia products,and accelerate the development of tilapia industrialization,so as to promote the sustainable and healthy development of tilapia industry.
