Evaluation Of Technical And Economic Benefits Of Eel Cage Culture

In recent years, with the continuous improvement of living standard, people tend to consume more and more expensive special aquatic products.For its higher food value,domestic and foreign consumers are favor to eel. The great demand of consumer market promote our country's eel farming industry developed rapidly. More and more farmers started in eel farming,as the first province of aquaculture,the Hubei province make use of its superior resources of fresh water to explore the cage culture model, and achieved good economic results.However,as the scale and production of eel cage culture rising,eel culture exposed more and more problems,such as over-fishing of wilds eels,artificial breeding of seed technology lag, lack of effective disease prevention eel, eels and feed efficiency, etc. These factors behind the development of eel farmers led to increasing input costs, access to Income instability, facing the risk of increasing aquaculture production.In order to promote the eel aquaculture industry to developed healthyly and sustainedly,from an economic point of view of economic cost-benefit to compare and analyze the main factors becomes increasingly important.The first chapter is the introduction, we introduces the research background and significance,and then conculde the domestic and foreign scholars'research and introduces the research methods and technical line and likely innovation and defection.The second chapter describes the data sources and statistical description, including Xiantao, Hannan, Honghu three survey areas of basic farming conditions, and the sample data collection process.Then we statisticed and descriped the age structure of farmers, education, farming experience and level of farmers'scale.The third chapter mainly compared and analyzed the cost of cage culture of eel.First, from the cost level and cost structure of the aquaculture projects compared three regions.Then, by constructing a model of the natural logarithm, the author analyzed cost differences between different regions. Analysis showed that different regions of the main factors affect the cost of breeding costs are basically the same, which is seeding cost, fresh feed costs and feed costs. The same factors influence the cost of a slightly different in different regions.The forth chapter mainly analyzed the cost-benefit and differences factors of the eel cage culture.First of all farmers in the same region to compare the level of costs and benefits and found that Xiantao area farmers the highest level of profit, Hannan followed, and finally Honghu. And through analysis of variance to compared between different areas the level of costs and benefits of farmers.Found three regions have obvious differences in profit levels. Then from the output, price, weight gain cost, feed conversion and other aspects of the farmers of the economic benefits of the three regions with relatively wide. Finally, the production function model analyzes the differences between different regions of eel production factors, Analysis showed that seed input, feed inputs, labor and employment, and other material inputs on the eel yield a more significant effect.The fifth chapter analyzed the main factors that affect the cost-benefit of eel cage culture. The research object is the famers'eventual profits,through establishing regression model to analze the main factors of economic profit.The regression results shows that farmers farmers experience in breeding, feed utilization, the price level and the breeding base level of infrastructure improvement on the profits of farmers have a more significant impact. Therefore, take active measures from these factors can significantly increase farmers profits.The sixth chapter is based on the foregoing analysis summarized the major points of conclusion, and on this basis, propose appropriate policy recommendations to provide a reference to promoto the eel cage culture.
