Practice And Benefit Evaluation Of Pond Standardization Improvement In Fish Farm Of Yongxing,Hunan Province

In this paper,the breeding field of fish and spawning fish breeding in Yongxing County for more than 50 years has been studied as a research object.The changes of before and after the pond standardized breeding in the breeding fish farm of Yongxing County have been comparatively analyzed.From the aspects of economic benefit,social benefit and ecology Benefit from the three aspects of the old fisheries pond standardized implementation of the effect.The purpose is to compare the situation before and after the standardization of the pond by the old fishing grounds and reflect the obvious effect after the reconstruction.The purpose is to analyze the necessity and promotion of standardized pond rebuilding in the old fishing grounds.Standardized after modification,the results show that the implementation of the pond fish reproduction number is 1.5 times before modification,and fry fish stocking density is 4.5 times of before modification,and output quadrupled,the ratio is 1:1.12-1.18 to 1 to 1.45,profits from 5-140000 yuan before modification jumped to more than 80 ten thousand yuan.At the same time,after the standardization of the pond,the fishery facilities are improved and the environment is beautiful,which creates conditions for the development of leisure fishery,and it won a number of "demonstration field" title,to a certain extent,improve the reputation of fish and seed breeding farms in Yongxing County industry,but also on the standardization of pond construction technology has played a good role in promoting the promotion.Therefore,the implementation of standardization of ponds will play a crucial role in the future development of fisheries.
