The Relationship Between Aquaculture And Ecological Environment Of Aquatic Animals

China’s early in the records of the Shang Dynasty based friends of pond fish culture,in the Warring States period of Yue Star Fan wrote famous "pisciculture classics",creating a new model of polyculture fish and turtle,became the beginning of Chinese ancient pond integrated aquaculture.To the Tang Dynasty,began to have by the main culture of common carp and transformation is a blend of green grass carp silver carp and Bighead Carp feeding,to the end of the Ming Dynasty,green grass carp silver carp and Bighead Carp polyculture method gradually improve.In the Ming and Qing Dynasties,with the increase in the demand for fish town,trade and freshwater aquaculture gradually by the scattered keep to the road of specialization breed,feeding the fish also from the original simple polyculture to include grass,green,silver carp,bighead carp,carp,bream,carp,crucian carp,with different feeding habits and different habitat habit,and same in different age comprehensive polyculture.Gradually formed in the agriculture,fisheries and animal husbandry industry and trade combination of semi artificial compound eco agricultural system,especially in the Pearl River Delta region and the Taihu Lake region most developed,the most typical,lay a solid industrial foundation for the development of the present stage our country comprehensive ecological aquaculture.The output of aquatic products in China is the world’s first,and is the only country in the world.However,in the rapid development of aquaculture,leaving serious pollution risks.According to the Ministry of environmental protection survey,50%of the water in the river is not in accordance with the standard of fishery water quality.Local aquaculture water pollution is very serious,serious damage to the aquatic ecosystem and fishery resources,leading to increased mortality of fish and shrimp,the number of species and population decline.Farmers unreasonable river around the lake,improper damming the river,to enclose tideland for cultivation,to sacrifice the environment for the price of blind breeding and traditional breeding.At the same time,in the past twenty years,China has made a large number of pond intensive farming,put into the millions of tons of bait,fertilizer and a large number of drugs,which also led to the annual production of nearly 300000000 cubic meters of waste water discharge,more pollution and pollution level of rivers and lakes,and then lead to ecological,damage,and exacerbate the decline of fishery resources.Therefore,this research is mainly for the current situation of China’s aquaculture industry,that is,the scientific concept of development as the guide,adhere to the sustainable development and scientific and technological development,the development of ecological industry.This research has six chapters.In the introduction,the purpose,the problem,the reason,the countermeasure and the practical significance of the research and the problems to be solved in this paper are described in this paper.The first introduction of the main domestic and foreign current situation of the development of aquaculture industry and realized the problem.The second chapter introduces the main factors that affect the aquaculture and the relationship between the factors.The third chapter describes the relationship between the ecological factors and the various factors of the aquaculture.The fourth chapter introduces the main contents of the ecological and environmental system of the integrated breeding.The fifth chapter is the establishment of the ecological system including the comprehensive cultivation and the HACCP system.At the end of this paper,a brief conclusion is made and the future of ecological culture is prospected.
