Relay Breeding Mode Build

Currently, the world population has always been far more than70million. Resourcesbrought by rapid population growth, energy, food shortage has become the constraints ofthe outstanding problems of the social and economic development of coastal countries andregions. March to the sea, to ask for food to become a strategic focus on the developmentof the countries and regions of the coastal to the ocean. China is the world’s largestfisheries production, and the development of the fisheries is China’s basic national policy.Zhejiang is one of China’s major fisheries provinces, more than a decade, the large yellowcroaker industry has made brilliant achievements. Also, there have been a lot ofdevelopment issues, such as germplasm degradation, poor breeding environment, commonproblems of the farming enterprise efficiency and low mariculture industry.This paper introduces the concept of breeding mode, using a combination of empiricalanalysis and normative analysis, qualitative analysis and quantitative analysis of thecombination, the combination of statistical analysis and comparative analysis, staticanalysis and dynamic analysis of a combination of analytical methods and research ideasfrom change optimize the angle of farming methods, and proposed Relay farming modelbuilding. Based on the discovery of large yellow croaker in Zhejiang industry status quo,large yellow croaker Relay breeding mode build, and relay the mechanism of action of thefarming model described, exploring the new direction of the aquaculture industrydevelopment in Zhejiang large yellow croaker On this basis, the next step in the researchprogram.The entire article is divided into five chapters, the first chapter introduces buildingRelay farming model in the context of population growth, per capita shortage of resources,the development of marine fisheries, explore a new way out of the large yellow croakerindustry in Zhejiang, expand; Chapter II conditions highlights the connotation of the relaybreeding patterns, the need to build, build and build steps; Chapter introduces large yellowcroaker industry development in Zhejiang, a brief review of the history of its development,in the description of the development status of the large yellow croaker breeding industry,pointed out that the main problem restricting the development; fourth chapter focuses onnew strategies to solve large yellow croaker industry in Zhejiang Province to build thebreeding patterns of large yellow croaker Relay, enhance the large yellow croaker farmingand the introduction of the transfer characteristics HAPPC system and the use of relaymode industries. Chapter summary of the entire article, and raised expectations relay breeding patterns of other aquaculture species.
