Aquaculture Comprehensive Benefit Evaluation

Because the aquatic product resources are limited and the strategy of sustainabledevelopment, the aquaculture industry has become the focus of industry of our country.The comprehensive benefit evaluation of aquaculture industry from the economic,social, ecological three aspects has become a research hotspot. In order to benefitevaluation of aquaculture more comprehensive, index system of comprehensiveevaluation of comprehensive benefits of aquaculture needs to be established andscreened for the theory and method of comprehensive evaluation in aquaculture.This paper will sum evaluation of comprehensive benefits of aquaculture is definedas the economic benefit, social benefit and ecological benefit evaluation. Through theliterature review of the evaluation of the aquaculture industry and other industrialeconomic benefits, social benefits and ecological benefits, aquaculture comprehensivebenefit evaluation system are established including of evaluation of economic benefit,social benefit evaluation, ecological benefit evaluation of3first grade indexes,12twolevel indexes and54three level indexes. Through the benefit evaluation method study,summarizes the theory and method of evaluation of aquaculture comprehensive benefits,such as matrix analysis method, principal component analysis, cluster analysis, greyrelational analysis, data envelopment analysis method, analytic hierarchy process, fuzzymatter element analysis method. It can evaluate a specific benefit evaluation ofaquaculture comprehensive or economic benefit, social benefit and ecological benefit inthe index and method on the basis these.At the same time, aquaculture has always been an important part of big agriculturein Shanghai. In the agricultural proportion including Penaeus Vannamei Boone farming,aquaculture gradually rise, increased from4.17%in1978to23.31%in2008, has morethan19.53%of the level of animal husbandry. In the industrial development background,the Shanghai Penaeus Vannamei Boone research has been the concern of scholars. Penaeus Vannamei Boone is one of the three highest production shrimp in the world andnative to South American Pacific coastal waters. Professor Zhang Weiquan introducedthis shrimp from USA,broke through the nursery in1992, and try to promote cultivationin all parts of the country. Shanghai in2001the introduction of breeding success. WithShanghai and even the whole country Penaeus Vannamei Boone production increasingand the proportion the total freshwater aquaculture production rising, some researchersbegan to pay attention to study the breeding technology and the breeding efficiency etc..But these are only simple analysis of the economic benefits of aquaculture frombreeding technology, breeding cost etc.. At present,in our country and even in the world,food security including aquatic products safety situation is very grim. Food safetyproblems are abnormal seriously in modern aquaculture especially intensive aquaculture.In order to ensure the safety of aquatic products, the development of aquacultureindustry needs to improve the environment, promote ecological aquaculture. Under thecondition of ensure the aquatic product safety, improve the shrimp and other aquaticproducts breeding benefit of economy and society is one of the hotspot of researchdepartment of fisheries.This paper takes Shanghai city view, based on domestic and foreign literature dataand Shanghai Penaeus Vannamei Boone breeding base for research, breeding,application of economic, ecological and economic costs and benefits, social benefits andother theories and methods, combining theoretical analysis with empirical analysis,quantitative analysis and qualitative analysis, explore Shanghai Penaeus VannameiBoone aquaculture comprehensive benefit evaluation index system. Through theanalysis of Shanghai Penaeus Vannamei Boone culture factors, comprehensive benefitand influence, make conclusions: first, Shanghai Penaeus Vannamei Boone breeding hasobvious economic benefit, Penaeus Vannamei Boone relative to other shrimp speciesbreeding profit rate is relatively high, the price and variable cost are main relativefactors. Therefore, to improve the Shanghai Penaeus Vannamei Boone farming profits,increasing Penaeus Vannamei Boone farming households income, need to start from twoaspects of raising prices and reducing variable cost. The government can protectShanghai Penaeus Vannamei Boone market price and prevent excess production causedby falling prices. In addition, can improve the farmers`level of science and technology,introduce new breeding technology, reduce the Penaeus Vannamei Boone breedingprocess cost and improve the yield. Second, Shanghai Penaeus Vannamei Boone farming has more social benefits, the effects on welfare growth and market profit areobvious, contribution to employment and industrial structure are obvious, not tooobvious to influence the spillover of technology. Thus, culture of Penaeus VannameiBoone increase farmers income and increase farmers quantity, Penaeus VannameiBoone market supply rate increases, profits and taxes increase. At the same time, alsoled to the development of social employment and aquaculture industry. Third, ShanghaiPenaeus Vannamei Boone farming ecological benefit is obvious, the effects on theconservation of natural resources and reducing the ecological pollution are obvious.Influence on the ecological contribution is slightly obviously. Thus, culture of PenaeusVannamei Boone reduced the area of arable land unit investment occuping, save naturalresources, reduce emissions and disease incidence rate. To a certain extent, reduce theenvironmental pollution and damage. Promote the development of aquacultureecological technology. At the same time, using the SWOT analysis method, ShanghaiPenaeus Vannamei Boone farming advantages, disadvantages, opportunities andchallenges are analyzed. Put forward: Shanghai should strengthen Penaeus VannameiBoone quality management, establish a sound of Penaeus Vannamei Boone in Shanghaicity of quality and safety management system, especially to grasp specification, usedrug residues, residues detection method, to ensure product quality from the source, tocope with the more and more strict product quality testing standards. At the same time,the laws and regulations are changed to follow the main importer. Take positive actionto deal with the interference of anti-dumping. In addition, to realize the industrializationof farming, increase Penaeus Vannamei Boone deep processing products, take brandstrategy, enhance the competitiveness of enterprises. Through the analysis andconclusions of this paper, provide practical guidance of Penaeus Vannamei Booneaquaculture development.
