Research On Cost And Benefit Of Trawl Fisheries And Its Impact On Fishermen's Willingness To Protect Fishery Resources

As a special group of fishermen who "rely on the mountains and drink on the water," marine fishing is the guarantee of their lives.As one of the main methods of fishing,trawling is mainly carried out in continental shelf waters,and its catch accounts for about 40% of the world's total marine catch,which is the main source of aquatic products.However,with the continuous deterioration of the marine environment,fishery resources have gradually declined,creating a situation of "more ships and less fish".At present,there are two prominent contradictions in the development of fishery:one is the contradiction between the protection of marine ecological environment and the development of regional economy;the other is the contradiction between the protection of fishery resources and the improvement of fishermen's livelihood.Against the background of the shrinking marine fishery resources,the State Administration of Agriculture and Rural Affairs has issued a series of fishery resource protection and management policies such as “catch quota,“seasonal fishing” and “dual-control”systems.The Fishermen's profits will be influenced.Therefore,it is necessary to analyze the costs and benefits of trawl fisheries and explore their impact on the fishermen's willingness to protect fishery resources.This directly affects the protection of fishery resources and the future development of the fishery industry.It also has important guiding significance in ensuring the production and life of fishermen.This article is divided into six chapters for analysis and elaboration.The first chapter is the introduction.Firstly,it elaborates the background and significance of the research and the feasibility of the research.Secondly,it constructs the technical roadmap of the article from the research content and structure framework.Finally,it introduces and combs the main research methods used in the research and puts forward the possible innovations and shortcomings of the research combined with the actualsituation.The second chapter mainly introduces the related concept theory and literature review.First,combined with the research issues,the relevant theories related to cost-benefit and willingness to protect fishery resources are reviewed.Second,the influencing factors and analysis methods on cost-benefit and willingness to protect the ecology.The relevant research literature was combed,and the literature was objectively reviewed.The third chapter is the current status and development dilemma of trawl fisheries.First,it analyzes the current status of trawlers in the country as a whole,and then analyzes the status of trawlers in Rongcheng,Xiangshan,and Beihai from a micro perspective.The fourth chapter is the comparative analysis of the cost-benefit of trawling fishery.Combined with the field survey of trawlers in Rongcheng,Xiangshan and Beihai in 2018,on the basis of 80 valid questionnaires,through the combination of qualitative analysis and quantitative analysis,on the basis of field survey,based on the cost-benefit theory,this paper uses the break even method and sensitive method Sex analysis method,compare the cost-benefit situation of three places.The fifth chapter is an empirical analysis of fishermen's willingness to protect marine fishery resources and its influencing factors.The author investigates the fishermen's willingness to protect fishery resources in Beihai,and obtains 40 valid questionnaires.Then,based on the theory of planned behavior,combined with the quota fishing policy,through the establishment of logistic model,the author analyzes the influencing factors of fishermen's willingness to protect fishery resources,and finally makes the empirical conclusion.The results are basically the same as the previous research hypothesis.The sixth chapter is the conclusion and suggestions combined with the actual problems.This part is mainly a summary of the article,which is divided into the main conclusions and relevant policy recommendations.The important conclusions of this study are:(1)The employees in Rongcheng,Xiangshan,and Beihai have problems such as being older and less educated.(2)In terms of cost and benefit composition,the largest proportion of the total cost of trawler fishing in the three sea areas is oil,ice and water expenditure,followed by labor costs;the proportion of fishing production income to the total revenue is about 90%;from the comparative analysis of the fishing income of trawlers in the sea area,it can be found that the highest profit is the trawler in Xiangshan and then Rongcheng,and the trawler in Beihai has the lowest profit.In general,high investment and low profit are the current production status of the trawler marine fishing industry in China.(3)In the case of fuelsubsidies,the three sea areas is in a profitable state;without fuel subsidies,Rongcheng and Beihai are losing money.(4)Of the three sea areas,the most affected by the market volatility is the Beihai region,which is the most difficult to resist the impact of market risks.(5)As far as the fishermen's willingness to protect marine fishery resources is concerned,the cultural level of the fishermen,the number of family laborers,and the number of years of employment have a positive effect on the fishermen's quota fishing;the age of the fishermen,the purchase price of the ship,and the net profit of fishing have a negative effect on the willingness of fishermen to limit fishing;social security has no significant effect on the willingness of fishermen to limit fishing.Based on the above research,the policy suggestions given in this article are:(1)On industrial structure level: encourage fishermen to switch their production and industry;accelerate the adjustment of the fishery industry structure.(2)On technical level:strengthen fishing technology training;upgrade and upgrade fishing equipment.(3)On policy level: improve subsidy policies;establish and improve fishermen's social security system.(4)On sustainable development level: carry out publicity and education on the protection of fishery resources;strengthen fishery management and improve relevant laws and regulations.
