Analysis of the main influencing factors of sustainable devel-opment of recreational fishery in Zhejiang Province based on questionnaire survey

Recreational fisheries play a vital role in promoting sustainable coastal development, yet empirical research to inform policymaking remains limited. This study investigates the factors influencing the sustainable development of recreational fisheries in Xiangshan County, Zhejiang Province, using principal component analysis of questionnaire survey data. The analysis identifies five key dimensions: resources, infrastructure, service quality, fishery culture, and recreational fishery activities. Results indicate that infrastructure and the natural environment exert the strongest influence on sustainability outcomes. Based on these findings, policy recommendations are proposed to enhance both ecological and economic value. First, government planning should prioritize infrastructure improvements to enhance tourists’ convenience and comfort. Second, cultural aspects of fishing should be further developed through local activities that enrich cultural heritage and improve the attractiveness of recreational fisheries. Third, production safety must remain a fundamental priority to ensure long-term industry stability. Overall, the study emphasizes the need to create distinctive recreational fishery products, improve service quality, strengthen ecological protection, and advance resource management. The proposed “environment + industry + culture” framework offers a practical evaluation tool for policymakers and stakeholders. By integrating ecological, cultural, and economic considerations, recreational fisheries in Xiangshan County can achieve green and sustainable development while meeting the evolving needs of tourists.
