Abstract :

Background and Objective: Sustainable development focuses on the continuity of resources, the stability of capital and the continuous flow of its services for the present and the future. The Sea-based economy and the optimal yeild for development are important for our country. In marine shrimp fishing, the goals are "employment, profit, participation and safety of employees, as well as the reduction of by-catch fishing and the conservation of biodiversity" are pursued. The goal is to obtain the optimal fleet according to environmental, economic and social considerations in Qeshm fishing area.Material and Methodology: Stakeholders and their objectives were identified and 70 samples were randomly selected. The weight of each goal was determined by Analytic Hierarchy Process (AHP), and the models were estimated by Linear Programming. The total allowable shrimp catch (TAC) along with the linear model estimates and its weights were analyzed through Multi-Criteria Decision Making (MCDM) and the goal programming (GP) model.Findings: In this study the preferences of the seven groups of identified stakeholders, including fisheries, labor, environmental NGOs, government, fisheries workers, researchers and processing centers, showed that maximum profit is the first priority for all groups. Reducing overfishing is the least preferred.Discussion and Conclusion: The share of the average fleet (between 20 and 50 tons) to achieve the research objectives was estimated at 64%. Based on the research findings, reducing the share of large fleet size and increasing the medium size is recommended to create harvest stability.
