This paper introduces a socio-ecological analysis of the artisanal fisheries system on Easter Island (27º07′S, 109º22′W) through the identification and interaction of stakeholders. It also comprises a structural analysis of the system aiming to identify any key issues and then propose research and development programs for multiple fisheries that will contribute to their sustainable development. The methodology is divided into four stages: i) identification of issues with stakeholder (fishers, government workers and expert scientists) participation, ii) analysis of a structural matrix consisting of a direct causality study of the symmetric, structural and binary matrix based on socio-ecological issues allowing the calculation of the level of influence and dependence of each issue, iii) identification of key issues with an influence/dependency diagram, and iv) proposal of research and development programs according to the needs and opportunities identified in the previous stages. The Easter Island artisanal fishing system is used as a case study for this methodological approach. Thus, the fishers identified 108 issues, which were then grouped by similarity, reducing the number to 27 global issues, of which seven were identified as key. Surveyed local and central government workers and expert scientists identified 7, 2 and 5 issues, respectively. Finally, research and development programs are proposed that will encourage a series of changes to the fisheries situation on the island, in order to resolve issues and promote their sustainable development.
