The sustainable management should be the principal objective of any proposal to regulate and to use natural resources. Based on concepts of ecodevelopment and viable development, the present research evaluated sustainability of mangrove crab fishing, Ucides cordatus, in municipality of Cananéia, at south of the State of São Paulo, Brazil; and its management possibilities. Procedures were open interviews, semi-structured interviewing, directly observing, informal colloquies and followed trips. Production and measures of crabs captured by traditional technique completed the research data. Results evaluation included as qualitative analysis (property rights and management practices) as well quantitative analysis (RAPFISH method). The history shows this fishing activity as secular and for subsistence, inserted in market during the 70 decade, and now a days adopting two conflicting methods: arming and small net . There is a large local knowledge about abiotics, biotics and supernatural aspects concerning mangrove crab fishing; but the approach is different between arming and small net fishermen. The results shows that to reach the sustainability it is necessary to manage the resource focusing social and economics aspects, creating or fortifying the local institutions, and proposing feedback mechanisms; to have a more dynamic and more effective regulation for the mangrove crab fishing.
