A set of freshwater fisheries management institutions in the central Brazilian Amazon leads us to propose an expansion of the common pool resource (CPR) management models developed by Ostrom. We analyze the origins and effectiveness of a community-based CPR system that has emerged despite several features that are, in Ostrom’s view, barriers to local institutional development: the fish populations are migratory rather than stationary, spatial boundaries are ambiguous rather than fixed, and state support of local management is weak or non-existent rather than strong. We argue that cultural and political factors, which are given less emphasis in Ostrom’s model, may help explain how these communities overcome barriers to collective action. We draw parallels between freshwater systems and Marine Protected Areas and discuss implications for local resource management.
