520 $a This dissertation investigates the problem of conserving fish resources, using an approach that focused on both the social and ecological realms of fishery systems. The first and most important part of this dissertation addressed the conservation of the overexploited fish pirarucu (Arapaima ) in river floodplains of the Central Amazon. To do this, I used theories of governance of common property resources and several empirical methods including direct population censuses, fish stock assessment approaches, and computer simulation modeling.
520 $a Two studies showed that fishers are central elements of fisheries research and management schemes. I found that experienced fishers of pirarucu can assess the populations of the pirarucu (by counting the fish at the moment of aerial breathing) more accurately and cost-effectively than other stock assessment methods. I also found that integrating fishers in research and management schemes is crucial to overcoming the difficulties that commonly are associated with studying and managing fisheries in tropical river floodplains.
520 $a Three studies showed that the pirarucu are well adapted to survive the spatial and temporal heterogeneity and intense fishing pressure that are characteristic of tropical river floodplains. I found that the seasonal migrations of the pirarucu appear to optimize the use of resources that are heterogeneous spatially and temporally. I also found that the pirarucu spawn in the riparian forests, which are easily accessible to fishers. Finally, I found that annual recruitment of the pirarucu appears not to depend on interannual variations in water levels, and that their populations can sustain high levels of catch of adults if sexually immature or reproducing adults are protected from fishing.
520 $a Driven by the idea that conserving the pirarucu fishery requires integrated socio-ecological knowledge, in the end of this dissertation I assessed the adequacy of the dominant approach to fisheries management to ensure the conservation of world fisheries. I found that the dominant approach does not address the fundamental causes of fisheries degradation in the entire world and especially in the tropical developing world.
