The fisheries in the reservoir of UHE-Tucuruí employs about 6.000 fishermen generating about of R$ 4,2 million/year1. There are three target-species: Tucunaré Cichla monoculus (caught with hook and line), Pescada Plagioscion squamosissimus (caught with gill net and/or hook and line) and Mapará Hypophthalmus marginatus (caught with gill net). Published information was reviewed and data collected during two field trips in 1999 and 2000 that included interviews with community leaders and fishermen with the following aims: to get to know the reservoir fisheries and fishermen; create scenarios of fishing effort increase; and, forecast potential conflict due to the collapse of resources. The following variables were considered: target-species landings (data records supplied by the fishermen associations), fishing gear, fishing strategies, conflicts, fishing spot allocation systems, and income. These variables, covering a period of 10 years starting from 1999, were entered into a dynamic model, simulated in the software Vensim PLE. The results indicate that the hook and line fishery is the most profitable, and potential conflicts due to resource scarcity could occur in 2005. The methodology used for the simulations and risk analyses was found to be suitable for the local reality and available data set
