The UHE Coaracy Nunes reservoir, in the State of Amapá, Brazil is the oldest of the Amazon and was built with the purpose of producing electricity. This study aimed to investigate the fishing reservoir Coaracy Nunes and vicinity, describing fish production, fish species of greatest interest and socio-economic aspects of fishing. The methodology used was based on inquiries directly to 53 fishermen using specific forms containing questions on socio-economic aspects of fishing and over fishing. Results showed that fishing in the study area is a subsistence activity, but with trends artisanal fishing. The main fishing gear used is gillnets, followed by spear and harpoon and hook underwater. The composition of the fish community was composed of 13 fish species, especially in terms of biomass for Cichla sp. Hoplias macrophthalmus, Tometes trilobatus and Leporinus sp., which together comprised 47.55% of the total fishing. Fish production was low compared to other reservoirs latest. Resident fishermen for over 50 years in the region claim that in the pre-bus the river existed remarkable abundance of large species, which suggests that the bus from the river and fishing were the main factors in the elimination and reduction of stocks of some species in the reservoir area main factors in the elimination and reduction of stocks of some species in the reservoir area.Keywords: Araguari; subsistence fishing; fish production; fish stocks.
