FALL OF PRODUCTIVITY OF FISH IN RIO TOCANTINS: PERCEPTIONS OF FISHERMEN MARABÁ – PARA

Abstract

ABSTRACT: The combination between the lack of adequate public policies for the Amazon and the changes in the hydrological regime of the Tocantins river is causing the increased practice of fishing and affecting the availability of fish in the river Tocantins. The complexity of the organization of social relations organized on the river Tocantins, leads to discuss the forms of ownership and management of water resources, the ecological approach, also reflecting the social and economic survival of cores and locations. It is in this context that this paper we show the perceptions of fishermen living along the river on the productivity of fish on the Tocantins river in Marabá. Thus, we applied semi-structured questionnaires in the main fishing communities living on the left bank of the Tocantins river in the urban area of Marabá (neighborhoods Francisco Coelho, Santa Rita and Santa Rosa) at random. The fishermen felt that the construction of hydroelectric Tucuruí was the main cause of reduced productivity of fish in the region, and, furthermore, lack of state action in order to qualify this activity according to local interests.   KEY-WORDS: ambient impacts, social organization, water resources.
