A gestão das pescarias da piramutaba (Brachyplatystoma vaillantii - Valenciennes, 1840) no estuário Amazônico, Pará: situação atual e perspectivas

Abstract

The piramutaba (Bachyplatystoma vaillantii) is a species of catfish that performs long migrations in white water rivers of the Amazon basin. It is currently one of the most catfish caught by fishing in the estuary has industrial features. This species is found in growth overfishing, a fact noted by the continuous decrease in the average size of individuals captured. Considering the economic and ecological importance of this species, this study aims to identify the environments, the intensity of their production and management in the Amazon Estuary. The study area includes four counties that belong to the State of Pará (Salvaterra, Soure, Vigia and Belém). Information used in this study was obtained from literature searches and questionnaires to stakeholders of the fisheries. The results showed that the piramutaba is exploited by both industrial and artisanal fisheries in the area of the Amazon Estuary. The production of fisheries in the area totaled 16,063.50 tons in 1999, fell to 12,010.00 tons in the following year and reached peak production of 24,701.00 tons in 2006. The trend analysis of production as the actors assessment of fishing stocks indicates a decrease in the last 10 years and the future prospects for the production of artisanal fisheries and industrial point there will be reduced landings in the area of the estuary.
