Contraste entre o manejo pesqueiro na Orinoquia venezuelana e na Amazônia brasileira

Abstract

As bacias do Orinoco e do Amazonas são similares, no sentido de que os dois rios correm em paralelo, em direção ao Oceano Atlântico, têm origem geológica similar e ictiofauna que se sobrepõem quanto ás espécies. O manejo, os impactos socioculturais e o ordenamento jurídico pesqueiro historicamente adotados para se realizar uma pesca responsável, foram revisados nesta dissertação para a Orinoquia venezuelana e Amazônia brasileira. Embora haja diferentes tipos ou estratégias de manejo de recursos naturais e de manejo da pesca em particular tais como: estratégias de manejo convencionais ou tradicionais, de manejo participativo ou comanejo, abordagem de conhecimento ecológico local, manejo adaptativo e mais recentemente o manejo com enfoque ecossistêmico, nesta dissertação foi feita uma análise comparativa para as duas bacias e examinada sua eficiência. Para este propósito se realizou o levantamento de dados secundários e séries históricas de desembarques, composição da frota pesqueira, principais espécies de peixes comerciais, cadeia de comercialização, aspectos técnico-pesqueiros e socioeconômicos dos pescadores das bacias de estudo. Foi realizada uma extensa revisão bibliográfica das características relevantes da Orinoquia venezuelana e da Amazônia brasileira, bem como seus aspectos biogeoquímicos e ecológicos.

The Orinoco and Amazonas river basins are similar, in the sense that the two rivers run in parallel, in direction to the Atlantic Ocean, they have similar geological origin and an overlapping fishfauna concerning their species. The socio-cultural impacts and the juridical basis for the management historically adopted for a responsible fishing were revised in this dissertation for the Venezuelan Orinoquia and the Brazilian Amazon. Although there are different types of natural resources management strategies and fisheries in particular as: conventional or traditional management strategies, participative or co-management, approach of local ecological knowledge, adaptive management and more recently the ecosystem approach. So in this dissertation a comparative analysis for the two basins was carried out and its efficiency was examined. For this purpose secondary data and historical series of landings, fishing fleet composition, main commercial fish species, commercialization chain, fisher´s socio-economic and technical aspects were examined. An extensive bibliographical revision of the important characteristics of Venezuelan Orinoquia accomplished and of the Brazilian Amazon was accomplished, as well as its biogeochemical and ecological aspects.
