Acesso em:.https://repositorio.ufpa.br/handle/2011/4482This work aims to analyze the knowledge of traditional communities in natural resource management through its productive activity, fishing approach of Reproductive Efficiency and Technological Trajectories notion, and thus valuing local knowledge, coupled with their territoriality constitution, as issues crucial to the success of collective management as a basis for sustainable development. Knowing traditional with the assumptions of reproductive efficiency, enabling a rational process and inherent agents that build productive strategies, grounded in multispecies, especially in the use of space and technology, the main mitigating action to ensure the sustainability of human activity in context Amazon. Because this was a study of a more qualitative, were analyzed: a) the historical formation of the city of Mocajuba fishing in the region Lower Tocantins, the natural foundations of spatial scenarios prevailing in research and aspects of rationality and standards production and reproductive performance of economic agents. The results showed us that the rationality of reproductive efficiency has proven effective in the analysis, with the value found in h converging to 1, in other words, the field shows that fishing provides comfort to those in work, represented in the modus vivendi of the agent, to reflect its form of social interaction that same scenario in capitalist societies are constituted, markedly, by its social bases family intertwined in the construction and reconstruction of the natural environment to sustain strong relationships of solidarity and cooperation as its core brands. The configuration of social organization fishing emphasized the model of bipolar division, determined by age and sex, seated in the domestic hierarchy and relationship of human productive force. Technological developments occurred in the Lower Tocantins, affected the fishing, and based on new quirk space optimization fishing. In this sense, technological changes, show up, reducing the effective execution time, increase stamina and enhance the productive yield, without thinking unlink conservation agent. It was evident that the fisheries conducted in the study area, is multispecific, developed dynamically in the different fishing methods employed at each annual seasonal cycle applied in different habitats. Thus, we conclude this paper that the ecological consciousness of the peasant and the value of traditional knowledge is paramount for successful fishing, however, this knowledge is often overlooked by the environmental authorities, but should be considered and consulted so that they can support measures for effective management environment to thrive.porAcesso AbertoPesca artesanalEconomia pesqueiraGestãoRibeirinhosRio Tocantins (Baixo)Mocajuba (PA)ParáAmazônia brasileiraDissertaçãoCNPQ::CIENCIAS SOCIAIS APLICADAS::ECONOMIA::ECONOMIAS AGRARIA E DOS RECURSOS NATURAIS
