Resumo: A paradigm is characterized as a network of conceptual, instrumental, and methodological commitments that guides the direction and methodology of scientific research. Thus, a paradigm defines what should be studied, what questions should be asked, what tools should be used, and what rules should be followed in interpreting results. The aim of this paper is to analyze how fisheries management emerged and developed in Brazil, considering that science’s progress as a series of paradigms. Management actions related to reservoir fishery are not frequent in Brazil and, when applied, they did not generate good results, because they usually were based on poor technical and scientific information or in paradigms developed in the temperate region (North America). Fish passages (ladders) were the first attempt to minimize the impacts of damming, followed by regulation of fishery and stocking programs. However, it seems that the paradigm that led the researches (imported from the United States) was not appropriated for reservoir management in most Brazilian reservoirs. We agree that some other reasons contributed in some extension to the failure of management actions: i) inadequacy and insufficient data availability; ii) inappropriate approach used to perform management; iii) absence of monitoring studies; iv) policy inadequacies; and v) deficiencies in the integration among the hydroelectric companies. Recently, hydroelectric companies started to develop research in basic limnology and fish, in order to improve data quality to better support reservoir fishery management actions. We suggest that this situation is happening or maybe happened in other countries in South America and other parts of the world

Portanto, o paradigma define o que seria estudado, quais as questões a serem perguntadas, quais ferramentas seriam usadas e quais as normas a serem seguidas na interpretação dos resultados. O objetivo desse estudo é analisar como o manejo da pesca emergiu e se desenvolveu no Brasil considerando o progresso da ciência como uma série de paradigmas. Ações de manejo relatadas para a pesca não são freqüentes no Brasil e quando aplicadas não apresentaram bons resultados, porque usualmente foram baseadas em informações técnicas e científicas inadequadas ou em paradigmas desenvolvidos em regiões temperadas. As escadas de peixes foram as primeiras tentativas para minimizar os impactos dos barramentos, seguidas pela regulação da pesca e peixamentos. Entretanto, parece que o paradigma que norteava estas pesquisas (importados dos Estados Unidos da América) não foi apropriado para o manejo de reservatório na maioria do território brasileiro. Além disso, outros motivos podem ter contribuído para alguns fracassos das ações de manejo, tais como: i) dados disponíveis inadequados e insuficientes; ii) a abordagem inadequada usada para realizar o manejo; iii) ausência de estudos de monitoramento; iv) políticas inadequadas e v) deficiência na integração entre as companhias hidrelétricas. Recentemente, as companhias hidrelétricas começaram a desenvolver pesquisas em limnologia e ictiologia com o propósito de obter informações para dar uma maior fundamentação científica as ações de manejo da pesca em reservatórios. Aparentemente, situação similar a do Brasil pode estar acontecendo em outros países da América do Sul e outras partes do mundoUniversidade Estadual De Maringá2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/154510.4025/actascibiolsci.v26i3.1545Acta Scientiarum.
