Resumo: | Although the rio Capivari basin is recognized as an area of great importance for the ichthyofauna, it lacks virtually every basic requirement for the definition of appropriate conservation strategies, since not even its species composition is known. The objective of this work is to determine the composition and distribution of fish species in the upper rio Capivari basin, relating them to the local physical features, and to evaluate the effectiveness of proposed conservations units, delimited based on areas of native vegetation remains, on the conservation of local ichthyofauna. During 2007, 50 different watercourses were sampled with gillnets, cast nets and kick nets. A total of 1308 individuals belonging to 41 species were captured. Degree of conservation, altitude and width were the parameters that best explained fish species richness. Considering the recently proposed boundaries for potential conservation units in the region only 15 or 20 out of 41 species would be found in the State Park and Environmental Protection Area respectively. In practice, the proposed conservation units would not be effective tools for fish conservation, since it would be located in mountainous areas of high altitude, of headwaters streams and where few species are found. In such context, the conservation of specific stretches of larger rivers is critical. |

O presente trabalho teve como objetivo geral determinar a composição e distribuição das espécies de peixes do alto rio Capivari e relacioná-las com as características físicas locais. Adicionalmente, avaliou-se a efetividade da implantação de unidades de conservação, que tiveram seus limites propostos com base na presença de remanescentes de vegetação nativa, para a conservação da ictiofauna local. Durante o ano de 2007 foram amostrados 50 diferentes cursos d'água na bacia com redes de emalhar, tarrafas e peneiras. Foram capturados 1308 indivíduos pertencentes a 41 espécies. O grau de conservação, a altitude e a largura foram os parâmetros que melhor explicaram a riqueza de espécies de peixes. Caso os limites de uma futura unidade de conservação fossem baseados nas manchas de vegetação remanescentes, apenas 15 ou 20 das 41espécies seriam encontradas na área do Parque Estadual ou da Área de Proteção Ambiental, respectivamente. Na prática, as áreas protegidas propostas não constituiriam ferramentas eficazes para a conservação de peixes, principalmente porque se situariam em áreas montanhosas, de grande altitude, abrigando apenas cabeceiras de rios, onde poucas espécies são encontradas. Dentro deste contexto, a conservação de trechos específicos de rios de maior porte é fundamental.Sociedade Brasileira de Ictiologia (SBI)2020-03-27T13:39:47Z2020-03-27T13:39:47Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPOMPEU, P. dos S. et al.
