Resumo: Moenkhausia intermedia is a small-sized important prey for other species of fish, birds and other carnivores that inhabit the floodplain, and it is an important link in the tropic web of this ecosystem. The aim of this study was to estimate the growth parameters, time of recruitment and mortality of M. intermedia, in the floodplain of Upper Paraná river. The samples were carried out monthly from March 1993 to February 1994, using dragnets. The results of the growth parameters, recruitment and mortality were assessed using “Compleat ELEFAN” program. The assintotic length estimate was 10cm and the growth rate (K) 0.30. The recruitment pattern presented two annual pulses related to the reproductive period of the species. Total mortality was 4.88, which is considered extremely high

Espécies com importância similar são pouco estudadas, portanto, este estudo teve por objetivo a estimativa dos parâmetros de crescimento, de recrutamento e de mortalidade do pequi M. intermédia, na planície de inundação do alto rio Paraná, na tentativa de identificar a real importância dessa espécie. As coletas foram realizadas mensalmente, durante o período de março de 1993 a fevereiro de 1994, por meio de arrastos. Os parâmetros de crescimento, de padrão de recrutamento e de mortalidade foram calculados usando o programa “Compleat ELEFAN”. O comprimento assintótico estimado (L∞) foi de 10cm e a taxa de crescimento (K) de 0,30. O padrão de recrutamento apresentou dois pulsos anuais, relacionados com o período reprodutivo da espécie. O valor da mortalidade total foi de 4,88, sendo considerada extremamente elevadaUniversidade Estadual De Maringá2008-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/202010.4025/actascibiolsci.v25i2.2020Acta Scientiarum.
