Resumo: | The building of Itaipu Dam, 150 km downstream from Sete Quedas Falls, resulted in the natural geographical barrier drowning, with subsequent mixing of the fish faunas. Serrasalmus marginatus (Osteichthyes, Serrasalmidae), a species that had been restricted to the river segment downstream from Sete Quedas, invaded the Upper Paraná River. The catching of Serrasalmus spilopleura, a resident species, decreased drastically after the invasion, contrary to S. marginatus, which increased in abundance. In the Piquiri River, where the latter species does not occur, the abundance of S. spilopleura remained high, due to the presence of Nhá Bárbara and Apertado Falls. |

Serrasalmus marginatus (Osteichthyes, Serrasalmidae), uma espécie que apresentava distribuição restrita ao segmento a jusante de Sete Quedas, invadiu o alto rio Paraná. A captura de Serrasalmus spilopleura, uma espécie residente, diminuiu drasticamente após a invasão, ao contrário de S. marginatus que aumentou em abundância. No rio Piquiri, onde a espécie invasora não ocorreu, a abundância de S. spilopleura permaneceu alta por causa das quedas de Nhá Bárbara e Apertado.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/231010.4025/actascibiolsci.v24i0.2310Acta Scientiarum.
