Abstract: Based on long-term studies in the upper rio Paraná basin, in addition to a broad review of literature and other information, we were able to identify 33 species of native fishes in the lower rio Paraná basin that successfully colonized the upper rio Paraná after Itaipu impoundment, that flooded the natural geographic barrier constituted by the Sete Quedas Falls. These species belong to six Orders, encompassing two of Myliobatiformes, six of Characiformes, 17 of Siluriformes, six of Gymnotiformes, one of Percif… Show more

“…Hoplias sp2 is a native species from the Upper Paraná River and Hoplias sp1 was introduced in this area after the formation of the Itaipu Reservoir and consequent flooding of Sete Quedas Falls, which formed a natural barrier between two hydrographic regions, and thus many endemic species of the lower stretch successfully colonized the Upper Paraná River (Pazza and Júlio Júnior 2003, Júlio Júnior et al 2009, Hauser and Benedito 2012. Samplings of fish tissues were performed quarterly from March to December 2007, using gill nets with different mesh sizes (2.4 to 16 cm between opposite knots), exposed on the banks of the sampling sites for 24 hours and inspected every eight hours.…”

“…The second regards the species' success in colonizing new environments, as verified in the Upper Paraná River floodplain, where L. platymetopon currently figures among the most abundant fish species (Luiz et al 2004, Agostinho et al 2004, Morales et al 2009). This species had spread from the middle Paraná River after the removal of the natural barrier of the Sete Quedas Falls, when it was flooded by the damming of the Itaipu reservoir in 1982 (Agostinho et al 1992, 1995, Luiz et al 2004, Júlio Júnior et al 2009). …”

“…K. moenkhausii was recorded in the Upper Paraná River basin only after the construction of the Itaipu hydroelectric power dam in 1982 [6]. The Itaipu Reservoir inundated an area of about 1350 km 2 [51] that included the Sete Quedas Falls, a natural and effective barrier that was the limit of the hydrographic basins of the Lower and Upper Paraná Rivers [6,52]. The inundation of Sete Quedas falls moved the barrier between these two hydrographic basins to 150 Km below the Itaipu Dam, allowing the mixing of species from the two basins.…”

“…The inundation of Sete Quedas falls moved the barrier between these two hydrographic basins to 150 Km below the Itaipu Dam, allowing the mixing of species from the two basins. At present, at least 33 species initially limited to the Lower Paraná River basin have successfully colonized the Upper Paraná River basin, including K. moenkhausii [52].…”
