Abstract: Abstract:We compiled data on fish fauna of the Ivaí River basin from recent specialised literature, standardised sampling and records of species deposited in fish collections. There were 118 fish species of eight orders and 29 families. Of these, 100 species are autochthonous (84.8%), 13, allochthonous (11.0%) and five, exotic (4.2%). The main causes for the occurrence of non-native species are escapes from aquaculture, introduction for fishing purposes and the construction of the Itaipu hydroelectric plant. T… Show more

“…This new update represents a nearly 120% increase in the number of species recorded in the basin since the last list was released. When comparing the ichthyofauna found in the basins located in the State of Paraná, the Piquiri River basin has an absolute richness of fish species that is higher than the richness of the Pirapó basin (76 species, Pagotto et al 2012), the Ivaí River basin (118 species, Frota et al 2016a), the upper and lower Iguaçu River basin (41 and 106 species respectively, Ingenito et al 2004, and the Tibagi River basin (151 species, Raio & Bennemann 2010). Approximately 49% of the species listed here were coincident with those recorded for the upper Paraná River (see Langeani et al 2007).…”

“…are shared, respectively, with the basins of the Jordão (lower Iguaçu River) and Ivaí (upper Paraná River) Rivers. The former species is reported as endemic to the Iguaçu River basin , while the latter is regarded as endemic to the upper Ivaí River basin (Frota et al 2016a). Therefore, the presence of these species in the Piquiri River basin suggests past connections between the upper courses of those basins that might have occurred prior to the uplift of Serra da Esperança, which caused the isolation of the respective headwaters (Frota et al 2016b).…”
