“…The highest richness of the Siluriformes and Characiformes, as well as the families Characidae and Loricariidae, is a common observation in streams in the Neotropics (Lowe-McConnell 1999, Shibatta et al 2002, Buckup et al 2007Langeani et al 2007), and corroborates studies in small streams in other basins of the Paraná State (Galves et al 2007, Cunico et al 2009Gubiani et al 2010, Araújo et al 2011, Pagotto et al 2012, Delariva & Silva 2013. However, for the lower Iguaçu River, were registered 11 Astyanax spp., popularly known as "lambari", of which eight species are endemic, and two possibly endemic to this basin ( Baumgartner et al 2012).…”

Abstract:The drainages of the Iguaçu River basin, as well as the main channel of the river, have peculiar characteristics resulting from geomorphological processes in this area, including the formation of the Iguaçu River Falls. This slope in the lower portion of the basin is a biogeographical barrier to many organisms. In this study was inventoried the fish fauna of streams of the lower Iguaçu River basin, evaluating possible differences in the species composition upstream and downstream of this biogeographical barrier. Sampling were conducted between 2004 and 2013, in five streams, three upstream and two downstream of the Iguaçu River Falls, using electrofishing. The nMDS analysis was run to investigate possible groupings of similar fauna between the streams sampled. The scores of this test were tested as to the significance of groupings with the Hotelling T 2 test. The indicator value method (IndVal) was used to detect the distribution of species among the groups of the streams upstream and downstream of the Iguaçu River Falls. We collected 18,908 individuals of six orders, 11 families, and 40 species. Siluriformes and Characiformes had the highest species richness; Cyprinodontiformes presented the highest abundance. Considering the species recorded, 21 are considered natives to the Iguaçu River basin, including 15 endemic, wich were found only in streams upstream of the falls. Additional 18 species were verified only in the streams downstream of such barrier. Four species were common to both stretches. The axis 1 of the nMDS separated two groups: streams upstream (S1, S2 and S3) and streams downstream of the Iguaçu River Falls (S4 and S5). The indicator species analysis also indicated a distinction between the groups of streams, that were significantly different (Hotelling's T 2 = 234.36, p ˂ 0.0001). The number of endemic species in the streams upstream of the Falls (15 spp.) evidences a significant effect of isolation promoted by the Iguaçu River Falls, and confirms the role of this barrier in the vicariant processes and endemism typical of this basin. These results emphasize the importance of conserving these ecosystems, once the extinction of species in this region means the irreversible loss of them. Resumo: As drenagens da bacia do rio Iguaçu, bem como o canal principal do rio, possuem características peculiares resultantes de processos geomorfológicos dessa área, incluindo a formação das Cataratas do rio Iguaçu. Esse desnível na porção inferior da bacia constitui uma barreira biogeográfica para muitos organismos. Neste trabalho inventariamos a fauna de peixes de riachos na porção do baixo rio Iguaçu, avaliando possíveis diferenças na composição de espécies acima e abaixo dessa barreira biogeográfica. Entre 2004 e 2013, foram amostrados cinco riachos, sendo três localizados acima das Cataratas do Iguaçu e dois abaixo, por meio de pesca elétrica. Para investigar possíveis padrões de agrupamentos de fauna similares entre os riachos amostrados foi

“…The results of other recent inventories conducted in different sub-basins of the Paranapanema River (Cetra et al 2012;Cionek et al 2012;Pagotto et al 2012) and this study together indicate that the ichthyofaunal diversity of the Paranapanema River is currently underestimated and is likely to undergo a considerable increase in its fish species richness as more studies are conducted.…”

Several studies of small watersheds of in the Upper Paraná River basin are currently available. However, the number and extent of its tributary streams still pose a challenge to enhancing current knowledge of their ichthyofauna. This study aimed to survey the fish fauna of three streams of the Lower Paranapanema River basin, state of Paraná, Brazil (Capim, Tenente and Centenário streams). The sampling included 3,167 specimens belonging to five orders, 17 families and 56 species. The streams presented differences in species richness (Centenário Stream: 41 species; Tenente Stream: 33 species; Capim Stream: 30 species). Two species occurred at all collection sites (Astyanax bockmanni and Hypostomus ancistroides). Nine non-native species were recorded, four of them found exclusively in the Centenário Stream.

“…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).…”

Knowledge of the fish species in river basins is among the minimum requirements for the management of water and fish resources. Therefore, the aim of this study was to update the fish species composition of the Piquiri River basin, upper Paraná River basin. Data were gathered from recent information published in specialized literature and records for ichthyology collections. This update reports the occurrence of 152 fish species distributed in 8 orders, 31 families, and 89 genera. Non-native species accounted for 20% of all species, and the construction of the Itaipu Power Plant and its fish ladder were the main vectors of introduction. Three percent of the species were endangered, and 11% were classified as migratory. The Piquiri River basin harbors a large number of species, some of which are rare, endangered, migratory, endemic, and even unknown by science. Because of this, maintaining the integrity of this river basin will support the persistence of regional biodiversity. Keywords: Ichthyofaunal survey, species knowledge, preservation, upper Paraná River basin.Atualização da ictiofauna da bacia do rio Piquiri, Paraná, Brasil: uma área prioritária para conservaçãoResumo: O conhecimento das espécies de peixes existentes em uma bacia hidrográfica é condição mínima necessária para a implantação de qualquer medida de manejo dos recursos hídricos e pesqueiros. Dessa forma, o objetivo deste estudo foi realizar uma atualização da composição das espécies de peixes da bacia do rio Piquiri, sistema do alto rio Paraná, proveniente de recentes informações contidas em estudos divulgados na literatura especializada e registros de espécies depositadas em coleções ictiológicas. A atualização do levantamento ictiofaunístico da bacia do rio Piquiri revelou a ocorrência de 152 espécies, as quais foram distribuídas em oito ordens, 31 famílias e 89 gêneros. Vinte por cento das espécies foram consideradas não nativas. O principal vetor de introdução foi a construção da barragem de Itaipu e seu sistema de transposição. Três por cento das espécies apresentaram alguma ameaça de extinção e 11% foram classificadas como migradoras. A bacia do rio Piquiri comporta grande número de espécies, algumas delas raras, ameaçadas de extinção, migradoras, endêmicas e até mesmo desconhecidas pela ciência. Dessa forma, a manutenção da integridade da bacia promoverá a persistência da biodiversidade regional. Palavras-chave:Levantamento ictiofaunístico, conhecimento das espécies, preservação, bacia do alto rio Paraná.
