Fish species (Osteichthyes: Actinopterygii) from two tributaries of the Rio do Peixe basin, Tupã municipality, São Paulo state, Brazil

Abstract

Abstract:The Rio Pitangueira and the Ribeirão Santa Terezinha are right margin affluents of the Rio do Peixe, upper Rio Paraná basin, São Paulo state, Brazil. Fourteen non-temporally standardized samplings were made at four sampling sites along the Rio Pitangueira and at one sampling site on Ribeirão Santa Terezinha using cast nets, trawl net, hand net, and fishing rod and hook. Thirty fish species were collected, belonging to five orders, 13 families, and 25 genera. Of these, one is probably new to science and one is a rare species.

A new inventory for fishes of headwater streams from the rio das Cinzas and rio Itararé basins, rio Paranapanema system, Paraná, Brazil

“…With the predominance of Siluriformes and Characiformes, the taxonomic composition of the 24 sampled streams follows the pattern described for the Neotropical freshwater fish fauna (Castro 1999 recorded in Characidae, Loricariidae, and Heptapteridae also follows the pattern of the most species-rich families in the upper rio Paraná system (Langeani et al 2007). Similarly, several studies have indicated the prevalence of these families in other streams of this drainage system (e.g., Hoffmann et al 2015;Bifi et al 2017;Batista-Silva et al 2018;Claro-García et al 2018;Azevedo-Santos et al 2019b), especially for streams of the rio Paranapanema system, such as the rio das Cinzas (Costa et al 2013) and the rio Itararé (Cetra et al 2016) basins.…”

Ichthyofauna from three streams of the lower Iguatemi River in the upper Paraná river basin, Brazil

“…The families with the highest number of species in our study (Characidae, Heptapteridae, and Loricariidae) were also reported by Langeani et al (2007) as the most species-rich in the upper Paraná river basin. Similarly, several studies have indicated the prevalence of these families in other streams of this basin (Casatti et al 2001, Cunico et al 2009, Súarez and Lima-Júnior 2009, Felipe and Súarez 2010, Pereira et al 2014, Frota et al 2016, Bifi et al 2017. In addition, the most representative species in number of individuals, P. harpagos, A. aff.…”

Ichthyofauna of the ribeirão Sucuri, tributary of rio Tietê, upper rio Paraná basin, southeastern Brazil

“…Our study, combined with that of Serra et al (2015), reported 55 species from the Tietê-Batalha sub-basin and this association contributes to the understanding of the species structuring in the river basin. This provides valuable data for current and future conservation efforts as preconized by Bifi et al (2017), in response to increasing and accelerate processes of natural habitat losses in the São Paulo state and the consequent damage to the ichthyofauna (Oyakawa and Menezes, 2011).
