“…This shows both the homogeneity in fish species distribution across the Pantanal floodplain, and the importance of aquatic macrophytes for maintenance of fish diversity. Moreover, the predominance of Characiformes and Siluriformes observed follows the Neotropical biogeographic pattern and other studies in the Pantanal (Willink et al 2000, Súarez et al 2001, Baginski et al 2007, Pacheco & Silva 2009, Milani et al 2010.…”

“…The dominance of two small species of Cheirodontinae (O. pequira e O. paraguayensis) follows a habitat pattern, since other studies on fishes associated with aquatic macrophytes have yield the same general results (Súarez et al 2001, Baginski et al 2007, Pacheco & Silva 2009. This suggests that the macrophyte habitat is favorable for these species, probably because of the good availability of food and protection from predators.…”

“…Some studies have been carried out in the northern Pantanal (Baginski et al 2007, Pacheco & Silva 2009, Fernandes et al 2010, Milani et al 2010, Lourenço et al 2012) and the central region (Súarez et al 2001(Súarez et al , 2004; however few data are available from the southern Pantanal. This study aimed to characterize the composition of fish species associated with aquatic macrophytes in Porto Murtinho Pantanal, near the limit of the Upper Paraguay River.…”

Assemblage of fish species associated with aquatic macrophytes in Porto Murtinho Pantanal, Mato Grosso do Sul, Brazil

Abstract:The Porto Murtinho Pantanal lies at the limit of the Upper Paraguay River basin, and despite its biogeographical importance, several aspects of the ecology of the fish assemblage are not known. Monthly samples of fish associated with aquatic macrophytes were taken from February 2009 through January 2011. A total of 46,327 individuals were collected, belonging to 144 species. Characiformes and Siluriformes were the predominant orders, and Odontostilbe pequira, O. paraguayensis and Bryconamericus exodon were the most abundant species. Two species, Cynopotamus sp. and Pimelodus mysteriosus, were recorded for the first time in the Pantanal, and a new occurrence record of Cichla piquiti was observed, representing an approximately 400 km range expansion in your distribution area in the Pantanal.

“…The higher abundance of Characiformes species, especially in habitats where macrophytes are present, has been documented in many other Neotropical river basins (Delariva et al, 1994;Meschiatti et al, 2000;Casatti et al, 2003;Petry et al, 2003;Pelicice et al, 2005;Pacheco and Da-Silva, 2009). The species G. brasiliensis (Perciformes) and G. carapo (Gymnotiformes) are also very common in macrophyte areas (Vono and Barbosa, 2001;Petry et al, 2003).…”

To evaluate the effects of macrophytes presence in the structure of littoral fish assemblages in the littoral zone, monthly samples were collected from September, 2006 to August, 2007 in an impounded tributary of the Itá Reservoir, the Fragosos River, located in the Upper Uruguay River Basin. Fish were collected using a beach seine and sampling was conducted in the littoral zone inside a macrophyte stand and in an area with no macrophytes. A total of 5,191 fish were captured during the study period. Fish assemblage attributes (fish abundance, species richness, and diversity) varied significantly between sampling months and areas. The abundance of Astyanax cf. bimaculatus, Astyanax fasciatus, Geophagus brasiliensis, and Gymnotus carapo also varied significantly between sampling months and areas. Detrended Correspondence Analysis showed a clear spatial segregation at the first axis and a slight temporal segregation at the second axis. These results were confirmed by Multiple Response Permutation Procedure analysis. Apparently, the presence of the aquatic macrophytes is not the only factor influencing the distribution of littoral fish assemblages in the Fragosos River. Littoral fish seem to be taking advantage of low-to medium-sized macrophyte stands, but few species used maximum-sized stands.Keywords: fish assemblage, aquatic macrophytes, Itá reservoir, Upper Uruguay River. Estrutura da assembleia de peixes litorâneos em um tributário represado:os efeitos da presença de macrófitas (região subtropical, Brasil) ResumoBuscando-se avaliar os efeitos da presença de macrófitas na estrutura da assembleia de peixes litorâneos, foram realizadas coletas mensais (setembro/2006 a agosto/2007) na região lêntica de um tributário represado pelo reservatório de Itá (Rio Uruguai, Brasil), o Rio Fragosos. As amostragens foram realizadas com uma rede de arrasto na zona litorânea dentro do banco de macrófitas e em áreas sem macrófitas. Os peixes coletados foram identificados e submetidos a uma biometria. Para caracterizar os locais amostrados, foi avaliada a qualidade da água e estimada a área de cobertura do banco. Foram capturados 5191 indivíduos durante todo o período de estudo. Os atributos da assembleia analisados variaram significativamente entre os meses e os locais amostrados, assim como a abundância das espécies Astyanax cf. bimaculatus, Astyanax fasciatus, Geophagus brasiliensis e Gymnotus carapo. A Análise de Correspondência Destendenciada mostrou uma forte segregação espacial e uma leve segregação temporal. Esses resultados foram confirmados pela análise de permutação múltipla -MRPP. Aparentemente, a presença das macrófitas aquáticas não é o único fator que está influenciando a distribuição da assembleia de peixes do rio Fragosos, a qual parece estar se beneficiando do banco de macrófitas em períodos de baixa e média cobertura vegetal, sendo que poucas espécies utilizam esse ambiente quando o banco se torna maior.Palavras-chave: assembleia de peixes, macrófitas aquáticas, reservatório de Itá, Alto Rio Uruguai.

“…However, the total number of species would likely be higher if the plateau streams had been included (Alho & Sabino 2012). Numerous studies have been carried out in the basin over the past two decades, including the floodplain region (Catella & Petrere-Jr 1996, Willink et al 2000, Junk et al 2006, Baginski et al 2007, Pacheco & Silva 2009, PainsSilva et al 2010, Pains-Silva et al 2014, Polaz et al 2014, Botini et al 2015and Severo-Neto et al 2015 and plateau waters (Súarez et al 2007, Terra & Sabino 2007, Casatti et al 2010, Castro & Vizzotto 2013, Krinski et al 2015and Oliveira et al 2015. In studies of the plateau portion of the basin, analyses at small spatial scales were the predominant.…”

Survey of fish species from plateau streams of the Miranda River Basin in the Upper Paraguay River Region, Brazil

et al. 2017

The objective of this study was to provide a comprehensive list of the fish fauna of headwater streams of the Miranda River in the Upper Paraguay River Basin. Our primary data set was constructed from sampling of fish using a rectangular sieve, trawl, and gill nets from 2004 to 2015. Our secondary data were derived from published reports conducted in the Miranda River Basin, in addition to taxonomic and distribution data from other studies conducted in the basin. All data were compiled, which in the end encompassed a period from 1999 to 2015. The datasets yielded a total of 143 species, 104 from the primary data (72.7%) and 39 from the secondary data (27.3%). Species were distributed among seven orders and 30 families were found in the Miranda River Basin. Characiformes and Siluriformes were the predominant orders, and the families Characidae and Loricariidae had the greatest number of species. Our results indicate a greater number of species compared to other studies of the Upper Paraguay Basin headwaters, likely due to the longer time frame covered by our primary and secondary datasets.
