“…The diversity and composition of fish from streams is not fully known (Casatti 2001), however the predominance of Characiformes and Siluriformes in lotics reflects its greater representation in the neotropical ichthyofauna of freshwater systems (Lowe-McConnell 1999;Castro 1999 (Britski et al 2007;Teresa et al 2010;Pacheco et al 2012) and Uruguay Basin (Teixeira-de Mello et al 2011).…”

Abstract:The fish fauna of urban streams is still poorly known, it difficult to assess the effects of urbanization expansion on fish species composition, for this reason the aim of this study was to provide a checklist of species that compose the ichthyofauna of six urban streams, tributaries to the Vermelho River, upper Paraguay River Basin, Rondonópolis, Mato Grosso State, Brazil. The samples were performed with seine nets on a spatial gradient of 75 m, and with sieves for a period of 15 minutes in each site. A total of 56 species belonging to five orders, Characiformes, Siluriformes, Gymnotiformes, Cyprinodontiformes, and Perciformes, 21 families and 44 genera were sampled. The most common species were Astyanax asuncionensis Géry, 1972, Astyanax abramis (Jenyns, 1842), Odontostilbe pequira (Steindachner, 1882), Odontostilbe paraguayensis Eigenmann & Kennedy, 1903, Characidium zebra Eigenmann, 1909 and Hypostomus sp. This checklist brings additional knowledge on fish that inhabit tributaries to the major rivers of northern Pantanal.

“…We emphasize that none of the sampled species are on the Brazilian Red List. The higher number of species registered in this study is probably due to the environmental heterogeneity (Teresa et al, 2010). However, the diversity may have been underestimated.…”

This study presents an inventory of the ichthyofauna of the lower Roosevelt River sub-basin and its associated tributaries. Fish sampling with fishing nets and measurements of environmental parameters of water occurred in November/2012 (rising water), February/2013 (flooding), May/2013 (falling water) and August/2013 (drought). Depth mean was 8.86 m, water transparency was 0.6 m, conductivity was 22.7 µS.cm-1, pH was 6.59, dissolved oxygen was 7.63 mg.l-1 and temperature was 28°C. The total estimated capture area was 68,829.6 m2 during 2,880 hours. The catch per unit Effort (CPUE) was 0.37 individuals m-2.day-1. Species were spatially aggregated in all sampling points and river water levels. A total of 5,183 individuals distributed in 7 orders, 29 families, 104 genders and 188 species were sampled in this survey. The diversity index was 4.121 and equitability index was 0.789. The Characiforms order was the most abundant with 106 species, followed by Siluriforms with 63 species and Cichliforms with 23 species. The most abundant species was Serrasalmus rhombeus (Linnaeus, 1766) with 327 individuals (5.9%), followed by Chalceus epakros (Cope, 1870) with 309 individuals (5.6%) and Acestrorhynchus microlepis (Schomburgk, 1841) with 250 individuals (4.5%). Trophicity was characterized by omnivorous (28.6%), piscivorous (14.3%), carnivorous (13.8%) and detritivorous (12.8%). According to IBAMA's regulation, 29.25% of captured species presents ornamental potential.

“…However, M. leniceae seems to be not common in the flooded area, occurring preferentially in small streams, as can be inferred from collection localities. Besides that, the species is possibly rare, as noticed by its absence in surveys of fish species for that region (Willink et al, 2000;Teresa et al, 2010;Severo-Neto, 2015).…”

A new species of Microglanis from upper rio Paraguay basin is described. The species differs from congeners by the following combination of characters: deeply forked caudal fin with pointed lobes, bifurcated hook between antrorse and retrorse hooks on anterior margin of pectoral-fin spine, lateral line relatively long, surpassing the vertical through end of dorsal fin but not reaching adipose fin, color pattern of dorsal region of head dark brown with a restrict thin light area between anterior nostril and eye, broad light stripe on supraoccipital region. Uma nova espécie de Microglanis da bacia do alto rio Paraguai é descrita. A espécie difere das congêneres pela seguinte combinação de caracteres: nadadeira caudal profundamente furcada com lobos pontiagudos, serra bifurcada entre as serras antrorsas e retrorsas da margem anterior do espinho da nadadeira peitoral, linha lateral relativamente longa, ultrapassando a vertical que passa pelo final da base da nadadeira dorsal, mas não atingindo a nadadeira adiposa, padrão de colorido da região dorsal castanho escuro com uma estreita área clara restrita entre a narina anterior e o olho, faixa clara larga na região supraoccipital.
