In this paper we present a list of the fish fauna of Sorocaba river sub-basin. Fish were caught with gillnets, sieves and puçás, a sort of funnel net. We listed 71 species, distributed in 7 orders, 22 families and 50 genera. Characiformes are represented by 39 species, Siluriformes 21, Perciformes 4, Gymnotiformes 3, Cyprinodontiformes 2, and Synbranchiformes and Cypriniformes by a single species each. Five species are alien. Nine species remain as an indefinite taxonomical status.

A contaminação do combustível é uma importante fonte de contaminação do solo por hidrocarbonetos. O hidrocarboneto provoca a perda de nutrientes que torna o solo infértil, além de ter caráter mutagênico e carcinogênico. O processo de biorremediação pode ser com a utilização de microorganismos, plantas ou produtos biológicos, tais como enzimas de componentes e de células. A técnica é feita in situ ocorre no local do derramamento, que é feita por bioestimulação, bioaumento, atenuação natural. A técnica ex situ ocorre quando o material é removido a partir do local e levadas para o laboratório para ser tratada; entre as técnicas ex situ pode ser citada a compostagem e reatores naturais. A técnica in situ é mais comumente usado por causa das dificuldades, riscos e custos elevados de transporte do material contaminado.

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

The Itupararanga Reservoir is located at the Sorocaba River Basin, São Paulo State, Brazil. Five cities use the waters of this reservoir for human consumption. Despite this intensive use of the water resource, no study has been undertaken on the ichthyofauna of this reservoir. Collections were performed in nine sampling stations, where each three were located in the riverine, transitional and lacustrine zones. Fish specimens were collected using eight monofilament gillnets of 10 m length each, with varied mesh sizes, in the rainy and dry seasons, which corresponded to our spatial scale of analysis. Overall, 14 species of fish were identified, with the highest contribution from Characidae and Curimatidae. The most abundant species were: the "lambari", Astyanax fasciatus, the "saguiru", Cyphocharax modestus, the "lambari bocarra", Oligosarcus paranaensis, and the "mandi", Iheringichthys labrosus. Diversity tended to be higher during the dry season, although the difference was not statistically significant. Cluster analysis identified four season sampling groups differentiated by within-season distribution of species. Mantel's test showed that this distribution was little affected by environmental factors, suggesting that biotic factors were more important in determining the species distribution within the reservoir.
