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.

The growth of cities in the state of São Paulo has caused major impacts on aquatic ecosystems, as in Tatuí River, which is part of the Sorocaba River basin and MiddleTietê. Studies on its ichthyofauna are relevant to the conservation and monitoring of the river, under the optics of Tatuí river is one of the largest contributor to the pollution of the river Sorocaba. This study aimed to survey the fish fauna of the Tatuí river and relate them to anthropogenic interference which is submitted. Were collected during the dry and rainy seasons of 2010. Considering all the work already done on the Tatuí river were raised 53 species. This worked identified 18species of fish, belonging to 9 families and 2 orders. The most representative family was Characidae, with 5 species followed by the family Loricariidae, with 3 species. The most abundant species was Hypostomus margaritifer, followed by Hypostomus ancistroides. The result corroborates with other studies conducted in Paraná High and Sorocaba River basin. Inverse correlation was obtained between total dissolved solids and diversity. What is explained y the Tatuí river find themselves impacted throughout its length, especially the lack of riparian vegetation, siltation and domestic sewage and industrial.
Brazil is one of the countries with the greatest biodiversity on the planet, housing between 15 and 20% of the total number of species. Some of that wealth has been inexorably lost, therefore it is necessary to know in depth the natural heritage of the country, to identify the main factors that threaten them and set priorities for action. Knowledge, supported by scientific rigor, is a powerful tool to permanently engage the action of the public authorities in the planning and conservation which, consequently, may introduce more effective instruments of control, supervision and protection process. The Secretary of Environment, in order to subsidize and provide guidelines for environmental actions within the city, articulated with institutions and researchers, during the year of 2013, the theme “Biodiversidade do Município de Sorocaba” [“Biodiversity of the city of Sorocaba”], which resulted in two products published in the official newspaper of the city and a book). These represent important mechanisms that subsidize conservation efforts and environmental education. Keywords: Conservation; Municipality; Urban Ecosystems. Resumo: O Brasil é um dos países com a maior diversidade biológica do planeta, abrigando entre 15 e 20% do número total de espécies. Parte dessa riqueza tem sido perdida de forma inexorável, portanto, é necessário conhecer com mais profundidade o patrimônio natural do país, identificar os principais fatores que os ameaçam e estabelecer prioridades de ação. O conhecimento, respaldado no rigor científico, constitui instrumento poderoso para envolver de forma definitiva a ação do poder público no processo de planejamento e conservação que, assim, podem instituir instrumentos de controle, fiscalização e proteção mais eficazes. A Secretaria Municipal do Meio Ambiente de Sorocaba, com o objetivo de subsidiar e dar diretrizes às ações ambientais, no âmbito do município, articulou junto a instituições e pesquisadores, durante o ano de 2013, o tema “Biodiversidade do Município de Sorocaba” o que culminou em dois produtos (publicação no diário oficial do município e um livro) sendo estes importantes mecanismos que subsidiarão ações de conservação e educação ambiental. Palavras-chave: Conservação; Municipalidade, Ecossistemas Urbanos.
