Resumo: Two fish species, known as lambaris (Astyanax altiparannae and A. fasciatus) were collected from the following streams in Londrina: Cambé (lake Igapó IV), Três Bocas, Apertados and Capivara. After capture blood samples and gills were immediately removed. Gills were fixed in Bouin and processed for light microscopy. A small amount of blood was used for hemoglobin determination and sodium and glucose plasma concentrations were determined after blood centrifugation. Animals from Cambé and Capivara streams showed certain severe histopathological alterations, such as lamellar aneurism and epithelial lifting. These fish also showed higher blood sodium concentration and a reduction of blood glucose when compared to fish from Três Bocas stream. Fish from Capivara showed a decrease in hemoglobin content when compared to animals from Cambé stream. Higher incidence of histological and physiological alterations observed in fish from Cambé and Capivara stream clearly indicates the animals’ health impairment

Imediatamente após a coleta dos peixes, amostras sangüíneas e brânquias foram retiradas. As brânquias foram fixadas em Bouin e processadas para microscopia óptica. Do sangue coletado uma alíquota foi utilizada para dosagem de hemoglobina e o restante foi centrifugado para a determinação da concentração plasmática de sódio e glicose. Os animais provenientes do Cambé e Capivara apresentaram alterações histopatológicas severas, tais como: aneurisma lamelar e elevação epitelial. Estes animais também mostraram maior teor plasmático de sódio e redução da glicemia quando comparados com os peixes do Três Bocas. Os lambaris provenientes do Capivara apresentaram decréscimo significativo do conteúdo de hemoglobina em relação aos animais coletados no Cambé. A maior incidência de alterações histológicas e fisiológicas nos lambaris procedentes do ribeirão Cambé e do córrego Capivara indica claramente o comprometimento da saúde destes peixes e da qualidade da água destes locaisUniversidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/270810.4025/actascibiolsci.v23i0.2708Acta Scientiarum.
