| English abstract | The standard length of 7610 specimens of 43 species from eight streams of rio Tibagi basin was obtained in order to analyze the means of fish sizes. The higher mean size was observed in Gymnotus carapo Linnaeus, 1758 (165,5 mm) and the smaller, in Phalloceros caudimaculatus (Hensel, 1868) (16,25 mm). Some fish like Acestrorhynchus lacustris (Reinhardt, 1874), Leporinus obtusidens (Valenciennes, 1836), Gymnotus carapo Linneus, 1758 and Synbranchus marmoratus Bloch, 1795 can reach big or medium size when adults but were collected only young, evidencing they use some streams in beginning of life. The mean size of total species was 49,81mm, what shows the small size composition of fishes in the streams. The Kolmogov-Smirnov test comparing the mean size of all streams showed significant similar size both in upstream and downstream regions, independent to the different environmental conditions |
