| Popis: | This study investigates the distribution and structure of the assemblages of fishes in tributaries of middle and lowersections of Tibagi river basin. The samples were conducted quarterly from December 2013 through December 2014,in 24 sampling sites of 8 tributaries. A total of 5643 individuals belonging to 44 species distributed in 13 families and5 orders are reported. The families Characidae, Loricariidae, and Heptapteridae were predominant; Astyanax paranae,Phalloceros harpagos, Piabina argentea, Astyanax bockmanni, and Trichomycterus davisi were the most abundantspecies. Four non-native species were collected: Coptodon rendalli, Poecilia reticulata, Xiphophorus hellerii, andOreochromis niloticus.
