Resumo: | The present work studied protozoan parasites of cultivated fishes (N = 433) from two feefishing farm situated in Franca, São Paulo, Brazil, during a period of April 1997 through March 1999. Specimens of piauçú Leporinus macrocephalus Garavello &amp;amp; Britski, 1988 (Anostomidae), pacu Piaractus mesopotamicus Holmberg, 1887 (Characidae) carp Cyprinus carpio Linnaeus, 1758 (Cyprinidae), Tillapia rendalli Boulenger, 1896 (Cichlidae), nile-tilapia Oreochromis niloticus Linnaeus, 1758 (Cichlidae), matrinxã Brycon cephalus Günther, 1869 (Characidae) and tambacu hybrid (male of P. mesopotamicus x female of Colossoma macropomum Cuvier, 1818) were collected. The fishes were parasitized with protozoans Ichthyophthirius multifiliis Fouquet, 1876 (Protozoa), Trichodina sp. and Piscinoodinium pillulare (Schaperclaus, 1954), Lom, 1981 (Protozoa). In the cold season (autumn and/or winter) all species of fish were infected with I. multifiliis. Higher susceptibility to Trichodina sp. was observed in L. macrocephalus, C. carpio and P. mesopotamicus compared to tambacu, B. cephalus, T. rendalli and 0. niloticus. It was not observed significant difference (P &gt; 0.05) in the seasonal variation of Trichodina sp. and P. pillulare infection of all species. A great number of P. pillulare without significant difference (P &gt; 0.05) was reported to L. macrocephalus, P. mesopotamicus and tambacu.
