A parasitological investigation was made at 420 fishes from 10 species: Perca fluviatilis L., Gymnocephalus cernuus (L.), Gobio gobio (L.), Tinca tinca (L.), Leuciscus idus (L), Nomacheilus barbatulus (L.), Lota lota (L.), Leucaspisus delineatus (HECKELL 843), Blicca biorkna (L.) and Rhodeus sericeus amarus (BLOCH 1782). The fishes were caught over one year period (1995-1996) in the Mała Panew river drainage basin (South Poland). In examined fishes the following parasite species were found: Diplostomum spathaceum (RUDOLPHI 1819)-metacercaria; Tylodelphys podicipina KOZICKA et NIEWIADOMSKA, 1960 - metacercaria, Asymphyllodora tincae (MODER 1790); Bunodera luciopercae (MÜLLER 1776); Triaenophorus nodulosus (PALLAS 1781) - plerocercoid; Proteocephalus cernue (GMELIN 1790); Camallanus lacustris (ZOEGA 1776); Neoechinorhynchus rutili (MÜLLER 1780); Echinorhynchus borealis (LINSTOW 1901 ); Acanthocephalus lucii (MÜLLER 1776) and Pomphorhynchus laevis (MÜLLER 1776). One species of tapeworm: P. cernue appeared as a new in the parasitefauna of Poland.
