A total of 246 perch fry, 20 to 106 d old from 3 different reservoir subpopulations (epipelagic, EPF; bathypelagic, BPF; littoral, LPF)were examined for parasites. 6 species of endoparasites were found: Camallanus lacustris was the most common, followed by Proteocephalus percae, Bothriocephalus claviceps, Glanitaenia osculata and Acanthocephalus lucii. All worms were juvenile or immature and were recovered from the intestinal lumen, with the exception of plerocercoids of Triaenophorus nodulosus, which were found in the body cavity or already encysted in the liver. A marked difference was found in infection rates in the 3 spatially segregated subpopulations of perch fry. Parasites were found almost exclusively in LPF, which were heavily infected (prevalence 30%) compared with the other studied subpopulations. Two species (C.lacustris and T.nodulosus) were found in 1 fish each (prevalence 3%) in BPF, whereas EPF were uninfected.
