This study investigates the presence of metazoan parasites on tench (Tinca tinca L.) in Lake Uluabat, Turkey. Data were obtained from on-site surveys carried out between April 1998 and January 2000. Six parasite species were identified: Dactylogyrus macracanthus Wegener, 1909; Asymphlodora tincae (Mooder, 1790); Acanthocephalus lucii (Müller, 1787); Ergasilus sieboldi Nordmann, 1832; Argulus foliaceus Linne, 1758; and Piscicola geometra Linne, 1758. Of these species, three were found on gills of the tench: D. macracanthus (prevalence 15.0%; mean intensity 12.10 ±7.39), A. foliaceus (4.2%; 2.67 ±1.51), E. sieboldi (32.1%; 53.88 ±33.96); P. geometra was found on the skin (1.4%; 1.00 ± 0.00); A. lucii in the intestine (2.8%; 1.75 ± 0.58) and A. tincae in the gut and intestine of the host fish specimens (26.4%; 87.70 ± 108.31). In addition, the density of parasite species was determined according to season as well as according to size of the host fish.
