Parasite fauna of ide, Leuciscus idus (L.) in Lake Dąbie, Poland

Abstract

The previous surveys on parasites of ide, Leuciscus idus (L.), were carried out in Poland from 1960 to 1987, but there have been no available data on the parasites of this fish from the waters of the western Poland. The parasite fauna of ide from the Dabie Lake (western Poland) and a comparison of the results with the relevant data on the subject published by other authors, are presented. Standard parasitological procedures were applied to 110 individuals of ide caught within 2000-2003. All fish examined were infected with parasites. The parasites recovered, represented 32 species and 11 higher taxa: Oligohymenophorea, Myxosporea, Monogenea, Digenea, Nematoda, Palaeacanthocephala, Euacanthocephala, Hirudinea, Copepoda, Branchiura, and Bivalvia. A total of 15 parasite species represented new host records for ide in Poland (Dermocystidium sp., Myxidium pfeifferi, Zschokella nova, Myxobolus carassii, M. muelleri, Henneguya cutanea, Tripartiella copisa, Paradiplozoon bliccae, Gyrodactylus prostae, Anisakis simplex, Streptocara crassicauda, Philometra rischta, Argulus foliaceus, Piscicola geometra, Hemiclepsis marginata). The highest values of prevalence were recorded for: Ergasilus sieboldi, Diplostomum spp., Tylodephys clavata, and Paracoenogonimus ovatus. Infection parameters of the presently surveyed ide were distinctly different from those previously described. It is possible that populations of some parasites grew within the past 20 years
