| Title : | PARASITES OF THE RUFFE GYMNOCEPHALUS CERNUUS IN THE KAMА RESERVOIR |
| Abstract : | Ruffe (Gymnocephalus cernuus) is a fish harvested by recreational fisheries and does not have commercial significance in the Kama Reservoir and Votkinsk Reservoir (Perm Krai, Russia). Nevertheless, this species of fish is involved in food chains in ecosystem and plays role as a host of many species of parasites. Material for this study (n=103) was collected from October 2024 to March 2025 from three sites: opposite the village of Khokhlovka (58°13' N., 56°20' E), near Golovanovo microdistrict (58°09' N, 56°27' E) and at the Kama Hydroelectric Power Station (58°06' N, 56°20' E). Collection and laboratory processing of biological material were carried out according to standard ichthyological and parasitological methods. In total, 16 taxa of parasitic organisms were detected. One Protozoa is represented by Microsporidea, fifteen Metazoa from four classes: Acanthocephala - 1 (Acanthocephalus lucii), Nematoda – 2 (Contracaecum microcephalum, Anisakis sp.), Cestoda – 2 (Triaenophorus nodulosus, Proteocephalus sp.), Trematoda – 10 (Bunodera luciopercae, Podocotyle atherinae, Phyllodistomum folium, Sphaerostomum bramae, Apophallus muehlingi, Ichthyocotylurus platycephalus, I. variegatus, I. pileatus, Paracoenogonimus ovatus, Tylodelphys clavata). Most of the G. cernuus parasite fauna presents flukes at the stage of metacercaria. It is important that P. ovatus, A. muehlingi, and the larvae of anisakid nematodes pose a potential danger for humans and carnivores. |
