“…The component community of parasites of Coregonus lavaretus in Lake Kamennoye is represented by species typical for oligotrophic water bodies (Anikieva et al, 1983). The helminths found in our study are common across the range of C. lavaretus.…”

“…Like their hosts, these helminths are adapted to the life in oligotrophic water bodies with low temperatures and limited diversi-ty of plankton and benthos. The nematodes R. acus and C. lacustris and the metacercariae of trematodes from the genera Diplostomum and Tylodelphys occur in various hosts from various taxonomic and ecological groups, and are eurythermal and eurybiontic (Anikieva et al, 1983;Pugachev, 2003;Barskaya et al, 2008;Anikieva & Ieshko, 2019).…”

“…Intermediate hosts of P. longicollis and T. crassus are copepod crustaceans such as Tritia Risso, 1826, Mesocyclops G.O. Sars, 1914, and Eudiaptomus Kiefer, 1932(Kuperman, 1974Anikieva et al, 1983), while the life cycle of C. lacustris involves crustaceans from the order Cyclopoida (Moravec, 1994). Infection of C. lavaretus with R. acus is apparently associated with benthos feeding, since the paratenic hosts of this nematode are molluscs, oligochaetes, amphipods, water lice and insect larvae developing in water (Moravec, 1994).…”

Macroecological models are useful for assessing trends in variability for developing monitoring strategies of successional changes and anthropogenic transformation of aquatic ecosystems. Modelling of the relationships of the generalised population indices also makes possible to reveal qualitative differences in the structure of parasite component communities. We analysed helminth communities of Coregonus lavaretus from a natural water body, Lake Kamennoye (Kostomuksha State Nature Reserve, Russia). The component community of metazoan parasites of C. lavaretus was represented by nine helminth species. Infection with cestodes (two species), nematodes (three species), and trematodes (one species) reflects the presence of zooplankton, aquatic insects and molluscs in the diet of fish, while infection with trematode larvae (three species) occurs by percutaneous penetration. The complete ITS1-5.8S-ITS2 cluster of the rRNA gene was sequenced in order to identify trematode larvae. Metacercariae of Diplostomum sp. LIN 5 were the most abundant among them. Using populational approaches, we described the species richness and the diversity of infra- and component communities of the parasites. We also described the species composition and the structure of the component community, the distribution and the accumulation rate of species richness, and the relationships between the infection intensity and the prevalence. Five species (Diplostomum sp. LIN5, Tylodelphys immer, Crepidostomum farionis, Proteocephalus longicollis, and Raphidascaris acus) were considered as the core species of the component community, while other helminths were considered as satellite species. We conclude that infra-communities play a key role in the formation of species richness, structure and abundance of the parasitic component community of C. lavaretus. Infra-communities in younger age groups of C. lavaretus are characterised by the paucity and a relatively high diversity of the species composition of parasites, which is probably a consequence of their diverse diet. In older fish, the species richness of infra-communities increases but the species diversity of the parasites declines, indicating a pronounced dietary specialisation. An analysis of species richness and population characteristics indicates that in Lake Kamennoye, the parasite communities of C. lavaretus are fairly stable, which reflects the stability of the entire lake ecosystem.

“…In Lake Norsjø, three-spined sticklebacks and European smelt are present (Jensen 1954), which are both intermediate hosts for Dibothriocephalus spp. (Andersen et al 1986;Andersen & Valtonen 1992;Anikieva & Ieshko 2017). D. ditremus also exhibited a higher abundance in male charr, with no apparent relationship between sex and any other variable that could explain the higher occurrence of D. ditremus in males.…”

Factors determining parasite abundance in European perch, Perca fluviatilis, European whitefish, Coregonus lavaretus, and Arctic charr, Salvelinus alpinus, in an oligotrophic lake, southern Norway

Time and spatial variations in macroparasite status were investigated in European perch, Perca fluviatilis, European whitefish, Coregonus lavaretus, and Arctic charr, Salvelinus alpinus in Lake Norsjø (Southern Norway), based on gillnet fishing in three locations in the spring, summer, and fall 2018. In addition, length, weigth, age, sex, δ13C, and δ15N were determined. Parasite abundance was modelled using negative binomial generalized linear models in relation to fish metrics, season, and sampling location. The most prevalent parasite species were determined by the diet and habitat of the host. European perch was mainly infected by acanthocephalans, European whitefish mainly infected by acanthocephalans and cestodes, and Arctic charr mainly infected by cestodes. The most prevalent parasites in European perch are transmitted by benthic animals. Parasites in European whitefish are transmitted by both benthic animals and copepods, while the most prevalent parasites in Arctic charr are copepod transmitted. This corresponds well with the δ13C signatures in the three species, indicating that European perch primarily fed in the littoral zone (δ13C: -24.9 ± 2.5 ‰), Arctic charr in the pelagic and profundal zone (δ13C: -29.4 ± 1.1 ‰), while European whitefish both fed in the littoral and pelagic zone (δ13C: -28.3 ± 2.3 ‰) of Lake Norsjø. Individual abundances of parasites depended on host age, length, sex, δ15N, and season. Positive correlations between parasite abundance and host age, length, or trophic level measured as δ15N were most common, and occurred in all three host species. Many parasites accumulate with age, and larger hosts provide more diverse habitats for parasites.
