“…Life cycles are not known for P. brevicaecum, P. inecoli, P. lacustri and P. umblae , but there are some notes that cercariae of P. umblae develop in sphaeriid bivalves (Butorina et al . ). Life cycles characterized by cystocercous cercariae developing in sphaeriid bivalves have also been linked to species of Gorgodera Looss, 1899 and Gorgoderina Looss, 1902 (Sinitsin ; Rankin ; Goodchild ; Lees ).…”

“…A presumed life cycle of P. magnificum was described by Cribb (1987b), and it was suggested that cystocercous cercariae produced by sporocysts in the gills of a Pisidium species are larval stages of this species. Life cycles are not known for P. brevicaecum, P. inecoli, P. lacustri and P. umblae, but there are some notes that cercariae of P. umblae develop in sphaeriid bivalves (Butorina et al 2008). Life cycles characterized by cystocercous cercariae developing in sphaeriid bivalves have also been linked to species of Gorgodera Looss, 1899 and Gorgoderina Looss, 1902 (Sinitsin 1905;Rankin 1939;Goodchild 1948;Lees 1953).…”

Petkevi ci ut_ e, R., Stun z_ enas, V., Stanevi ci ut_ e, G., Zhokhov, A.E. (2015). European Phyllodistomum (Digenea, Gorgoderidae) and phylogenetic affinities of Cercaria duplicata based on rDNA and karyotypes. 44,[191][192][193][194][195][196][197][198][199][200][201][202] Genetic markers of some European Gorgoderidae species, including potential adults of Cercaria duplicata, were obtained and used to clarify phylogenetic affinities within the genus Phyllodistomum and to verify conflicting data existing on their life cycles. Molecular data and karyotype, 2n = 18, provide further support for ascription of C. duplicata to the Gorgoderinae. Sequences of C. duplicata form a robustly supported major clade, phylogenetically distinct from other known gorgoderid species in both ITS2-and 28S-based phylogenetic trees. The molecular data revealed no match between C. duplicata and any species of Phyllodistomum, including adults found in the experimental studies. One of them, P. elongatum, showed no differences from type species P. folium. Other, P. angulatum, forms a robustly supported clade, which is closely related to P. macrocotyle clade in all phylogenetic trees. This study supports the concept that only P. macrocotyle is a parasite of Dreissena polymorpha among the phyllodistomes and life cycle described for the type species P. folium by Sinitsin (1905) can apparently be discounted. Previously reported low host specificity of P. folium was justified. Adults of P. folium were detected in eight teleost species from five families and four orders. Cystocercous cercariae of P. folium were recorded in sphaeriid bivalves of the genus Sphaerium and Pisidium. According to our molecular data, P. simile, parasite of bullhead, must be regarded as synonym of P. folium. Phyllodistomum umblae is most closely related to P. folium in the all phylogenetic analyses. Molecular phylogenies support a presumption that Phyllodistomum species with cystocercous cercariae developing in sphaeriid bivalves should be regarded as Phyllodistomum sensu stricto. The results reveal a clear need for reconsideration of the knowledge on gorgoderid life cycles based on experimental studies and re-evaluation of the validity of some nominal Phyllodistomum species.

“…Therefore, in different countries, research has been conducted for a long time, not only for fish, but also for their parasites in Protected Areas. Some of the investigations concerned the parasite communities and species composition in different fish species (Mudry & Anderson, 1977;Boomker, 1994;Murcia et al, 2006;Morozińska-Gogol, 2007, 2009Butorina et al, 2008;Shukerova & Kirin, 2008;Moravec & Bakenhaster, 2010;Sandlund et al, 2010;Shukerova et al, 2010Shukerova et al, , 2017Sokolov & Gordeev, 2014;Chunchukova et al, 2016;Chunchukova & Kirin, 2018;Rubtsova & Kutsokon, 2018;Utevsky et al, 2018). Other studies devoted to different systematic groups include data on fish parasites in Protected Areas (Sasal et al, 2004;Galli et al, 2007;Kirjušina & Vismanis, 2007;Székely et al, 2009;Wood et al, 2013;Halajian et al, 2018;Hoogendoorn et al, 2020).…”

Freshwater ecosystems of Mongolia belong to the three major Central Asian drainage systems: Arctic drainage, Amur River drainage, and Central Asian Internal drainage. The Great Lakes Depression takes considerable part of the latter. One of the few fish species living there, Oreoleuciscus potanini, is the most common and widespread endemic species in the Central Asian region. Parasitological surveys on O. potanini from the Great Lakes Depression have not occurred regularly in recent years. Consequently, this study was conducted to explore the species diversity of helminth parasites in O. potanini in the three lakes of Khar Us Nuur National Park. In total, 52 O. potanini specimens were collected from the lakes Khar, Khar Us and Durgen and sampled in August 2012. In addition to the parasites, the age and diet spectrum of the fish species were studied. The fish were examined for infection with ecto-and endo-macroparasites. The species composition of Diplostomum spp. metacercariae from the eyes of fish was investigated using a molecular approach. In the lakes Khar and Khar Us the fish age ranged from four to 32 years old and from eight to 35 years old, respectively. Fish of four age groups (9, 10, 11 and 14 years old) were in Lake Durgen. Algae and various insects, including Chironomida larvae were the main food of the O. potanini in all three lakes. When the diet was investigated we found that in Lake Durgen Cladocera crustaceans were the significant component in the fish diet, and no fish was found in the O. potanini diet there. During the study 26 parasites species were identified from the three lakes. The total fauna is represented by four phyla, including Acanthocephala (one species), Annelida (one species), Nematoda (four species), Platyhelminthes (20 species). The last group was the most numerous and diverse, including three species of Cestoda, six species of Monogenea and 11 species of Trematoda. Five species of parasites were specific to O. potanini only (monogeneans Gyrodactylus mongolicus, G. oreoleucisci, G. pewsowi, nematodes Philometra oreoleucisci and Rhabdochona humili). The other helminthes exhibited a low host-specificity, infecting a wide range of fishes in the Holarctic. The larvae of endohelminthes predominate in the parasite fauna. The majority of these parasites enter the fish via various invertebrate species during O. potanini's feeding. Our study provided novel data on the species diversity of Diplostomum spp. metacercaria in O. potanini's eyes. They were represented by three species: Diplostomum spathaceum, D. pseudospathaceum and Diplostomum sp. LIN2. The species richness and diversity of parasites were much higher for O. potanini from the lakes Khar and Khar Us (26 species), than that for O. potanini of Lake Durgen (15 species). The possible reason for the absence of some parasites in Lake Durgan is an increased water salinity. It is likely that, despite the potential for the fish to exist under conditions of an elevated salinity, parasites (or their invertebrate hosts) are not adapted to i...

“…Repeated investigations of the parasitofauna of the Kronotsky fishes reliably recorded 21 species of parasites of different taxa (Zschokke & Heitz, 1914;Kurenkov, 1977;Butorina et al, 1980Butorina et al, , 2008Butorina, 2003;Atrashkevich et al, 2005), but no monogeneans were found. At the same time representatives of this group of ectoparasitic flatworms are regularly found on salmonid fish from other water bodies of the Kamchatka Peninsula (Konovalov, 1971;Pugachev, 1983;Butorina et al, 2011;Busarova, 2012;etc).…”
