The observed cases of infection in fish featured a high prevalence, when almost all of the fish were infected. However, if an outbreak of the monogenean infection is observed in spring, the intensity of the infection may be low, and when the infection occurs in the ice-covered period (late autumn - winter), the number of parasites on the fins of a single fish may exceed 3000 specimens. Molecular identification of the parasite demonstrated that the infecting clone was identical with rainbow trout specific strain of Gyrodactylus salaris RBT widely spread in Northern Europe, but a small proportion of the parasites were the hybrid clone Gyrodactylus pomeraniae x G. lavareti. Morphological variations of hooks and other opisthaptor parts in the monogenean Gyrodactylus depending on the intensity of infection in rainbow trout were demonstrated.<\/jats:p>","DOI":"10.1515\/ap-2016-0020","type":"journal-article","created":{"date-parts":[[2016,1,11]],"date-time":"2016-01-11T17:15:00Z","timestamp":1452532500000},"source":"Crossref","is-referenced-by-count":6,"title":["Occurrence and morphogenetic characteristics of Gyrodactylus (Monogenea: Gyrodactylidae) from a rainbow trout farm (Lake Ladoga, Russia)"],"prefix":"10.1007","volume":"61","author":[{"given":"Evgeny","family":"Ieshko","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia","family":"Barskaya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksey","family":"Parshukov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaakko","family":"Lumme","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleg","family":"Khlunov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","reference":[{"key":"ref81","doi-asserted-by":"publisher","first-page":"233","DOI":"10.1111\/j.1095-8649.1986.tb04941.x","article-title":"Infestations of Atlantic salmon ( Salmo salar ) by Gyrodactylus salaris in Norwegian rivers of Fish","volume":"29","author":"Johnsen","year":"1986","journal-title":"Journal Biology"},{"key":"ref111","first-page":"76","article-title":"Occurrence of Gyrodactylus ( Monogenea ) on salmon and rainbow trout in fish farms in northern Finland Bulletin of the Scandinavian Society for","volume":"5","author":"Koski","year":"1995","journal-title":"Parasitology"},{"key":"ref141","first-page":"53","article-title":"Description of three new European cryptic species of Gyrodactylus Nordmann supported by nuclear and mitochondrial phylogenetic characterization","author":"Kuusela","year":"2008","journal-title":"Acta Parasitologica"},{"key":"ref21","doi-asserted-by":"publisher","first-page":"575","DOI":"10.2307\/3284227","article-title":"Parasitology meets ecology on its own terms : revisited","volume":"83","author":"Bush","year":"1997","journal-title":"Journal of Parasitology"},{"key":"ref131","doi-asserted-by":"publisher","first-page":"5234","DOI":"10.1111\/j.1365-294X.2007.03562.x","article-title":"Hybrid origin of Baltic salmon - specific parasite Gyrodactylus salaris : a model for speciation by host switch for hemiclonal organisms","volume":"16","author":"Kuusela","year":"2007","journal-title":"Molecular Ecology"},{"key":"ref61","first-page":"60","article-title":"A new Gyrodactylus strain on brown trout ( Salmo trutta ) in Janisjarvi Russian Karelia and a literature revision of salmonid parasites of the genus Gyrodactylus in North - Western Russia and adjacent areas","author":"Ieshko","year":"2015","journal-title":"Acta Parasitologica"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"69","DOI":"10.1016\/0165-7836(93)90008-U","article-title":"Comparative susceptibility of native Scottish and Norwegian stocks of Atlantic salmon salar to Gyrodactylus salaris Malmberg : laboratory experiments","volume":"17","author":"Bakke","year":"1993","journal-title":"Fisheries Research"},{"key":"ref121","doi-asserted-by":"crossref","first-page":"21","DOI":"10.5735\/086.046.0103","article-title":"Clonal structure of salmon parasite Gyrodactylus salaris on a coevolutionary gradient on Fennoscandian salmon ( Salmo salar )","volume":"46","author":"Kuusela","year":"2009","journal-title":"Annales Zoologici Fennici"},{"key":"ref171","doi-asserted-by":"publisher","first-page":"143","DOI":"10.1111\/j.2006.0018-0661.0195","article-title":"Escape from an evolutionary dead - end : a triploid clone of Gyrodactylus salaris is able to revert to sex and switch host ( Platyhelminthes","author":"Zi\u0119tara","year":"2006","journal-title":"Hereditas"}],"container-title":["Acta Parasitologica"],"original-title":[],"link":[{"URL":"https:\/\/www.degruyter.com\/view\/j\/ap.2016.61.issue-1\/ap-2016-0020\/ap-2016-0020.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T16:40:37Z","timestamp":1607964037000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.degruyter.com\/view\/j\/ap.2016.61.issue-1\/ap-2016-0020\/ap-2016-0020.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,1]]},"references-count":9,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.1515\/ap-2016-0020","relation":{},"ISSN":["1896-1851","1230-2821"],"issn-type":[{"value":"1896-1851","type":"electronic"},{"value":"1230-2821","type":"print"}],"subject":[],"published":{"date-parts":[[2016,1,1]]}}}
