This paper offers a summary of the data on parasites of European smelt based on own collections and materials published in journal reviews, scientific papers, conference proceedings and theses. The system of parasitic organisms published in Catalogues of parasites of freshwater fishes of North Asia [Pugachev, 2001[Pugachev, -2004 is used, taking into account new studies on the systematics of infusorians and trematodes. Other groups of parasites are considered within the frameworks of widely used classifications. The species structure of European smelt and its ecological forms follow the classification by L. Berg [1948] and Yu. Reshetnikov [Atlas …, 2003]. Altogether 65 species/taxa of parasites have been recorded from the distribution range of European smelt (Conoidasida -1, Haplophasea -2, Ichthiosporea -1, Myxosporidia -1, Phyllopharyngea -1, Oligohymenophorea -3, Monogenea -1, Cestoda -9, Trematoda -11, Nematoda -19, Palaeacanthocephala -7, Hirudinea -1, Bivalvia -1, Crustacea -7). Each parasite species is briefly described; the species occurrence in different smelt ecoforms, sources for species records (provenance and author) are stated. For higher taxa, we analyzed the taxonomic diversity of smelt parasites, their zoogeographic zoning and distribution, as well as specificity, distinctive morphological, biological and ecological traits. л. в. аникиева, е. п. иешко. анноТированный списоК видов паразиТов европейсКой КорЮшКи OSMERUS EPERLANUS (L.)Обобщены данные по паразитам европейской корюшки, основанные на собствен-ных и литературных материалах, опубликованных в журнальных обзорах, научных публикациях, материалах конференций и диссертациях. В работе использована система паразитических организмов, опубликованная в Каталогах паразитов пре-сноводных рыб Северной Азии [Пугачев, 2001-2004], учтены новые исследования в области систематики инфузорий и трематод. Остальные группы паразитов рас-смотрены в рамках широко применяемых классификаций. Структура вида евро-пейской корюшки и ее экологические формы приняты по классификации Л. С. Бер-га [1948] и Ю. С.

В общей сложности в ареале ев-ропейской корюшки зарегистрировано 65 видов/таксонов паразитов (Conoidasida -1, Haplophasea -2, Ichthiosporea -1, Myxosporidia -1, Phyllopharyngea -1, Oligohymenophorea -3, Monogenea -1, Cestoda -9, Trematoda -11, Nematoda -19, Palaeacanthocephala -7, Hirudinea -1, Bivalvia -1, Crustacea -7).

Институт биологии Карельского научного центра РАН Приведены сведения о гельминтах чаек, отловленных на водоемах Северной Карелии. Фауна паразитов представлена 8 видами-Trematoda (5 видов), Nematoda (2 вида), Cestoda (1 вид). Впервые на территории России зарегистрирован вид Gigantobilharzia mazuriana Khalifa 1974.

A comparative analysis was carried out investigating the parasite faunas of coregonids (humpback whitefish, peled, least cisco, and tugun) from the Lower Ob Ural tributaries (Rivers Synya, Voykar, Severnaya Sos'va, Sob, Shchuch'ya) and from the Khatanga River. Surveys revealed 48 parasite species, most with a complex life cycle (29 helminth species and 3 myxosporidian species whose development involves benthic organisms). Semianadromous whitefish spawning in Lower Ob tributaries were shown to have a poorer species composition of parasites (13-16 species) compared to land-locked whitefish from the Khatanga (23 species). The parasite fauna of semi-anadromous peled from the Lower Ob had the most diverse species composition among the rest of coregonids, with relatively high similarity between the rivers Voykar and Synya, while that of the S. Sos'va River stood apart. Resident ecotypes of peled from the rivers Shchuch'ya and Khatanga were similar in the species composition of their parasites in spite of the substantially different geographical locations of the catchments. Least cisco within the Lower Ob basin (Rivers Voykar and Sob) featured a high similarity of the parasite species composition, which was, however, very different from that in least cisco from the Khatanga. Some freshwater parasites (infusorians, monogeneans, trematodes and leeches) apparently get lost in the brackish waters of Khatangsky Bay, while the crustacean Coregonicola orientalis is introduced into the river during the spawning run. The parasite fauna of tugun was the richest in the Khatanga (17 species), relatively poor in the Sob (5) and Shchuch'ya (6 species), and generally reflected the features of the fish ecology in each specific river.
