Abstract
Ichthyofauna in the studied streams in the Pymvashor Geothermal Valley contains six species from six families; the basis of the fish assemblage is formed by three species such as European grayling Thymallus thymallus, common minnow Phoxinus phoxinus and stone loach Barbatula barbatula. Fish distribution patterns are expressed well in spatial and seasonal aspects. Fish inhabiting water bodies in the Pymvashor Geothermal Valley belong to two faunal complexes with prevalence of species of the boreal piedmont complex; three groups are distinguished in respect to the feeding habits, i.e. benthophagous, predatory, and euryphagous fishes. Species which lay eggs on rocky-pebbly substrates in late spring and early summer prevail. According to the economic status three fish species are non-commercial; common bullhead is listed in the regional Red Data Book of the Nenets Autonomous Okrug.中文翻译:
