In May-October 2012 the seasonal dynamics of the population of dominant species of Ciliates were studied on the occurrence in water bodies and the samples the types in reservoirs of the central forest steppe (Kamyshlovsky glen, Nizhneirtyshskaya and UvalnayaBitiya oxbows) and the southern forest steppe (lake Ivanovskoe) from Omsk region. In the surveyed waters 9 species of ciliates relating to 8 genera were totally found: Colepshirtus, Dileptusanser, Loxodes rostrum, Colpodacucullus, Stylonychiamytilis, Vorticella convallaria, V. picta, Paramecium aurelia, Tetrahymenapyriformis. In all waterbodies the dominant share of the number of occurrence of species of ciliates is high and rarely less than 40%.Most of dominant species dominate by occurrence and abundance.All these species are considered as indicator species of allochthonous and of autochthonous water pollution and determine the α-β- mesosaprobic pollution zone.
