Summary/Abstract: The obtained research results of the three-year study (2012–2014) of the bog stream zooplankton found in Shichengskii mire (Vologda Region, Russia) are presented. In total, 52 species were discovered (22 – Rotatoria, 18 – Cladocera, 12 – Copepoda). Phytophilic and acidophilic species were prevalent: the maximum richness of species was observed at the end of the summer season and at the beginning of the fall. The maximum level in the number of species was recorded in July–August of every year due to a strong increase in the growth of Cladocera. At the same time, cyclops were dominant in the coenosis during the most part of the vegetation season. The dominant complex was formed mainly by eurybiontic species. The average values of zooplankton abundance and biomass in the bog stream in focus were significantly higher when compared to small rivers of non-mire origin.
