Summary: Phenological phases or seasons of the zooplankton were determined by the method of discriminatory analysis in Petrozavodsk bay of Lake Onega. On the basis of the data on the zooplankton abundance and the biomass of the main taxonomic groups, received from 1988 to 2010, four seasonal conditions of the community, their timing and duration were determined. On an average, summer period for zooplankton in Petrozavodskaya bay lasts 66 days, it is 24 days longer than in the central area of the lake. The relationship between zooplankton phenology and hydrodynamic and thermal conditions are considered
