In accordance with the early years studies and the proceeding of last year materials taken in the vegetation period, can be concluded: • The qualitative structure of zooplankton of oligothrophic (Sioni) water reservoirs was not sharply changed for years. It was changing dynamically and consistently. • The qualitative structure of zooplankton of eutrophic (Kumisi) water reservoirs was changed sharply. • The qualitative structure (biomass mg/m3) of zooplankton of vegetation period the Kumisi water reservoirs was changed sharply compared to the Sioni water reservoir. From the above mentioned we can conclude that anthropogenic euthrophical processes in Kumisi water reservoir differs from the processes going on in Sioni water reservoir.
