Summary:
The changes in zooplankton of Hrazdanriver in the long profile, within the period May – October 2006 at 3 stations have been studied. There are 25 species of invertebrates, of which two species of rotifers, 13 of cladocerans and 10 of copepods. The highest species diversity of zooplankton was observed from river’s outletdown to the city Yerevan, the mouth area was characterized by poor species diversity of zooplankton, biomass uniformity as well as an increase in the proportion of invertebrates, producing food from the surface of the substrate.The main dominating factors of zooplankton have been determined.

Keywords: ecological groups, Hrazdan river, species composition, zooplankton
