 abstract={Changes in species structure and changes in numbers and biomass of Rotatoria and crustacea in lakes varying as to trophic state, morphometry and degree of pollution have been analysed. On the basis of changes in the dominance of particular species in the biomass of communities ecological groups of organisms were distinguished among Rotatoria and Crustacea, characteristic of lakes of a low and high trophic state. The numbers increased, and to a smaller extent the biomass of Rotatoria as the trophic state increased, but such relation was not observed in the case of Crustacea.},
