INFLUENCE OF SALINITY ON DISTRIBUTION OF MACROPHITO- AND ZOO-BENTHOS POPULATIONS OF THE NORTHERN PART OF THE CASPIAN SEA

Abstract

The results of research done by CaspNIRKh on the development and spatial distribution of macrophyto-and zoobenthos in the northwestern part of the Caspian Sea are presented. Data on seasonal and long-term dynamics of biomass and species composition of phytocenosis together with other environmental factors such as salinity and a type of sediments show the state of benthic ecosystems in that part of the sea. Data obtained on the development of benthic communities reveal eutrophic areas for feeding commercially valuable fish species and estimate the carrying capacity of the sea (when introducing artificially reared juveniles).
