Research into the hydroecosystem of Lake Ilmen continues

On August 7, as part of joint work of the branches of the North-West region, specialists from the St. Petersburg and Novgorod branches of the All-Russian Research Institute of Fisheries and Oceanography (VNIRO) conducted summer comprehensive field studies on Lake Ilmen in order to implement state monitoring of aquatic biological resources and their habitat in inland waters.
 
During the cruises, hydrobiological, microbiological and hydrochemical samples were collected to determine the composition and distribution of food aquatic organisms - zooplankton, zoobenthos, the level of development and productivity of phytoplankton, the quality of the environment and an assessment of chemical pollution of waters, and primary hydrological data were collected characterizing the habitat of aquatic biological resources at 10 monitoring stations in the lake's water area.
 
Additionally, in order to study the overgrown complex of hydrobionts, studies of the littoral areas of the lake were conducted: a description of plant communities was conducted, samples of phytoplankton, zooplankton, microbial communities, zooperiphyton and macrozoobenthos were collected.
 
Specialists from the branches began office processing of field materials, based on the results of which recommendations will be prepared for the effective use of the fishery reservoir.
