During the research, the branch's specialists took hydrobiological, hydrological, hydrochemical and bacteriological samples, and also carried out fishing for research and control purposes.
The extraction of aquatic biological resources was carried out using single-walled nets with a mesh size of 30-70 mm. Processing of ichthyological material was carried out in the field.
The obtained samples were transferred to the branch scientists for further processing in the laboratory. Based on the data obtained, the reserves of aquatic biological resources and their habitat were assessed, the values of the recommended extraction of aquatic biological resources were determined, and measures for their conservation were developed.
