The expedition group collected hydrobiological and ichthyological material at control observation points on the Donskaya Tsaritsa, Erik, Myshkova, Aksai Esaulovsky, and Aksai Kurmoyarsky rivers.
A total of 30 hydrobiological and 10 ichthyological samples were taken at five points. Hydrological (water temperature, transparency) and chemical parameters (hydrogen index, concentration of dissolved oxygen in natural water) were also measured.
The collected material will expand the array of data used in assessing the state of aquatic biological resources and their habitat.
