Specialists of the Zavolzhsky Territorial Administration of the Ministry of Ecology of the Republic of Tatarstan, together with representatives of the RT State Committee for Bioresources, aerated an unnamed lake near the village of Adav-Tulumbaevo of the Buinsky district as part of the action "Fish will live! (Balyk – Bulsyn!)". Timely implementation of such preventive measures provides an additional amount of oxygen in the water and allows one to preserve fish stocks in reservoirs.
