Moscow specialists of the Mosvodostok enterprise initiated a series of measures for aeration of urban water bodies. In other words, more than two hundred lakes, ponds and hands will be subjected to oxygen saturation.According to experts, this will have a beneficial effect on the aquatic ecosystem and help fish and other inhabitants of water bodies to successfully winter.

“Oxygenation is carried out only in those reservoirs that are covered with a thick layer of ice of 12 centimeters or more,” experts say. “We aerate the water so that fish, crayfish, shrimp and shellfish, as well as the aquatic flora, do not die due to oxygen deficiency!”

To understand how much oxygen a particular reservoir requires, experts in matters of aeration take water for a sample, determining its temperature, acidity and saturation with various gases and substances. After that, holes are drilled in ice at the rate of two holes per hectare and the holes are covered with special wooden trays so that the holes do not freeze and oxygen enters the water. This year, such holes appeared on a pond in Izmaylovsky Park, as well as on the Patriarch's Ponds and Novodevichy.
