Destruction of the Ichthiofauna of the Southern Buh

Abstract

he work is dedicated to solving the environmental problems of the Southern Buh River, which arose as a result of the construction and operation of hydroelectric power plants and the search for ways to restore and preserve the lost ichthyofauna. It has been established that decades of economic exploitation of the water resources of the Southern Buh basin have had a devastating impact on the biodiversity of ichthyofauna. Many valuable species have been destroyed. The beginning of the degradation of the Southern Bug was the massive construction of hydroelectric power plants, which turned out to be a grandiose static-destructive pollution. The Southern Buh turned into a cascade of stagnant reservoirs, which completely changed and worsened the conditions for the existence of ichthyofauna species and led to their further disappearance. The construction of hydroelectric power plants had a strong structural and operational impact on the river ecosystem of the Southern Buh and led to the violation of fundamental ecological laws: the law of the minimum of Y. Liebig , according to which the relative effect of a single environmental factor will be the stronger, the more this factor, in comparison with other environmental factors, will approach its quantitative minimum; the law of tolerance of Shelford , according to which the presence or prosperity of a population of any organisms in a given location depends on a complex of environmental factors, to each of which there is a certain range of tolerance (endurance) in the organism; from the law of feedback of human - biosphere interaction , first formulated by P. Dansereau, according to which any change in the natural environment caused by human economic activity "returns" and has undesirable consequences that affect the economy, social life and health of people. The processes of destruction of the Southern Buh, caused by enormous overregulation and significant pollution, continue, which negatively affects its inhabitants, in particular, new representatives of the ichthyofauna are being added to the category of endangered and missing. Proposed that will help stop the process of final destruction of the Southern Buh, restore its water resources, and recreate the lost ichthyofauna.
