Life is like a reservoir into which a scientist who is completely devoted to his work plunges




The article is devoted to the description of the pages of the life and scientific activity of the outstanding Ukrainian scientist N. I. Zagubizhenko, who made a great contribution to the formation of the theoretical base on the enrichment of natural and artificial water bodies with fodder resources in the conditions of the Steppe zone of Ukraine. Being a student of the doctor of biological sciences, professor P. O. Zhuravel [1,2], who believed that the enrichment of the benthic fauna of the Steppe zone of Ukraine can be carried out by introducing animal organisms that are absent in these reservoirs, which are characterized by wide plasticity and high vitality [9,12,15], Nadezhda Ivanovna Zagubizhenko was engaged in the study of the reconstruction of the benthic fauna of the reservoirs of southeastern Ukraine. In connection with the instability of the fodder base of water bodies in the Steppe zone of Ukraine, the question of the introduction of representatives of the estuarine fauna, their habituation and inclusion in the food rations of a number of commercial fish was and remains relevant in the current period of time. According to the nature of nutrition, most acclimatizers are biofilters [9], for which there is a sufficient amount of food in the form of detritus, the remains of higher aquatic vegetation, in most reservoirs of the Steppe zone of Ukraine. The conduct and substantiation of these research works were of a positive nature and have a significant contribution to the scientific base, theory, and practice of enriching water bodies with fodder resources and preserving the environment. The quality of water at all times has been and is one of the main indicators of the standard of living, therefore, all developed societies make every effort to provide the population and economy with a sufficient amount of water of a quality that is adequate to the requirements of the consumer. Most of the water comes from natural sources – rivers, lakes, reservoirs, the water quality of which must not only be assessed, but also predicted. Two main components are responsible for the quality of water in nature – the catchment basin and the ecological system of the water body [6, p. 36]. Each of them is located in certain conditions of geography and climate, characteristic of the region under study, in our research – the Steppe zone of Ukraine.
