Abstract
Purpose. To investigate the effect of different types of fertilizers on the formation of hydrochemical regime in rearing ponds. Methodology. For the study, we used generally accepted hydrochemistry methods. For the overall (total) chemical analysis, water samples were taken two times during the season (at the beginning and at the end of the growing season), a short chemical analysis of water was carried out twice a month. Findings. The article presents the research results of hydrochemical regime in rearing ponds of the State Enterprise "Nivkа" when applying different types of fertilizers. It was found that hydrochemical regime in experimental rearing ponds was formed under the effect of water supply source and measures aimed at improving the development of the natural food supply (application of cattle manure and microfertilizer "Rostok" Macro). No significant difference was observed between hydrochemical parameters when applying different types of fertilizers. The dynamics of seasonal changes in the basic chemical indicators in both experimental ponds was similar, however, the pond fertilized with manure was characterized by higher values of permanganate oxidation, ammonium and nitrite nitrogen during the entire culture season. In general, the hydrochemical regime in rearing ponds was satisfactory and suitable for the cultivation of carp seeds when applying either cattle manure or microfertilizer "Rostok" Macro. Originality. The peculiarities of the formation of the hydrochemical regime of rearing ponds when applying cattle manure and "Rostock" Macro fertilizer have been investigated. Practical value. The obtained data can be used to develop practical recommendations for the optimization of growing conditions of fish seeds when applying of various types of fertilizers, increasing the efficiency of aquatic ecosystems management and their bioproductivity.
