Prospects of the application of minerals of natural origin in fish culture due to their physical-chemical properties and efficiency in animal breeding (a review)

Purpose.To describe the basic physical-chemical and biological properties of certain minerals of volcanic origin, which are deposited in Ukraine.To examine and make a comparative assessment of their chemical composition and biological properties including zeolite, bentonite and saponite. To summarize performance data on the effectiveness of their use in animal, poultry and fish feed as a feed additive. Findings. Groups of zeolites, saponins and bentonites among the minerals of volcanic origin, which are deposited on Ukrainian territory, have been examined. The chemical composition, and hence the properties of these minerals have significant differences. The scientific review of papers shows their wide application in industry, medicine and animal breeding. Zeolite component is presented by clinoptilolite which is suitable for animal feed because of the structure of the crystal lattice. Its structure and chemical composition is determined by sorbing and ion exchange properties. There is a positive effect of zeolite, bentonite and saponite on animals. Zeolites are used in pisciculture in order to increase fish productivity of fisheries and clean fishing reservoir water. The perspective of research efficiency of volcanic origin minerals in fish feeding before the sawning period was determined Practical value. Analysis and synthesis of scientific studies in various fields of animal breeding will help to determine the prospects and ways of the application of the minerals of volcanic origin (bentonite, zeolite and saponite) in pisciculture.
