Abstract
Purpose. Examine and analyze the current state of storage fingerlings acipenseriformes cultivation, including sturgeon and paddlefish, in terms of industrial-experimental Dnieper sturgeon fish-growing factory located in the southern Ukraine. Methodology. The problems were solved by the conventional methods in hydrochemistry, hydrobiology and fish farming. The results were processed using statistical methods of the data processing and analysis which suggest it reliable. Findigs. The research has established that physical and chemical parameters of water in farms' ponds answered the operating pond fishery regulations. The existing level of natural forage base elements can be considered satisfacting for the growing storage material. The best development of zooplankton in the application of polyculture acipenseriformes should be noted. The monoculture benefit was observed in the most fisheries indicators for certain types. Sturgeon fish productivity advantage in terms of polyculture is the evidence of positive mutual influences among the reservoir consumers of different trophic levels. In terms of polyculture the significant benefit of total fish productivity indicator was observed. It clearly points to the prospects of the measure in terms of substantial efficiency of pond areas for growing storage fingerlings. Results of acipenseriformes growing in mono- and polyculture clearly favor the polyculture, which could be used in breeding practice. Scientific Originality. In specific conditions of the southern Ukraine the influence of environmental and technological conditions for growing storage fingerlings acipenseriformes fish (sturgeon and paddlefish) was investigated for the first time. In terms of mono- and polyculture cultivation storage acipenseriformes fish material was firstly explored. Practical Value. The results of cultivation can be used in breeding practice as the norm of the environmental situation evaluation in the ponds. Growing storage fingerlings acipenseriformes in polyculture allows better usage of the natural food base, improving productivity and efficient usage of farms' water growing areas.
