Summary: The object for the research was an oar, grown in LLC WG "Mercury" with. Pultivtsi of Vinnytsia district. The task of this work was to investigate the evaluation of broodstock, preparation for factory reproduction, the dose of pituitary gland, the duration of incubation of eggs and larval yield depending on temperature conditions, as well as determining the efficiency of economic activity of the economy. Paddlefish (Latin Polyodon spathula) - a species of freshwater ray-finned fish of the family Paddlefish stur-geon. It lives mainly in the Mississippi River, as well as in a number of rivers flowing into the Gulf of Mexico. The only species of sturgeon that feeds on zoo, phytoplankton and detritus, swimming with its mouth constantly open and draining it with gill bristles. In the latitudes of Ukraine (Vinnytsia region - 48-50 °) with the sum of temperatures of 1.8-2.2 thousand degrees, reaching the IV completed stage of maturity of the gonads in the oarsman lasts for 10-11 years. On the basis of complex researches the prospects of cultivation of new for domestic aquaculture object of fish farming in pond farms of Ukraine are proved. For the first time in the country`s fish-breeding practice, the offspring of the oarsman was obtained from broodstock raised in ponds. New data on fish - biological characteristics of the oarsman relocated to the ponds of the forest-steppe zone have been obtained. The fishery substantiation is devel-oped and prospects of introduction of an oar-bearer in domestic aquaculture are defined. The practical significance of the obtained results. The production is offered recommendations for the repro-duction of oarsmen in ponds of Ukraine. An old-age repair herd of paddlefish has been formed, which can be used in the process of implementing a long-term program of fishery development of this non-traditional fish farm.
