Journal Title: «Таврійський науковий вісник» - Year 2016, Vol 96, Issue
Abstract
The article presents the results of researches on the use of hormonal preparations of both natural and artificial origin, in order to stimulate maturation of sterlet breeders. Advantages of the use of natural glycerin extract of sturgeon pituitaries and Nerestin H5 synthetic preparation were experimentally proved. The first of the mentioned preparations is more effective at low water temperature and its extremes, while the other is used mainly during spawning temperatures stabilization. Negative results were obtained when using synthetic preparation Surfagon.
