The aim of the current work was to compare the effectiveness of Ovopel and Ovaprim separately and combined and LH-RH-a in the controlled reproduction of ide, Leuciscus idus (L.). The impact of the chosen hormonal preparations on ovulation, spermiation, and the quality of the gametes obtained was determined. The results confirmed the necessity of stimulating ovulation with hormone complexes and dopamine antagonists. The high effectiveness of both Ovopel and Ovaprim for ovulation stimulation in female ide was also confirmed. The greatest degree of ovulation synchronization was obtained after the application of Ovopel (eggs obtained after 36 h); however, the best results of controlled reproduction were obtained after using Ovaprim and a combination of Ovopel and Ovaprim (82 and 85% embryo survival, respectively). The highest percentage of motile sperm was noted in semen taken from males stimulated with Ovaprim (80%) and LH-RH-a (81%).
