The present study was performed to determine the effect of hCG, Ovaprim, and Ovarim on the efficiency of artificial reproduction in European perch (Perca fluviatilis), as well as the examination of the spermatological parameters of this fish. In the first treatment, hCG was used at 500 IU per kg body weight (BW) of broodstock. In second and third treatments, Ovaprim and Ovarim were used at 0.5 mL per kg BW. The control group was injected with physiological saline at 0.5 mL per kg BW. Eighteen female broodstocks with an average weight of approximately 78 g were used in each treatment. According to the results, the fastest latency time (415.6 degree-hour) was observed in the hCG treatment and showed a significant difference with other treatments. The highest ovulation rate (100%) was observed in hCG and Ovaprim treatments and showed significant differences with Ovarim and control groups. Results of this study showed that hCG is more suitable than Ovaprim and Ovarim for the induction of spawning and artificial reproduction of European perch. Due to the more favorable effects of hCG, it is recommended to use this hormone in spawning induction and artificial reproduction of European perch broodstock.
