This study was conducted to compare the effectiveness of Ovaprim and Ovapass hormones to induce spawning in Schizothorax zarudnyi. The female (n=48; 1535.12±180.09 g) and male broodstocks (n=53; 752.00±48.30 g) were randomLy allocated in 4 experimental groups including T1: females which received 0.2, 0.5 and 0.5 mL /kg body weight (BW) Ovaprim with 24-h time intervals, T2: females which treated with 0.5 and 0.5 mL /kg BW Ovapass with 12-h time intervals, T3: females were injected with 0.2, 0.5 and 0.5 mL /kg BW Ovapass with 24-h time intervals, and T4: females were injected with a combination of Ovaprim (0.2 mL/kg) and Ovapass (0.5 and 0.5 mL/kg BW) with 24-h time intervals. The amount of injection in the first stage was 10%, the second stage was 90%, and the male fish were simultaneously injected with the second stage of the females at 0.3 mL/kg. The results showed that the highest rate of fertilization was detected in treatments 2 and 4 (93.33% and 92.33%, respectively), which had a significant difference with other groups (p<0.05). No significant differences were observed between the treatments in the indices of relative and working fecundity and dry egg diameter (p>0.05). The lowest and highest latency period was observed in treatments 2 (27.33± 0.66 h) and 1 (36.20±3.77 h), respectively (p<0.05). The results of this study clearly suggested that the Iranian Ovapass hormone is highly effective for S. zarudnyi reproduction and might be successfully replace with Ovaprim.
