Abstract :
This study was conducted to determine the artificial breeding with application of optimum dosage of stimulatory Ovaprim hormones. Female treated with T1 (0.3), T2 (0.4), T3 (0.5), and T4(control) ml/kg/body weight. The result showed that stimulated with T3 (0.5) obtained better eggs quantity (25006) followed by T2 (0.4) (17,200), while the lowest quantity (8233) was in T1 (0.3), but T4(control) was failed. The spawning hours, fertilization and hatchability, was significantly affected by three doses (P ˂ 0.05). The hatchability hours was not significantly affected by hormone doses (P ˃ 0.05). The survival rate was significantly affected by hormone doses (P ˂ 0.05). The highest survival rates (53.67%) observed in T3 (0.5) followed by T2 (0.4) (42%) while the lowest (32.67%) in T1 (0.3).
