【 摘 要 】

Human Chorionic Gonadotropin (hCG) hormone has roles in inducing maturation, ovulation and fish spawning. Ovaprim is a reproductive hormone product that can stimulate the ovulation process and fish spawning. HCG hormone in marineculture is widely used for spawning fish with doses at around 1000 IU and 2 times of injections. This research was aimed to determine the effect of the combination of hCG and ovaprim hormone on spawning and figure the best treatment in inducing the spawning process of silver pompano. The method used four treatments: hCG x hCG, hCG x ovaprim, ovaprim x hCG, and ovaprim x ovaprim with three replicates of fish spawning (1 pair of parent fish). The best result in accelerating spawning latency time is ovaprim x ovaprim treatment and best performance is hCG x ovaprim treatment.
