Induced spawning of pearl oysters serves a dual purpose in pearl culture. Besides providing the gametes for the hatchery production of seed, it conditions the oyster for nucleus insertion for the production of cultured pearls. Experiments were conducted on induction of spawning in Pinctada fucata using hydrogen peroxide, tris buffer, sodium hydroxide and combinations of hydrogen peroxide+tris/NaOH. In other experiments ammonium hydroxide (N/10) was injected into the adductor muscle or foot of the oyster. Thermal stimulation was also attempted.
