Abstract: The key to artificial large - scale breeding is to induce the maturation of parent clams in order to obtain high - quality oosperms. The parent Paphia undulata has low synchronous rates in sexual maturation and they are usually not concentrated in spawning time. In this study， the parent clams of Paphia undulata were temporary rearing for 5 days，10 days，15 days，20 days in indoor cement pools and outdoor ponds separately，then air-dried or stimulated by flowing water in order to induce spawning，their gonadal developments and induced spawning effects in the different measures and durations were compared. The results showed that the situation of Paphia undulata‘’s gonadal developments was better and the death rate was lower when they were cultured in outdoor ponds than indoor cement pools，moreover，both the effects of gonadal development and induced spawning of the parent clams were best when cultured for 10 days in outdoor ponds.
