【摘要】 在人工育苗的过程中,对亲贝进行促熟培育获得高质量受精卵是开展规模化育苗的关键。波纹巴非蛤(Paphia undulata)亲贝存在性成熟同步率低、产卵不集中的问题,研究对波纹巴非蛤亲贝分别进行室内水泥池和室外土池人工暂养促熟培育,经5、10、15、20 d的暂养促熟培育后,采用阴干、流水刺激的方法诱导产卵,比较不同的暂养促熟方法和促熟培育时间对亲贝的性腺发育及催产效果的影响。结果表明:用室外土池人工促熟法,波纹巴非蛤亲贝性腺发育的成熟情况比室内水泥池促熟法好、死亡率低;且经室外土池人工促熟培育10 d,亲贝的性腺发育情况及催产效果最佳。更多还原

【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.更多还原
