| 摘 要： | 本文提出了泥螺室内人工育苗各阶段的技术措施,并就如何提高卵群的孵化率、几种药物在育苗中的应用作了扼要讨论。
在人工育苗过程中,0.28-0.9(×10-6)高锰酸钾,或5-9(×10-6)福尔马林处理卵群，可明显提高孵化率,对卵群膜的溶解有促进作用,并可提高卵群孵化的同步性。在面盘幼虫浮游期及匍匐期的培养过程中,采用0.5-1(×10-6)的高锰酸钾或5-10(×10-6)福尔马林可以有效地减少育苗水池中的有害微小生物。

| Abstract: | Bullacta exarata (Philippi) is monoecious, reproduction is by crossfertilization. The reproduce period is from the end of March to the last ten-days of November along the coast of Zhejiang Province. The fertilized egg is protected by an egg-capsule membrane After cleavage, it is developed to gastrula, then trochophora larva, which incubates at the viliger larva stage. During artificial spats-rearing, potassium permanganate 0.28-0.9(×10-6.)]can increase hatching rates During viliger and pediveliger rearing, potassium permanganate 0.5-1(×10-6)] or formalin 5-10(×10-6)] can reduce the amount of destructive microbes and animalcules.In the pediveliger stage, it must put in adherent sea-mud.
This paper presents artifical spats-rearing technology in various stages, suggests how to increase hatching rates and discusses the drugs during the rearing period. |
