| Abstract: | In order to improve the hatching rate and yield, the dried Cyclina sinensis were hung on the bamboo raft, then stimulated by flowing water and induced spawning 63 times in 34 earth ponds of a total area of 100. 17 hm2 from 2007 to 2011. 815. 055 billions of fertilized eggs and 197. 074 billions of D-shaped larvae were obtained. The hatching rate was 24. 18%. The larvae metamorphosed into 42. 385 billion juveniles, the meta-morphosis rate was 21. 51%, the seedlings of 0. 5 cm shell length was 37. 702 billion, the rearing rate was 88. 95%,harvested average 376 million seedlings per hectare, it achieved the requirements of large -scale yield breeding. |
