2007-2011年,在34口面积共为100.17 hm2的土池中将阴干的青蛤挂于竹筏上进行流水刺激,催产63次,获得受精卵8150.55-108粒, D形幼虫1970.74×108只,孵化率为24.18%;幼虫正常发育变态为稚贝423.85-108粒,变态率达21.51%;培育到壳长0.50 cm的苗,收获377.02-108粒,育成率达88.95%;平均产量达3.76-108粒/hm2,达到规模化生产要求。
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.
