本文对青蛤Cyclinasinensis的室内人工催产、受精卵的孵化密度、幼虫培养密度、幼虫饵料及青蛤增养殖进行了研究。采用阴干、遮光和充气的方法对青蛤进行催产 ,成功率达 95% ;平均孵化率为 88.6 % ;室内育苗中 ,幼虫培养密度控制在 11～ 16个 /ml,幼虫变态后 ,减少培养密度 ,可以提高幼虫成活率 ;幼虫的饵料以叉鞭金藻为主 ,混合投喂较单一投喂效果更好。在 10 5.6 1m3水体的室内育苗池内 ,培育出稚贝约1.7亿粒 ,经土池培育获壳长 3～ 6mm幼贝 3878.4 5万粒 ,成活率为 2 2 .83%。另外 ,利用移苗和繁殖保护的方法 ,在 84hm2 养殖试验区进行青蛤增养殖 ,资源量由原来的 9.1个 /m2 增加到 2 2 .5个 /m2 ,净增资源量2 70 .7t。
In this paper, the indoor artificial production of Cyclina cylindrica Cyclinasinensis, hatching density of fertilized eggs, larval culture density, larval diet and clam culture were studied. The dark-colored clam was oxytocated by the methods of drying, shading and aeration, the success rate was 95%; the average hatching rate was 88.6%; in the indoor nursery, the density of larvae was controlled at 11 ~ 16 / ml. After larval metamorphosis, , Can improve the survival rate of larvae; larvae bait to goldenrod mainly dominated mixed feeding better than single feeding. Approximately 170 million juveniles were cultivated in indoor nursery ponds with 10 5.6 1m3 of water. After culturing in earthen ponds, 3878.4 50000 shells with shell length of 3 to 6 mm were obtained, with a survival rate of 22.83%. In addition, the use of seedlings and propagation protection methods, 84hm2 aquaculture trial area clam clam culture, resource resources from the original 9.1 / m2 to 22.5 / m2, a net increase of resources 2707.7t.
