泥蚶亲贝工厂化人工培育技术研究

ON TECHNIQUE FOR INDUSTRIAL PARENT REARING OF BLOODY CLAM TEGILLARCA GRANOSA

于2001年3～4月在浙江乐清进行了泥蚶亲体工厂化人工促熟培育,前期饵料以小新月菱形藻、微绿球藻为主,后期待温度升至25℃以上时,投喂微绿球藻、金藻、扁藻。室内培育时间30～45d即能达到生产标准,比自然成熟提前20～30d。

An experiment of industrial parent rearing of bloody clam Tegillarca granosa was made at Leqing, Zhejiang Province during March to April, 2001. The parent bloody clam were mainly fed on Nitzschia closteriun and Nannochloropsis oculata first. Later, when the water temperature raised to more than 25℃ , they were fed on Nannochloropsis oculate, Isochrysis galbana and Platymonas . The parent bloody clam matured and spawned after rearing for 30 - 45days. The spawning time was 20 - 30 days earlier than natural spawning.
