摘要：利用室内工厂化育苗设施对缢蛏Sinonovacula constricta（Lamarck）进行人工催产，幼虫培育，盐度调控，育苗中后期直接投喂土池中天然藻类，减轻藻类培育负担，同步进行多批次苗种生产，大幅度增加了产量。2011年规模化苗种培育孵化率62.2%~70.7%，附着率52.2%~77.1%，幼虫成活率30.8%~60.2%，幼虫增重率为99.85%~99.96%，3个月内共催产915 kg种蛏，培育优质蛏苗约40亿粒。

Abstract: In this paper, it has been generally represented that the technique of large-scale artificial induction and breeding of Sinonovacula constricta larvae, and also the key process of the salinity control, algae production and distribution during the 19-25 days processing. After 3 months production, the model company got 40 billion larvae under a hatching rate of 62.2%-70.7%, attachment rate of 52.2%-77.1%, larval survival rate of 30.8%-60.2%.

Key words: Sinonovacula constricta; larvae breeding, large-scale production
