利用自然海水和天然饵料，采用无泥砂采苗方法，在天津沿海成功开展了青蛤工厂化育苗。幼虫初始壳长（120±1．28）μm ，壳长平均日增长5．05μm ，成活率23．0％；第19～31 d为变态期，壳长平均日增长14．1μm，变态率32．9％；变态后至第53d，壳长平均日增长32．5μm，成活率82．3％。本次育苗试验充分利用天津沿海水质条件与环境特点，改进育苗方法，建立了适于天津海区的青蛤人工育苗工艺，共得到双水管稚贝约1．25亿枚。

Factory breeding of Cyclina sinensis was successfully carried out in Tianjin coast by the u-sing natural sea water ,natural food and settlling without mud and sand .In the larval stage ,the initial shell length of larvae was 120 ± 1 .28 μm ,the average daily growth of shell length was 5 .05 μm ,the survival rate was 23 .0% ;During 19~31 day in which larvae were in metamorphosis stage ,the average daily growth of shell length was 14 .1μm ,metamorphosis rate was 32 .9% ;From metamorphosis to 53 day ,the average daily growth of shell length was 32 .5 μm ,the survival rate was 82 .3% .The breeding experiments take advantage of water quality conditions and environmental characteristics in the Tianjin coast ,improve breeding methods ,and establish the Cyclina sinensis breeding method in the Tianjin coast .In total ,about 125 million double siphon juveniles were harvested .
