【摘要】 试验在黄砂、海泥和不投附着基三种状态下,观察了青蛤幼虫在变态时期的附着量和成活率的变化,以及附着后稚贝的生长与成活情况。结果表明:海泥是青蛤工厂化育苗最适宜的附着基,然后在此基础上进行了不同厚度海泥对不同大小稚贝生长的影响试验。试验结果显示:不同厚度的海泥对稚贝生长的影响不明显。我们认为在生产中应选用1mm厚度的海泥做为青蛤育苗的附着基是最适宜的。更多还原

【Abstract】 The assay is designed to evaluate the effect of different adhering material on survival and growth rate of Cyclina sinensis larva in economic culture.Adhering assay is under the three states: using yellow sand,sea mud and without any adhering substance.We observed adhering amount and adhering rate of the young shellfish and survival of young shellfish after adhesion.We found that the sea mud is most suitable for adhesion.After that we evaluated the effect of different thickness of sea mud on young shellfish growth.The result shows: Sea mud is most suitable adhering substance in the economic cultivation Cyclina sinensis and the most suitable thickness of the sea mud for Cyclina sinensis larva growth is about 1mm.更多还原
