对企鹅珍珠贝胚胎及幼虫发生进行了显微观察．发现企鹅珍珠贝幼苗发生过程与其它双壳类相似．受精后，５５ｍｉｎ开始第 １次卵裂，其后为囊胚期和担轮幼虫期，在水温（２７±１）℃，２４ｈ出现Ｄ形幼虫，７ｄ进入壳顶幼虫期，２０ｄ成为眼点幼虫，大约在受精后２４ｄ变态和附着．文中还对幼苗培育过程的养殖管理及生产化人工育苗的有关问题进行了探讨． The penguin pearl embryo and larvae were microscopically observed. Found penguin shellfish seedlings occurred similar to other bivalves. After fertilization, the first cleavage began at 55 min, followed by the blastocyst stage and the larvae stage. D larvae emerged at water temperature (27 ± 1) ℃ for 24 h, entered the shell top larvae stage on the 7th day and became the spot larvae on the 20th day , About 24d after fertilization metamorphosis and attachment. The paper also discusses the breeding management of seedling cultivation process and the related problems of production artificial seedling.
