| 摘 要： | 通过观测莱湾海湾扇贝８￣１０月内脏得率及肉柱得率的变化规律，对海湾扇贝的秋季生殖习性进行探讨，认为：海湾扇贝用秋季半人工育苗法替代室内加温育苗法可获得较好苗种，投放采苗袋２０天后，秋苗平均壳高４．９６ｍｍ，产卵前，内脏得率呈上升趋势，之后下降；肉柱得率一直呈上升趋势。

| Abstract: | According to survey on its changing law of the adductor-producing rate in haizhou Bayfrom Aug. to Oct.,we enquired into repoduction habit of Argopecten irradians in autumn. We hold that good seeds may be obtained with the method of semi-artificial seed-collecting in autumn instead of the method of indoor seed-rearing by increasing water temperature. After releasing the seed-collecting bags, 20 days later the average shell-height of the autumn seeds was 4. 96mm. Rising trend of the adductor-producing rate of the adult scallops emerged. |
