| 摘 要： | 栉孔扇贝Chlamys farreri (Jones et preston)的人工育苗研究,在我国已有十余年的历史。室内培育阶段已有一套较为完整可行的培育方法。但至今,对如何提高稚贝出池后海上中间培育阶段的保苗率,众家纷纭,尚无成熟经验,保苗率很低,以致影响栉孔扇贝的苗种生产。为了探索提高扇贝稚贝出池后在海上中间培育阶段的保苗率的措施,我们于1983年采用正交试验法,对海上中间培育阶段

THE EXPERIMENT ON RAISING SURVIVAL RATE OF Chlamys farreri (JONES ET PRESTON) IN TEMPORARY FEEDING STAGE |
| |
| Abstract: | The writer uses the perpendicular method to raise the survival rate of Chlamys farreri (Jones et Preston). There are many factors aifecting the survival, they are: time for removing from rearing tank, opening of the sack mesh and so on. Separation of seeds into different sack is preferred after 15-20 days. If seed density is too large, more substrate material should be added to the sack. The sack is preferrably of one layer with sack mesh opening of 15-34. Wind and wave are also important factors affecting the survival rate. |
