| 摘要: |
| 利用海湾扇贝(Argopecten irradians)D形幼虫、眼点幼虫、稚贝、幼贝及成体作为材料,在8～10℃和20～22℃干、湿环境下通过干露不同时间对所取样品的成活率进行了比较研究。结果表明,海湾扇贝成体、D形幼虫、眼点幼虫、稚贝及幼贝在低温湿润的条件下干露时间长,而在高温干燥的条件下干露的时间短,其耐干能力为成 贝>眼点幼虫>D形幼虫>稚贝>幼贝。本实验为海湾扇贝幼虫的异地采苗、稚贝和幼贝的长途运输以及成贝低温干露保存提供了一定的 科学依据。 |

| Survival rate on the different stages of Argopecten irradians in the different exposure times |

| Abstract: |
| The paper studied the survival rate of Argopecten irradians under different temperatures(8～10℃ and 20～22℃) and moistures(dry and moist conditions). This experiment indicates in the conditions of moisture and low temperature, adult scallops, D-larvae, eye-spot larvae, juveniles, larval scallops still have high survival rate even under the long-time exposure, but under the high temperture and dry conditions they are able to endure short time exposure. The ability of enduring exposure was as follows: adult scallop>eye-spot larvae>D-larvae>larval scallop>juveniles. This study will supply references for A. irradians collection of seeding in remote place, transporting in long distance, and preserving adult scallop under low temperatures and dry exposure. |
