海湾扇贝不同发育阶段耐干露的研究

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

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。

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.
