臭氧处理海水对扇贝卵的孵化及幼虫生长的影响

主要研究了用臭氧处理海水在经过连续充气曝气12、24h、不经充气曝气的处理水及没经臭氧处理的正常海水，进行海湾扇贝、虾夷扇贝受精卵的孵化和幼虫培育实验。结果表明，海湾扇贝受精卵在经过24h曝气的处理水中孵化率最高为92％，其次为没经过处理的正常海水为76％，曝气12h为16％，没经过曝气的为0；虾夷扇贝受精卵在经过24h曝气的处理水中孵化率最高为88%，其次为没经过处理的正常海水为85％，曝气12h为15％，没经过曝气为0。海湾扇贝幼虫培养在没经过处理的正常海水和经24h曝气的处理水中生长较快，曝气12h较慢；虾夷扇贝幼虫则是没经过处理的正常海水生长最快，其次是经24h曝气的处理水，而曝气12h较慢，成活率方面也表现出一定的差异，从而为臭氧处理海水在贝类育苗上的应用提供一定的指导。

Application of Ozonated Sea Water in the Seeding Process of the Bay Scallop (Argopecten irradians) and Japanese Scallop (Mizuhopecten yessoensis)

This paper describes the results of an experiment designed to compare the effectiveness of hatching zygotes of Bay and Japanese scallops and raising larvae with ozonated sea water charged for 0 hour, 12 hours and 24 hours, and non ozonated sea water. The results show that the hatching rate of Bay scallop zygotes in ozonated sea water charged for 24 hours was the highest at 92%. The hatching rate in non ozonated sea water was 76%,16% in ozonated sea water charged for 12 hours, and 0% in non charged ozona\|ted sea water. The hatching rate of Japanese scallop zygotes in ozonated sea water charged for 24 hours was the highest at 88%. The hatching rate in non ozonated sea water was 85%, 15% in ozonated sea water charged for 12 hours and 0% in non charged ozonated sea water. The growth rate of Bay scallop larvae in non ozonated sea water and ozonated sea water charged for 24 hours was the highest, and was lowest in ozonated sea water charged for 12 hours. The growth rate of Japanese scallop larvae in non ozonated sea water was highest and was lower in ozonated sea water charged for 24 hours, and the lowest in ozonated sea water charged for 12 hours. Moreover, the survival rate of larvae of both species varied. Consequently, the results offer guidance for the application of ozonated sea water in shellfish seeding.
