摘　　要：近江蛏人工育苗技术包括亲贝人工催产、饵料生物培养、浮游幼虫和稚贝培育等过程。近江蛏受精卵卵径约(91.52±2.69)μm,为沉性卵;在温度26.5~27.0℃、盐度7~13、pH 8.2条件下,受精卵经过20~24 h发育至D形幼虫;从孵化到附底需要6~7 d。浮游幼虫前期投喂金藻,后期混合投喂金藻和角毛藻,稚贝期投喂骨条藻和室外池塘定向培养的硅藻水;选用经消毒过的活性淤泥作为幼虫变态附着基。本文筛选出近江蛏受精卵孵化及幼虫生长的适宜环境条件,并进行了不同温度、盐度、饵料生物及附底基质的附苗效果实验,总结了一套近江蛏工厂化人工育苗技术工艺,为近江蛏工厂化人工育苗从业者提供基础资料。The artificial breeding technology of Sinonovacula rivularis includes the processes of artificial induction of parental shellfish,food biological cultivation,plankton larvae and juvenile cultivation.Fertilized eggs of S.rivularis had a diameter of about(91.52±2.69)μm,which were sinking eggs.Under the conditions of water temperature of 26.5~27.0℃,salinity of 7~13 and pH of 8.2,the fertilized eggs would develop after 20~24 hours to D-shaped larvae.It took 6 to 7 days from hatching to set.Planktonic larvae were fed with Chrysophyta sp.in the early stage,fed with the mixture of Chrysophyta sp.and Chaeroeeros sp.in the later stage,and Skeletonema sp.and diatom water from outdoor ponds were fed in the juvenile stage.The activated silt that had been disinfected was used as the larval metamorphic attachment base.This paper screened out suitable environmental conditions for the hatching of zygote eggs and growth of the larvae,and carried out the experiment on the effect of different water temperature,salinity,bait and substrate attached to the seedlings.Practitioners of factory artificial seedlings of S.rivularis provided basic information.
