Abstract: 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.
