The effects of salinity on the embryonic and larvae stage of were investigated. Fertilised eggs and one day old D-larvae were subjected to salinities ranging from 0 to 30 ppt at temperature of 30±2°C. At salinity lower than 10 ppt, 100% mortality was observed. For embryo development, the highest survival was observed at salinity 25 ppt with 80.9±2.2% survival with no significant difference compared to 15 and 30 ppt. Shell height and length were both greatest at salinity 30 ppt. Throughout the 11 days culture, the highest larval survival occurred at salinity 15 ppt with no significant difference compared to all other salinities except 10 ppt. Larval shell sizes showed no significant differences between salinities, except for 10 ppt. Optimum culture condition for larvae growth are salinities ranging from 15 to 30 ppt whereby the larval of this species can tolerate wider range of salinity compared to other oyster species and thus, making it a competitive species to be cultured.
研究了盐度对[具体物种未明确]胚胎和幼虫阶段的影响。将受精卵和1日龄的D型幼虫置于温度为30±2°C、盐度范围为0至30 ppt的环境中。在盐度低于10 ppt时，观察到100%的死亡率。对于胚胎发育，在盐度25 ppt时观察到最高存活率，为80.9±2.2%，与15 ppt和30 ppt相比无显著差异。壳高和壳长在盐度30 ppt时均最大。在整个11天的培养过程中，幼虫存活率最高出现在盐度15 ppt时，与除10 ppt外的所有其他盐度相比无显著差异。除10 ppt外，幼虫壳大小在不同盐度之间无显著差异。幼虫生长的最佳培养条件是盐度范围为15至30 ppt，与其他牡蛎物种相比，该物种的幼虫能够耐受更宽的盐度范围，因此使其成为具有养殖竞争力的物种。
