摘　　要：为了解珠母贝早期发育阶段最适存活和生长条件，于2013年5—6月在珍珠贝养殖场进行不同海水盐度对珠母贝直线铰合期幼虫、壳顶期幼虫和稚贝生长及存活的影响实验。结果表明：珠母贝直线铰合期幼虫存活适宜盐度为2285—3886，最适盐度为2719—3502，壳长增长的适宜盐度为2043—4123，最适盐度为3110；壳顶期幼虫存活适宜盐度为2310-3914，最适盐度为2719—3502，壳长增长的适宜盐度为2029—4009，最适盐度为3110·3502；稚贝存活适宜盐度为2064—3910，最适盐度为2719—3502，壳长增长的适宜盐度为1938—4130，最适盐度为2719—3110。These experiments were carried out in the marine culture breeding field ofHaiwei, Leizhou, from May to June of 2013. In the condition of controlled sea salinity, the effects of salinity on the growth and survival of Pinctada margarilifera larvae and juveniles are studied. The results show- that the suitable salinity for the survival of Straight larvae is 22.85 38.86, the most suitable salinity is 27.19 35.02; the suitable salinity of growth is 20.43 41.23, and the most suitable salinity is 31.10. the suitable salinity for survival ofD larvaeis 23.10 39.14, and the most suitable salinity is 27.19 35.02; the suitable salinity for growth is 20.29-40.09, and the most suitable salinity is 31.10 35.02. the suitable salinity for the survival ofjuvenils is 20.64 39.10, the most suitable salinity is 27.19 35.02; the suitable salinity for growth is 19.38 41.30and the most suitable salinity is 27.19 31.10..
