摘　　要：研究了山东地区缢蛏人工繁育过程及盐度对幼虫生长的影响。结果发现,山东地区能够顺利培育缢蛏苗种,其受精卵在23℃条件下发育24 h便可进入D形幼虫阶段,浮游期约为8 d,每天生长约15μm,变态后生长速度稳步加快;将幼虫在14、21、28盐度梯度下培育发现,随着盐度的升高,其壳长生长速率显著下降(P<0.05)。该研究结果可为山东地区开展缢蛏人工繁育提供参考。The artificial breeding process of razor clams in Shandong and the effects of salinity on the growth of larvae were studied.The results showed that razor clam could be successfully propagated in Shandong,and their fertilized eggs could enter the D-shaped larval stage after 24 h of development at 23°C.The larval stage was about 8 days,with a growth rate of about 15μm per day,and the growth rate steadily accelerated after larval stage;the larvae were bred under three salinity of 14,21 and 28,and it was found that the shell length growth rate decreased significantly with the increase of salinity(P<0.05).The results of the study provide a reference for the artificial propagation of razor clams in Shandong.
