摘　　要：就温度和盐度对滑顶薄壳鸟蛤 （ Ｆｕｌｖｉａ ｍ ｕｔｉｃａ Ｒｅｅｖｅ） 面盘幼虫存活和生长的影响进行了研究， 结果表明， 在盐度３２２ 条件下， 面盘幼虫存活和生长的最适温度为２１０ ～２４０ ℃， 存活的温度上限为２７０ ℃， 下限为１５０ ℃； 在２１０ ℃条件下， 面盘幼虫存活和生长的下限盐度为１４０ ， 最适盐度为２８０ ～３２２ ， 且在此盐度范围内， 随盐度升高， 面盘幼虫存活率和平均日生长率亦随之增大。Effects of temperature and salinity on survival and growth of hard clam (\%Fulvia murica\% Reeve) larva were observed at water temperature of 12,15,18,21,24,27,30,33℃and 13 salnity levels of 8.0～32.2 in a laboratory in Heishijiao (Dalian). At salinity of 32.2, there was no significance in survivalrate when the temperature was kept lower than 15℃ or higher than 27℃, and the optimum temperatures for survival and growth were between 21 and 24℃. In 21℃, the optimum salinity of survival and growth was in the range of \{28.0\}～\{32.2\}, and in which the survival and daily growth rate increased gradually with increasing salinity.
