几种环境因子对厚壳贻贝浮游幼虫生长与存活的影响

Influences of Some Environmental Factors on Growth and Survival of Mytilus coruscus Gould Larvae

研究了在室内控制条件下,海水盐度、温度、pH对厚壳贻贝浮游幼虫生长和存活的影响。结果表明,厚壳贻贝浮游幼虫生长的适宜盐度在15～35,最适生长盐度在25～35之间,适宜温度为15～30℃,最适生长温度在20～25℃,适宜pH为6.00～9.00,最适pH为8.00左右。

Under the conditions of controlled seawater salinity, temperature and pH, the influences of salinity, temperature and pH on the growth and survival of Mytilus coruscus Gould larve were studied respectively. The results showed that the suitable salinity was 15-35 for larvae ,and the most suitable salinity was 25-35, the suitable temperature was 15-30℃, and the most suitable temperature was 20-25℃, and the suitable seawather pH was 6.00-9.00, the growth was the best and the survival rate was the highest at seawater pH value was 8.00.
