盐度对施獭蛤稚贝存活及生长的影响

Study on Juveniles of Lutraria sieboldii's Adaptability to Salinity

在水温26.8-31.8℃、PH值7.8-8.1室内条件下,于12.8-37.1盐度范围设置10个梯度,观察不同海水盐度对施獭蛤（Lutraria sieboldii）稚贝存活及生长的影响。结果表明：施獭蛤稚贝适宜生存盐度为19.8-33.8,最适宜生存盐度为26.3-31.7;适宜生长盐度为21.9-33.7,最适宜生长盐度为26.3-29.0。

When temperature and PH ranged between 26.8-31.8 ℃ ,7.8-8.1 respectively, studying effectss of various seawater salinities on growth and survival of juveniles of Lutraria sieboldii were investigated by adopting indoor control measures, by setting ten salinity gradients ranged between 12.8-37.1. The results showed that the salinity suitable for survival is 19.8-33.8,of which the optimum is 26.3-31.7, the salinity suitable for growth is 21.9-33.7, of which the optimum is 26.3-29.0, the suitable survival salinity is 19.8-33.8, the optimum survival salinity is 26.3-31.7, the suitable growth salinity is 21.9-33.7, the optimum growth salinity is 26.3-29.0.
