Study on Juveniles of Lutraria sieboldii's Adaptability to Salinity

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.
