摘　　要：试验结果表明:海水养殖杂交鲟的适宜温度为5.0～22.0℃,临界上限水温为26.0℃,临界下限水温为3.0℃;耐受盐度的范围比较广泛,为1.0～38.0,适宜养殖的盐度为8.0～32.0;耐pH值的范围为4.7～9.8,适宜养殖的pH值为6.9～8.8.杂交鲟对环境变化耐受性范围较大,可以保证杂交鲟可以更好地适应其生存环境,以避免由于环境因子的激变造成海水养殖杂交鲟的大规模死亡.Resistance of sturgeon hybrid to changes in water temperature, salinity, pH, light was determined in sea water condition in order to provide basic data for its aquaculture in sea condition. It was found that the adaptive water temperature ranges from 5.0 to 22.0℃ with the upper limit of 26.0℃ and lower limit of3.0℃. The suitable salinity varies from 8.0 to 32.0. The hybrid has adaptive pH values of 4.7 ～ 9.8 with the optimum of 6.9 ～ 8.8.
