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。
The results showed that the suitable temperature for marsh hybrid sturgeon was 5.0 ~ 22.0 ℃, the critical upper limit temperature was 26.0 ℃, the lower limit critical temperature was 3.0 ℃, and the tolerable salinity range was 1.0 ~ 38.0. The salinity Is 8.0 ~ 32.0; the range of pH value is 4.7 ~ 9.8, the suitable culture pH value is 6.9 ~ 8.8. Hybrid sturgeon has a wide range of tolerance to environmental changes, which can ensure that hybrid sturgeon can adapt to its living environment better, so as to avoid the large-scale death of marsh hybrid sturgeon caused by the change of environmental factors.
