摘要
凡纳滨对虾（Litopenaeus vannamei）在不同盐度（4，18，32）和温度（22-26℃）水体中养殖，分别于1，5，15和30d后取样，进行不同盐度下凡纳滨对虾血淋巴免疫生理指标比较。结果表明：盐度对凡纳滨对虾血淋巴酚氧化酶、超氧化物歧化酶、酸性磷酸酶和碱性磷酸酶活力均有显著影响（P〈0．05）。盐度由32渐变至设定盐度后，实验前期（15d之内），盐度4和18组凡纳滨对虾上述各项指标均呈现一定的波动趋势，至15d后趋于稳定；盐度32组在整个实验过程中基本稳定。稳定后的各项指标均表现在盐度18时最高，盐度4时次之，盐度32时最低。
Litopenaeus vannamei were acclimated for 1, 5, 15 and 30 days at different salinities （4, 18 and 32 at 22-26℃）, and the immune and physiological parameters in the haemolymph of Litopenaeus vannamei at different salinities were analysed and compared. The results showed that the influence of salinity on the activities of phenoloxidase, superoxide dismutase, acid phosphatase and alkaline phosphatase were very remarkable （P 〈 0.05）. Upon reduction from salinity 32, the enzyme activities mentioned above showed different change tendencies and became stabilized after 15 days at salinities 4 and 18, and no obvious change was observed at salinity 32. After stabilizing, the peak activity of all the enzymes appeared at salinity 18, and the activity was higher at salinity 4 than 32.
