Juvenile sablefish, Anoplopoma fimbria (mean length 15.5 ± 1.9 cm, mean weight 68.5 ± 4.8 g), were used to evaluate the effects on growth, oxidative stress, and non-specific immune responses by changes of water temperature (8, 10, 12, 14, 16, 18, and 20 °C) and salinity (100 (35.0), 90 (31.5), 80 (28.0), 70 (24.5), 60 (21.0), 50 (17.5), and 40% (14.0) (‰)) for 4 months. The growth performance was significantly increased at the temperature of 12 and 14 °C, and the feed efficiency was notably decreased at the temperature of 18 °C. The growth performance and feed efficiency were also significantly decreased at low salinity. The antioxidant responses such as superoxide dismutase and catalase were significantly increased by the high temperature and decreased by the low salinity. The immune responses such as lysozyme and phagocytosis were elevated by the temperature of 18 °C and decreased by the salinity of 50%. The results of this study indicate that the growth performance of juvenile sablefish, A. fimbria, is influenced by the temperature and salinity, and the excessive temperature and salinity levels can affect the antioxidant and immune responses.
使用幼龄黑鲪（Anoplopoma fimbria，平均体长15.5±1.9厘米，平均体重68.5±4.8克），通过改变水温（8、10、12、14、16、18和20°C）和盐度（100（35.0）、90（31.5）、80（28.0）、70（24.5）、60（21.0）、50（17.5）和40%（14.0）（‰）），持续4个月，来评估对其生长、氧化应激和非特异性免疫反应的影响。在12和14°C的温度下，生长性能显著提高，而在18°C的温度下，饲料效率显著降低。在低盐度条件下，生长性能和饲料效率也显著降低。超氧化物歧化酶和过氧化氢酶等抗氧化反应在高温下显著增加，在低盐度下降低。溶菌酶和吞噬作用等免疫反应在18°C的温度下升高，在50%的盐度下降低。本研究结果表明，幼龄黑鲪的生长性能受温度和盐度的影响，过高的温度和盐度水平会影响抗氧化和免疫反应。
