Fathead minnows Pimephales promelas maintained at 25° C for 6 h had significantly higher superoxide dismutase (SOD) activity than fish maintained at 7 or 32° C, but hypoxic conditions (3 mg l(-1) O2 ) over the same time period did not affect SOD activity. Fish in better body condition (length-adjusted mass) had higher SOD activity. In a separate experiment, P. promelas maintained at three water temperatures (7, 23 and 32° C) for 31 days did not differ in liver acrolein, a biomarker of oxidative stress.
在 25°C 下饲养 6 小时的胖头鱼 Pimephales promelas 的超氧化物歧化酶 (SOD) 活性明显高于在 7°C 或 32°C 下饲养的鱼，但在同一时间段内缺氧条件 (3mg l(-1) O2 ) 并不影响 SOD 活性。身体状况较好的鱼（体长调整质量）的 SOD 活性更高。在另一个实验中，在三种水温（7、23 和 32°C）下饲养 31 天的胖头鱼 Pimephales promelas 的肝丙烯醛（氧化应激的生物标志物）没有差异。
