在22℃和30℃条件下，利用改进的梭箱系统研究了红鱼对水中低氧的行为回避反应。分析了进入缺氧侧、每次进入缺氧侧的停留时间和进入缺氧侧的总时间的鱼在常氧和低氧侧之间的运动。适应30摄氏度增加了进入低氧行为开始的氧气阈值和总时间，而每次进入的停留时间没有变化。
Behavioural avoidance responses of red drum (Sciaenops ocellatus) to aquatic hypoxia were investigated at 22 and 30 degrees C using a modified shuttlebox system. Fish movement between a control side maintained at normoxia and a hypoxic side with stepwise decreasing water oxygen tension was analysed for entries into the hypoxic side, residence time per entry into the hypoxic side and total time in the hypoxic side. Acclimation to 30 degrees C increased the oxygen threshold for the onset of hypoxia avoidance behaviours for entries and total time, while residence time per entry was unchanged.
