Striped Bass naturally inhabit a wide range of temperatures, yet little is known about the processes that control their acute and chronic temperature limits. The objective of this study was to determine the effect of temperature acclimation on acute thermal maxima and physiology of juvenile Striped Bass. Juvenile fish were acclimated to 15, 25 or 30 °C for 4 weeks, then split into two sampling groups: post-acclimation and post-critical thermal maximum trials. We found that fish survived in all acclimation temperatures with little change to underlying hematology, and that critical thermal maximum (CT_max) increased with increasing acclimation temperature. At CT_max, fish acclimated to 30 °C had elevated plasma cortisol, lactate and potassium levels. These results suggest that, while 30 °C is likely to be outside their thermal optima, Striped Bass can survive at high temperatures. This ability to cope with warm temperatures may provide an advantage with increasing global temperatures.

条纹鲈鱼自然栖息在很宽的温度范围内，但对于控制其急性和慢性温度极限的过程知之甚少。这项研究的目的是确定温度适应对少年条纹鲈的急性最大热和生理的影响。将幼鱼在15、25或30°C的环境中适应4周，然后分成两个采样组：适应后和临界后最高热量试验。我们发现鱼在所有适应温度下都可以生存，而基本血液学几乎没有变化，并且临界热最大值（CT _max）随着适应温度的升高而增加。在_最大CT，适应30°C的鱼血浆皮质醇，乳酸和钾水平升高。这些结果表明，尽管30°C可能超出了其最佳温度，但条纹鲈鱼仍可以在高温下生存。这种应付温暖温度的能力可以在全球温度升高的情况下提供优势。
