Muscle lactate metabolic recovery in sea bass juveniles was studied in respect to the water temperature. The fish used in this study were cultured with the semi-extensive mesocosm method, and the water temperatures were 15 and 20 degrees C. Fish were led to exhaustion by exercising in a swimming channel, and the muscle lactate levels were measured seven times before and after exercise. The results showed that muscle lactate concentration rises during exercise until it reaches a maximum (exhaustion point), and then it keeps falling during the recovery time. Also, fish exercised at 20 degrees C exhibited higher lactate values at the exhaustion point and faster decomposition rates during recovery.
本研究旨在探讨鲈鱼幼鱼的肌肉乳酸代谢恢复情况与水温的关系。实验所用鲈鱼采用半集约化中密度养殖方式，水温分别为 15 和 20 摄氏度。在游泳通道中使鱼力竭以进行运动，在运动前后七次测量肌肉乳酸水平。结果表明，运动过程中肌肉乳酸浓度上升，直至达到最大值（力竭点），然后在恢复过程中持续下降。此外，20 摄氏度下运动的鱼在力竭点显示出更高的乳酸值，且在恢复过程中分解速度更快。
