In the past, researchers interested in the swimming ability of fish studied individuals that were placed in small "fish treadmills". Recent work has shown that these treadmills can cause fish to stop swimming before their muscles become exhausted, which means that fish behaviour is having an effect on the results of the research. This work will study why fish in treadmills stop swimming early, and what scientific principals may be flawed due to the previously unknown occurrence of behavioural fatigue. In addition, the fish treadmills are not very good for measuring high speed swimming, because they are too small for fish to use certain swimming modes that would normally save them energy. As such, we will be studying high speed swimming in long raceways, where fish have room to move and are free to use strategies that save energy, as they do in wild. It is expected that this information will be very useful, as it will be more applicable to wild fish in nature than data from the tests that force fish to swim in the small treadmills.

在过去，对鱼类游泳能力感兴趣的研究人员研究了被放置在小型“鱼类养殖场”中的个体。最近的研究表明，这些游泳池可以导致鱼类在肌肉耗尽之前停止游泳，这意味着鱼类的行为对研究结果产生了影响。这项工作将研究为什么鱼在淡水养殖场停止游泳早，什么科学原理可能是有缺陷的，由于以前未知的行为疲劳的发生。此外，鱼类游速器不太适合测量高速游泳，因为它们太小，鱼类无法使用通常会节省能量的某些游泳模式。因此，我们将研究在长跑道中的高速游泳，在那里鱼有移动的空间，可以自由地使用节省能量的策略，就像它们在野外一样。预计这一信息将非常有用，因为它将更适用于自然界中的野生鱼类，而不是强迫鱼类在小型游泳池中游泳的测试数据。
