Locomotory behaviour and physiology of fish: an evaluation of tradional protocols and development of new and improved methodologies

在过去，对鱼的游动能力感兴趣的研究人员研究了被放置在小型“鱼跑步机”中的个体。最近的研究表明，这些跑步机会导致鱼在肌肉筋疲力尽之前停止游泳，这意味着鱼的行为对研究结果产生了影响。这项工作将研究为什么在跑步机上的鱼提前停止游泳，以及由于之前未知的行为疲劳的发生，哪些科学原理可能是有缺陷的。此外，鱼的跑步机不太适合测量高速游泳，因为对于鱼来说，它们太小了，无法使用通常可以节省能量的某些游泳模式。因此，我们将研究在长长的赛道上高速游泳，那里的鱼有移动的空间，并可以自由使用节省能源的策略，就像它们在野外所做的那样。预计这些信息将非常有用，因为它将更适用于自然界中的野生鱼类，而不是来自迫使鱼类在小型跑步机上游泳的测试数据。

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.
