Although animal-borne accelerometers are effective tools for quantifying the kinematics of animal behaviors, quantifying the burst movements of small and agile aquatic animals remains challenging. To capture the details of burst movements, accelerometers need to sample at a very high frequency, which will inevitably shorten the recording duration or increase the device size. To overcome this problem, we developed a high-frequency acceleration data-logger that can be triggered by a manually defined acceleration threshold, thus allowing the selective measurement of burst movements. We conducted experiments under laboratory and field conditions to examine the performance of the logger. The laboratory experiment using red seabream () showed that the new logger could measure the kinematics of their escape behaviors. The field experiment using free-swimming yellowtail kingfish () showed that the loggers trigger correctly. We suggest that this new logger can be applied to measure the burst movements of various small and agile animals.
尽管动物携带的加速度计是量化动物行为运动学的有效工具，但量化小型敏捷水生动物的爆发性运动仍然具有挑战性。为了捕捉爆发性运动的细节，加速度计需要以非常高的频率进行采样，这将不可避免地缩短记录持续时间或增加设备尺寸。为了克服这个问题，我们开发了一种高频加速度数据记录器，它可以由手动定义的加速度阈值触发，从而允许对爆发性运动进行选择性测量。我们在实验室和野外条件下进行了实验，以检验该记录器的性能。使用真鲷（）进行的实验室实验表明，新记录器可以测量它们的逃避行为的运动学。使用自由游动的黄尾鰤（）进行的野外实验表明，记录器触发正确。我们建议这种新记录器可用于测量各种小型敏捷动物的爆发性运动。
