一种新型的数据记录器，包括一个3轴陀螺仪，一个3轴加速度计，和一个3轴磁力计的开发和外部连接到日本琥珀，塞尔维亚quinqueradiata，调查使用该设备的可能性，用于监测运动性能的快速启动行为的鱼在该领域。触发的逃逸行为，同时测量的数据记录器（500赫兹）和高速摄像机（200赫兹）在坦克。通过使用陀螺仪，数据记录仪准确地重建了基于重力的加速度，三维姿态，动态加速度和鱼在快速启动运动期间的角速度，这是以前仅使用加速度计和磁力计的方法无法实现的;因此，这些变量可用于评估鱼的距离相关性能和机动性。逃生运动可以分为两种机械类型（单弯和双弯）使用所获得的运动变量，这表明运动类型之间的显着差异。这些结果表明，使用这种动物安装的数据记录器，以量化的运动性能的快速启动行为的鱼类在自然界中的可能性。(C)2013爱思唯尔有限公司版权所有。
A novel data logger incorporating a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer was developed and externally attached to Japanese amberjacks, Serbia quinqueradiata, to investigate the possibility of using this device for monitoring the movement performance of the fast-start behaviour of fish in the field. Triggered escape behaviours were measured simultaneously by the data logger (500 Hz) and a high-speed camera (200 Hz) in a tank. By using a gyroscope, the data logger accurately reconstructed the gravity-based acceleration, 3-dimensional attitude, dynamic acceleration, and angular velocity of fish during the fast-start movement, which was impossible by previous methods using only an accelerometer and a magnetometer; these variables can therefore be used to assess the distance-related performance and manoeuverability of fish. The escape movements can be categorised into two mechanical types (single- and double-bend) using the obtained locomotor variables, which showed significant differences between movement types. These results indicate the possibility of using this animal-mounted data logger to quantify the movement performance of the fast-start behaviour of fish in nature. (C) 2013 Elsevier B.V.
