Abstract

Accelerometer technology was used to evaluate behaviours in the teleost ambush predator pike Esox lucius foraging on crucian carp Carassius carassius. Automated rule-based estimates of prey-size determined handling time were obtained and are compared with video-recorded behaviours. Solutions to tag attachment and the limitations imposed by battery-time and data-logging capacities are evaluated.

摘要

加速度计技术被用于评估硬骨鱼伏击性捕食者白斑狗鱼（Esox lucius）捕食鲫鱼（Carassius carassius）时的行为。通过基于规则的自动化估计获得了确定处理时间的猎物大小，并将其与视频记录的行为进行比较。评估了标签附着的解决方案以及电池续航时间和数据记录能力所带来的限制。
