Cover Story: Estimating tail-beat frequency (TBF) is a crucial component of swimming kinematics and performance in fish, particularly because it provides information about energetics and behavioral responses to environmental cues. This paper proposes a novel approach using bioimpedance technology. This is the first time bioimpedance has been measured in a freely moving animal. An agreement analysis was then performed to compare a video-based reference measurement of TBF with the newly proposed approach. These results attest to the significant benefits of integrating bioimpedance sensors in biologgers, especially considering the complementary parameters that can be extracted from bioimpedance measurements, such as length, weight, condition index and fat content.
