摘要

Quantifying fine-scale locomotor behaviours associated with different activities is challenging for free-swimming fish. Biologging and biotelemetry tools can help address this problem. An open channel flume was used to generate volitional swimming speed (U_s) estimates of cultured lake sturgeon (Acipenser fulvescens Rafinesque, 1817) and these were paired with simultaneously recorded accelerometer-derived metrics of activity obtained from three types of data-storage tags. This study examined whethera predictive relationship could be established between four different activity metrics (tail-beat frequency (TBF), tail-beat acceleration amplitude (TBAA), overall dynamic body acceleration (ODBA), and vectorial dynamic body acceleration (VeDBA)) and theswimming speed of A. fulvescens. Volitional U_s of sturgeon ranged from 0.48 to 2.70 ms~(-1) (0.51-3.18 body lengths (BL) s~(-1)). Swimming speed increased linearly with all accelerometer-derived metrics, and when all tag types were combined, U_s increased 0.46 BLs~(-1) for every 1 Hz increase in TBF, and 0.94, 0.61, and 0.94 BLs~(-1) for every lg increase in TBAA, ODBA, and VeDBA, respectively. Predictive relationships varied among tag types and tag-specific parameter estimates of U_s are presented for all metrics. This use of acceleration data-storage tags demonstrated their applicability for the field quantification of sturgeon swimming speed.
