U opt is not affected by added drag, validating previous findings of telemetry studies. Quantification of added drag effect on COT and U crit show a (limited) correlation, suggesting that the U crit test can be used for evaluating external tags for telemetry studies until a certain threshold value. Attachment at 0.125 bl from the tip of the snout is a better choice than at the Centre Of Mass (0.35 bl), as it is the case in current telemetry studies. The results show a significant effect of a) attachment site and b) drag on multiple energetic parameters, such as Cost Of Transport (COT), critical swimming speed (U crit) and optimal swimming speed (U opt), possibly due to changes in swimming kinematics. ![]() Using an integration of swimming physiology, behaviour and kinematics, we investigated the effect of additional drag and site of externally attached tags on swimming mode and costs. Due to their high swimming efficiency, anguilliform swimmers are very susceptibility for added drag. However, external tags are known to impair swimming energetics dramatically in a variety of species, including the endangered European eel. Telemetry studies on aquatic animals often use external tags to monitor migration patterns and help to inform conservation effort. ![]()
