Figure 3. Swimming kinematics in (A. anguilla) with a PSAT dummy.
A. Tail beat frequency (Hz) B. Tail beat amplitude (body lengths) and C. Body wave speed (body lengths) as a function of swimming speed (U, body lengths s−1) swimming with and without a PSAT dummy. Swim trials without (control) and with a tag (trials 2, 3) were performed on the same individual (N = 9). Lines are regression lines (refer to Table 2 for regression values). An asterisk denotes significant difference between control and tagged condition (Repeated measures ANOVA, p<0.05). Data are presented as mean±SD.
