Fig. 6. The relative timing of peak flow speed as a function of standard length. The timing of peak flow speed is expressed in fractions of the time to peak gape (TTPG), such that, at time 0, the gape equals 20% of the maximal gape and, at time 1, gape equals 95% of the maximal gape. The mean (± s.e.m.) relative timing of peak flow speed was 0.92 (±0.05). Data are mean values ± s.e.m. for each fish. The horizontal line (± gray band) represents the mean (± s.d.) timing of peak flow speed reported previously for intermediate sized bluegill (Day et al., 2005).
