Fig. 6. Prochilodus costatus swimming speeds measured a in Upstream and downstream migration speed of Prochilodus costatus (Characiformes: Prochilodontidae) in upper São Francisco basin, Brazil

Fig. 6. Prochilodus costatus swimming speeds measured a. in this study in stretch 2 and b. in the laboratory by Santos et al. (2012). Central points are medians, boxes represent percentiles 25 and 75 and whiskers represent amplitude. Dashed lines separate different kinds of fish movements. BL/s = swimming velocity in standard length of fish per second.
