The swimming capacity of Barbus bocagei was measured with the critical swimming speed ( U crit ) standard test in a modified Blažka‐type swim tunnel. Sixty B. bocagei were tested and they exhibited a mean ± s . d . U crit of 0·81 ± 0·11 m s −1 or 3·1 ± 0·86 total lengths per second ( L T s −1 ). Sex had no effect on U crit but significant differences were found between the swimming performance of fish with distinct sizes.
