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