Abstract:

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.
