The critical swimming speed of Iberian barbel Barbus bocagei in relation to size and sex
Abstract:The swimming capacity of Barbus bocagei was measured with the critical swimming speed (Ucrit) standard test in a modified Blažka-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.
