Swimming ability and differential use of velocity patches by 0+ cyprinids

Abstract– The ability of chub, dace and roach to resist displacement in a laboratory channel was not only controlled by species-specific swimming ability, but also by the fishes'ability to locate areas of reduced velocity. Dace were better able to withstand high velocities than roach. Chub were better at locating slow flowing patches than either roach or dace throughout their early development. Only chub larvae shifted towards slower flowing patches as velocity increased. All juveniles shifted to slower flowing patches at high velocities.
