Summary Roach were marked by fin‐clipping (N= 15888) or tagged with Carlin‐tags (N= 1476) during their spawning migration in two tributaries to Lake Årungen, Norway, in 1980. A total of 1746 of these roach were recaptured during spawning in 1981. The recapture rate of fin‐clipped roach was significantly higher than the recapture rate of Carlin‐tagged roach, probably due to differential mortality rates.
