The present study tests the precision of repeat homing of roach, Rutilus rutilus , to two tributaries of a small Norwegian Lake, Arungen. A sample of 19959 spawners was tagged or marked in the spawning area. After spawning the roach intermingled with other spawning demes in the lake. The year after marking, 2515 (12.6%) roach were recaptured during spawning in the five tributaries, 340 (13.5%) of these were strayers. This straying is considerably larger than found in comparable autumn spawning species, but approximately the same as reporter for other spring spawning species. The recapture rate was lower for females than for males, probably due to increased female mortality induced by the tagging manipulation.
