Recently spent adult dace Leuciscus leuciscus were captured from a known spawning site, radio‐tagged and released. Post‐release movements were monitored, and the habitat characteristics of the areas selected were recorded. Visual observations and electrofishing showed that all radio‐tagged fish were associated with other, untagged, adult dace. After spawning, dace occupied slow‐flowing shaded sites out of the main river channel. Within these areas, the fish were situated in the deepest and slowest‐flowing positions available. Possible reasons for the observed postspawning behaviour and habitat selection are discussed. ? 1998 The Fisheries Society of the British Isles
