| Abstract: | 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 |
