Investigating the threat of non-native North American signal crayfish (Pacifastacus leniusculus) to salmon redds

1. To test their ability to detect and excavate Atlantic salmon eggs (Salmo salar) in an artificial redd, North American signal crayfish (Pacifastacus leniusculus) were exposed to three successive experimental treatments. 2. Crayfish successfully detected and excavated buried fish but were unable to...
