Synopsis
Chemical cues from piscivorous fish and prey alarm substances often cause rapid fright responses in prey. However,
little is known of how piscivore-related chemical cues affect prey behaviour over periods longer than a few hours.
Here we have investigated how chemical cues from piscivorous northern pike, Esox lucius, affect habitat choice
and diel activity of crucian carp, Carassius carassius, over an extended period, 11 days. At the beginning of the
