Abstract
Pike Esox lucius in the absence of prey and conspecifics were shown to have the highest habitat‐change activity during dusk and to decrease preference for complex habitats in turbid water. As the behaviours indicate routine responses in the absence of behavioural interactions, E. lucius spatio‐temporal distributions should be directly affected and thereby more easily assessed and avoided by prey, with potential consequences for encounter rates.
