Habitat choice and migration behaviour of large roach in relation to its predators has rarely been investigated in natural systems so far. In the present study, the occurrence of large roach was negatively coupled with the occurrence of potential predators. The behavioural response to predators of roach was clearly length-dependent, since the patterns of diel habitat choice differed between large and small roach. For lake-wide estimates of trophic interactions, it is therefore highly recommended to separate size groups of prey, since size dependent trait changes may impact habitat-specific resources in a contrasting way.
