Abstract

The response of bleak (Alburnus alburnus (L.)) to alarm substance (from skin extract of conspecifics) was quantified, using a video camera, in laboratory experiments across two light and one dark periods (18 hrs). In the light alarm substance induced hiding in refuges (vegetation) and formation of aggregations. There was no such reaction during darkness or during a second light period.
