Behavioural pattern in cyprinid fish below a weir as detected by radio telemetry

Original language description

Changes in the behaviour of cyprinids belonging to different ecology groups were observed below a weir that was restricting their upstream migrations during the spawning period May-July. Positions of chub Leuciscus cephalus (L.) jelec tloušť, Prussian carp Carrasius auratus gibelio (Bloch 1783) karas stříbřitý, bream Abramis brama (L.) cejn velký and white bream Blicca bjoerkna (L.) cejnek malý were recorded every 12 min over a 24-h period using an automatic data logger (ALS) in the upper Elbe River, Czech Republic. For all observed species, two activity peaks occurred; however, the interspecies timing of these peaks differed. Peak times for chub, bream and white bream occurred at night and during daylight, whereas Prussian carp was active mostly at night. Specimens belonging to the rheophilous group suggested more efficient behavioural tactics in passing the weir, staying below the obstacle one month longer than did eurytopic species.
