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

Popis výsledku v původním jazyce

Changes in Cyprinids behaviour belonging to different ecology groups were observed below the weir restricting their upstream migrations during the spawning period May - July. Positions of the chub Leuciscus cephalus (L.), Prussian carp Carrasius auratusgibelio (Bloch 1783), bream Abramis brama (L.) and white bream Blicca bjoerkna (L.) were recorded every 12 min. over a 24-hours period using an automatic data logger (ALS) in the upper Elbe River, Czech Republic. For all observed species, two peaks of their activity occurred, however, interspecies timing of the peaks differed. The peaks for chub, bream and white bream occurred at night and daylight, whereas the Prussian carp was active mostly at night. Specimens belonging to rheophilous group suggestedmore efficient behavioural tactics in passing the obstacle, and stayed below the weir one month longer than eurytopic species.
