Název v původním jazyce

A telemetry study on the diurnal distribution and activity of adult pikeperch Sander lucioperca (L.) in a riverine environment

Popis výsledku v původním jazyce

The diurnal movements and spatial distribution of adult pikeperch in the Elbe River, Czech Republic was observed using radio telemetry. The hypotheses that i) pikeperch diurnal movements in a river would follow behavioural pattern in a drainage canal andii) light intensity, within four different intervals (dawn, day, dusk, night), would determine the spatial distribution of pikeperch were tested across the time span of twelve months. During the day, fish were located in deep water of the main channel,moving towards shallower waters during twilight and residing in the littoral zone, closest to the riverbanks at night. Movement activity followed behavioural pattern in a drainage canal with maximum at twilight and minimum at night. This suggests that nocturnal positions of adult pikeperch in the shallows were not associated with hunting but more likely with resting.
