Název v původním jazyce

Impact of flood on distribution of bathypelagic perch fry layer along the longitudinal profile of large canyon-shaped reservoir

Popis výsledku v původním jazyce

Previous studies have shown that in normal spring conditions, the layer of bathypelagic perch Perca fluviatilis fry (BPF) is equally distributed along most of the longitudinal profile of reservoirs. Flood hitting the Orlík Reservoir (Czech Republic) completely flushed the existing fry community out from the 31 km long riverine part of the reservoir. The pelagic zone in this reach was then recolonized by cyprinid fry being of either littoral or riverine origin. Subsequently, the BPF layer was recorded only in the 22 km long lacustrine part of the reservoir. In the upper reach of this part where water current slowed down in large volume and fry originated from both riverine and central part of the reservoir flocked in high numbers, two distinct BPF layers were observed. The results from acoustic survey and complementary net catches suggest that no epipelagic perch fry were found in the reservoir where thermal stratification had been destroyed by flooding and windy weather.
