Název v původním jazyce

Distribution of the bathypelagic perch fry layer along the longitudinal profile of two large canyon-shaped reservoirs

Popis výsledku v původním jazyce

The distribution of the bathypelagic perch Perca fluviatilis fry (BPF) layer was studied along the longitudinal profiles of Slapy and Orlík Reservoirs (Czech Republic). In Slapy Reservoir, the BPF layer was recorded from the dam for 29 km upstream. The BPF layer vanished in the upper third of the reservoir due to the cold hypolimnetic water discharged from Orlík Reservoir situated upstream in the cascade. Both abundance and size of BPF increased significantly upstream following the trophic gradient. InOrlík Reservoir, the BPF layer was recorded along the whole longitudinal profile of the reservoir (over 50 km, filled with relatively warm water). Both the sizes of BPF and their shoaling activity again increased significantly from the dam towards the inflow following the trophic gradient. Pooling the data from both reservoirs, it was evident that the tendency to flock in a dense layer and, much later, to create distinct shoals, increased continuously with the size of BPF.
