Effects of hydropeaking on the attached eggs of a rheophilic cyprinid species
 BARTOŇ, Daniel
Ability of eggs of asp (Leuciscus aspius) to survive an increased water velocity was tested in experimental condition as well as in situ. Hydropeaking occurs on the study site and can cause detachment of most spawned eggs.

Effects of hydropeaking on the attached eggs of a rheophilic cyprinid species
 BARTOŇ, Daniel
Effects of artificial water fluctuations called hydropeaking on the detachment rates of adhesive eggs were studied using a rheophlic fish (asp Leuciscus aspius) as a model species. I attempted to relate egg density to abiotic conditions of the spawning ground and identify optimal conditions for the eggs. Egg densities were also studied during spawning season when hydropeaking occurred. In the experimental setup, egg detachment rates were tested with different speeds, substrate type and exposition time and critical conditions for the eggs were assessed.
