Description

I am interested in causes and consequences of various migration strategies of cyprinid fish termed asp (Leuciscus aspius). Males of this species are protandric, meaning that they arrive earlier and leave the spawning ground later on the seasonal and also partly on daily basis. Since asp is long-lived iteroparous species, I am interested how reproductive strategies of males and females change with their experience. We also adress effect of hydropeaking on the eggs of preophilous fish, which are periodically swept down by hydropeaking events on the study site. 

Another research topic I investigate are invasive species and their impacts on native fauna with specific interest in competition between native and critically endangered crucian carp (Carassius carassius) and invasive Prussian carp (C.gibelio).
