Others Description:

My interest is focused especially on fry sampling in lakes and reservoirs using different
methods, development of freshwater trawling techniques and testing of trawl efficiency. I also studied distribution of different species of fish fry in horizontal (pelagial-littoral) and vertical (depth) scales. In my recent research I deal especially with distribution patterns of invasive gobiids and also newly stocked coregonids in recently created post mining lakes in the Czech Republic.
