The aim of the study was to monitor the burbot populations in four reservoirs and in a pond with previous stocking. The monitoring was carried out during the spring season 2016 and, in the case of the Nýrsko Reservoir, during winter and summer as well. The combination of harmless methods (traps of two types, visual survay, electrofishing, hydroacoustic), a method simulating fishing pressure (long-lines) and a fix-frame trawl were used to detect burbot. A novel monitoring scheme was developet and validated and burbot populatin characteristics described.
