Hydrology and angler's catches in the Czech reservoirs

Original language description

Anglers' catch statistics are used to examine the fish species composition in 15 Czech reservoirs with different ecohydrological conditions. Three groups of reservoirs were defined: 1. reservoirs with a relatively natural regime ("natural reservoirs"), 2. cascade reservoirs and 3. reservoirs with extreme power generating use ("extreme reservoirs"). Two ordination analyses revealed differences between reservoirs.Fish species composition in cascade reservoirs differs from that in the other types. Extremereservoirs have a much higher stocking rate of cyprinid species thanother reservoirs. Stocking could 'recover' fish species composition even in reservoirs with very disturbed ecohydrological conditions, so the anglers' catch composition is similar to 'natural reservoirs'. Bream/perch ratio in the anglers' catch was found tobe a good criterion to differentiate between the reservoirs types. It is negatively correlated with water level fluctuation and
