Description	Long-term catch-records from sport anglers can be used as a significant indicator of changes in the distribution and population size of some fish species, as well as the effects of stocking. Evaluating 50-year series of records in the Czech Republic we conclude that there is a marked decrease in the numbers of Barbus barbus, Chondrostoma nasus, Vimba vimba and Leuciscus cephalus, i.e. species chracteristic of the Barbus type fish community. This is the results of a gradual but marked restriction of this community type in individual streams caused by dam construction and canalisation. Catches of Thymallus thymallus have shown a marked increase in size, resulting from the increased extent of suitable waters caused by damming and from intense stocking with yearlings of the species. Catches of Salmo truta m. fario and Thymallus thymallus indicate heavy predation pressure exerted by cormorants (Phalacrocorax carbo) upon these species in a section of one river, the river Dyje below a dam.
