Abstract: Faunistical survey and community structure (relative frequency) data collection were carried out to follow the structural composition of fish populations. Considerable change was revealed in the abundance pattern of the fish stock during the study due to the intensive fishing impact being continuous in the reservoir since 1988. The overall dominancy of non-indigenous species has been detected (Carassius auratus gibelio, Pseudorasboda parva, Lepomis gibbosus) together with the important decrease of the carp and the pike stock. The future fish stock management needs obviously regulations concerning selective fishing, replacement or other biomanipulatory techniques.
