ABSTRACT. The aim of this study was to describe the ichthyofauna composition of the Goczałkowice Dam Reservoir based on records in fisheries logs of commercial catches conducted in this basin over a 16-year period (1986-2001). The results indicate that the Goczałkowice Reservoir was managed appropriately during this period. The dominant species in the reservoir was bream at 49.74% of the overall biomass of all the fish caught. The second most common fish was a mix of small fish (31.62%). Evidence of the rational management of this basin is that 17% of the ichthyofauna are predacious fish, with pikeperch comprising 56% of all the predacious fish caught.
