The ichthyofauna composition of the Goczalkowice Dam Reservoir (Poland) based on records in fisheries logs of commercial catches conducted in this basin over a 16-year period (1986-01) was described. The results indicate that the Goczalkowice Reservoir was managed appropriately during this period. The dominant species in the reservoir was bream at 49.74 percent of the overall biomass of all the fish caught. The second most common fish was a mix of small fish (31.62 percent). Evidence of the rational management of this basin is that 17 percent of the ichthyofauna are predacious fish, with pikeperch comprising 56 percent of all the predacious fish caught
