This sample is highly representative of all the fisheries conducted in this basin category in Poland and in other East-Central European regions. The following questions referring to the impact of climate change were defined and analyzed based on the answers obtained from the questionnaires: survival of hatchlings, fry, and adult fish; the spawning success of selected fish species; selected hydrological and biological reservoir parameters, the possibility of using and the effectiveness of fishing gears; the length of the recreational fishing season; the size of recreational and commercial fisheries catches of different fish species. Information regarding the impact of reservoirs on fish migrations was also obtained.</p></abstract>
