Data from a forty year period on catches and stocking from 25 selected lakes located in the Mrągowski Lake District were analyzed. The results of the analyses of catches and stocking indicate that, as a whole, the studied lakes underwent significant eutrophication and their environmental state declined during the studied period. These changes were manifested by changes in the quality of table fish catches and decreases in fishery effectiveness. The study results also indicated that positive changes occurred in the fishery of these lakes following the ownership transformation of the former State Fisheries Enterprises.
