Abstract
Part of the lower Drawa River between Dubie Lake and the Płociczna River mouth, stretching for a distance of 38.8 km, belongs to the Drawieński National Park, established in 1990. Electrofishing conducted on the 8 river stretches within the park limits yielded a total of 26 fish species and one cyclostomate species. The leading species appeared to be the roach, with the domination level reaching 56.16%. The other abundant species were: burbot (D = 7.81%), silver bream (D = 6.88%), and perch (D = 5.95%). The remaining species occurred in smaller numbers. The Drawa River within the Park limits is inhabited by 3 species of the family Cyprinidae: minnow-Phoxinus phoxinus, schneider-Alburnoides bipunctatus, and bitterling-Rhodeus sericeus amarus, all under strict protection and one cyclostomate species of the family Petromyzonidae-river lamprey-Lampetra fluviatilis, protected at the stage of larval development.
