The average growth of bream body length, average annual body length, and body weight gains were determined by taking appropriate measurements and weighing the fish. The study involved bream individuals collected from the Solina (447 fishes), Tresna (190), and Rożnów (804) dam reservoirs. The fish age in the reservoirs sampled ranged within 4–15, 3–13, and 3–10 years, respectively. The Rożnów bream was distinct in their highest growth rate, followed by the fish collected in the Tresna and in the Solina. The 10-yr-old bream in the Solina, Tresna, and Rożnów were characterised by the average body length 30.8, 31.9, and 41.5 cm, respectively. The high growth rate of the Rożnów bream was probably a result of, i.a., repeated net fishing operations in the past, such operations being recommended as a basic measure in the management of fishing and angling in all dam reservoirs.
