要約

The species composition of macrozoobenthos and the quantitative indices of its development were studied in the rivers of the Danube and Dniester rivers basins within the territory of the Carpathians region. The biotopes suitable for the development and reproduction of brook trout in the studied rivers were revealed. The numbers of brook trout fry necessary to the reproduction of its natural populations were calculated on the basis of the obtained data. It was recommended to introduce annually 805 thousand specimens of brook trout fry with the body mass of the specimens of not less than 10 g.
