Abstract
The results obtained in cage rearing of carp (K2-K3) in cooling waters of the “Dolna Odra” power station (near Gryfino) are presented. The cooling water temperature ranged within 18.4-31.7 °C; oxygen saturation did not fall below 80%; pH ranged from 7.3 to 8.3. The fishes were kept in culture during 130 days (May 20-October 1, 1975), in densities of 75 and 110 individuals/m3 of water. The fishes were fed on a carp granulate and a piglet dry granulated food. It has been found that the densities applied exerted no influence upon the fish growth rate, where as the various foods used resulted in different rearing and economic effects.
