Production effectiveness of rapeseed stamping in the common carp fodder was attested in the controlled conditions of recirculation system with the absence of natural food. 4 isonitrogenous (31.5% NS) and isoenergetic (17.3 MJ GE/kg, resp. 13.5 MJ DE/kg) diet with different (35 and 40%) unmodified (URS) and technologically modified (MRS) rapeseed expeller ratio were tested. During the sixty-day feeding trial, beneficial production effect of diet with modified stamping was proved. Diet MRS fish were characterized by significantly faster length growth. In comparison with fry of MRS variant, they have reached highly significantly the higher values of broad backedness index and significantly higher values of body width. Significant values were not detected by individual weight and HSI. Except the haematocrit value, there were no hematologic and biochemical indices influenced by feed type. Higher content of fat in the URS was shown at fish variant URS/40 by higher fat deposition in hepatopancreas (averagely 30.31%), without statistically significant difference compared to other variants.
