Growth characteristics and production efficiency of common carp fed high protein pelleted feed (42%) with 15.5 MJ/kg digestible energy and reared at three ambient temperatures (16°C, 24°C and 28°C) were studied under laboratory conditions during 33 days. Feed was manufactured by a well-known producer. It came out that fish ate less feed that recommended by the producer. Mass gain was highest at 24°C while FCR had highest values at 28°C (2.12) and lowest at 16°C (1.27). PER was most efficient at 16°C (1.86) and the least at 28°C (1.125). DGR was significantly higher at 24°C (0.011). SGR were also higher at 24°C (1.136 and 0.150 respectively). It was concluded that the formulation and/or ingredients of investigated feed was not appropriate for carp rearing.
