The experiment was carried out in spring (2004) on 300 carp divided into two feeding groups. Group I was fed high-fat feed, whereas group II high-carbohydrate feed. After 7 weeks, fish blood and livers were collected for further analyses. Significantly higher body weight gains were found in the fish fed high-fat feed as well as significant increase of haemoglobin (Hb) concentration in the blood of both feeding groups, which was accompanied by the increase of haematocrit (Ht) index. The concentrations of lipid peroxidation products (MDA) was increased. The observed MDA values and reduced glutathione (GSH) concentration in the fish liver may indicate enhanced peroxidation processes in the organisms of the fish from both experimental groups, caused by their intensive feeding with extruded feeds. The peroxidation processes were more intensive in fish fed high-fat feeds
