The administration of these antioxidants did not influence the red blood count of rainbow trout, Salmo gairdneri Richardson, at body weights of 100 to 400g, reared in flow-through tanks at water temperatures of 7 to 13°C and in cage culture at water temperatures of 15 to 2O°C. In laboratory experiments at a water temperature of 14°C, the highest Kurasan dose increased the red blood cell (RBC) count insignificantly by 14% (1.06 vs 0.93 10121-1) after 80 days, haematocrit (PCV) was increased by 27% (0.410 vs 0.32511-1), and haemoglobin (Hb) by 16% (72 vs 62gl-1), This was seen in the cage culture experiment, but not in the experiments in the flow-through tanks. A trend of diminishing haematological parameters of the red blood count and total blood serum protein (TP) of the fish fed with BHT-stabilized diet was recorded only under laboratory conditions at the water temperature 9°C, The decline of RBC count in the experimental group with 0.04% BHT represented 14% (0.90 vs 1.05 10121-1), the decline in PCV amounted to 18% (0.328 vs 0.39811-1), Hb to 17% (57 vs 69g 1-1), and TP to 11% (39 vs 44g 1-1).
