Abstract: The effect of phenol on haematological components of Indian major carps, Catla catla, Labeo rohita and Cirrhinus mrigala were observed.? After exposure to sublethal concentrations of 5.17 mg l^-1, 6.06 mg l^-1 and 6.99 mg l^-1, the number of red blood cells, haemoglobin content and packed cell volume all decreased but the glucose level increased.? The order of decrease in the haematological components of the three fish is in the order of Catla catla > Labeo rohita > Cirrhinus mrigala.
