Abstract: The influence of dietary phenol on immunity, and hormonal profile was studied in catfish. The results revealed that, treatment of Catfish (Clarias gariepinus) with 12mg/l phenol for 3 months decreased IgM, Insulin, Thyroxin, however there was elevation in cortisol hormone level. Phenol may induce an immunosuppressive effect on humoral immune response of African Catfish which was suggested by reduction of immunoglobulin.
