In the present investigation effect of gamma radiation on certain tissues (kidney, stomach and gills) of Heteropneustes fossilis Bloch, an Indian Cat fish, were studied. The fish were irradiated with 10 Gy of gamma radiations at the dose rate of 1.60 Gy/minute from a 6co source. Five fish were autopsied at each post-irradiation time of 1.2.3, 7.15 and 30 days. Radiation induced histopathology was observed in all the tissues studied. The radiolesions appeared on day-1 after exposure which became exaggerated on day-2 and 3. Signs of recovery were noticed on day - 7 which progressed on day-15 and normal histology was observed on day-30.
