Toxicological effect of pulp and papermill effuent in the fish, Oreochromis mossambicus was investigated in the present study. Pulp and papermill effluent discharged from Hindustan News Print LTD, Peruva, Kottayam, Kerala were collected and adult fish of size 15 ± 2 g were exposed to a sublethal concentrations (1/5th and 1/10th LC50 value) of the effluent for a period of 10, 20 and 30 days. The treated fish were compared with the control group for the histological alterations in the blood smear. The study revealed marked changes in the blood tissues of the effluent treated fish.
