ABSTRACT

The effects of 0.0015 and 0.002 parts per million cypermethrin intoxication expose for 10/20 days was studied histopatholoically in different layers of the stomach of common carp fish Cyprinus carpio communis using Mallory Triple Staining. It was noticed that in anterior part of stomach (0.0015-ppm exposure) mucous cells lessened in number, link between serosa and longitudinal muscle lost and in posterior part, necrosis and bulging in longitudinal muscles were observed. With 0.002-ppm intoxication, the mucosal fold of anterior part of stomach fused at their tips, columnar epithelium contained many small spaces, and serosa broke off while in posterior part mucosal folds fused with each other. Mucous cells showed hyperplasia. Our results clearly indicated that the anomalies increase with the increase in concentration and duration of cypermethrin.

Keywords: necrosis, hyperplasia, mucous, fused, tips.
