Debasish Bhattacharjee & Suchismita Das

Our study aims to assess the pathological alterations in the intestinal issues of freshwater teleost, Channa punctata, at weekly exposure durations, for 21 days. A sublethal dose of 0.03 g L-1 was selected and test and control fish were maintained for 21 days under laboratory condition. Light microscopic study, with Haematoxylin and Eosin stain, was used to detect the intestinal pathology. The study revealed structural damages and a direct correlation between pesticide exposure and severity of effects. Keywords
