The present study aims to assess the histological changes in the intestine of fish Ctenopharyngodon idella exposed to the herbicide Glyphosate (Roundup). Glyphosate is a broad-spectrum herbicide used to control a wide variety of weeds and plants. The mode of action of glyphosate is to prevent an enzyme pathway, and preventing plants from synthesizing three aromatic amino acids. Healthy fishes irrespective of sex of uniform body weight (30 ± 5 gm.) and body length (12 ± 1.4 cm) were exposed to various concentrations (0.001%, 0.003%, 0.005% and 0.007%) to determine LC 50 96 hrs and was calculated as 0.003%. Histopathological study conducted on fish exposed to sub-lethal concentration (1/2th) for a period of 10 days. The pathological changes observed in the fishes are ulceration (UE) of gastric epithelium and inflammatory cell infiltration (IN).
