Indian flying barb (Esomus danricus) was exposed to three sublethal concentrations of malathion (EC 50) for 28 days and intestinal histopathology was observed by light microscopy after staining with Haematoxylin-Eosine. In the exposed fishes, chronic inflammatory cell infiltration (lymphocyte) along with ulceration of mucosa and vacuolation was observed. Higher doses had severe effects.
