Abstract The toxicity test of fenvalerate were conducted to fresh water fishes Labeo rohita (Hamilton), Catla catla (Hamilton), Cirrhinus mrigala (Hamilton), Aplocheilus punchex (Hamilton) and Ctenopharygodon idellus (Valenciennes). The static and continuous flow through tests were employed to determine the lethal concentration (LC50) for 24h, 48h and 96h to the test fish. It was observed that Cirrhinus mrigala is more sensitive to this pesticide followed by Applochielus punchex, Lebeo rohita, Catla catla and Ctenopharyngodon idellus. The residue analysis for qualitative confirmation was done by thin layer chromatography (TLC) to assess the deposition of pesticide in different tissues of fishes. The quantitative study of accumulation in the whole body tissue was done by Gas liquid chromatography (GLC). The quantitative residues confirm the toxic action.
