Abstract- Nuvan, also scientifically known as Dichlorvos is chemically 2,2-dichlorovinyl dimethyl phosphate (DDVP) is an isomer of organophosphate pesticides used commonly to control the insect pest both in standing agricultural field & stored grain products. Nevertheless, the pesticide has adverse effect on the other beneficial organisms such as fishes present in the habitat. This investigation report is related with the toxic effect of Nuvan on the biochemical parameters of an air breathing fish Anabas testudineus commonly known as climbing perch having edible value. Different concentrations of Nuvan has been taken for examining the acute toxicity to a fresh water fish Anabas testudineus LC50 value calculated for the acute toxicity, which was 0.024 ml/L. Biochemical study of kidney Glycogen, Protein profile, Lipid profile, Cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) after 24hrs, 48hrs, 72hrs and 96 hrs exposure to lethal toxicity of Nuvan.
