Chemical burden has been increased on agricultural land throughout the world due industrialization Objective: To observe the proximal characteristics of a very famous fresh water fish commonly called as rohu(Labeorohita) with acute and chronic exposure of pesticide,Chlorpyrifos (CPF).Method:To check acute exposure, concentrations of CPF used include, 0, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.02, 0.03, 0.04 and 0.05 mg/L for 96 hrs in glass aquaria. For Labeorohita, 96 hrs LC50 value of CPF was found 0.01 mg/L. To study chronic exposure on Labeorohita, 1/3rd, 1/5th, 1/7th and 1/9th of LC50 for 30 days concentrations were used. At the end of the experiment, samples were collected for proximal analysis. The parameters included moisture, ash, lipids and protein Results:The exposure of CPF reduced the protein content. Moreover, there was reduction in ash and moisture contents. Conclusions: It is therefore concluded that CPF adversely affects the major organs of the fish Labeorohita
