Effects of Chlorpyrifos on proximal characteristics of Labeo rohita fish in acute and chronic exposure
Effects of Chlorpyrifos on proximal characteristics of Labeo rohita
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
