Effect of chlorpyrifos on protein and carbohydrate content of Heteropneustes fossilis (Bloch, 1794)


Author(s): Sneha Verma and Anurag Rawat

Abstract: Organophosphorus pesticides are used in the agricultural area due to their rapid biodegradability and non-persistent nature to control pests but their broad spectrum of harmful effects extends far beyond the pest. The objective of this research was to investigate the effect of sub-lethal chlorpyrifos effect on ovarian protein and carbohydrate content of the freshwater catfish “Heteropneustes fossilis”. LC10, LC25 and LC50 value of chlorpyrifos were calculated for 24, 48, 72 and 96 hr by probit analysis (Finney, 1971). The LC10, LC25 and LC50 value for 24 hr were 9.79, 21.59 and 51.95µl/l, and 3.3, 7.54 and 18.91µl/l for 48 hr, and for 72 hr: 0.85, 2.39 and7.47µl/l. The 96 hr LC10, LC25 and LC50 value were 0.12, 0.55 and 4.64µl/l respectively. The result showed that CPF significantly (p<0.05) decreased the ovarian protein and carbohydrate concentration. Therefore, it may be concluded that CPF is highly toxic to aquatic organism.
