Abstract
Pesticide, dimethoate as a pollutant, was used to see its effect on oxygen consumption of freshwater fish, Arias dussumieri. The fish Arias dussumieri was exposed to lethal (5.99 ppm) and sublethal (0.599 ppm) concentration of dimethoate for 96 hours and 60 days. The rate of oxygen consumption was found to be increased initially upto the 48 hours, then decreased upto end of the experiment. Similarly during chronic treatment, the rate of oxygen consumption remained unaltered at first day of exposure, increased after 7th day and continued till 30 days, then decreased upto the end of the experiment.
