Author(s): U. D. Mestry and T. S. Bhosale

The present study was carried out to investigate Mercury induced Oxygen Consumption Rate (OCR) in a freshwater bivalve Lamellidens corrianus, a sentinel species in aquatic environment. The bivalves were exposedto acute and chronic dose of heavy metal, Mercury chloride. Oxygen Consumption rate for acute treat-ment was recorded in groups Lc0 and Lc50 concentration for 96 hour while chronic treatment was recorded for 7 day, 14 day and 21day from group Lc50/10thgroup. All results were compared with control groups of respective treatment. Our results showed that oxygen consumption rate was found to decrease with increased concentrationof mercury and exposure period.
