STUDIES ON ACUTE AND BEHAVIOURAL TOXICITY OF TRIAZOPHOS ON FRESHWATER FISH CYPRINUS CARPIO
Pattar Rm, David M
Abstract :
The present study was undertaken to evaluate the median lethal concentration (LC50), and changes in behavioural responses caused by commercial formulations of triazophos on freshwater fish Cyprinus carpio. The LC50 value was recorded to be 1.5mg/L and changes in behavioural responses were studied at sublethal concentration of 0.3mg/L (1/5th), for a duration of 1, 10, 20 and 30 days, which revealed findings like, loss of fright response in addition to changes in swimming pattern that comprised of partial jerks, sinking at the bottom of the tank and whirling cork like movements. These changes were identified to be duration dependent thereby acknowledging the direct cause of damage due to triazophos. Based on the outcome of the present study, it is recommended that care must be taken when triazophos is used at agricultural sites especially nearby the aquatic ecosystems.
