INVESTIGATION OF ACUTE TOXICITY OF SYNTHETIC PYRETHROID FENVALERATE IN FISH CYPRINUS CARPIOV. RAJA, B. VELMURUGAN, M. SELVANAYAGAM AND T. AMBROSE
Acute toxicity of synthetic pyrethroid fenvalerate in fish common carp Cyprinus carpio investigated in the present study. The static renewal test method of acute toxicity was used. The experiments were repeated 3 times and the 96-h LC50 was determined for the Cyprinus carpio. The data obtained from the acute toxicity test were evaluated using the probit analysis statistical method, developed by USEPA. The 96-h LC50 value for fenvalerate in fish Cyprinus carpio was found to be 3.059 ppb. Fenvalerate was found to be more toxic to the fish Cyprinus carpio. Behavioural changes were studied during the exposure period.
