Nuvan and Dimecron is an organophosphorus pesticides widely used in agriculture ,animal husbandry,horticulture,food storage and even to control fleas on domestic pets.In the salmon farming industry it is used to control sea lice. Both the pesticides attract an important enzymes in the nervous system of insects and human.People can get sick from breathing too much pesticides vapor in the air.The pesticides can cause more serious nervous system symptoms if exposure continuous. Diffrent methods employed for the determination of acute toxicity of cat fish Clarias batrachus.An average 96 hrs LC 50 was found to be 1.66+-0.36 mg/lwith 3.14+-0.025 mg/l as upper and 2.16+-0.24 mg/las lower 95% confidence limits for Nuvan and 5.46+-0.13mg/l with 4.55+-0.11mg/l as upper and 5.04+-14 as lower 95% confidence limit for Dimecron. Different methods used for determination of LC50 value gave almost same results.Behaviour of fishes during experiment also observed showed erratic and jurky movements secreting mucous and increased opercular movements were exhibit by fish.
