Assessment of toxicity of lambda-cyhalothrin for Heteropneustes fossilis and Channa punctatus

Insecticidal use in agriculture gained momentum around the mid-twentieth century. Fungicides are also used in agriculture for the prevention of fungal infection in seed grain. Later these compounds discharge in nearby water bodies and consumed by fishes and other aquatic life. These fat-soluble contaminants concentrate in the adipose tissue of fishes by bioaccumulation and biomagnification. The present study helps in assessment of toxicity of lambda-cyhalothrin, a pyrethroid to fishes Heteropneustes fossilis and Channa punctatus.
