Haematological alterations in a fresh water fish Anabas testudineus under cypermethrin exposure


Anupama and Amit Kumar Jha


Cypermethrin, a synthetic pyrethroid is a broad spectrum insecticide used extensively in households and agriculture fields to control the pests. Use of insecticides in agriculture to prevent the crop damage from pests come with a significant cost as they reach to the aquatic systems through irrigation and rain and deteriorates the water quality. It adversely affects the non-target organisms including fishes of the fresh water ecosystem. Pyrethroid insecticide cypermethrin was used for this investigation to study the alterations in blood biochemical of a fresh water fish Anabas testudineus. Acute toxicity of cypermethrin to the fish was determined for 24, 48, 72 and 96 hours. The LC50 value was measured 0.15 ppm, 0.20 ppm, 0.2 ppm and 0.30 ppm respectively by the regression equation. The sublethal concentration determined was 0.106 ppm. After exposure period of 30 days significant changes in the blood biochemical level was reported during the present study. Blood glucose, serum protein and serum cholesterol of cypermethrin treated fish exhibited hyperglycaemic, hypoproteinemic and hypercholesterolemic response. The present investigation come to a conclusion that cypermethrin alters the blood biochemistry of Anabas testudineus and hence, affects the fish health.
