Fingerlings of Catla catla, Indian major carp introduced in to two toxicant ie., pesticides Chlorpyrifos and fungicide Hexaconazole for 24 hrs in laboratory condition to analyze the enzyme activity SDH, LDH and ALP in the brain tissue fishes. SDH and ALP declined in Chlorpyrifos showed mean value 3.14 ± 0.03 MIU/min/mg and 5.71±0.01μg/ PNPP to PNP/100 mg than the fungicide (3.84±0.01 MIU/min/mg and 5.34±0.02 μg/ PNPP to PNP/100 mg) and control(4.75±0.03 MIU/min/mg and 7.04±0.13). LDH elevated in both the group particularly in Chlorpyrifos (6.57 ± 0.12 μg/100mg) than control (7.04±0.13 μg/100mg), therefore Chlorpyrifos showed maximum impact on fish brain than Hexaconazole.
