Effect Of Deltamethrin In The Indian Major Carp Ciprinus Carpio With Special Reference To Cholinergic Activities

Effect of deltamethrin in the Indian major carp Ciprinus carpio with special reference to cholinergic activity was studied. The fishes were randomly divided into 3 groups having 6 in each group: (1) Control (2) Deltamethrin-induced toxic group (5ppm) (3) Deltamethrin-induced toxic group (10 ppm). Deltamethrin-induced toxic groups increased the Acetylcholine (ACh) and decreased the levels Acetyl cholinesterase (AChE) in Brain of fish. Exposure of fishes to 5ppm and 10ppm sub lethal concentrations of deltamethrin caused rigorous changes in the acetyl cholinesterase activity. Utmost activity was observed in the fish exposed to 10ppm sub lethal concentration.
