Effects of Cypermethrin on Haematological markers in Wallago attu

Wallago attu was exposed to five different concentrations of cypermethrin for 30 days and found a remarkable change in haemoglobin, TLC, PCV and TEC values. A surging rise was noticed in all the four parameters on exposure to the different concentration of cypermethrin on day 1 but there was a slight reduction in the haemoglobin content, PCV and TEC with a slight rise in TLC after few days. Wallago attu exposed to cypermethrin showed an increase in blood glucose level. Cypermethrin has potent piscicidal activity against Wallago attu and adversely affects.
