Effect of Cypermethrin on certain blood parameters of Catla catla exposed chronically

Alterations in blood serum parameters like enzymes, organic and inorganic constituents of Indian major carp, Catla catla after exposure to the sublethal concentration (1/10^th of 96hrs TLM) of cypermethrin, i.e., 0.00068 mg/l for 15 and 30 days time intervals have been studied. The 96hrs TLM value of cypermethrin for test fish was found to be 0.0068 mg/l. The activity of all the enzymes studied was found to be elevated significantly after both the time intervals. Change in serum organic constituents like blood urea and blood glucose show significant increase while total protein shows marked decrease. Inorganic constituents show high elevation due to the exposure.
