IMPACT OF PYRETHROID INSECTICIDES ON THE HAEMATOLOGY OF CHANNA PUNCTATA (BLOCH)

Abstract

Noxious effect of pesticides is a matter of worldwide concern in the edible fishes. Present study was planned to monitor the Pyrethroid insecticides induced toxicity. To determine the extent of Pyrethroid toxicity in the exposed Channa punctata, haematological evaluation of blood was done. A sublethal concentration of the pyrethroid trioxide was given for 30 days. Fish were fed on special diet at the rate of 2% body weight. The hematological parameters such as TEC, Hb and PCV were significantly increased whereas ESR, WBC, MCV, MCH and MCHC values were decreased significantly in pyrethroid exposed fish. However, significant changes were observed only after 20 days (p
