Abstract

Haematological changes determined in the fish Cyprinus carpio exposed to Deltamethrin technical grade and 11% EC both in lethal as well as in sublethal concentrations are reported. The blood parameters of Erythrocytes (RBC), Leucocytes (WBC), Haemoglobin (Hb), Hematocrit values (Ht), mean corpuscular volume (MCV), Mean corpuscular Haemoglobin (MCH), Mean corpuscular concentrations (MCMC) that determined by standard protocols are reported. The changes as effects when control are reported as: (a) RBC decreased (b) WBC increased (c) HB, Hb/MCV decreased, (except for lethal technical grade), (d) MCH and MCHC increased and that are going to be discussed with the earlier reports to elicit the information of the possible ways of explanation for such changes.
