Effect of Heavy Metal, Zinc and Carbamate Pesticide, Sevin on Haematological Parameters of Fish, Labeo Boga.

摘要

In the present study an attempt has been made to evaluate the combined effect of heavy metal, zinc and carbamate pesticide, sevin on the haematological parameters of the fish, Labeo boga for the experimental period of 63 and 60 days respectively. The studied parameters were Total erythrocyte count (TEC), Haemoglobin (Hb), Haematocrit (Hct), Mean corpuscular volume (MCV), Mean corpuscular haemoglobin (MCH), Mean corpuscular haemoglobin concentration (MCHC), Total leucocyte count (TLC) and differential leucocyte count (DLC). The mentioned parameters exhibited different responses on exposure to sevin and zinc. The alterations in these parameters have ultimately become the causative for affecting the general health status and hampering the entire metabolic machinery of the fish.
