Hematological indices are gaining general acceptance as valuable tools in monitoring various aspects the health of fish exposed to contaminants. In this work, some effects of mercuric chloride on hematological parameters by the fresh water fish labeo rohita. The acute toxicity value (96 h LC50) of mercuric chloride was found to be 0.25 mgl-1 calculated by Finney?s probit method. Fishes were exposed to sublethal concentration of 1/10th 96 h LC50 (0.025 mgl-1) for the period of 5,10 and 15days.The present study was revealed significant decrease (P<0.05) for RBC count, HB levels, andpacked cell volume (PCV) than control group. In contrast, there was a significant increase in WBC count, Glucose, alanine transaminase(ALT), mean corpuscular volume (MCV), and total leucocyte count(TLC) in the mercuric chloride-treated group. But the total protein(TP), mean cell haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) values were significant with control group. So, estimation of these indices, could provide a useful indicator of pollution of water bodies. The present finding clearly indicating of mercuric chloride toxicity is strong influence in aquatic environment on the hematological parameters in the fresh water fish Labeo rohita.
