Effect of Environmental Stresses on Lipid and and Haematological Profiles of the Air Breathing Catfish Clarias batrachus (Linn.)

Fishes adopt themselves to some extent when natural waters have high BOD, heavy metals and ozone contamination. The present work studied the effects of hypoxia, anoxia, ozone, copper sulphate and a combination of copper sulphate + ozone on the lipid and hematological profiles of  Clarias batrachus. In case of lipid profile, total cholesterol level (195.5 ± 1.5) was highest in normal condition, triglyceride (204 ± 3.162), HDL (38 ± 1.224) and VLDL (40.75 ± 1.478) in 2 hour hypoxia, and LDL (129 ± 2.236) in copper sulphate + ozone treated condition. Analysis of blood samples showed elevation Hemoglobin level (9.7 ± 0.070) was highest in 4 hour hypoxia condition, RBC count ( 3 ± .070) and glucose level (186.75 ± 1.478)  in 2 hour hypoxia , PCV percentage (28 ± 0.707) in anoxia , and total protein in normal (6 ± 0.070) and 2 hour hypoxia (6 ± 0.141) conditions.
