ALTERNATION IN SOME HAEMATOLOGICAL PARAMETERS OF CHANNA PUNCTATUS ON EXPOSURE TO NICKEL

Ms. Smita Bhoi, Dr. Aliva Patnaik, Rajesh Behera

Abstract :

Fish is one of the major sources of protein which meets the demand for higher food production and thus aquaculture plays an important role in food production. But the addition of untreated industrial, agricultural and domestic wastes to the water bodies introduces stress to the aquatic organisms including fishes. Among the pollutants the heavy metal introduced into water bodies have detrimental effect on the physiological characters of the fishes. In the present study effect of nickel has been studied on Channa punctatus. The results obtained during the present investigation shows that there was significant changes in blood parameters on exposure to acute and chronic sub-lethal concentration of nickel. The haemoglobin percentage and the haematocrit percentage showed a steady decrease with an increase in the concentration of nickel. The total WBC count showed slight increase at lower concentration and then decreased drastically. The MCV, MCH and MCHC in the present investigation decreased steadily with an increase in the concentration of nickel.
