Haematological Parameters As An Index Ofimmune Response In The Heavy Metal Toxicantrninduced Fish, Catla Catla And Labeo Rohita

摘要

Haematological parameters as indications of immune response have been investigated in Catla cutla and Labeo rohita which were exposed to sub-lethal doses of cadmiun chloride and mercuric chloride, respectively. The per cent decrease in haemoglobin and erythrocytes was observed to be 9.59 and 38.2 in C. catla and that in L. rohita was 14 and 47.32. The number of granulocytes, lymphocytes and monocytes showed significant increase ranging between 38.89 and 42.98 % in C. catla while it was between 42.2 and 44.89 in L rohita. In C. catla the blood urea levels decreased by 10 per cent but in L. rohita, it showed an increase by 36.8 per cent. Serum creatinine and serum calcium levels showed significant increase (C. catla: 50 & 30.98 %L. rohita: 150 &45%)in both the fish.
