Studies on Metallic Salt Intoxication on Blood Parameters of Two Fishes, Channa gachua and Channa reba

The values of haematocrit, haemoglobin and erythrocytes percentage of untreated Channa gachua in 24, 48, 72 and 96 hr of exposure were in the range of 42.38 to 42.79; 13.95 to 14.35; 3.14 to 3.52, and that of Channa reba, in the range of 42.63 to 43.75; 13.95 to 14.72 and 3.18 to 3.65 respectively. After treatment with two metallic salts i.e., CuSO₄ and K₂Cr₂O₇ in different concentrations at these exposures these parameters exhibited a of range of 40.12 to 41.2 and 40.25 to 42.25 (haematocrit); 14.12 to 14.84 and 13.89 to 14.25 (haemoglobin) and 3.06 to 3.26 and 3.05 to 3.22 (erythrocytes) in case of C. gachua while the values were 41.85 to 42.00 and 41.25 to 42.87 (haematocrit); 14.12 to 14.65 and 14.01 to 14.65 (haemoglobin) and 3.10 to 3.55 and 3.12 to 3.62 (erythrocytes) respectively in case of C. reba.
