Effects of Copper sulfate and formalin on hematological parameters of Barbus sharpeyi

In the present study, hematological responses in 160 Barbus sharpeyi (Bennie) after one week exposure to 1.75, 2.33, 3.5, 4.37 and 8.75 ppm of formaldehyde and 0.5, 1, 2, 5 and 10 ppm of copper sulfate (CS) in comparison with control group was evaluated. In copper sulfate treatment, RBC and WBC number, Lymphocytes% and monocytes%, Hematocrit and Hemoglobin (Hb) decreased after exposure to higher concentrations while Neutrophils%, mean cell volume and mean cell hemoglobin concentration, increased in higher concentrations (P<0.05). In formaldehyde treatments the parameters altered at higher concentrations in the same pattern as CS but Monocytes% and Hb tend to increase significantly (P<0.05).
