Alterations in the Hematological and Biochemical Parameters and Plasma Ion Concentrations of Common Carp, (Cyprinus carpio L., 1758) after Short Term Exposure to Sub-lethal Concentrations of Lead

In this study the 96 h acute toxicity (LC50) of lead (Pb) for common carp (Cyprinus carpi L, 1758) was investigated and the fish was exposed to sub-lethal concentration of lead for 96 h. The hematological and biochemical parameters (red blood cell count, hemoglobin, hematocrit, white blood cell count and leucocrit) and plasma glucose, lactate and total protein levels and plasma ion concentrations of fish were investigated and compared to control fish. It was found that lead had significant effects on red blood cell count, hemoglobin levels, plasma glucose and lactate levels and plasma ions, while hematocrit, white blood cell count, leuocrit and plasma total protein levels remained unchanged.
