Effect of Copper Toxicity on Hematological Parameters to Fresh Water Fish Cyprinus Carpio(Common Carp)

Abstract

The present study was to evaluate the toxicity of copper in the blood cells of fresh water fish Cyprinus carpio. Ingestion of copper compounds cause anemia and other blood cell abnormalities, may produce systemic toxic effects to the kidney and liver and central nervous system excitation followed by depression. Causes respiratory tract irritation with possible burns. Chronic: Prolonged or repeated eye contact may cause conjunctivitis. Table 2 and Fig.1 Reveal the changes in red blood cell count of the blood of fish Cyprinus carpio exposed to sublethal concentration of copper exposed for 35 days. The RBC count was decreased throughout the study period when compared to the control showing a minimum percent decrease of - 2.22 at the end of 7 th day and a maximum percent decrease of 18.36 at the end of 35 th day. Decrease in RBC count in copper exposed for 7 th , 14 th , 21 st , 28 th , and 35 th days, the percent observed was -2.22, -6.52, -10.63, -
