While a significant increase was observed in values of WBC, neutrophil, eosinophil, monocyte, MCV, MCH and thrombocyte depending of dose groups and time periods, a significant decrease was determined in values of lymphocyte, erythrocyte, haemoglobin and hematocrit. But we couldn't observe a significant changes in values of basophil and MCHC. When the dose amount and exposure time were increased, the blood abnormalities became clearer. We can say that the fish have a macrocytic anaemia because of the increase in their mean cell volume (MCV), besides the decrease in their red blood cell (RBC), haemoglobin (Hb) and hematocrit (PCV).eninfo:eu-repo/semantics/closedAccessBlood parametersCopper nitrateOncorhynchus mykissArticle7477978012-s2.0-6444243696Q3
