Effect of aluminum exposure on some blood parameters in the Tilapia zillii fish

Abstract

The present study discusses the effect of aluminum chloride of the freshwater fish Tilapia Zillii that exposed to different concentrations of 25, 50, and 100 mg aluminum per liter of acidic soft water (PH 6.0). The hematological changes based on the examination of some blood variables during the 24, 48, and 96 hours of exposures have been reported. The hematological parameters determined were: total erythrocytes count (RBC), hematocrit (HCT), and mean corpuscular volume (MCV). Results showed statistically differences in RBC count and HCT were significantly higher when compared with control groups, while there was significant reduction in mean corpuscular count. Changes increased with increase in concentration of aluminum and time of exposure. Observation of blood parameters allows the most rapid detection of changes in fish after the exposure to xenobiotics.
