Abstract: (4062 Views)

The present study aimed to investigate the effects of different concentrations of effluent from urban wastewater treatment plants on blood biochemical factors and histopathology of the common carp (Cyprinus carpio) in a culture system. The experiment was conducted as five treatments, 0% (control), 25%, 50%, 75 % and 100% wastewater concentrations in triplicates. , Fish were fed with a commercial pellet (Fradaneh Co. Shahrekord) for a period two months and the rate of mortality was recorded. According to the results, with increasing the wastewater concentrations, blood cortisol levels were increased significantly (P<0.05). Moreover, the white blood cells (WBC), red blood cell (RBC), hematocrit (HCT), hemoglobin (Hb) and mean corpuscular volume (MCV) were significantly (P<0.05) increased in blood. Histological results demonstrated that wastewater could cause reactions in both liver and gill due to stress condition, however serious damage was not found in any of the tissues. Considering the issues in common carp culture management in waste water, and according to the results of fish mortality, cortisol stress hormone concentrations, hematological indices and histological findings in 75% and 100% wastewater treatments, urban 50% wastewater mixed by 50% cultural water is recommended for this fish culture .
