Investigation some haematological indices of Persian sturgeon (Acipenser persicus) exposed with nonylphenol

The purpose of the present study was to investigate the effect of nonylphenol as a monomer of a pollutant on Persian sturgeon (Acipenser persicus) hematological parameters changes. Injections of different treatments of 1.10 and 100 mg/kg body weight of fish nonylphenol were carried out in sample fish with a mean weight of 250 grams and injections repeated three times in three consecutive weeks. After 72 hours of the last injection, taking blood samples, some hematological indices including white and red blood cells, differential white blood cell count, and secondary hematologic factors were analyzed. After counting, the low levels of hemoglobin, hematocrit and red blood cells in the treated group compared to the control group were considered the reason for exposing the animal to the stress, because diminished hemoglobin protein, red blood cell count and hematocrit indicate the condition of anemia under conditions of exposure to the contaminating substance. The total number of white blood cells in the treatments increased compared with the control. The differential count of eosinophil white blood cells in the treatments of 10 and 100 mg nonylphenol per kg body weight of fish showed a significant increase and also neutrophil significantly increased in all treatments. Lymphocyte significantly increased in treatments of 10 and 100 mg nonylphenol per kg body weight of fish, but there was no significant change in monocyte count compared to the control group. Secondary hematologic indices (MEH, MEV and MEHC) have significant changes in direction were observed, consistent with an increase in white blood cells numbers.
