Abstract :

This study was conducted to investigate the effect of nonylphenol (NP) on the hematological parameters of rainbow trout, Oncorhynchus mykiss, after 3 and 7 days of exposure. The fish were intraperitoneally injected with 5 and 50 mg/kg doses of NP. The red blood cell count decreased significantly with both doses of NP at 3 days post injection. The white blood cell values showed a significant increase at 3 days post injection with 50 mg/kg NP, and this increase was also observed with 5 mg/kg NP at 7 days post injection. At 3 days post injection, hemoglobin was seen at significantly low levels, while the packed cell volume was at higher values with both doses of NP. No significant differences were observed in the erythrocyte sedimentation rate. The mean corpuscular volume showed significant increases at 3 days post injection, the mean corpuscular hemoglobin was observed to decrease with 5 mg/kg NP at 7 days post injection, and the mean corpuscular hemoglobin concentration exhibited significantly lower values at 3 days post injection. In conclusion, this study indicated that the treatment concentrations of NP induced distinct hematological changes in rainbow trout.
