| Diazinon is commonly used for pest control in the agricultural fields surrounding freshwater reservoirs. So this study was conducted to determine the sub-lethal toxicity of this organophosphorous pesticide, contaminating aquatic ecosystems as a pollutant, and its effects on histopathology of testis and ovaries common carp, Cyprinus carpio. Diazinon was applied at sub-lethal concentrations of 60 µg/l and 120 µg/l at 30 days. The histhopathological effects of diazinon on testis and ovaries tissues of Cyprinus carpio were determined by light microscopy. In this study, negative effect of diazinon on the testicular and ovarian tissues of common carp is investigated. The degeneration of seminiferous tubules, atrophy and vacuolation in testicular tissues are most important changes observed in treated fish by diazinon. The atretic oocyte and degenerative cell phagocytize in ovarian tissues of fish exposed to diazinon were seen. Histopathological changes were significantly increased related with increasing diazinon concentrations. |
