Abstract: (5751 Views)
In order to evaluating of herbicide Butachlor sublethal effects on
Acipenser persicus fingerlings acute toxicity examination was
carried out statistically using OECD standard method in the
International Sturgeon Research Institute (Rasht-Iran). A total of
120 fish (with mean weight 10 ± 2 gr) were exposed to different
concentrations including 0 (control), 0.107, 0.215 and 0.322 mg/L
of butachlor. Mean lethal concentration of butachlor (LC50 96h)
determined 0.43 mg/L during 96 hours. Blood samples were
collected from caudal vein after 24 and 96 hours for biochemical
studies. The study for determining sublethal effects of butachlor on
liver tissue of Persian sturgeon carried out in laboratory conditions.
Results showed that cortisol and glucose levels increased
significantly (P<0.05) in different concentrations compared to
control. The histological study of liver tissues of the experimental
fish with the control groups showed clear changes including
congestion, hemorrhage, cytoplasm vacuolation and pycnosis of
nucleus, the cumulative haemosiderin in the melanomacrophage
cells and also necrosis and acidophilic changes of the cells. Results
indicated that butachlor at low level induced abnormal effects on
biophysiological structure of Acipenser persicus fingerlings.
