Abstract

 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.
