Determination of LC_(50) 96h of dyazinon, hinosan and tilt for Acipenser nudiventris fingerlings

The toxic effects of agricultural pesticides Dyazinon, Hinosan and Tilt (Propiconazole) were studied on Acipenser nudiventris fingerlings (1-3g) in Spring 2005. We conducted our experiments in aquaria holding 20L water in static systems based on O.E.C.D method using five treatments, one control concentration and three replications. In each aquarium, ten individual Ship Sturgeon fingerlings were introduced, and water physical and chemical factors were controlled to be in the range pH=7-8, TH>400mg/l (CaCO _(3)) as for the water used for culture, and DO=80% and temperature was kept between 24 ±1°C. Our results for the LC _(50) value of Dyazinon, Hinosan and Tilt in 96 hours were 0.36, 0.28 and 3.9mg/l in the fish fingerlings. We also determined the maximum allowable concentration value of the toxins at 0.036, 0.028 and 0.39, respectively.
