The present research was performed to determine lethal concentrations of diazinon for the Caspian vimba, Vimba vimba persa. Fish samples (50 ± 5 g) collected from Sefidroud river were acclimatized for 5 days and exposed to 5 concentrations of diazinon, 0.07, 0.08, 0.1, 0.13 and 0.16 mg/l (with three replicates) and lethal concentrations (LC) LC1, LC10, LC30, LC50, LC70, LC90 and LC99 for 24, 48, 72 and 96 h were determined using a probit analysis. The results indicated that the 96 h LC50 value of diazinon for Caspian Vimba was 0.08 mg/l.
