| description | Effects of different concentrations of Diazinon on Roach Torkemani (Rutilus rutilus caspius) fries
supplied from Ghareh-Soo Fishery Research Station was studied in Gorgan University of Agricultural
Science and Natural Resources in 2009 to determine 50% lethal concentration (LC50) for the fish
within 96 hours. In this study, 126 Roach fries with mean weight of 3 grams were used. Tests were
performed statically based on instructions of O.E.C.D under fixed water quality conditions at the
temperature 24±1 and pH 8-8.5 in a completely random trial with five concentrations treatments of
Diazinon (5, 5.95, 7.07, 8.48 and 10mg/l) in three replications and the means were compared using
Duncan test at 5% significance level. The results indicated that at the end of 96-hour test, LC50 was
7.88mg/l. In this test, clinical signs such as hunched spinal column, thrilling, clot in caudal fin and
head, and irregular swimming were observed in the studied fish specimens. In hematological
examination, there was a remarkable decrease in percent of hematocrit between concentrations of 5
and 5.95mg/l of Diazinon. By increasing the concentration of this poison, the decrease became slower.
Furthermore, there was a significant difference in percent of hematocrit between control group and
LC50 group, with mean amounts of 36 and 27%, respectively. Based on the results, Diazinon was
classified as toxic pesticide for Roach Torkemani. |
