effect of oxadiazon herbicide (ronstar) on some blood indices in dices in silver carp (hypophthalmicthys molitrix).

oxadiazon is a selective herbicide used to control weeds in agriculture. the purpose of this study was to investigate the effects of oxadiazine herbicides on fish phytophagous fish indexes. after adaptation of 270 species of phytophagous fish with an average length of 1 to 13 cm and an average weight of 50 to 100 grams to reservoirs each having a capacity of 12 liters they were placed. the concentrations of each reservoir were 5 and 10 mg / l, respectively, of oxadiazone. dandruff blood samples were taken from 3 treatments (each treatment with 3 replicates) completely randomly every 12 hours to 72 hours. the results showed that hematocrit and hemoglobin and red blood cells were significantly different in other treatments (p <0.05).there was no significant difference between mean blood hemoglobin concentration and mean blood hemoglobin between control and treatments (p>0/05). there was a significant difference in white blood cell count, eosinophil count, lymphocyte, monocyte, neutrophil in control treatment with other treatments p<0/05. one of the reasons for the changes in some of the blood indices is due to a disruption of the hematopoietic process of the fish.
