Abstract :
This study examined the histopathological effects of anesthetic 2-phenoxy ethanol on liver of Barbus grypus. In this study, a total of 30 Barbus grypus with sizes of 100 ± 2 g were selected. Water temperature with an average of 20°C. Fish were exposed to anesthetic 2-phenoxy ethanol with ascending concentrations of 400, 600 and 700 mg/l for 90 second. Then first stage was"an hour" and the second was "three days after anesthesia" liver biopsy was taken samples were stained at 5-micron sections with hematoxylin – eosin method. Microscopic observations showed the effects of 2-phenoxyethanol on the liver at the dose of 700 mg/l create vacuolization, enlargement offat cells and dilatation of the hepatic sinusoids. At doses of 400 and 600 mg/l, this effect was less.
