Fatty liver disease (FLD) is the most common cause of chronic liver disease in fish in the whole world. In the present study, the hepatoprotective effect of preparatıon Vitasil content extract of Milk thistle (Silybum marianum) was evaluated by ultrasound examination of liver and measuring biochemical parameters of liver function. 240 carp were randomly assigned into three groups (two experimental and one control) with different diet for each of them in order to induce experimental obesity and liver dystrophy for period of 9 months. Blood samples were taken every 3 months during the study to evaluate AST, ALT, total protein and albumin concentrations. While at the same time six fish from each of the groups were anesthetized and ultrasound scanned. The obtained results of the study proved the protective effect of preparation Vitasil on liver tissue and function.
