Özet
The work was conducted to investigate the immune and antioxidant status and their-related gene expression in the muscle and liver of Black Sea salmon (Salmo labrax PALLAS 1814) juvenile fed with dietary fennel (Foeniculum vulgare) essential oil in different levels. Fish fed with diets have at different concentrations of fennel essential oil (EO) such as 50, 100, 200, and 400 mg kg-1. Fish with initial weights of 3.52 +/- 0.01 g were placed randomly 45 fish per 50-L fiberglass square tanks (15 in total). Experimental study was carried out as triplicate. Fish fed by hand 3% level of live weight with diets including fennel essential oil at 50, 100, 200 and 400 mg/kg, and control. At the end of 90-day experimental, there were no differences in superoxide dismutase (SOD) and catalase (CAT) in muscle. In liver, the highest glutathione peroxidase (GPx) activity was obtained in F400 group while the highest SOD and CAT were determined in F200 group. As the concentrations of fennel EO in diet increased, SOD activity in liver increased. The addition of fennel EO had no significant impacts on gene expression of CAT in liver and GPx in muscle and liver but decreased SOD expression was obtained in muscle. Besides, liver il1-b gene expression decreased significantly by administration of fennel EO. The fact that essential oils partially increase antioxidant enzyme activity has led to the conclusion that they may play a healing role in the antioxidant defense system. Hovewer, to understand the mechanisms related to the immune-antioxidant response of dietary fennel EO in Black Sea salmon, further research should be conducted on its expression and mode of action on the relevant genes.
