Özet

In this study, anesthetic effects of lavender (Lavandula angustofolia) and laurel (Laurus nobilis) essential oils were investigated in rainbow trout (Oncorhynchus mykiss). Fish (avarege 10 g) were exposed to different concentrations of essential oils (5, 10, 20, 50, 70, 100, 150, 200, 300, 400, 500 and 600 mg L−1). Anesthesia induction and recovery times were evaluated. In addition, histopathological effects of the essential oils in fish tissues were determined after deep anesthesia. As a result of this study, lavender essantial oil at 200 mg L−1 dose and laurel essential oil at 400 mg L−1 dose showed ideal anesthetic effects on rainbow trout. At these concentrations, deep anesthesia (Stage 4) induction times were 258.0 s for lavender and 189.5 s for laurel. Recovery times at these concentrations were 41 s for lavender and 129.5 s for laurel. No histopathological finding in gill, liver and kidney was observed. Consequently, this study was demostrated that lavender and laurel essential oils can be used as effective anesthetic in rainbow trout.
