The objective of this study was to investigate the effects of lemon peel oil as an anesthetic agent on
rainbow trout (Oncorhynchus mykiss), which is intensively produced in Türkiye. For anesthesia efficacy
evaluation, rainbow trout with an average weight of 51 g were exposed to different concentrations of
lemon peel oil (500, 1000, 2000, 3000, 4000, and 5000 μL/L). Induction and recovery times were
recorded by using a digital stopwatch for each fish. According to the results, it was observed that there
were significant differences between the anesthetic substance concentration values, and as the
concentration of lemon peel oil increased, the induction time decreased (P˂0.05). However, it was
determined that, as the concentration of the anesthetic agent increased, the time it took for the fish to
recover from anesthesia shortened (P˂0.05). As a result of the experiment, it was observed that the fish
entered anesthesia in less than 3 minutes at a dose of 5000 μL/L lemon peel oil and recovery time from
anesthesia in less than 5 minutes. Our findings indicate that 5000 μL/L is the best concentration of lemon
peel oil for rainbow trout in our research.
