Abstract
Anesthesia may depress the immune system in mammals and fish. In the present work, two anesthetics used in aquaculture, clove oil (0.445 mM) and benzocaine (0.225 mM), were tested to observe their effects on the stress response and innate immune system activity of gilthead seabream (Sparus aurata L.). Results showed that both anesthetics induced increased blood glucose and serum cortisol levels. In addition, benzocaine depressed lysozyme activity, produc- tion of reactive oxygen species and pinocytosis activity. These were not depressed by clove oil, suggesting that clove oil is a safer anesthetic for seabream as it does not cause immunode- pression in anesthetized fish.
