Abstract

The effects of two new anesthetics (essential oils) extracted from oregano (OO) and eucalyptus (EO) plants were studied in European sea bass (Dicentrarchus labrax) stress response and welfare parameters in comparison to the effects of clove oil (CO) that is one of the most used anesthetics in aquaculture. A time-course study on evolution of plasma cortisol after anesthesia was conducted. Relative expression of stress-related genes, including glucocorticoid receptor (gr), heat shock protein 70 and 90 (hsp70, hsp90) steroidogenic acute regulatory protein (star), cytochrome 11B (cyp11b1) and hypoxia inducible factor (hif) was determined in liver, gills and head kidney after anesthesia.
