Abstract
    The comparative effectiveness of 2-phenoxyethanol and Propiscin as anesthetics were studied on juvenile sea bass. Both anesthetics showed low toxicity and good hypnotic characteristics, however median survival times at the same concentration of both anesthetics differed. Propiscin showed much lower LT50 than 2-phenoxyethanol, pointing towards its elevated toxicity in juvenile sea bass, even the same concentrations of Propiscin induced slower anesthesia than 2-phenoxyethanol. The most suitable Propiscin concentration for anesthesia was 0.56 ml/l, while the most suitable concentration of 2-phenoxyethanol was 0.32 ml/l for juvenile sea bass. Mortalities after 96 h were induced with Propiscin at lower concentrations then of 2-phenoxyethanol, resulting in the conclusion that the 2-phenoxyethanol is a safer anesthetic for use with juvenile sea bass (Dicentrarchus labrax L.).
