AB The anaesthetic effects of clove-oil-derived eugenol were studied in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum). Acute lethality and the effects of multiple exposures to eugenol were measured. The estimated 8-96h LC50 for eugenol was found to be approximately 9 ppm. Times to induction and recovery from anaesthesia were measured and compared with MS-222 under similar conditions. Eugenol generally induced anaesthesia faster and at lower concentrations than MS-222. The recovery times for fish exposed to eugenol were six to 10 times longern than in those exposed to similar concentrations of MS-222. Clove oil eugenol was determined to be an accaptable anaesthetic with potential for use in aquaculture and aquatic research. Doses of 40-60 ppm eugenol were found to induce rapid anaesthesia with a relatively short time for recovery in juvenile trout.
