Several trials of clove, Syzygium aromaticum L. (Merr. & Perry), oil's efficacy as an anaesthetic were-conducted on Mediterranean yellowtail Seriola dumerili Risso, 1810, sea bass Dicentrarchus labrax Linnaeus, 1758, gilthead seabream Sparus aurata Linnaeus, 1758, dentex Dentex dentex Linnaeus, 1758 and sharp-snouted seabream Diplodus puntazzo Cetti, 1777. This product was found to be effective in all species at a dosage of about 40 ppt in seawater, causing total anaesthesia in fish after 3-6 min, with a recovery time of 2-5 min. No undesirable side effects were observed. Clove oil was found to present a number of advantages over other commonly used anaesthetics, including high efficacy at low doses, cost-efficiency, non-toxicity, potential positive side effects, and no need for a withdrawal time for selling the fish after its use.
