dc.description.abstract The present work was conducted to determine the effects of clove oil as an anesthetic on post- larvae (mean length 13.42±0.84 mm) and juveniles (43.57±0.94 mm) of the giant freshwater prawn, Macrobrachium rosenbergii. In the first of three experiments, exposure to ethanol for 15 min was ineffective in tranquilizing the freshwater prawns at concentrations of 75-625 mg/l for postlarvae and 375-5,000 mg/l for juveniles, indicating that ethanol could be used as a solvent for clove oil without contributing to any anesthetic reaction. In the second experiment, prawns were exposed to one of six clove oil concentrations for 15 min (15-125 mg/l for postlarvae; 75- 1,000 mg/l for juveniles). For postlarvae, the fastest induction (0.90±0.05 min) was achieved at the highest concentration (125 mg/l) but all prawns in this treatment died. Induction and recov- ery times in concentrations of 30, 45, and 60 mg/l were all under 15 min. At 75 mg/l, postlarvae were tranquilized in a relatively short period (3.30±0.10 min) and recovery time was maximum (45.17±0.20 min). For juvenile prawns, concentrations of 750 mg/l and up were fatal while 125 and 250 mg/l induced anesthesia in 78.30±0.20 and 66.83±0.18 min, respectively, with recovery in 4.21±0.12 and 16.91±0.16 min. As far as induction and recovery times are concerned, clove oil was a suitable anesthetic only for postlarvae. The third experiment revealed that a concen- tration of 15 mg/l could safely be used to transport postlarvae up to three hours. en_US
