To our knowledge, no previous anaesthetic experiments are conducted on shabbout
fish. The results from the present study indicated that the induction times decreased
significantly as the doses increased in all the anaesthetics (p<0.05). Induction and
recovery times were significantly affected by the interaction between concentration and
anaesthetic (p<0.05). The effective doses were: 25 and 50 µL L
-1
at 24°C clove oil and
for eugenol, 50 mg L-1
for benzocaine and 500 µL L
-1
for 2-phenoxyethanol. In
conclusion, the four anaesthetic agents could be used as sedatives in culture of shabbout
fish
