Description:
Anaesthetic effects of essence, water and water-alcohol extractions of clove oil were studied in rainbow trout
(Oncorhynchus mykiss), common carp (Cyprinus carpio), Persian sturgeon (Acipenser persicus) and Penaeus
semisulcatus under various water quality conditions consisting of water temperature, pH and salinity. The
obtained results showed that both water and water alcohol extractions had no anaesthetic effect at concentration
upto 2000 mg/L whilst, essence could aet as a suitable anaesthesia at 〉50 mg/L. The most suitable anaesthic
effect by essence in rainbow trout was 250 mg/L provided at 5 C
and pH 7. Also, clove oil essence showed the
best anaesthetic effect in carp under water quality conditions consiting of water temperature at 25 C
and pH 7-8
or water temperature at 30 C
and pH 9. In addition, clove oil essence at 75 mg/l and 12 mg/L gave the best
anaesthetic and sedation effects in Persian sturgeon provided at 21-23 C
and pH 8.3, respectively. Furthermore, clove oil essence at concentrations above 50 mg/L was able to act as an anaesthesia in P. semisulcatus. However,
the best anaesthetic concentration was depended on water quality conditions consiting of water temperature, pH
and salinity.
