چکیده [English]

Anesthetic effects of valerian (Valeriana officinalis) and Clove oil were examined on rainbow trout (Oncorhynchus mykiss) in two weight groups (mean weight 26.02± 6.3gr and 350.5± 5.09 gr) at 18oC and pH of 7.6. For this purpose concentrations of 5, 10, 15, 20, 25 and 30ml of valerian extract in 1 lit of pond water and 500 and 1000ppm of clove oil were prepared. In these experiments, immersion method was used for fish anesthesia. Four fish in each treatment with similar mean weight were exposed to aforementioned concentrations of anesthetic agents. The obtained results confirmed sedative and anesthetic effects of valerian extract on rainbow trout. Sedation and anesthesia were not observed in those fish exposed to clove oil within suitable time span (below 3 minutes) therefore clove oil treatment was discarded from the experiments. The most suitable concentration of valerian extract to induce sedation and anesthesia in smaller and larger weight groups were 15ml and 25 ml respectively and sedation, anesthesia and recovery were achieved in less than 3 minutes.
