초록

The objective of this study is to determine the optimal dose of lidocaine-HCl for anesthetizing Siberian sturgeon, Acipenser baerii, to investigate the relationship between anesthetic effectiveness and fish size, and to analyze re-anesthetic effects and stress responses to lidocaine-HCl use. The anesthesia and recovery times were affected significantly by the concentration of the anesthetic and fish body size. Anesthesia time decreased significantly as both the lidocaine-HCl concentration and body size increased (P < 0.05), while recovery time decreased as the lidocaine-HCl concentration increased (P < 0.05). Anesthesia time and recovery time decreased significantly as the lidocaine-HCl concentration and water temperature increased (P < 0.05). Plasma cortisol, plasma glucose, and lactic acid concentrations were indicative of stress reactions in this experiment. At 1-, 2-, and 3-day intervals, the anesthesia and recovery times increased significantly as the number of anesthesia treatments increased (P < 0.05) but were not significantly different between duplicate and triplicate treatments (P > 0.05). In 4-day interval groups, anesthesia and recovery times were not significantly different (P > 0.05) among the initial, duplicate, and triplicate treatments. Anesthesia and recovery times increased significantly with the second anesthesia treatment (P < 0.05). Anesthesia time decreased significantly as the number of anesthesia treatments increased (P < 0.05), but recovery times did not differ significantly with the increase in number of anesthesia treatments (P > 0.05). Lidocaine-HCl concentrations of 50 and 250 ppm in the larval and juvenile groups, respectively, showed an optimal anesthesia time of approximately 1 min. The optimal anesthesia interval of lidocaine-HCl was 4 days, and frequent anesthesia resulted in negative effects by inhibiting sensitivity.
