Tilapia displayed about 1 min of hyperactivity, and the induction time of anesthetized was about 3 min during CO₂ anesthesia, both the behavioral analysis and plasma cortisol levels showed that tilapia were more sensitive and stressed to the CO₂ anesthesia than MS-222 anesthesia. During air exposure, both anesthesia groups had good sedative effects, and the survival time of un<a name="OLE_LINK19">anesthetized</a> group, CO₂ anesthesia group and MS-222 anesthesia group were 331, 489 and 528 min respectively, and the <a name="OLE_LINK176">survival time and survival rates of the anesthetized tilapia were significantly increased.</a> Considering the efficacy, ease of use, as well as safety, <a name="OLE_LINK21"></a><a name="OLE_LINK20"></a><a name="OLE_LINK84"></a><a name="OLE_LINK82">the results of this study showed that CO₂ was </a><a name="OLE_LINK13"></a><a name="OLE_LINK175">an ideal</a> anesthetic to improve air exposure duration of tilapia, and carbon dioxide anesthesia of tilapia potentially can be translated into an industrial <a name="OLE_LINK14"></a><a name="OLE_LINK65">short-time air exposure </a>procedure.</p> Carbon dioxide, Anesthesia, Tricaine Methanesulfonate, Tilapia, Behavioral and physiological response, Air exposure duration 82 92 http://jifro.ir/browse.php?a_code=A-10-2471-1&slc_lang=en&sid=1 X.
