This video was filmed in a marine hatchery in Vietnam in which Asian seabass (Lates calcarifer) is being reproduced. In order to achieve a safe handling of large-sized broodstock of Asian seabass, its anesthetizing is necessary. Hypothermia using ice –as shown in the video- was adopted.
Generally, hypothermic anesthesia acts on variety of fishes by drastic lowering temperature through immersing them in crushed ice or ice water.
As shown in the video, it took few minutes to partially anesthetize the Asian seabass broodstock allowing their handling.
