Three different methods to induce either anesthesia or sedation were examined for the purpose of applying to transport of live fish. Two of them, production of carbon dioxide by adding sodium bicarbonate and sulphuric acid to water, and bubbling carbon dioxide and oxygen into water for a short duration until the fish were anesthetized, were simple and cheap ways but were found to be unsuitable in the case live transport, because these methods were applicable only in cases of very low density of fish. The third method, bubbing carbon dioxide and oxygen into water throughout the course of transport was safe for carp when Pco2 and Po2 in water were kept at 95-115 mmHg and 400-480 mmHg, respectively, but is considered to be impractical because of the laboriousness and high cost in maintaining Pco2 and Po2 at their optimum levels. And this method was found to be inapplicable for porgies, because safe Pco2 was not effective and effective Pco2 was not safe.
