Problem to develop the effect of anesthesia on fish and shellfish.Solution: the concentration of the salinity according to the anesthetic object is adjusted to the water, and the anesthetic water is produced by the process of adjusting the concentration of carbon dioxide to the concentration of carbon dioxide. As an example of the adjustment method of the salinity, there is a method of adjusting so as to approach the osmotic pressure of the body fluid of the anesthetic object.No selection【課題】魚介類に対し、麻酔効果をより早期に発現させること。【解決手段】水に対し、麻酔対象に応じた塩分の濃度調整を行うとともに、さらに麻酔効果を奏する二酸化炭素濃度へ調整する工程によって麻酔水を製造する。塩分濃度の調整方法の一例としては、麻酔対象の体液の浸透圧に近づけるように調整する方法がある。【選択図】なし
