PROBLEM TO BE SOLVED: To provide a culture method of live sea urchin not slimming as long as about 2 weeks, even if low-temperature ocean deep water is not used.SOLUTION: Live sea urchin is cultured and prevented from slimming in a low-temperature sea water tank 3 by a process in which, in a heatproof facility 1 having little heat entry, a lower-temperature culture environment than ocean deep water is created, by installing a container 1a packed with ice 2a and a fresh water tank 2 contaminated with ice 2a, and by immersing a sea water tank 3 filled with sea water into the fresh water tank 2, to thereby lower the temperature of sea water in the sea water tank 3.COPYRIGHT: (C)2015,JPO&INPIT【課題】低温の海洋深層水を利用しなくとも2週間程度は身痩しない活ウニの畜養方法の提供。【解決手段】熱侵入の少ない防熱した施設内1に、氷2aを詰めたコンテナ1aと氷2aを混入した真水槽2に海水を満たした海水層3を浸すことで海洋深層水よりも低温の蓄養環境を作り、海水槽内3の海水を低温にする工程により、この低温の海水槽3で活ウニを畜養し、身痩せの防止を実現する。【選択図】図1
