<P>PROBLEM TO BE SOLVED: To solve such a problem that conventional breeding devices for deep-sea organisms have difficulty in controlling the amount of dissolved oxygen in water. <P>SOLUTION: The control device 2 controls the amount of dissolved oxygen in water in a water tank and comprises an air pump that supplies air to the water tank, a circulation path that removes water in the water tank to the outside and returns the water to the water tank, a pressure-feed pump for causing the water to flow through the circulation path and a degasification means arranged in the middle of the circulation path and which causes the water to flow therethrough and removes dissolved oxygen in the water. The control device is capable of appropriately maintaining the concentration of dissolved oxygen in water and is extremely suitable for breeding devices for deep-sea organisms. <P>COPYRIGHT: (C)2013,JPO&INPIT |
