Summary:PURPOSE:To keep the environment in a breeding tank to good state by placing a water-wheel for supplying oxygen to water and removing air from water and an adsorbent for carbon dioxide gas in a closed space above a water tank. CONSTITUTION:A space closed with a shielding member 20 is formed above the water surface in a breeding tank 10 for the cultivation and breeding of various kinds of fish and shellfish. Oxygen is supplied to the space at a prescribed pressure with a gas-supplying part. Water in the tank is bubbled with a water-wheel 28 to remove gas from water. An adsorption part 22 containing an adsorbent is provided to remove carbon dioxide gas in the gas phase of the closed space.
