The present invention relates to an automatic floating-and-sinking multilayered complex cage-culturing system. The present invention can efficiently and cubically culture abalone or sea cucumbers or both in the open ocean where tidal currents are good and a water quality is good as a case is installed in the water of the sea bottom or a predetermined water layer which is rarely affected by waves in normal days, and the cage is floated on the water surface or sank to an origin place by a simple floating-and-sinking control device in case of necessity such as feeding or maintenance. As several layers of shelters for culturing abalone are stacked on a rectangular frame, and habitat for sea cucumbers is installed under the shelters, the present invention can efficiently and stably culture abalone and sea cucumbers even in the open ocean of which external environmental conditions such as waves and tidal currents are worse than those of the bay. If the structure of the shelters is changed only, the present invention can be utilized as a culturing system for octopuses and hairy crabs. Furthermore, the present invention is composed of abalone shelters, cabinets for stacking the abalone shelters, and a cage frame receiving the cabinets so that the shelters for culturing abalone can be stacked by multiple layers like desk drawers. Therefore, the present invention lifts, manages, and operates only the corresponding cabinet when sorting abalone and replacing the shelters are necessary, thereby reducing manpower and improving the culturing efficiency and productivity. |
