SOLUTION: The marine structure is obtained by spreading a net 1 under a cover 3 for blocking light and arranging a strut 2 so as to pass through the net. The marine structure stands in the sea and when the sea bottom is a sandy area, the strut 2 is solidified with a pedestal concrete on land and sandy area of the sea bottom is dug and the pedestal concrete is embedded therein to install the pedestal concrete on the sea bottom. After the pedestal concrete is installed on the sea bottom, the coral is transplanted in the part of the cover 3. Since the structure prevents the transplanted coral from damage due to Acanthaster, coral grows after several months and creates beautiful scene.
