Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for constructing an artificial fishing ground by which the artificial fishing ground can easily be constructed in a relatively short time without being premised on the presence of a seashore or a lake shore in the bottom face of oceans or lakes and marches where the sediment environment is worsened with bottom mud deposition. SOLUTION: The artificial fishing ground 1 is constructed as follows. Dam members 3 formed of a relatively long nearly rectangular parallelopiped frame-like body 3a formed by combining an H-shaped steel and an L-shaped steel lengthwise and crosswise and a plurality of sandbags 3b hung and held in the frame-like body 3a in a total of 6 are sunk in a sea-bottom face 2. The dam members 3 are mutually connected through supports 4 to thereby form a surrounding dike 5 forming a hexagon which is a figure protruding from the sea-bottom face 2 highly and a closed shape when viewed in a plane. The deposited bottom mud in a region 6 surrounded with the surrounding dike 5 is removed to form a modified bottom face 7. COPYRIGHT: (C)2005,JPO&NCIPI |
