A movable net-cage structure in underwater is provided to maximize stability in operation by removing danger possibility due to fluctuation of a wire by adjusting a location of the movable net-cage structure. A movable net-cage structure in underwater includes a mesh net(100), a floating part(200), an underwater movement unit(300). The fish is raised in the mesh net. The floating part includes an upper rim(210) and a lower rim(220). The upper rim maintains a shape of the top of the mesh net. The lower rim maintains the shape of the bottom of the mesh net. The movable net-cage structure in underwater maintains a constant shape of the structure while floating the mesh net on the water surface or underwater. The underwater movement unit adjusts a location of the mesh net freely. |
