PURPOSE: A device for culturing seafood is provided to prevent from a supporting unit being buried in a targeted area deeper than a certain depth by pressure of ocean current and minimizing damages of the supporting unit by alleviating impact in case external force is added to the supporting unit. CONSTITUTION: A device for raising seafood(1) comprises supporting units(10) which are composed of synthetic resin materials, supporting wires, and raising ropes. The supporting unit comprises a supporting pipe(11), a cover unit(12), a connection pipe(13), support stands(14), and side direction supports(15). The supporting pipe comprises an outer tube, an inner tube, and supporting pieces. In the outer tube, one or more penetration hole is formed in the center of one side of lateral face along the longitudinal direction. In the inner tube, a pass hole is formed from one end along the longitudinal direction in order to inflow water which flowed in through an inlet hole of a cover unit. A plurality of supporting pieces is extended from one side of an outer surface of the inner tube in all direction. The support piece is connected to the inner surface of the outer tube so that the air layer(11ca) is formed between the inner tube and the outer tube. |
