PURPOSE: To produce an ocean current in a culturing sea area and simultaneously improve the purification and dissolved oxygen quantity near the sea bottom by pumping seawater from the side of the sea bottom to the sea surface and diffusing the seawater to the culturing sea area. ;CONSTITUTION: Since the radial diffusion as a pumping device 3 as the center becomes a wave pattern with a pumping cylinder 4 as the center, a current turns round to the rear of an obstacle such as a raft 2 when it collides therewith without discontinuing the wave pattern. Thereby, the wave pattern diffuses avoiding the culture raft 2. When an ocean current is produced by the diffusion, the flow is naturally produced in seawater in a culture cage hung from the raft 2. As a result, the same effects are produced as those in the case of arranging cultured fishes and shellfishes in the ocean current. The diffused water arrives at the bay shore 27 to turn the direction downward as indicated by an arrow 24, further approaches the pumping device 3 along the sea bottom 30 as indicated by arrows 29 and 31 and is sucked into the pumping cylinder 24 as indicated by arrows 21 and 21 to complete the circulating convection.;COPYRIGHT: (C)1994,JPO&Japio
