PROBLEM TO BE SOLVED: To easily remove a marine organism within a flow passage pipe, to prolong the lifetime of the flow passage pipe and to make the price low in a marine organism removal structure in which the flow passage pipe for circulating seawater is provided and the marine organism in the flow passage pipe is removed.SOLUTION: Inside of a flow passage pipe (6), a pipe member (7) for deposition is disposed in a removable manner for allowing the deposition of a marine organism so as to prevent the marine organism from being directly deposited to an inner circumferential surface (6A) of the flow passage pipe (6). Specifically, the flow passage pipe (6) is disposed in an overflow bank (2) so as to circulate seawater between the open sea (S) and a bay (R) resulting from partitioning the seacoast (1) by the overflow bank (2), and the pipe member (7) for deposition is provided inside in a removable manner. |
