Abstract
The present invention provides a method of preventing adhesion of aquatic organisms on structures in the water such as ships. In the method, the underwater part of a structure in the water is covered up with the sheet. The sheet is made of a polyolefin and less than 1 mm thick, and has apertures each of which has a surface area of 1 to 60 mm.sup.2, the surface area in total of the apertures occupying 20 to 80% of the entire surface area of the sheet. The sheet has a tensile strength of 15 to 37% as measured under JIS L1096A and a tear strength of 3 to 9 kg as measured under JIS L1096A-1.
