Anti-fouling properties of various coating materials for steel wires, i.e. normal zinc-galvanized coating, polyethylene (ionomer resin) coating, and magnesium oxide (HUS)-added (5%) polyethylene coating, were evaluated by suspending coated wires for 17 months under an oyster raft in Hiroshima Bay. The dominant macro-fouling animals were the anascan bryozoan Bugula neritina after four months (February), the bivalve Mytilus galloprovincialis after eight months (June), the solitary ascidian Styela plicata after 12 months (October), and the colonial ascidian Didemnum moseleyi after 17 months (March). Normal zincgalvanized coating was generally superior in its anti-fouling properties to the other two coating materials.
