Soon after man first tried to sail the sea or ocean, he discovered marine organisms attached to the underside of his vessel. Biological fouling, or biofouling, the settlement and growth of marine microorganisms, plants and invertebrates onto maritime structures, results in considerable yearly economical loss worldwide. Drag associated with fouled ship bottoms results in reported fuel consumption increases of approximately 30％; microbial activity results in increased rates of corrosion and deterioration; various boring organisms undermine the safety of wooden and concrete structures. It is not surprising, then, that marine biodeterrioration has been the subject of several national and international workshops, symposia and conferences.
