The field survey on the growth of marine organisms on silt curtain was conducted on the site of Tokyo Bay, District K. Blue mussel was superior in numbers among the marine organisms on silt curtain. The average unit weight of the growth or the fouling on each side of curtainis 25 .0kgf/m2. And the average submerged unit weight of that is 3 .0-5 .0kgf/m2. Those weight are almost the same as those of any locations aroud the coast in Japan. The species of marine organisms growing on silt curtain were investigated with reference to sea water pollution. The species were classified into two categories. One is the species which dominated in polluted/eutrophic water. The other is those which dominated in clear/oligotrophic water. Accumulating the field survey on the fouling, indices of marine organisms on sea water pollution would be found.
