Growth of Marine Organisms on Pollution Control Fence

Abstract

The pollution control fences are developed on sites under constructing coastal structures, dredging or reclamation in order to prevent marine pollution. Some of the fences developed for long term are damaged or deteriorated due to the growth of marine organisms on fences. For practical purpose on designing the pollution control fences, the growth of marine organisms have to be quantitatively evaluated. This study investigated their growth on fences at Kan-on marina and Itsukaich sites. The blue mussel is numerically/quantitatively superior. The blue mussel dominates over whole water depth. The average submerged unit weight of each side of fence is 5.0kgf/m2. The growth is affected by environmental condition such as temperature of sea water, current velocity, tide and so on. Accumulating field survey of the growth of dominant organisms at many locations, design method for their growth would be proposed.
