抄録: The effect of substratum slope on fouling invertebrates was examined on suspended man-made structures over a period of one year at the Uranouchi inlet of Tosa Bay, southern Japan. The experimental structures, made of concrete material, have three different slope angles, namely: 0°(horizontal), 45°(incline) and 90°(vertical). A total of 9 independent observations was performed from August 1996 - October 1997. At different periods of submersion, there was an observed succession of fouling invertebrates on the panels showing variations of dominant taxa among the three substratum slope angles. The common barnacles, tubedwelling amphipods and serpulid polychaetes appeared seasonally on the structures. As for the influence of substratum slope, the presence of fouling organisms on sloped substratum (45° and 90°) varied in the dominant taxa as well. Barnacles were markedly abundant on substratum with vertical slope, while the other organisms did not show any preference among the different slopes. A greater number of free-living worms were observed on substratum with small slope gradient.
