The variations of colonization, growth pattern and succession of benthic marine algae on various artificial substrata have been examined. Seven kinds of artificial substrata, i. e., concrete, slate, glass, wood, rubber, aluminium and PVC plates, were placed at upper, middle and lower intertidal zones of Poryong and Sochon, East Coast of Korea, during the period of January - November 1985. As a whole, coccoid blue-green algae and diatoms were observed as pioneer algae settled over newly placed substrata, and then filamentous green and crustose coralline algae were gradually luxuriant, whereas diatoms decreased in abundance. Colonization and growth of marine algae were significantly influenced by differences between tidal levels or the kind of artificial substrata.
