Abstract

In this work the colonization of benthic marine algae on five differents artificial substrates at Guajiru Beach, Ceará State, Brazil was carried out from April through November, 1996. The studied substrates were the following: tyre, iron, granite, ceramics and concrete. A total of 12 species of algae were identified, being seven Rhodophyceae (58,34%), three Chlorophyceae (25%), one Phaeophyceae (8,33%) and one Cyanophyceae (8,33%). The tyre was the most efficient substrate, with the settlement of 10 species and boasting a great algae density, principally Laurencia obtusa (Hudson) Lamouroux and Ulva fasciata Delile. The species Ulva fasciata and Lyngbia confervoides C. Agardh ex Gomont occurred in all substrates.
