Bryozoan assemblages developed on panels submerged at five marinas located along the Turkish Aegean coast were examined between September 1993 and March 1995. The settlement of bryozoan species at the marinas, which had different environmental conditions, showed significant differences. The most stressed marina (Station 1) was represented only by Bugula stolonifera. The colony numbers and the frequency values of some sheet forming species such as Schizoporella errata, Parasmittina sp. and Celleporaria sp. at Stations 3 and 4 increased with increasing the duration time of panels in the sea.
