Seasonal settling patterns and community development of the
fouling complex on gelcoat-covered fiber glass plates
(103.22 cm2 ) were observed from September 1976 to September
1977 at three stations in northern Lake Worth, Florida. Percent
coverage for each species was estimated using 60 points
randomly positioned over the plate area. Physico-chemical
conditions at stations 1 and 2 were relatively stable, whereas
station 3 was subjected to wide variations in salinity and,
to a lesser extent, dissolved oxygen. Plates at stations 1
and 2 consistently collected more species than those at
station 3. Peak settling and growth at all stations occurred
in the spring and early summer. Three species settled only
on plates that had been previously colonized. Even though
gelcoat-covered fiber glass was designed to discourage fouling,
it proved to be a satisfactory substrate for a thriving community.
