The report concerns the results of a 2-year study of the fouling species occurring in the northeastern Gulf of Mexico offshore from Panama City, Florida. Although the efficacy of one kind of antifoulant organotin was determined, the principal objective of the study was to follow the progressive development and reorganizations of potential fouling assemblages in this region. Differences both in species composition and diversity existing among the stations located 2, 11, and 25 miles offshore and at different depths at the same station 4 to 44 m revealed that the water masses bathing the floats often had very different origins and histories. Moreover, the placement of the 25-mile fouling station in a region thought to be devoid of natural hard surfaces revealed the presence of pelagic larvae of epifaunal species that do not exist along the shore at Panama City. Oceanographic data indicate the possibility that some of these larvae may have been carried by currents from points as distant as Yucatan about 400-500 nautical miles. The exposure-harvest schedule has permitted calculation of valuable data on the secondary productivity of various consumer species in this region. Author
