Protection against biofouling is essential for efficient operation of boats and ships. Restrictions on the use of traditional, toxic antifouling coatings call for new less toxic methods. Future antifouling strategies will likely be based on more specific action against dominant foulers and will require more detailed information about spatial and temporal differences in fouling communities on artificial substrates. In this study, the recruitment and succession of fouling organisms was examined on artificial (PMMA) panels exposed to natural flow speeds on the Skagerrak coast (Sweden). The recruitment of foulers on static panels was then compared to fouling allowed to develop on boat hulls in surveys of new non-toxic coatings. The temporal and spatial variation in recruitment was examined on a monthly interval within the boating season, from May-September. Furthermore, the succession of the fouling community was examined during the same interval. A total of 12 sessile invertebrate species was recorded on the static panels with dominant foulers being the barnacle Balanus improvisus (July-September) and the mussel Mytilus edulis (June-August). The mean abundance during peak settlement on panels after 1 month's deployment was 370+/-134 individuals dm(-2) for B. improvisus and 340+/-415 individuals dm(-2) for M. edulis . The succession of foulers on the panels led to a dominance of M. edulis (maximum of 7470+/-2830 individuals dm(-2) ) over B. improvisus (maximum of 2295+/-680 individuals dm(-2) ). This was in contrast to the fouling development on boat hulls, examined after 4 months exposure in 3 successive years, where B. improvisus was the dominant species (mean abundance 222+/-104 and maximum 713+/-527 individuals dm(-2) ). Some boats were covered to an extent of almost 100% by B. improvisus with only a few M. edulis (mean abundance 20+/-16). The biomass of fouling on boat hulls varied from average dry weights of 1.3+/-1 to 13+/-5 g dm(-2) . These results show that extrapolation from static panels (common in evaluation of antifouling performance) to fouling on boat hulls may be problematic.
