Abstract


Abstract: There are only few studies of "fouling" on the southern coast of São Paulo. The evaluation of sessile animals recruitment throughout the year, using artificial substrate plates (ceramic tiles) is the main goal of this work. Research and collections occur in the estuary beach Guaraú, Peruibe-SP municipality in the outer buffer zone of the current Sustainable Development Wildlife Reserve of Juréia-Itatins. As a specific goal, this study intends to evaluate the coverage percentage, evaluation of biomass (AFDW - ash free dry weight); the biovolume of the material collected and the calculation of the indices of diversity and dominance. The monitoring of this is done with fouling fauna collections and scraping the ceramic substrate every three months at four locations along the estuary in order to obtain an assessment of the stages of ecological succession and recruitment strategies and competition between species. Recruitment began on June 2014 and ending in June 2015. The site 4 showed greater accumulation of biomass over a year and the species that got strong dominance over the 12 months was the barnacle Balanus trigonus.
