Artificial reefs are deployed in the United States in order to create areas of increased fish presence relative to the surroundings generally to the benefit of recreational fishers and divers. While the success of creating increased fish density has been well documented, the exact effect of these artificial reefs is not well understood. Specifically, the effects of spatial and temporal variation on general fish assemblage in the South Carolina have not been quantified for ARs. This study seeks to determine if there is a consistent fish assemblage across the varying spatial components (reef material, size and maximum height) and to investigate the temporal effects from intra-annual sources (instantaneous, daily, hourly, weekly). The study will characterize the fish distributions observed at Jim Caudle artificial reef using underwater visual census techniques in combination with an exploratory midwater column analysis for multibeam sonar. The study will serve to better understand the ecological significance of artificial reef installations providing necessary information for educated management decisions as well as providing a platform for future studies conducted at the specific site.
