Sažetak
In this study we characterized coral assemblages of an off‐shore coralligene banks dwelling at 50‐ 100 m depth on a four locations near Islands of Dugi otok and Kornati (eastern Adriatic Sea). Surveys were made by scuba diving and ROV‐ imaging. Assemblages of suspension feeders, dominated by the gorgonians Paramuricea clavata and Eunicella cavolini together with Savalia savaglia, were examined. This three surveyed species were distributed into two areas corresponding to different habitat preferences: a more elevated hard ground ("steeple") hosting yellow gorgonian and a gently sloping, silted rocky bottom ("pyramid") hosting the other two coral species. The study area is subjected to a heavy pressure from the professional fishery, resulting in the mechanical damage of numerous colonies, some of which are then overgrown by various epibionts (mostly red algae and hydrozoans). These off‐shore rocky banks are widely known among recreational and professional fishermen due to their rich fish fauna. The main problem about off‐shore coralligene bank is the lack of knowledge and also effort to characterizing the extent of the impact and consequences on these benthic communities. The management of these areas is big issue, still lacking of an effective solution in the Adriatic Sea. This report represents a preliminary data of the whole study and contributes to the knowledge of deep coralligene banks in the eastern Adriatic Sea.
