Depth range, size distribution and density of populations of red gorgonian Paramuricea clavata (Risso 1862) as important factors in maintaining Kornati Archipelago biodiversity, Eastern Adriatic
Red gorgonian, Paramuricea clavata (Risso, 1826) is as sciaphilic gorgonian, which lives on vertical and overhanging surfaces forming large colonies with thick, irregularly ramified branches. Gorgonians play an important ecological role, providing habitats for epifauna and increasing the biomass and diversity of the community. The characteristics of red gorgonian populations were studied using SCUBA diving on four locations in Kornati Archipelago. The locations were selected depending on the strength of human impact. Following parameters were studied: depth range, density and size distribution. Depth range was studied by noting the presence of gorgonians at 5 meter intervals. To estimate the abundance, 60 x 60 cm squares were randomly sampled in each depth range where gorgonians were present. The upper limit of red gorgonian populations in the Adriatic is found at a greater depth than of those in the Mediterranean. Due to that fact this is the first study and first data collected about red gorgonians in the Eastern Adriatic. With this study we expect to determine the status of red gorgonian populations in Kornati Archipelago.
