Abstract

This research aims to describe the population density of Sea Urchin (Diadema setosum) and it’s distribution pattern in the waters of Abang Island, Galang District, Batam City - Indonesia. Carried out in June 2023. Observations at 3 stations, using survey methods. Sampling was carried out using 3 line transects 20 meters long at each station, placing the transects from the shoreline towards the sea and placing observation plots 1m x 1m on the left and right of the transects. Measurement of water quality parameters; pH, salinity, depth, Dissolved Oxygen (DO), and temperature. The highest density was 2.28 ind/m2 found at station I with a number of 228 individuals and the lowest was 0.81 ind/m2 found at station II with a number of 81 individuals. The distribution pattern of sea urchins (Diadema setosum) was in clustered were found at all stations.
