Kerapatan Clathria reinwardti dan Spheciospongia inconstans di Reef Flat Pulau Barranglompo, Kepulauan Spermonde, Makassar Article in Jurnal Kela

This study aims to determine the density of the sponges Clathria reinwardti and Spheciospongia inconstans in the reef flat of Barranglompo Island, Spermonde Archipelago, Makassar. The method used is belt transect using a roll meter as a reference for distance. The starting point of the roll meter ± 50 m from the shoreline is drawn perpendicularly to the end of the reef reef by 3 transects with a distance of ± 50m between the roll meters. At each 25m interval the observations were made using a belt transect size of 15m × 5m as the limit of the observation. In each quadrant transect, were done first is documenting of each sponge then count the number of species present in each quadrant. The results showed that the density of Clathria reinwardti at stations I and II were 0.13 and0.14/m2 respectively and were not significantly different, while those at stations III and IV were 0.25 and 0.31 /m2 respectively and not significantly different. Station I and II are significantly different from stations III and IV. The density of Spheciospongia inconstans at station I 0.02 /m2, station II 0.14 /m2, station III 0.67 /m2, and station IV 0.44 /m2. The sponge density of S. inconstans between stations was significantly different. The density of C. reinwardti at stations III and IV was higher andsignificantly different than stations I and II, while the highest density of S. inconstans was found at station III followed by station IV, station II, and station 1, and was significantly different among the four stations.
