The relationship between oceanographic conditions and composition nd density of marine sponge in Spermonde Islands

This article will be presented in national seminar "Bringing the better science for better fisheries and the better future" at Riau UniversityThe research was carried out on several locations in the Spermonde Islands at Makassar area (Laelae, Samalona and Barranglompo Island). The purpose of this study was to determine the relationship between oceanographic conditions and the composition and density of marine sponges. The results of this study showed that there are differences in species composition in different of islands. The Laelae Island that closed to the mainland has low of species composition (5 families) than two other islands (nine families). Similarly, the density of sponge in Laelae Island was 0.8 ind/m2, that was lower than the other islands (Barranglompo was 3.778 ind/m2 and Samalona was 2.95 8 ind/m2). Oceanographic parameters that affected of species composition and density marine sponge were transparence, acidity and turbidity of waters
