Kelimpahan Dan Keanekaragaman Spons Di Pulau Pasumpahan Sumatera Barat

---

Sponges are the most primitive multicellular animals that live in various types of waters ranging from fresh, brackish and marine. Sponges live at the bottom of the water, usually embedding themselves in hard substrates such as rocks or corals and competing with other attached organisms for food space. The purpose of this study was to analyse the abundance and diversity and to determine the differences in sponge abundance at different depths. This research was conducted in March 2024 in the waters of Pasumpahan Island, West Sumatra. This research used survey method and belt transect method. The sampling location was divided into 3 stations consisting of 3 sampling points. Station I is located in the tourist area, Station II in the dock area and Station III is in the area facing the open sea. The results showed that the highest abundance based on depth was found at station I with a depth of 5 m, namely 1071.4 ind / ha and the lowest abundance was found at station II with a depth of 7 m, namely 714.286 ind / ha. The t-test results obtained a significant value of less than 0.05, namely 0.048, which means that the abundance of sponges at different depths is significantly different. The diversity index ranges from 1.930-2.013 which indicates the level of sponge diversity in the waters of Pasumpahan Island is classified as moderate. Based on the results of the T test shows a significant value of more than 0.05, namely 0.795, which means the abundance of sponges at two depths is significantly different. Thus, hypothesis H0 is accepted and hypothesis H1 is rejected, where there is no difference in sponge abundance between depths.
