Abstract

Batee Island is one of the small islands in the Aceh Besar region and is uninhabited and directly faces the Indian Ocean. Batee Island's waters have the potential for marine biota, especially coral reef ecosystems, and other associated biotas. This study aims to determine the percentage and comparison of live coral cover in Batee Island waters and determine the genus' composition in Batee Island waters. This research was conducted in October-November 2016. Collecting coral reef data using the LIT (Line Intercept Transect) method. The results showed that the live coral cover in Batee Island's waters differed between the East and West Batee Islands. The coral reefs' average condition in Batee Island waters at shallow depths (0-5m) is 41.41%, and deep (6-10m) is 36.52%. Overall, the conditions and live coral cover in the waters of Batee Island are classified as moderate. In the waters of Batee Island, there are 31 coral genera. The highest percentage of corals was the genus Acropora (50.02%).Keywords:Batee IslandConditionCoral reefCoral cover

Highlights

  • Coral reef ecosystems are the most biologically productive ecosystems and very sensitive to pressure (Bengen, 2004; Ulfah, 2011)

  • Based on Government Regulation No.37 of 2008, the Aceh waters area is around 74,798.02 km2 or 7,478,801.59 ha and a long coastline of 2,666.27 km with clusters of large and small islands

Summary

Introduction

Coral reef ecosystems are the most biologically productive ecosystems and very sensitive to pressure (Bengen, 2004; Ulfah, 2011). The coral reef ecosystem is in shallow water. According to Muttaqin et al (2014), coral reefs have a significant role as habitat, feeding ground, nursery ground, and spawning ground for various biota that lives in association with coral reefs and a source of income for humans. Based on Government Regulation No. of 2008, the Aceh waters area is around 74,798.02 km or 7,478,801.59 ha and a long coastline of 2,666.27 km with clusters of large and small islands. Aceh Besar was awarded a coastal area with a 295 km coastline, an area of sea waters reaching 1,355.90 km, and many small islands of 21 and had two large islands. Most of the area is on land, and a small part is in the islands. In the West, Aceh Besar District is directly adjacent to the Indian Ocean (BPS Aceh Besar, 2014)
