Biorock® technology was brought to Gili Trawangan in 2004 and is now home to 37 Biorock® structures and is the second largest Biorock® site in the world. The Biorock® Process involves a submerged steel structure that applies a safe low-voltage electrical current. Small pieces of live broken coral are then strapped to the structure and have been shown to grow at 3-5 times the normal rate while coral survival under higher water temperatures and pollution increased by 16 to 50 times. Juvenile coral is thriving in these artificial environments and smaller reef fish take refuge in the shelter of the structures. Filefish, Bannerfish, Moorish Idols, Boxfish, Cowfish, Pipefish and Frogfish are common and the occasional Crocodile fish. Much research is undertaken along these reefs. These dive sites are accessible to all diver levels.
