Artificial reef (Hexadomes) off the northern coast of Bali. These hexadome artifical reef structures are part of a reef rehabiliation project off the north Bali coast. Built by local fisherman in Les Village, the structures provide a large surface area on which corals and other organisms can settle and grow. They form a three-dimensional landscape on the previously bare reef flat, and rapidly become refuges for large numbers of fish and other sea creatures. The domes will last for many years- long enough for the natural reef to become well established once more. The fishing groups in Penuktukan, Taman Sari and Yeh Biu have installed 22 hexadomes so far. These structures already give visitors the opportunity to observe more than 20 species of reef fishes. The hexadomes in these photos are about 2 years old. This is one of many rehabiliation projects organized by LINI (The Indonesian Nature Foundation). LINI (aka Yayasan Alam Indonesia Lestari) is an Indonesian based non-profit organization dedicated to conserving Indonesia’s coastal resources with primary emphasis on ornamental fisheries.
