Aquaculture of coral
Coral aquaculture, also known as coral farming or coral gardening, is the cultivation of corals for commercial purposes or coral reef restoration. Aquaculture is showing promise as a tool for restoring coral reefs, which are dying off around the world. The process protects young corals while they are most at risk of dying. Small corals are propagated in nurseries and then replanted on the reef.
Coral is also farmed by scientists for research, by businesses for the live and ornamental coral trade, and by private reef aquarium hobbyists.
Coral reef farming involves extracting a part of a coral colony or free-floating larvae from a reef, and growing them in a nursery until outplanting would be successful. It is commonly referred to as the "gardening method" and has been compared to silviculture as a management practice that mimics natural ecosystems.
Adult corals can be transplanted onto a reef, usually in a damaged area. Coral is farmed for conservation reasons in the Philippines, Israel, Solomon Islands, Palau, Fiji, Marshall Islands, and Japan. Land-based coral farming occurs in public aquariums in North America and Europe.
