<P> 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 potentially effective tool for restoring coral reefs, which have been declining around the world . The process bypasses the early growth stages of corals when they are most at risk of dying . Coral fragments known as "seeds" are grown in nurseries then replanted on the reef . Coral is farmed by coral farmers who live locally to the reefs and farm for reef conservation or for income . It is also farmed by scientists for research, by businesses for the supply of the live and ornamental coral trade and by private aquarium hobbyists . </P> <P> Further images: commons: Category: Coral reefs and commons: Category: Corals </P> <Ul> <Li> <P> Fungia sp . skeleton </P> </Li> <Li> <P> Polyps of Eusmilia fastigiata </P> </Li> <Li> <P> Pillar coral, Dendrogyra cylindricus </P> </Li> <Li> <P> Brain coral, Diploria labyrinthiformis </P> </Li> <Li> <P> Brain coral spawning </P> </Li> <Li> <P> Brain coral releasing eggs </P> </Li> <Li> <P> Fringing coral reef off the coast of Eilat, Israel . </P> </Li> </Ul> <Li> <P> Fungia sp . skeleton </P> </Li>
