Mote Marine Laboratory and Aquarium have announced that several colonies of mountainous star coral that were restored to the wild have been observed releasing eggs and sperm, with a total of seven colonies spawning over a two-day period in August.
The aquarium has worked to restore this key reef-forming species by reintroducing disease-resistant corals that reproduce faster than they normally do in the wild. To induce spawning, which happens when corals reach a certain size rather than age, small fragments of live coral are fused to a larger dead head of coral and create a colony that would otherwise take decades to form.
Already, the restored mountainous star coral colonies have survived 2015 bleaching event, Hurricane Irma in 2017 and a 2019 tissue loss disease outbreak. Other marine biologists in the state of Florida have expressed excitement over the discovery, which shows it may be possible to restore self-sustaining coral colonies into the wild.
