broadcast spawning

Novel technologies establish a new paradigm for global coral reef restoration, with in situ spawning of mature, environmentally resilient corals in five years instead of decades.

Our novel technique involves planting several small fragments of slow-growing corals onto dead coral heads. The fragments eventually fuse, forming a large colony in a fraction of the time that it takes wild corals to build reefs.

Groups of corals release all of their eggs and sperm once a year, but the timing of their spawning is under threat from climate change.

Researchers recovered audio recordings of the fish’s mating calls in the eye of the storm.

Chemical cues dispersed by mussel eggs may attract sperm that are their perfect match.
