‘Test-tube coral babies’ may mend reefs

‘Test-tube coral babies’ may mend reefs – Yahoo! News
Looking like an upside-down, underwater snowstorm, most corals in the Keys, Gulf of Mexico and the Caribbean release eggs and sperm into the water a few days after the full moon in August. In the wild, eggs and sperm randomly mix and fertilize to become larvae. Some take root to become foundation blocks for new coral.

Researchers led by Margaret Miller, an ecologist with the National Marine Fisheries Service, gather spawn in cone-shaped, tent collectors anchored over portions of the coral reef off Key Largo. The spawn is blended in jars and the portion that fertilizes is transported to a field laboratory.
