More Information about Coral Spawning

The researchers had witnessed coral spawning, an annual event, which occurs in all coral reefs around the world. Today we know that many corals living on the Great Barrier Reef spawn about four to five days after the full moon in October or November and sometimes in December. 
Why do corals spawn after a full moon, and why do the east and west coast corals spawn at such different times of the year, despite the fact that these reefs have many species in common? 
There are three triggers that set off spawning in corals, according to coral reef expert Associate Professor Peter Harrison from Southern Cross University.

  • Firstly there must be a gradual rise in sea temperature, triggering the eggs and sperm to mature inside the adult coral.
  • Second, the lunar cycle coordinates the exact moment at which the corals release their precious cargo into the water.
  • The third stimulus is related to the diurnal cycle - coral need the darkness of night to do the wild thing!
