Coral Spawning Time at Anse Chastanet Resort, Saint Lucia

Soufriere, Saint Lucia, August, 2015…It happens once a year… one of nature’s most spectacular and rare performances – Coral Spawning.  And it occurs right off the beaches of Anse Chastanet, Saint Lucia.  Each August, the resort’s scuba diving team incredibly and accurately predicts the night spawning and prepares to take novice and experienced divers and snorkelers to observe the remarkable phenomenon.  This year the event is September 5 & 6.

What is coral spawning and why is this so rare?

First discovered in the 1980s at Australia’s Great Barrier Reef, this annual mass reproduction phenomena overturned a long-held belief that most coral species reproduced by fertilizing their eggs internally. This “new” external phase of reproduction is now known to be critical to coral reef – and our own ecosystem – survival. Tropical coral reefs, although out of sight, are essential to our world-wide food chains.

Each year, coral release millions of packets of egg and sperm cells that appear as a white and pink upward underwater “snowfall” of  massive clouds. After they drift to the surface for fertilization, the sea will be partially covered by the slicks of coral larvae before they settle to the bottom destined to build the next generation of one of the ocean’s most vital organisms.

Tropical reef-building corals have tiny algae living symbiotically inside individual polyp tissue and neither could survive without the other. The coral gives the algae a substrate and home, and in return, the algae provide the coral with food. While much of the coral spawning process remains a mystery, scientists from all over the world study these miraculous events, and now know that triggers of this annual wonder are the right combination of temperature, day length, rate of temperature change, lunar cycles, time of sunset, and chemical synchrony. The ideal time for the release of the reproductive cells is a week or so after a full August moon an hour or two after sunset providing the cover of darkness. This method of mass spawning increases the chances of larvae survival by overwhelming fish predators.

How is Anse Chastanet conserving and preserving this rare phenomenon?

This spawning phase of reproduction is now known to be a weak link to world-wide coral reef survival as it can only happen when conditions are just right – and is the phase most sensitive to human activity, non-point source pollution, and climate change. Anse Chastanet is able to provide access to this event and resource despite its close proximity due to it exemplary and progressive sustainable designs and architecture by minimizing impervious surfaces, keeping shorelines green and stable, and completely preventing runoff from entering the water – preserving this wonder for future generations.
