To mark the 17th annual World Oceans Day which fell on June 8, a series of events promoting ocean conservation were jointly held by the Nan’ao Youth League Committee of Dapeng New District, Blue Fin Ecological Marine Conservation Organization, and the Shenzhen Water Search and Rescue Association recently.

The program included marine ecology workshops, a live broadcast of coral spawning, beach cleanups targeting ocean waste, conservation efforts in mangrove wetlands, and interactive ocean-themed games. The organizers aimed to raise public awareness about protecting marine ecosystems and encourage active participation in ocean preservation.

During the live broadcast, Blue Fin Ecological Marine Conservation Organization showcased one of the ocean’s rarest seasonal events: coral spawning. This phenomenon takes place only once a year between spring and summer, emphasizing the urgency of coral conservation.

Viewers witnessed tens of thousands of coral polyps simultaneously releasing pink and orange reproductive cells, creating a stunning underwater spectacle reminiscent of twinkling stars or drifting snowflakes. This vibrant display temporarily colored the seawater in brilliant hues.

Beyond its beauty, coral spawning plays a vital role in marine ecosystems. The released cells provide essential nutrients that sustain marine life, while the fertilized coral larvae settle to form new reefs. These reefs are crucial to maintaining marine biodiversity and ecological balance.

Typically occurring at night, different types of corals release their gametes at various times. The staghorn coral spawning, in particular, is brief, lasting only about 10 minutes, adding to the mystique and wonder of the event.

Last May, volunteers from the Dive for Love organization also observed the spawning of staghorn coral.

Corals are among the oldest marine life forms on Earth, with over 60 species found in Daya Bay and Dapeng Bay.
