“There were two spawning periods this year on coral colonies across the islands. One was in April and the other occurred on Tuesday, Wednesday, and Thursday. We didn’t see any spawning on Tuesday morning, but they certainly could have spawned earlier in April.”

Spawning was observed in Kīholo Bay, Papa Bay, He‘eia Bay and at Kahalu‘u Bay at various times this week.

Coral reproduction is tied to both the lunar and tidal cycles. “If you track the timing of the moon phase, as well as the outgoing tides, you get a good idea of when coral tend to spawn.”

[Coral reefs](https://coralreef.noaa.gov/gallery/infographic/makes-coral-reef.html) are one of Earth’s most diverse ecosystems. They provide [significant ecological, economic, and societal benefits](https://coast.noaa.gov/states/fast-facts/coral-reefs.html) valued, globally, at about USD$9.8 trillion each year ([de Groot _et al_. 2012](https://coralreefwatch.noaa.gov/external_site_notifications/redirect_de-groot-etal-2012.php), [Costanza _et al_. 2014](https://coralreefwatch.noaa.gov/external_site_notifications/redirect_costanza-etal-2014.php)). Unfortunately, reefs worldwide are threatened by an increasing array of impacts, primarily from [global climate change](https://oceanservice.noaa.gov/facts/coralreef-climate.html), [unsustainable fishing practices](https://oceanservice.noaa.gov/facts/coral-overfishing.html), and [land-based pollution](https://oceanservice.noaa.gov/facts/coral-pollution.html).
