Few months ago, I was invited to come up to Apollo beach, Florida to partake in the year's last spawning event in Florida Aquarium's center for conservation facility.
This took months of planning, and Keri O’Neil’s team being so good at what they do, we were able to predict a day for me. Which isn’t really easy due to having to drive 4 hours each way but I was excited to participate and to document the work of this amazing team that ensures the long term survival of the multiple species of corals that are functionally extinct in the wild. I was also very nervous at the thought that it would not go our way and that we had missed the narrow window of the spawning season. With nature, nothing is 100% and you have to expect the unexpected at times.
Me and my Shane Lafreniere of 247 Aquarium drove up to meet up with Keri and her team and we got to work and work we did. Both Shane and I, later joined by Chris Meckley of ACI Aquaculture, we worked until wee hours of the night and at the end, we had a moment to reflect what had happened and thought came to us as an realization that this may be where our industry’s future lies with all the bans and red tapes happening. Not now, maybe not for a while but something that’s definitely possible.
After sitting down to edit the hours of footages that I have made, I made the decision to split the trip into 2 videos. Part 1 being narrated by Keri, she will tell us everything that has happened in this trip. As an scientist, she will detail every detail and step such as identification of the corals, process of fertilizations, process of cell divisions that ultimately ends up as baby corals. With upward of 90 plus percentage of having these baby corals settle properly now, they estimated having close to 150,000 baby corals from this single event.
With this video, I was able to achieve something that was on my bucket list for many years ever since Jamie Craggs first introduced this method and showed the glimpse of the future for conservation and preservation efforts and if I were to boldly predict, our industry’s future. By coming here not only I was to participate but ultimately document and produce what I consider the most important video of my career at reefs.com.
I sincerely want to thank Keri O’Neil and Florida Aquarium for allowing my team to come up and participate/ document and release these footages and to my friend, Shane Lafrenier for always coming to help with all these work. I can’t wait to release part 2 where it will be more of a vlog style that you will see what happened through my eyes and perspective.
Thank you for watching this video. I hope you guys enjoy it and hopefully learned something from it. Please comment down below your thoughts and share this video to raise awareness of Florida Aquarium’s amazing work!
Happy reefing.

@@Reefscom I really don't understand those who care about the time limitations of any video. Specially with real substantial content. People can pause and get back to that video if they don't have enough time to watch. Anyways, it is what it is. I'll wait for the part 2 then. 😁

Excelente material, esperamos la segunda parte, solo una pregunta, ¿Este tipo de desove solo se da en coral sps o algo similar también en lps?

My spanish is not good enough to answer in spanish, but I can in english! Similar spawning does happen in LPS corals! But some corals are brooders (some SPS and some LPS), and they release fully developed larvae rather than eggs and sperm.

A question for Keri and her team - has there been any discussion of aquarist-assisted migration of these endangered corals, taking some of the progeny you produce and planting them out in more northern locations where shifting conditions might be more favorable?

Hey Matt, I'm not Keri, but perhaps maybe I can answer this for you. They can't outplant outside of short distance from their collection site. In order to replant, you need to cross many red tapes which includes showing paperwork and trails of where these were collected, mixed with what corals for fertilization, and that they weren't contaminated by ANY amimals amd pathogens found in different parts of the world. I think we had brief conversation on this before. If you have a moment later, I can call you to explain bit more in detail.

Yes! This is something that is discussed in the coral restoration community as a whole. However, in Florida there is a limit to how far northward corals will survive (as of right now) due to the Bahamas Fracture Zone on the eastern shelf, which causes the water to get significantly colder in the winter northward of this point. However, we have been working with the Reef Institute in West Palm to provide more corals for planting in that area. Corals in Palm Beach, Broward, and parts of Miami-Dade did not bleach as severely this past winter as the Keys.

I was talking about predicting these events and was wondering if gravity is known to have any effect on spawning events and/or how corals detect the moon? It seems like the spawning events usually happen when the time of light from Earth to the moon is at a low, meaning the moon is at its closest point of orbit. Is there any logic to this measurement as a form of indicator? Curious to see what other people think. Obviously light seems to be involved, but not all corals get full moons if it's cloudy or stormy. Can the lunar cues that initiate spawning be independent of actual full moons? I guess I'm just curious as to what wavelength is being emitted from the Moon, given the moon really doesn't reflect a lot of light to begin with and the onset of ALAN shown by Smyth et al 2021 regarding the global atlas of light at night under the sea paper and how they were recording light impact as deep as 50m in some areas, in the blue spectrum of visible light.

Gravity(tides) absolutely play a role in wild coral spawning.

Good question! Most coral spawning events occur within a week or so after a full moon during warmer months. It is believed (from a rather small amount of research) that corals can sense whether the moon is "up" using light-receptive proteins called opsins and cryptochromes. These respond to wavelengths of light that can penetrate very deeply in the ocean and can even penetrate clouds quite well. Corals in a lab setting can be switched to spawn at different times even when the gravitational pull would be different, so it is believed it is the presence/absence of moonlight itself (in relation to when the sun sets), rather than gravity, that is inducing the release of the eggs and sperm. But there is a lot more to learn on this!!

@@KeriONeil That makes a lot more sense than the model I had of gravity potentially having an effect on coral specifically, rather than as a tide and the cofactors of that. Based on your observations, do you think it's a bistable opsin along the lines of the MosOpn3 and LamPP in a molecular property-dependent manner, similar to the Mistumasa et al 2022 study for color dependant control of GPCR signalling? But... in corals ? That would make a lot of sense, given opsins have a history of changing or being lost with time and natural evolution. They would provide a benefit to the corals with the right opsins to cater to night time release of eggs when it's potentially possible those eggs and sperm also have opsins to find eachother under the moon. Okay, maybe that last part is a bit of a stretch, but it could probably be tested for or maybe it's already been tested for and I don't know. Either way I appreciate your reply, the separation of spawning from gravitational impact is exciting.

Love this!!! How do you sex corals? Assuming that many are not hermaphroditic, and that having a reasonable mix of male/female matters.

Hello @telegraham. Actually, the majority of coral species are hermaphroditic, but some are gonochoric. You cannot tell the sex visually, you have to preserve samples and either dissect them or use histology, or wait until they release their gametes and see what happens! Many 'gonochoric' species we are learning are actually sequential hermaphrodites and will change sex from year to year.
