I reached out to Monsoon Aquatics for an update on this seasons coral spawning – they provided me with the following information.
Season Wrap Up
Every October for the past five years, the team at Monsoon Aquatics has embarked on the annual coral spawning season at their farm in Burnett Heads, Queensland, Australia. Strap on your head torches, pump the red lights, and let us take you through this year’s wrap-up…..
During the 2024-25 season, we spawned, settled, and grew out the following species:
- Acropora (microclados, tenuis, millipora and spathulata)
- Micromussa lordhowensis (Acan lords)
- Trachyphyllia geoffroyi
- Homophyllia australis (Scoly)
- Euphyllia glabrescens (Torch)
- Gonipora species
- Echinophyllia species (Chalice)
We currently have over 40,000 settled corals currently growing out from this spawn run! We have only kept our key species to grow out, such as scoly, acan, trachy, and torch.
Reef-building corals such as Acropora will be a key target species for conservation aquaculture, so getting experience with these corals has been very valuable. Spawning the Acropora species proved quite easy, which is promising for our future reef restoration projects.
Continuous Improvement
Each year, we are improving our systems, procedures, and ultimate production. This continual improvement has allowed us to experiment this season with selective breeding to produce (in theory) a higher number of chimera, ultra, and master-grade corals. The early results from our selective breeding trials with scolymia will be evident soon, so stay tuned.

Challenges
One thing we are learning about conservation aquaculture is that baby corals have a mind of their own and won’t always do as they are told or encouraged to! As our settlement and survival rates improve, we are faced with the new problem of too many recruits choosing the same spots to settle and grow.
This is particularly a problem when it comes to producing corals for deployment in reef restoration projects, as the baby corals need to be separated out to one or two per block for deployment devices. This is almost impossible when you get settlement like seen in this photo of Gold torch, these guys all chose the one end of the tile to settle.

So now we have decent settlement rates and survivorship. The next step is to get these guys to spread out a little. We have some ideas that we will employ during this year’s spawning runs.
Beautiful Mistakes
However, every cloud has a silver lining, and in this case, overcrowded settlement has produced the beautiful mistakes that are our unique scoly gardens. This is something we never find in the wild, it’s a direct result of our captive spawning.
We are also finding unusual color patterns that we rarely, if ever, see in the wild; maybe this has something to do with our higher survival rates in captivity compared to the wild; maybe natural selection doesn’t like some of these color morphs. Whatever the reason, we love our scoly gardens and the new color varieties our conservation aquaculture program is putting out.
