Ever heard of coral microfragmentation? It’s like giving corals a superhero power: grow faster by going smaller! 💥🪸
So… why all the slicing? 🔬✂️
When corals are cut into tiny pieces, they switch into rapid wound-healing mode, producing new tissue up to 25× faster than normal. Their edges expand quickly and can even fuse with neighboring microfragments, forming a larger, healthier colony faster than nature could do alone. ⚡️🧬
After cutting, each piece is fixed onto plugs and moved into our nursery systems, where stable conditions help them:
✔ Heal faster
✔ Avoid algae competition
✔ Grow into strong colonies ready for outplanting
We’ve been testing this technique with 12 SPS species across 10 genera (from Acropora cynthus to Syphastrea), cutting each mother colony into:
🔹 3 microfragments
🔹 3 traditional fragments
Once fixed onto plugs, they head to our coral nurseries to heal, grow and prepare for life back on the reef. 🌱🌊
And here’s where it gets really interesting… 👇
🌱Survival: both techniques performed equally well
🌱 Growth: traditional fragments grew faster overall, but species like Porites, Montipora, Leptastrea, Pavona, and Pocillopora (at 30 m!) matched or exceeded microfragments in certain conditions.

This shows that fragmentation isn’t one-size-fits-all. Techniques need to be adapted depending on:
• the coral genus,
• whether it’s branching, encrusting, or massive,
• and the depth they naturally thrive at.
Tiny cuts, big science, and even bigger hope for reef recovery 💙🪸
