Oysters need cloisters!
This is Sandra Tsing Loh with the Loh Down on Science.
We’ve demolished MOST natural oyster reefs. To rebuild them, we usually just dump flat rocks underwater. Sure, rocks offer a place to attach, but without hiding spots, baby oysters are easy prey! What’s missing?
Enter Melanie Bishop and team at Macquarie University. They studied how wild oysters build their cities. The team 3-D printed sixteen reef “models” with varying ridge patterns and heights.
Eventually they found a “Goldilocks” combo! Artificial reefs with the right height and ridges boosted survival by thirty-five percent!
Wow! We’ve been tossing rocks like overconfident DIY-ers!
But oysters already perfected their predator-proof floor plans eons ago.
Talk about a pearl of wisdom!
