Oyster Shells

Today while driving, I saw a car with a magnet about recycling oyster shells. I had never heard of this before, but it really got me wondering what they could be recycled for.. I googled it, and I found some interesting information.

Baby oysters begin life as free-floating organisms but quickly settle to the bottom attaching themselves to hard surfaces. That's why oysters grow in clumps on pilings and concrete, but their favorite most productive place to grow is on other shells.

A mound of oyster shells placed in brackish water with good tidal flow will quickly become colonized by a multitude of marine organisms, including oysters. This mound, also called an oyster reef, serves a number of purposes - first and foremost, it helps produce oysters.
