Oyster reefs provide habitat for a diverse group of animals including fish, shrimp, worms and crabs. Oysters are food for larger fish, rays and crabs that are capable of crushing their shells.

Oysters are big business – Texas is the 2nd largest oyster producer in the U.S. The oysters also provide “ecosystem services”: they improve water quality by filtering phytoplankton and excess nutrients, and the oyster reefs can form a protective breakwater that stabilizes the shoreline and protects against erosion.
