Oysters

Ecology
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.

Economy
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.
