Oysters are among the defining elements of the culture of the lower Lake Pontchartrain Basin, predominantly in the area known as the Biloxi marsh. They are a component of an enormous interconnected economy, essential to the world renowned cuisine of New Orleans and the rest of south Louisiana, and their reefs are essential to the biodiversity of the Basin’s waters, especially those nearest the Gulf of Mexico.
