What are the benefits of estuaries?
Estuaries are often the economic centers of coastal communities. Estuaries provide habitat for more than 75 percent of the U.S. commercial fish catch, and an even greater percentage of the recreational fish catch. The total fish catch in estuaries contributes billions of dollars a year to the U.S. economy.
