Summary

The Chesapeake Bay is the largest estuary in the United States, and lies off the Atlantic Ocean, surrounded by Maryland and Virginia. The bay is mostly known for its seafood production, especially blue crabs, clams and oysters. In the middle of the twentieth century, the bay supported 9,000 full-time watermen, according to one account. Today, the body of water is less productive than it used to be because of runoff from urban areas (mostly on the Western Shore) and farms (especially on the Eastern Shore and in the Susquehanna River watershed), over-harvesting, and invasion of foreign species. In contrast to harvesting wild oysters, oyster farming is a growing industry for the bay to help maintain the estuary's productivity as well as a natural effort for filtering impurities from the water in an effort to reduce the effects of man-made pollution.
